Summary of your 'study carrel' ============================== This is a summary of your Distant Reader 'study carrel'. The Distant Reader harvested & cached your content into a collection/corpus. It then applied sets of natural language processing and text mining against the collection. The results of this process was reduced to a database file -- a 'study carrel'. The study carrel can then be queried, thus bringing light specific characteristics for your collection. These characteristics can help you summarize the collection as well as enumerate things you might want to investigate more closely. This report is a terse narrative report, and when processing is complete you will be linked to a more complete narrative report.

Although, in view of the crucial regulatory function of CD4 cells and the important role of CDS cells as cytotoxic effector cells during a virusspecific immune response, the results cannot unequivocally exclude the interpretation that susceptibility of the immunosuppressed animals may be due to the absence of proper immune effector mechanisms, the lack of clearance of the virus in the peritoneum and liver of AI] treated and infected mice (Figure 1) , which leads to high rates of mortality (Table 1) , may be attributed to the lack of IFN-y in the serum or peritoneal exudate of them (Fig. 3) , which has been shown in vitro to be effective to restrict the MHV3 growth in target cells such as macrophages (6, 7, 9) . doi = 10.1016/s0171-2985(11)80089-6 id = cord-278397-u33x4jaw author = Abe, Takayuki title = Negative Regulation of Cytosolic Sensing of DNA date = 2018-10-29 keywords = IFN; dna; response; sting summary = Recent efforts have focused on identifying relevant immune surveillance sensors and components of downstream signaling-Toll-like receptors (TLRs) and their cognate ligands, cytosolic sensing of RNA (primary mediated by the RIG-I/IPS-1 axis), cytosolic sensing of DNA (primary mediated by the cGAS/STING axis), and the inflammasome pathway (primary mediated by NOD-like receptors; NLRs) (Broz and Monack, 2013; Kieser and Kagan, 2017; Kumar et al., 2011a ). It has also been suggested that chronic cGAS/STING activation induced by self DNA may be responsible for induction of aberrant inflammatory diseases like systemic lupus erythematosus (SLE), Aicardi-Goutières syndrome (AGS), and polyarthritis (Barber, 2015; Crowl et al., 2017) . Use of DNA damage induced agents like 7,12-dimethylbenz-α-anthracene (DMBA) has helped shed light on the underlying events initiate the DNA damage-induced immune response via cytosolic DNA sensing pathway and implicates nucleosome leakage in eliciting cGAS/STING-dependent signal activation via recognition of self-DNA (Barber, 2015) . doi = 10.1016/bs.ircmb.2018.09.002 id = cord-276350-lcl9jn35 author = Acharya, Dhiraj title = Dysregulation of type I interferon responses in COVID-19 date = 2020-05-26 keywords = IFN; SARS summary = In a mouse model of SARS-CoV infection, local IFN responses in the lungs were delayed relative to peak viral replication, which impeded virus clearance and was associated with the development of CRS 5 . By contrast, IFNAR inhibition enhanced the recruitment of neutrophils to the lungs in MERS-CoV-infected mice, leading to elevated production of pro-inflammatory cytokines 6 . While patients with severe COVID-19 showed profound depletion and functional exhaustion of NK cells 8 , it is unclear whether this NK cell dysfunction is due to dysregulation of IFN responses. It is thus tempting to speculate that the deficient or dysregulated IFN responses elicited by SARS-CoV-2 infection may influence the generation of T reg cells during the recovery phase of COVID-19.

IFN, like the other type I IFNs, might be responsible of decreased mortality in females because of its antiviral effects. The JAK/STAT pathway responds to type I IFN secreted from neighboring cells and SARS-CoV proteins have been shown to affect this pathway before (Frieman and Baric, 2008) . JAK-STAT signal blocking by baricitinib (a selective JAK1 and JAK2 inhibitor) produces an impairment of IFN-mediated antiviral response, with a potential facilitating effect on the evolution of SARS-CoV-2 infection.

Binding to IFNARs leads to the activation of the Janus kinase-signal transducer and activator of transcription proteins (JAK-STAT) signaling pathway and the formation of the interferon-stimulated gene factor 3 (ISGF3) complex, with the subsequent expression of IFN-stimulated genes [3] that establish an antiviral state and play important roles in determining the host innate and adaptive immune responses [4] . In the following sections, we discuss the antiviral mechanisms mediated by ISGylation of both viral and cellular proteins, with a focus on mitochondrial proteins, as we recently showed that ISG15 modulates essential mitochondrial metabolic processes such as respiration and mitophagy in macrophages, with important implications for innate immune responses [29] . doi = 10.3390/v10110629 id = cord-023375-x4p187u7 author = Alitalo, A. title = Lysine‐Dependent Binding of OspE to the C‐terminus of Factor H Mediates Complement Resistance in Borrelia burgdorferi date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423aj.x id = cord-271114-hv3gwvdi author = Allam, Gamal title = Neonatal infections in Saudi Arabia: Association with cytokine gene polymorphisms date = 2015-04-22 keywords = EOS; IFN; IL-6; TNF summary = The objective of this study was to investigate single nucleotide polymorphism (SNP) in the interleukin (IL)-1β –31 T/C, IL-6 –174 G/C, tumor necrosis factor α (TNF-α) –308 G/A, and interferon γ (IFN-γ) +874 A/T genes for their possible association with susceptibility to early onset sepsis (EOS) in Saudi newborn infants. Our results show that the circulating IL-1β, IL-6, TNF-α, and IFN-γ were significantly (p < 0.001) elevated in EOS patients compared to suspected and sepsis-free control groups; and IL-1β –31C, IL-6 –174G, TNF-α –308G, and IFN-γ +874A alleles were associated with EOS in Saudi infants. Therefore, the primary aim of the current study was to investigate SNPs in the IL-1β -31 T/C (rs1143643), IL-6 -174 G/C (rs1800795), TNF-α -308 G/A (rs1800629), and IFN-γ +874 A/T (rs2430561) genes for their possible association with susceptibility to EOS in Saudi newborn infants.

Although CEF do not possess receptors for IFN-λ, slight temporal expression of DEGs in response to chIFN-λ treatment signifies its antiviral potential in primary cells. Furthermore, studies have also revealed that a high degree of cell type specificity in receptor-ligand interactions make avian IFNs distinct from mammalian IFNs. Recently, it has been established that chicken IFN-λ inhibits low pathogenic influenza virus replication in CEFs; however, as compared to chIFN-γ and chIFN-β, higher doses are required to induce ISGs and maintain the strong antiviral state in the cells [14] . Our data suggest that significant antiviral, cell cycle regulators, and biologically active genes are expressed in response to administered chicken IFN. doi = 10.3390/genes10020145 id = cord-023411-iszb5qlk author = Astrinidou‐Vakaloudi, A. title = Presence of Helicobacter pylori Antibodies in Haemodialysis Patients date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423p.x id = cord-341478-bicg5ozr author = Aurisicchio, L title = Regulated and prolonged expression of mIFNα in immunocompetent mice mediated by a helper-dependent adenovirus vector date = 2002-01-30 keywords = Dox; IFN; TET summary = To explore the regulated transgene expression in the context of a helper-dependent vector, we constructed the HD-TET-IFN vector, containing the mIFNα gene under the control of the tetracycline inducible transactivator rtTA2(s)-S2. In addition, C57/B6 mice injected at low HD-TET-IFN doses resulted in Doxmediated regulation of liver restricted mIFN␣ expression, which was associated with induction of antiviral genes. These results indicate that HD-TET-IFN allowed a significant expression of mIFN␣ controlled in vitro by Dox. To verify the efficiency and persistence of mIFN␣ secretion, C57/B6 mice were injected i.v. with 1.4 × 10 10 pp of HD-IFN or HD-TET-IFN and the mIFN␣ released in the serum was measured over time.

In EBOV infected Ifnar(-/-) mice, however, uninhibited viral replication and elevated proinflammatory factor expression ensued, irrespective of VLP treatment, supporting the view that type I IFN signaling helps to limit viral replication and attenuate inflammatory responses. Further analyses showed that VLP protection requires the transcription factor, IRF8 known to amplify type I IFN signaling in dendritic cells and macrophages, the probable sites of initial EBOV infection. The aim of this study was to further investigate molecular bases of postexposure protection by VLPs. Based on our previous report that VLPs stimulate type I IFN expression in DCs and macrophages, in vitro, we focused on the role of type I IFN signaling, and found that post-exposure VLP treatment leads to accelerated activation of IFN signaling, resulting in early induction of ISGs. Significantly, VLP stimulated ISG induction coincided with the attenuation of proinflammatory cytokine surge in EBOV infected mice. doi = 10.1371/journal.pone.0118345 id = cord-308932-pp8etmwq author = Baker, M.

CONCLUSIONS: These results suggest the possibility that sporadic anti-cytokine autoantibodies in some subjects may cause an autoimmune immunodeficiency syndrome leading to uncontrolled VZV reactivation, nerve damage and subsequent PHN. High levels of neutralizing anti-IFN-γ autoantibodies were also detected in patients with disseminated nontuberculous mycobacteria and other opportunistic infections, including both with localized and disseminated VZV reactivation [14, 15] . The finding that several patients each harbored single, neutralizing autoantibodies against interferon-α, GM-CSF or IL-6 suggests that anti-cytokine immunodeficiency may contribute to development of PHN. Particularly relevant was the finding of six PHN patients (one against anti-IFN-α, three against IFN-γ, one against GM-CSF, and one against IL-6) with high levels of autoantibodies greater than 100,000 LU that might have potential neutralizing activity against the target (Fig. 1) . doi = 10.1186/s12967-015-0695-6 id = cord-275643-lbikoyo3 author = Beidas, Meshal title = Effect of Human Coronavirus OC43 Structural and Accessory Proteins on the Transcriptional Activation of Antiviral Response Elements date = 2018-07-24 keywords = IFN; OC43 summary = The expression of antiviral genes involved in the type I IFN and NF-κB signaling pathways was also downregulated in the presence of HCoV-OC43 structural or accessory proteins.

Following SeV challenge of HEK-293 cells, the expression of genes involved in the type I IFN and NF-κB signaling pathways was downregulated in the presence of HCoV-OC43 structural or accessory proteins (Fig. 4) . Similar to influenza A NS1 protein, HCoV-OC43 structural (M and N) and accessory (ns2a and ns5a) proteins were able to inhibit the transcriptional activity of antiviral response elements, ISRE, IFN-β promoter, and NF-κB-RE, and to downregulate the expression of several genes involved in the activation of an antiviral response. doi = 10.1159/000490566 id = cord-255781-55zrmgxq author = Bergman, Scott J. title = Interferons as Therapeutic Agents for Infectious Diseases date = 2011-12-31 keywords = HCV; IFN; infection; interferon; treatment summary = doi = 10.1016/j.idc.2011.07.008 id = cord-023390-5hcgdlmt author = Bhuvanath, S. title = Inflammatory Cytokine Modulation of Cancer Cell Proliferation date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423bi.x id = cord-333955-bnzbppof author = Biesold, Susanne E. title = Type I Interferon Reaction to Viral Infection in Interferon-Competent, Immortalized Cell Lines from the African Fruit Bat Eidolon helvum date = 2011-11-30 keywords = IFN; ONNV; cell; figure summary = Here, we investigated interferon (IFN) response, -induction, -secretion and -signaling in epithelial-like cells of the relevant and abundant African fruit bat species, Eidolon helvum (E.

CONCLUSION: Taken together, our data demonstrated for the first time that PEDV infection of its target cell line, IECs, inhibited dsRNA-mediated IFN-β production by blocking the activation of IPS-1 in RIG-I-mediated pathway. PEDV failed to induce IFN-β expression and inhibited poly (I:C)-mediated IFN-β production in IECs Type I IFNs (IFN-α/β) are critical to the host antiviral innate immune response. In summary, the findings of the present study suggested that PEDV-infection in IECs inhibits dsRNA-induced IFN-β induction by interfering with IRF-3 activity associated with RIG-I-mediated signaling pathway. doi = 10.1186/s12985-015-0345-x id = cord-340475-h0q1m3ed author = Carnero, Elena title = Type I Interferon Regulates the Expression of Long Non-Coding RNAs date = 2014-11-06 keywords = IFN; IRF1; ISR2; ISR8; RNA; figure summary = Further validation showed that ISR2, 8, and 12 expression mimics that of their neighboring genes GBP1, IRF1, and IL6, respectively, all related to the IFN response.These genes are induced in response to different doses of IFNα2 in different cell lines at early (ISR2 or 8) or later (ISR12) time points.

Notably, increased expression of inflammatory mediators following infection with influenza virus as compared to hRSV has been observed in studies assessing human clinical samples and in vitro airway epithelial cell cultures [36] [37] [38] [39] . doi = 10.1093/infdis/jiy184 id = cord-347460-9vechh4x author = Chang, Feng-Yee title = Immunologic aspects of characteristics, diagnosis, and treatment of coronavirus disease 2019 (COVID-19) date = 2020-06-04 keywords = COVID-19; CoV; IFN; MERS; SARS; infection summary = Three components are crucial for SARS-CoV induced diseases: 1) the role of CD8+ T cells in defense against the virus, which causes apoptosis in the infected cells, 2) interactions of the virus with macrophages and dendritic cells, which initiate the early innate and subsequent adaptive immune responses, and 3) type I interferon (IFN) system, an innate response against viral infections, which can inhibit virus replication in the early phase. Existing information suggests that the SARS-CoV-infected airways and alveolar epithelial cells secrete abundant chemokines to attract immune cell infiltrations to the lungs, including macrophages and neutrophils, thereby causing damage due to high levels of proinflammatory cytokines and other mediators secreted by these cell types. After a decade of research on coronavirus, unfortunately, still there are no licensed vaccines, effective specific antivirals, nor drug combinations supported by high-level evidence to treat the infection, especially for newly emerging strains such as SARS-COV-2 [59] . doi = 10.1186/s12929-020-00663-w id = cord-327685-fymfqvp3 author = Channappanavar, Rudragouda title = Pathogenic human coronavirus infections: causes and consequences of cytokine storm and immunopathology date = 2017-05-02 keywords = IFN; MERS; SARS; respiratory summary = In contrast, highly pathogenic hCoVs such as severe acute respiratory syndrome CoV (SARS-CoV) and Middle East respiratory syndrome CoV (MERS-CoV) predominantly infect lower airways and cause fatal pneumonia. Severe pneumonia caused by pathogenic hCoVs is often associated with rapid virus replication, massive inflammatory cell infiltration and elevated pro-inflammatory cytokine/chemokine responses resulting in acute lung injury (ALI), and acute respiratory distress syndrome (ARDS). Although there is no direct evidence for the involvement of pro-inflammatory cytokines and chemokines in lung pathology during SARS and MERS, correlative evidence from patients with severe disease suggests a role for hyper-inflammatory responses in hCoV pathogenesis. Infection of non-human primates (NHPs) with SARS-CoV induced a dysregulated immune response resulting in increased disease severity in aged but not young NHPs, despite similar viral titers in the airways [67] .

Interestingly, we observed that ATMUV infection could trigger duck innate immune response including robust expression of particular type I and type III IFNs and IFITM family proteins. Our previous studies had shown that ATMUV infection effectively triggers the host innate immune response, including robust upregulation of type I and type III IFNs and some critical ISGs in chicken and CEF (Chen et al., 2016a) . To confirm these findings, DF-1 cell lines expressing specific shRNA targeting each of these IFITMs were infected with ATMUV and harvested at 36 hpi, followed by qRT-PCR assay to detect mRNA expression of viral genes. doi = 10.3389/fmicb.2017.00672 id = cord-326762-t89jtjmi author = Chen, Weiye title = Establishment of a stable CHO cell line with high level expression of recombinant porcine IFN-β date = 2011-06-30 keywords = CHO; IFN; PoIFN summary = title: Establishment of a stable CHO cell line with high level expression of recombinant porcine IFN-β Abstract A CHO cell clone (CHO-PoIFN-β) with stable porcine IFN-β expression under control of CMV promoter was selected under G418 pressure.

In all, these results demonstrated that PD-1 deficiency led to enhanced pathological damage by MHV-3 in the liver, spleen, lymph node and thymus, where higher levels of PD-1-positive cells were found after infection. Results showed that the expression of FGL2 was principally associated with CD31-positive endothelial cells, CD68-positive macrophages and CD11c-positive DCs. Surprisingly, significantly higher levels of FGL2 were observed after infection in all of PD-1-deficient organs, including the liver, thymus, spleen, lymph nodes, and serum than that in those from WT littermates.

In a mouse model of West Nile virus (WNV) infection, it was found that the permeability of the BBB increased in mice lacking IFNAR, especially in the hindbrain, which leads to an increase in viral entry, indicating that IFNAR signaling has important regulatory effects on BBB permeability in this brain region. Loss of astrocyte IFNAR signaling pathway can cause a variety of consequences, including increased expression of inflammatory cytokines and chemokines, which disrupt the blood-brain barrier during neurotropic viral infection [30] . In a mouse model of lethal West Nile virus (WNV) infection, Peli1 promotes the production of pro-inflammatory cytokines and chemokines in microglia and promotes the entry of T cells and macrophages into the CNS. doi = 10.1186/s12974-019-1443-2 id = cord-327135-4c2flue4 author = Chinnaswamy, S title = Gene–disease association with human IFNL locus polymorphisms extends beyond hepatitis C virus infections date = 2016-06-09 keywords = HCV; HIV; IFN; IFNL; SNP summary = Interferon (IFN) lambda (IFN-λ or type III IFN) gene polymorphisms were discovered in the year 2009 to have a strong association with spontaneous and treatment-induced clearance of hepatitis C virus (HCV) infection in human hosts. Three independent groups conducted genome-wide association studies (GWASs) involving treatment response to chronic hepatitis C virus (HCV) infections, in three different geographical regions of the world, and reported that single-nucleotide polymorphisms (SNPs) in the IFNL locus (Figure 1 ), had strong association with treatment-induced HCV clearance irrespective of ethnicity and geographical location of the hosts. 49 In stark contrast, a dominant model of inheritance (of the non-beneficial IFNL SNP minor allele) has consistently given the best explanation on the observed phenotypes in association studies with both spontaneous clearance and IFN-based treatment response in chronic HCV infections. doi = 10.1038/gene.2016.24 id = cord-023414-xxw5kptr author = Chistensen, H.

Poly (ICLC), a dsRNA, and CpG ODNs, molecular mimics for TLR3 and TLR9, respectively, have been reported to non-specifically stimulate the innate immune system and to provide protection against various bacterial and viral pathogens, including influenza. Mice treated with two doses of poly (ICLC), 48 h apart, up to 12 d prior to viral challenge were completely protected from infection, whereas survival rates decreased to 80, 40 and 0%, when pre-treatment was given 14, 16 or 20 d prior to virus challenge, respectively [32] . CpG ODN treatment of splenocytes from senescence-accelerated SAM-P1 strain of mice increased IFN-γ and administration in vivo generated virus-specific cytotoxic T lymphocyte responses, NK cell activation, virus-specific Ig isotype switch from IgG1 to IgG2a, increased viral clearance and survival following influenza viral challenge.

In both cell lines, SARS-CoV infection deregulated expression of cellular genes which may be important for the intestinal pathogenesis of SARS. To investigate whether ACE2 is a functional receptor for SARS-CoV in intestinal epithelial cell cultures, the cells were pre-treated for 60 min at 37°C with goat antibody directed against the human ACE2 ectodomain (R&D Systems; Wiesbaden-Nordenstadt, Germany). SARS-CoV infection of Caco-2 cells up-regulated OAS2 and MXA but not PKR genes. The discrepancy between transcriptional activation of IFN-induced genes and the ability of SARS-CoV to replicate in Caco-2 cells could be explained by the existence of a specific viral mechanism for escaping IFNinduced anti-viral effects common to most viruses [28] . This justifies the use of intestinal cell lines as a model to study the direct effects of SARS-CoV infection on gene expression in permissive human cells. doi = 10.1007/s00018-004-4222-9 id = cord-315328-8g40ukml author = Clementi, Nicola title = Interferon-β-1a Inhibition of Severe Acute Respiratory Syndrome–Coronavirus 2 In Vitro When Administered After Virus Infection date = 2020-06-19 keywords = IFN; SARS summary = In this report, we demonstrate that IFN-β-1a was highly effective in inhibiting in vitro SARS-CoV-2 replication at clinically achievable concentration when administered after virus infection. In this report, we demonstrate that IFN-β-1a was highly effective in inhibiting in vitro SARS-CoV-2 replication at clinically achievable concentration when administered after virus infection. In the current study, we assessed its anti-SARS-CoV-2 activity in vitro to give a preclinical background to clinical trials evaluating the possible therapeutic role of IFN-β-1a in patients with coronavirus disease 2019 (COVID-19). Vero E6 cells were treated with concentrations ranging from 5000 to 0.01 IU/mL of IFN-β-1a 1 hour after inoculation with SARS-CoV-2 and monitored for cytopathic effect and real-time-PCR quantitative evaluation at 48, 72, and 96 hours after infection.

In these cells, the HCV-induced miR-21 has been recently reported to be involved in evasion of IFN-I production and stimulation of HCV replication, upon suppression of MyD88 and IRAK1 expression, that is required for the TLR7-mediated sensing of the virus [100] . Amongst RNA viruses that, as HCV, can establish a persistent infection, HIV-1, a lentivirus from the Retroviridae family, represents a paradigm for its ability to prevent or circumvent the innate immune response mediated by IFN-I. Overall, viruses as HCV and HIV-1 have evolved nifty strategies to dampen the host innate response in cells where a productive infection may take place, while they induce infection-independent mechanisms in non-permissive cells to facilitate the viral life cycle and promote a chronic inflammation. doi = 10.1016/j.smim.2015.03.005 id = cord-002201-pnw5ytj4 author = Corredor, Juan C title = N-Myc expression enhances the oncolytic effects of vesicular stomatitis virus in human neuroblastoma cells date = 2016-03-16 keywords = IFN; myc; tet-21n summary = doi = 10.1038/mto.2016.5 id = cord-292593-apdyaujt author = Coulter-Mackie, Marion title = In vivo and in vitro models of demyelinating diseases XII.

Since upon infection of RN2-2 cultures with JHMV at 39.5"C and maintenance in a state of latency at that temperature for several days, the cells commenced yielding pfu upon shift down to 32.5"C (Lucas et al., 1978) , these data suggest that penetration and eclipse of the virus inoculum must have occurred normally at 39.5"C and restriction most probably developed at a subsequent stage. It is very significant that during incubation at the restrictive temperature for as long as 7 days and beyond, when RN2-2 cells had multiplied through 6-7 generations, the 56K antigen was readily detectable (channel I), implying that during latency, in the absence of infectious virus production, translation into JHMV nucleocapsid protein continued. doi = 10.1016/0168-1702(85)90049-8 id = cord-304330-egvdvvtx author = Damsky, William title = When interferon tiptoes through COVID-19: Pernio-like lesions and their prognostic implications during SARS-CoV-2 infection date = 2020-06-19 keywords = IFN summary = William Damsky MD, PhD 1,* , Danielle Peterson MD 1 Brett King MD, PhD 1,* 4 5 has suggested that SARS-CoV-2 infection is sometimes characterized by a muted anti-40 viral Type I and III interferon (IFN) response, 6,7 which may explain progression to 41 severe clinical manifestations in some patients; a robust Type I IFN response was 42 associated with rapid viral clearance and bland disease course.

Since STAT1 was phosphorylated following SARS-CoV infection and IFN-α2b injection, we investigated select IRG expression by qRT-PCR following in vitro stimulation of ferret peripheral whole blood with IFN-α2b. These gene expression and STAT1 phosphorylation findings suggested that robust IFN responses were activated following SARS-CoV infection 2 days post-infection. The comparison of microarray results between the lung tissue of IFN-α2b and SARS-CoV ferrets at day 1 revealed commonalities in the expression patterns of most IRGs.

Natural killer (NK) cells are innate lymphocytes that play a critical role in the early antiviral response, secreting effector cytokines and clearing infected cells. This review describes the role of Natural killer (NK) cells, a critical component of early antiviral immunity, in the establishment of tolerance to viral infections in natural hosts, as well as their role in the development of disease in nonnatural hosts.

PKR can directly sense dsRNA generated during viral replication to induce Fas expression and FADD-dependent apoptosis [52] , as well as inhibit host and viral protein translation through the phosphorylation of eIF2a [53] in IAV-infected cells [54] . Additionally, pandemic and highly virulent strains of the virus, including HPAI and the 1918 H1N1 strain, are known to completely exhaust the replicative niche of epithelial cells of the lung over the course of infection as a by-product of overly exuberant replication and failure of immune response to control viral propagation. Collectively, these findings suggest that in contrast to the biphasic role of epithelial cell apoptosis in preventing or promoting pathogenesis, highly virulent IAV rapidly infects and induces early death in pulmonary M4 to suppress antiviral responses. doi = 10.1016/j.micinf.2018.03.005 id = cord-023441-q83y12sk author = Draborg, H. title = Recominant Expression and Immunological Characterization of House Dust Mite Allergen Der P 1 date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423ag.x id = cord-252528-rgnhfcbx author = Du, Fenghe title = COVID-19: the role of excessive cytokine release and potential ACE2 down-regulation in promoting hypercoagulable state associated with severe illness date = 2020-07-16 keywords = ACE2; IFN; IL-6; SARS; covid-19 summary = • Anti-inflammatory therapies, including tocilizumab, chloroquine, and hydroxychloroquine, which can be promising treatment to control excessive cytokine release in severe COVID-19, have the potential to reduce the risk of vascular thrombotic events, but more clinical data are needed for optimum instruction of drug use and drug selection. By interpreting the pathological mechanisms, we aim to illustrate that excessive pro-inflammatory cytokine release and potential ACE2 down-regulation can promote the hypercoagulable state in severe COVID19 , and propose that the anti-inflammatory medications, as well as ACEI/ARB, can benefit severe COVID-19 patients by reducing the risk of vascular thrombotic events. doi = 10.1007/s11239-020-02224-2 id = cord-001273-plz1ja2e author = Dussurget, Olivier title = The bacterial pathogen Listeria monocytogenes and the interferon family: type I, type II and type III interferons date = 2014-04-28 keywords = IFN; III; Listeria; type summary = doi = 10.3389/fcimb.2014.00050 id = cord-003855-so8xl199 author = Ebert, Gregor title = Virology Downunder, a meeting commentary from the 2019 Lorne Infection and Immunity Conference, Australia date = 2019-09-02 keywords = IFN; Infection summary = The bat innate immune response appears to be ''pre-activated'' with higher basal levels of type I interferon expression, in contrast to humans, who are very quick responders to viral infections, but require a lot more dampening of their immune signals afterwards to get back to basal levels. demonstrated that bats'' response to stress in form of viral infections is more targeted and thus potentially more effective by numerous adaptions and modifications of the innate immune system.

As inhibition of necroptosis does not affect IAV control, while Mlkl-/-Fadd-/-mice exhibit marked susceptibility to IAV-induced lethality [78] , it signifies that RIPK1/3-mediated apoptosis is a major form of host protection against IAV infection. A number of studies have used purified pathogen components such as LPS to investigate the outcomes of RIPK1/3-mediated inflammasome signaling, which appear to be largely dependent on cell type, stimulus, and the availability or functional activity of certain host signaling proteins [65, [123] [124] [125] [126] [127] . Overall this suggests that RIPK2 plays an important role in both innate and adaptive immunity to infection [137, 151] , and that RIPK2 was mediating these responses via NOD1/2 and not directly via TLR activation [140] . doi = 10.1016/j.semcdb.2020.08.005 id = cord-256838-8rzibpbl author = Eng, Yi Shin title = Unraveling the Molecular Mechanism of Traditional Chinese Medicine: Formulas Against Acute Airway Viral Infections as Examples date = 2019-09-27 keywords = GGT; IFN; MXGST; TCM; TNF; Tang; effect summary = doi = 10.3390/molecules24193505 id = cord-325989-nf6ouaq3 author = Es-Saad, Salwa title = Regulators of innate immunity as novel targets for panviral therapeutics date = 2012-09-24 keywords = HCV; IFN; TLR; immune summary = The successes obtained with Toll-like receptor (TLR) agonists in activating immune cells and as adjuvant for prophylactic vaccines against different viruses paved the way to targeted immunomodulatory therapy. The successes obtained with Toll-like receptor (TLR) agonists in activating immune cells and as adjuvant for prophylactic vaccines against different viruses paved the way to targeted immunomodulatory therapy. Better characterization of pathogen-induced immune disorders and newly discovered regulators of innate immunity have now the potential to specifically withdraw prevailing subversion mechanisms and to transform antiviral treatments by introducing panviral therapeutics with less adverse effects than IFN therapies. In the near future, targeting specific regulators of PRR-mediated innate response to withdraw viral subversion mechanisms, and access to novel surrogate measurable effector markers, hold the promise of new panviral therapeutics that will minimize adverse effects associated with type I IFN therapy. doi = 10.1016/j.coviro.2012.08.009 id = cord-302340-pw2xqhwa author = Feeley, Eric M. title = IFITM3 Inhibits Influenza A Virus Infection by Preventing Cytosolic Entry date = 2011-10-27 keywords = Fig; IFITM3; IFN; MDCK; cell summary = Therefore, we have hypothesized that IFITM proteins inhibit susceptible virus families (Orthomyxoviridae, Flaviviridae, Rhabdoviridae, Filoviridae, and Coronaviridae) during the envelope-dependent early phase of the infection cycle, which extends from viral binding to cell surface receptors through the creation of the fusion pore between viral and host membranes [14, 19, 20] . B) MDCK cells stably overexpressing IFITM3 (MDCK-IFITM3) or empty vector control cells (MDCK-Vector) were exposed for 2 h to viral pseudoparticles containing a BLAM-Vpr and expressing either the HA and NA envelope proteins of Influenza A virus (WSN/33, H1N1pp) or the VSV-G envelope protein (VSV-Gpp), then loaded with CCF2. Our assays showed that incoming influenza A viruses were retained in the expanded acidic compartments of both the IFITM3 overexpressing cell lines as well as the IFN-c-treated MEFs, and that IFITM3 partially localized to these structures ( Fig. 2-4, S2-4, S6) . doi = 10.1371/journal.ppat.1002337 id = cord-343515-fad1yyqx author = Felgenhauer, Ulrike title = Inhibition of SARS–CoV-2 by type I and type III interferons date = 2020-10-09 keywords = IFN; SARS; Vero summary = For SARS-CoV-2 (dark gray bars), statistically significant negative correlation coefficients (CC) were obtained for both cell lines, indicating that viral replication is increasingly inhibited by IFN-a. Observations were similar when the input MOI was reduced to 0.001 (Fig. S1 ), except that titers of SARS-CoV-1 in Calu-3 cells were already very low in the absence of any IFN-a, resulting in a nonsignificant effect of additional IFN. Our data thus indicate that (i) if anything, ruxolitinib is an enhancer rather than an inhibitor of SARS-CoV-2 multiplication, and (ii) the boosting effect is most likely due to inhibition of the antiviral JAK/ STAT signaling pathway, because it is not present in the IFN induction-deficient Vero E6 cells. For the statistical testing of the dose-response effect of IFN (type I and III) against SARS-coronaviruses, the typical regression procedures were not applicable because of several values below the detection limit and some ties in the data. doi = 10.1074/jbc.ac120.013788 id = cord-002068-e071ciil author = Feng, Min title = Innate Immune Responses in ALV-J Infected Chicks and Chickens with Hemangioma In Vivo date = 2016-05-25 keywords = ALV; IFN; figure summary = doi = 10.3389/fmicb.2016.00786 id = cord-314019-8n0jafsk author = Feng, Qian title = Induction and suppression of innate antiviral responses by picornaviruses date = 2014-07-18 keywords = IFN; MDA5; RNA summary = doi = 10.1016/j.cytogfr.2014.07.003 id = cord-000660-tsvzg0ax author = Fensterl, Volker title = Interferon-Induced Ifit2/ISG54 Protects Mice from Lethal VSV Neuropathogenesis date = 2012-05-17 keywords = IFN; RNA; VSV; figure; ifit2 summary = Interferon protects mice from vesicular stomatitis virus (VSV) infection and pathogenesis; however, it is not known which of the numerous interferon-stimulated genes (ISG) mediate the antiviral effect. In contrast, in acute infection by viruses that cause severe pathogenesis and death within a few days after infection, protection is primarily provided by the intrinsic antiviral actions of IFN-induced proteins encoded by the hundreds of IFN-stimulated genes (ISGs) [10] [11] [12] , several of which often contribute to the overall effect of IFN against a given virus. From the above observations, we conclude that after intranasal infection by VSV, Ifit2 protects mice from neuropathogenesis by suppressing replication or spread of the virus in brain neurons. In the complete absence of type I IFN action in the IFNAR 2/2 mice, intranasally infected VSV replicated vigorously not only in brains, but also in livers and lungs ( Figure 7A-C) . doi = 10.1371/journal.ppat.1002712 id = cord-289413-mbrw85og author = Flego, Michela title = Intracellular human antibody fragments recognizing the VP35 protein of Zaire Ebola filovirus inhibit the protein activity date = 2019-09-05 keywords = EBOV; ELISA; Ebola; IFN; VP35 summary = doi = 10.1186/s12896-019-0554-2 id = cord-016343-wc3i54fc author = Frese, Michael title = Interferon-Induced Effector Proteins and Hepatitis C Virus Replication date = 2008 keywords = HCV; IFN; PKR; RNA summary = RdRp, RNA-dependent RNA polymerase; IRES, internal ribosome entry site; 5BSL3.2, stem loop 3.2 within the coding sequence of NS5B normally result in the production of type I IFNs and the subsequent expression of IFN-induced effector proteins, which in turn would establish an antiviral state in the IFN-producing cell itself and in neighboring cells. Since MxA has the ability to efficiently inhibit a variety of different RNA viruses, MxA was the first IFN-induced effector protein to be analyzed for its antiviral activity in the HCV replicon system (Frese et al., 2001) . Rather indirect evidence that the OAS/RNase L pathway may indeed target HCV replication/translation was recently provided by Taguchi and co-workers, who reported that the N-terminal portion of NS5A (amino acids 1 to 148), which lacks the so-called PKR-binding domain, binds to OAS proteins and there by counteract the antiviral activity of IFN-α (Taguchi et al., 2004) . doi = 10.1007/978-0-387-71376-2_6 id = cord-003261-fz8ucwwm author = Freundt, Eric C. title = Innate Immune Detection of Cardioviruses and Viral Disruption of Interferon Signaling date = 2018-10-12 keywords = EMCV; IFN; MDA5; PKR summary = doi = 10.3389/fmicb.2018.02448 id = cord-289101-ko1knslk author = Fu, Weihui title = An open-label, randomized trial of the combination of IFN-κ plus TFF2 with standard care in the treatment of patients with moderate COVID-19 date = 2020-09-20 keywords = COVID-19; IFN; SARS; TFF2 summary = Our previous clinical pilot study indicated that aerosol inhalation of IFN-k plus TFF2 is a safe treatment and is able to significantly facilitate clinical improvement, including cough relief, CT imaging improvement, and viral RNA reversion, thereby resulting in an early release from hospitalization without induction of a proinflammatory response [20] .

In this trial, any AE from the beginning of aerosol inhalation to 5 days after the end of the last aerosol inhalation were taken as an adverse event during treatment (TEAE); The secondary objective of the pilot study was to evaluate the clinical efficacy of IFN-k plus TFF2 as compared to the control group as assessed by days of hospitalization staying, CT imaging improvement and cough relief time and negative reversion of viral RNA after 10 days of treatment. doi = 10.1016/j.eclinm.2020.100478 id = cord-257077-cdnkk6ou author = Gabor, Kristin A. title = Super Resolution Microscopy Reveals that Caveolin-1 Is Required for Spatial Organization of CRFB1 and Subsequent Antiviral Signaling in Zebrafish date = 2013-07-09 keywords = CRFB1; FPALM; IFN; SHRV; figure summary = doi = 10.1371/journal.pone.0068759 id = cord-338602-6n309bnp author = Gadotti, Ana Carolina title = IFN-γ is an independent risk factor associated with mortality in patients with moderate and severe COVID-19 infection date = 2020-09-23 keywords = IFN; covid-19; patient summary = title: IFN-γ is an independent risk factor associated with mortality in patients with moderate and severe COVID-19 infection We proposed a study in patients with moderate to severe COVID-19 infection to evaluate the interleukin patterns and its role as prognosis factors.

Furthermore, qPCR analysis found depletion of Med23 inhibited the induction of IFN-l expression following HSV-1 infection of A549 cells in comparison to cells transfected with the RSCF siRNA control ( Figure 4e ). doi = 10.1371/journal.ppat.1003514 id = cord-329424-hmsidrc7 author = Grunwell, Jocelyn R. title = Differential type I interferon response and primary airway neutrophil extracellular trap release in children with acute respiratory distress syndrome date = 2020-11-04 keywords = IFN; ISG; PARDS; net; stat1 summary = doi = 10.1038/s41598-020-76122-1 id = cord-013481-3zwq67do author = Guo, Kejun title = Qualitative Differences Between the IFNα subtypes and IFNβ Influence Chronic Mucosal HIV-1 Pathogenesis date = 2020-10-16 keywords = CD4; Fig; HIV-1; IFN; PWH summary = The Type I Interferons (IFN-Is) are innate antiviral cytokines that include 12 different IFNα subtypes and IFNβ that signal through the IFN-I receptor (IFNAR), inducing hundreds of IFN-stimulated genes (ISGs) that comprise the ''interferome''. Since IFNβ, and not IFNα, is upregulated during chronic HIV-1 infection in the gut, we compared core ISGs and IFNβ-specific ISGs from colon pinch biopsies of HIV-1-uninfected (n = 13) versus ageand gender-matched, antiretroviral-therapy naïve persons with HIV-1 (PWH; n = 19). We recently reported that during chronic, untreated HIV-1 infection, IFN-I inducible antiretroviral genes APOBEC3G, BST2 and MX2, as well as IFNβ, but not IFNα, were expressed to significantly higher levels when compared to HIV-1 uninfected individuals [38] . These data suggest that increased IFNβ in the gut of chronic PWH may drive genes associated with sustained ISG expression, antigen processing, T cell activation, inflammation and immune exhaustion. doi = 10.1371/journal.ppat.1008986 id = cord-282242-5tkhjiwl author = Gómez-Laguna, J. title = Cytokine Expression by Macrophages in the Lung of Pigs Infected with the Porcine Reproductive and Respiratory Syndrome Virus date = 2009-08-19 keywords = IFN; PRRSV; TNF summary = doi = 10.1016/j.jcpa.2009.07.004 id = cord-329366-xuszdrsa author = Hackbart, Matthew title = Coronavirus endoribonuclease targets viral polyuridine sequences to evade activating host sensors date = 2020-04-07 keywords = Fig; IFN; MDA5; PUN; RNA summary = In this study, we show that CoV EndoU activity limits the abundance and length of the polyuridine (polyU) extension on 5′-polyU-containing, negative-sense (PUN) RNAs for both the beta-CoV mouse hepatitis virus strain A59 (MHV-A59) and the alpha-CoV PEDV. Overall, we propose a mechanism for EndoU, which is to cleave polyU sequences from PUN RNAs, thus limiting the formation of a PAMP and impeding the ability of MDA5 to activate the innate immune response to infection. EndoU Activity Limits Abundance and Length of PUN RNAs. Previous studies showed that the 5′ end of the CoV negative-sense RNA contains polyU extensions (35) , and that EndoU cleaves at uridine residues (22, 25, (27) (28) (29) (30) . We found that the products generated from positive-sense RNA were similar between wild-type and EndoUmut viruses, consistent with our previous results indicating that the polyA tail is not cleaved by EndoU activity (Fig. 5C ). doi = 10.1073/pnas.1921485117 id = cord-007417-az8xd66p author = Hansbro, Nicole G. title = Understanding the mechanisms of viral induced asthma: New therapeutic directions date = 2008-01-29 keywords = AHR; CD8; IFN; RSV; infection; respiratory; th2; virus summary = doi = 10.1016/j.pharmthera.2007.11.002 id = cord-023392-axd0901z author = Hansen, T.

SARS-CoV-1 ORF6 is about 4-fold less potent in antagonizing type I IFN signaling (Fig. 243 4b) but induces higher levels of autophagy (Fig. 4c) .

GFAPcR1D and wt mice were compared at the peak of acute disease to determine if IFN-c signaling altered astrocyte activation or CNS inflammation. Despite elevated demyelination and axonal loss in the absence of IFN-c signaling to astrocytes, spinal cords showed no evidence of differential astrocyte activation by either immunohistochemistry (Fig. 4 ), or differences in GFAP mRNA expression during the peak of acute disease (Fig. 5 ). Although demyelination was increased in the CNS of GFAPcR1D mice, the extent of astrocyte activation associated with spinal cord white matter lesions was similar in both groups ( Fig. 6 ; ,60 GFAP + cells/mm 2 ). doi = 10.1371/journal.pone.0042088 id = cord-023388-btbf6wkg author = Hoffmann, H.

As expected, this upregulation inhibits IFN-I-induced genes in human microvascular endothelial cells; however, whether USP18 plays a role in controlling bacterial infection has not yet been fully clarified. Because DCs express more USP18 than do other types of cells, the lack of a response to the antiviral effect of IFN-I leads to augmented viral replication and a sufficient amount of autoantigen. doi = 10.1038/cddis.2016.326 id = cord-312438-zr9zx7pv author = Hoo, Regina title = Innate Immune Mechanisms to Protect Against Infection at the Human Decidual-Placental Interface date = 2020-09-10 keywords = IFN; SCT; cell; human; infection summary = doi = 10.3389/fimmu.2020.02070 id = cord-283505-ousbar6c author = Horman, William S.

While the day 6 ferret which showed worsened disease progression did exhibit the most severe lung pathology, the lack of viral antigen in and around these lesions (Supplementary Figure 1) means they cannot conclusively be classified as being caused by the influenza infection, and thus we are hesitant to classify disease presentation in this ferret as like a high pathogenicity infection based on the histopathology findings regardless of the increase in clinical signs.

Furthermore, TGEV PL1 exerted deubiquitinase (DUB) activity which strongly inhibited the retinoic acid-induced gene I(RIG-1-) and stimulator of interferon gene(STING-) dependent IFN expression. In the present study, we found that TGEV PL1 encoded by the replicase gene could suppress the IFN-expression and inhibit the nuclear translocation of interferon regulatory factor 3 (IRF3) and exerted deubiquitinase (DUB) activity which strongly inhibited the retinoic acid-induced gene I-(RIG-1-) and stimulator of interferon gene-(STING-) dependent IFN expression. We observed the inhibition of SeV-induced IFN-promoter activation in the presence of PL1, similar to the antagonistic function of NL63 PLP2 and porcine epidemic diarrhea virus (PEDV) PLP2, clearly indicating that TGEV PL1 could act as an interferon antagonist. doi = 10.1155/2017/7089091 id = cord-002937-7xauocti author = Huang, Chung-Guei title = A pilot study on primary cultures of human respiratory tract epithelial cells to predict patients’ responses to H7N9 infection date = 2018-02-20 keywords = H7N9; IFN; IL-8; RNA; virus summary = doi = 10.18632/oncotarget.24537 id = cord-023407-s85g7g0x author = Huang, Y.‐M. title = Anti‐Inflammatory Liver X Receptors and Related Molecules in Multiple Sclerosis Patients from Sardinia and Sweden date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423d.x id = cord-351532-2yd4wg9v author = Huang, Yin-Qiu title = No Statistically Apparent Difference in Antiviral Effectiveness Observed Among Ribavirin Plus Interferon-Alpha, Lopinavir/Ritonavir Plus Interferon-Alpha, and Ribavirin Plus Lopinavir/Ritonavir Plus Interferon-Alpha in Patients With Mild to Moderate Coronavirus Disease 2019: Results of a Randomized, Open-Labeled Prospective Study date = 2020-07-14 keywords = IFN; LPV; RBV; SARS summary = title: No Statistically Apparent Difference in Antiviral Effectiveness Observed Among Ribavirin Plus Interferon-Alpha, Lopinavir/Ritonavir Plus Interferon-Alpha, and Ribavirin Plus Lopinavir/Ritonavir Plus Interferon-Alpha in Patients With Mild to Moderate Coronavirus Disease 2019: Results of a Randomized, Open-Labeled Prospective Study The proportion of patients with SARS-CoV-2 nucleic acid negativity in the LPV/r+IFN-α-treated group (61.1%) was higher than the RBV+ IFN-α-treated group (51.5%) and the RBV+LPV/r+IFN-α-treated group (46.9%) at day 14; however, the difference between these groups was calculated to be statistically insignificant.

RNase L specifically protected the brain stem from sustained infection and prevented spread of virus to microglia/macrophages located in spinal cord grey matter. The increased pathological changes in both brain stem and spinal cord thus correlated with the high mortality rates of RL 2/2 mice starting at day 9 p.i. The inability to directly link increased axonal damage with enhanced neuronal infection remains puzzling and supports dysregulation of oligodendrocyte function and/or neuroprotective functions of microglia as contributing factors to the severe pathological phenotype and clinical outcome. Numerous functions of RNase L, not directly associated with anti-viral activity, may contribute to the increased susceptibility of RL 2/2 mice to MHV-JHM infection. doi = 10.1371/journal.ppat.1000602 id = cord-023394-ptfjxpo6 author = Isa, A. title = Mapping of the Ex Vivo Cellular Immune Response Against the Complete Human Parvovirus B19 Genome During Acute Infection date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = We demonstrate that Cw6 þ psoriasis patients had significant CD8 þ T-cell IFN-g responses to peptides from K17 and M6 protein selected on the basis of sequence homology and predicted HLA-Cw*0602 binding.

Since NK precursors and other ILC populations in secondary lymphoid tissues express varying levels of this integrin, it may be possible that an NK-DC interaction is a requirement for immature NK cells to be signaled to home to mucosal sites. During mucosal infections of humans and mice, NK cells are recruited to sites of infection and play an important role in immune defense [6, 48] . Therefore the cytokine milieu present in the different mucosal tissues in addition to activating signals stimulated that by diverse pathogens help NK cells respond to infection. NK cells in humans are also important for innate control of gut mucosal infections. During infection, resident mucosal tissue NK cells respond primarily through IFN production, which contributes directly to early control of pathogens. doi = 10.1155/2014/413982 id = cord-003315-r1wkx0ml author = Jacobs, Sophie title = Species Specificity of Type III Interferon Activity and Development of a Sensitive Luciferase-Based Bioassay for Quantitation of Mouse Interferon-λ date = 2018-11-01 keywords = ELISA; Fawa; IFN; mouse summary = doi = 10.1089/jir.2018.0066 id = cord-266679-gs1k7263 author = Jacques, Alexandre title = A synergistic interferon-γ production is induced by mouse hepatitis virus in interleukin-12 (IL-12)/IL-18-activated natural killer cells and modulated by carcinoembryonic antigen-related cell adhesion molecules (CEACAM) 1a receptor date = 2009-09-01 keywords = IFN; IL-12; l2-mhv3 summary = doi = 10.1111/j.1365-2567.2008.03030.x id = cord-303893-47lxq8pi author = Jalkanen, Juho title = Interferon beta-1a for COVID-19: critical importance of the administration route date = 2020-06-12 keywords = IFN; beta summary = Interferon beta-1a for COVID-19: critical importance of the administration route Juho Jalkanen 1 , Maija Hollmén 2 and Sirpa Jalkanen 2* Type I interferons, especially IFN-beta, have been appointed as potential leading therapeutics to tackle severe COVID-19 and are currently being evaluated in REMAP-CAP and the WHO''s Solidarity Trial. We wish to highlight the differences of these two treatment methods and also other crucial aspects of IFN-beta treatment for COVID-19 and acute respiratory distress syndrome (ARDS). Nonetheless, the purpose of i.v. administered IFN-beta for the treatment of COVID-19 and ARDS is to maximise bioavailability of the drug at the lung vasculature, as well as other vascular beds. There are a limited number of direct studies on the timing of immunomodulatory treatments such as IFN-beta, but given our basic understanding of human biology and viral defence, we suggest that IFN-beta should be given early to COVID-19 patients. doi = 10.1186/s13054-020-03048-5 id = cord-332688-xqt2aw96 author = Jalkanen, Juho title = Glucocorticoids inhibit type I IFN beta signaling and the upregulation of CD73 in human lung date = 2020-05-19 keywords = CD73; IFN summary = doi = 10.1007/s00134-020-06086-3 id = cord-299299-ov6bf1ff author = Janowicz, Anna title = Multiple Genome Segments Determine Virulence of Bluetongue Virus Serotype 8 date = 2015-03-11 keywords = BTV8; IFN; vp2 summary = Replication of BTV8(H) was relatively poor in interferon (IFN)-competent primary ovine endothelial cells compared to replication of BTV8(L), and this phenotype was determined by several viral genomic segments, including Seg4 and Seg9.

Both viruses replicated very efficiently in IFN-deficient CPT-Tert cells, but BTV8 H reached titers approximately 100-fold higher than its parental virus (Fig. 1A) . The data obtained so far indicate that BTV8 H had accumulated mutations that affected virus replication in IFN-competent cells and resulted in attenuation in vivo both in IFNAR Ϫ/Ϫ mice and in sheep. doi = 10.1128/jvi.00395-15 id = cord-273122-w9hemznv author = Jans, Jop title = Actin- and clathrin-dependent mechanisms regulate interferon gamma release after stimulation of human immune cells with respiratory syncytial virus date = 2016-03-22 keywords = IFN; RSV summary = doi = 10.1186/s12985-016-0506-6 id = cord-334510-37g8zxne author = Jartti, T. title = Distinct regulation of tonsillar immune response in virus infection date = 2014-03-29 keywords = IFN; IL-37; Tbet summary = OBJECTIVE: To study intratonsillar/nasopharyngeal virus detections and in vivo expressions of T‐cell‐ and innate immune response‐specific cytokines, transcription factors, and type I/II/III interferons in human tonsils.

In RIg-I-deficient cells, influenza virus fails to elicit the expression of IFNβ and of many ISgs, including key antiviral mediators such as IRF3, STAT1 (signal transducer and activator of transcription 1), IFIT1 (IFN-induced protein with tetratricopeptide repeats 1; also known as ISg56) and ISg54 (also known as IFIT2). Although these studies have provided considerable information regarding the genes activated downstream of TlR activation, it will be advantageous to extend genomic analyses in the context of viral infection using cells lacking the expression of specific TlRs. The ability of a virus to establish an infection depends, at least to some extent, on its ability to block the host innate immune response or to modulate the activity of antiviral effector proteins. doi = 10.1038/nri2377 id = cord-000125-uvf5qzfd author = Kenworthy, Rachael title = Short-hairpin RNAs delivered by lentiviral vector transduction trigger RIG-I-mediated IFN activation date = 2009-09-03 keywords = B971; IFN; RNA; figure; rig summary = The interaction between a PAMP and a PRR triggers activation of the interferon (IFN) pathway in mammalian cells, which significantly changes the gene-expression profile in the cells and contributes to the well-documented off-target effect of RNAi. IFN induction is especially problematic in antiviral studies employing RNAi, where the antiviral effect of IFN must be distinguished from that of RNAi. Typical IFN-inducing structure patterns include dsRNA of certain length, single-stranded RNA (ssRNA) containing 5 0 -triphosphates (5 0 -ppp), the dsRNA analogue polyinosinic-polycytidylic acid (poly I:C), and certain dsDNA molecules. Mammalian expression plasmids encoding each of these proteins, as well as the dominant negative (DN) mutants of RIG-I and MDA5, were transfected into 293FT cells with shRNAs and an IFN-b promoter reporter construct. doi = 10.1093/nar/gkp714 id = cord-288238-36hiiw91 author = Keshavarz, Mohsen title = Metabolic host response and therapeutic approaches to influenza infection date = 2020-03-05 keywords = ATP; IFN; ROS; infection; influenza; virus summary = It is also reported that influenza infection significantly increases ROS production by inducing Nox4, and the proliferation of this virus in lung epithelial cells is dependent on redox-sensitive pathways activated by Nox4-derived ROS [16] . IFN can also exert its function on metabolic changes by producing several mediators including indoleamine-2,3-dioxygenase (IDO) and nitric oxide (NO), both of which appear to have either an inducible or an inhibitory role in viral replication [33] . In addition, increased temperature of cells during infection (which could be the result of virus replication and fever) causes heat stress which in turn can considerably downregulate carnitine palmitoyltransferase II (CPT II) activity and reduce the β-oxidation and ATP levels in fibroblasts of influenza-associated encephalopathy patients and healthy volunteers [110] . Through enhancing the activity of the mTORC1 complex, the influenza virus strengthens several metabolic pathways, including glycolysis, glutaminolysis, pentose phosphate, and fatty acid synthesis, to provide more ATP and structural materials for viral replication. doi = 10.1186/s11658-020-00211-2 id = cord-253862-jl1zhg13 author = Khalaf, Khalil title = SARS-CoV-2: Pathogenesis, and Advancements in Diagnostics and Treatment date = 2020-10-06 keywords = ACE-2; COVID-19; CoV-2; IFN; RNA; SARS; cell; patient summary = Although this novel virus is less severe than the first SARS-CoV outbreak, human-to-human transmission remains very high and the number of cases continues to rise exponentially in major urban areas, highlighting the urgent need to develop new containment, diagnostic, and treatment protocols. In the case of SARS-CoV-2, viral evasion of the innate immune system leads to an increase in cytokine production and late CD4+/CD8+ response, which then leads to pathogenic inflammation in patients with high viral loads. (ChiCTR2000029308), involving severe SARS-CoV-2 cases, compared lopinavir/ritonavir treatment with standard care alone, and they showed that the antivirals yielded no clinical benefits. In an open-label control study conducted by Cai et al., the antiviral activity of favipiravir + IFN-α was compared to that of lopinavir/ritonavir + IFN-α in patients with confirmed SARS-CoV-2 infection. doi = 10.3389/fimmu.2020.570927 id = cord-328252-dk54w8z9 author = Kikkert, Marjolein title = Innate Immune Evasion by Human Respiratory RNA Viruses date = 2019-10-14 keywords = IFN; RNA; immune; innate; rig; virus summary = Whether PA-X also degrades viral dsRNA species to prevent recognition by cytosolic RNA sensors is not entirely clear, but mutant viruses in which this PA-X protein was expressed in significantly lower amounts elicited higher levels of innate immune response; for example, IFN-beta production was much higher in these infections [71] . This indeed suggests that PA-X, besides having a role in the degradation of cellular mRNAs, may also degrade viral RNA to prevent recognition by innate immune sensors and activation of innate immune responses, similar to what was shown for the CoVs. To my knowledge, an endoribonuclease has not been identified in the RSV genome, so this virus may use alternative innate immune evasion strategies, as discussed elsewhere in this review. [91] suggested that RSV specifically targets mRNA encoding surfactant protein A, an innate immune factor with an important role in the epithelial tissue of the lung, which directly binds to virus particles to cause their destruction by host defense mechanisms. doi = 10.1159/000503030 id = cord-002021-67ao8chx author = Kim, Seong Bum title = Blockage of indoleamine 2,3-dioxygenase regulates Japanese encephalitis via enhancement of type I/II IFN innate and adaptive T-cell responses date = 2016-04-18 keywords = BL/6; CD4; CNS; IDO; IFN; JEV summary = doi = 10.1186/s12974-016-0551-5 id = cord-290744-m0vpizuh author = Kindler, E. title = Interaction of SARS and MERS Coronaviruses with the Antiviral Interferon Response date = 2016-09-09 keywords = IFN; MERS; RNA; SARS summary = doi = 10.1016/bs.aivir.2016.08.006 id = cord-343221-e29of29o author = Kindler, Eveline title = Early endonuclease-mediated evasion of RNA sensing ensures efficient coronavirus replication date = 2017-02-03 keywords = A59; Fig; H277A; IFN; MHV; RNA summary = Specifically, we show that genetically engineered mutants of mouse hepatitis virus (MHV) and human coronavirus 229E (HCoV-229E), respectively, that encode an EndoU active-site substitution known to abolish nucleolytic activity, were severely attenuated and elicited an immediate and simultaneous activation of host cell dsRNA sensors. The severe attenuation of MHV H277A and HCoV-229E H250A replication in wild-type murine and human macrophages, respectively, precluded the use of primary macrophages to assess the sensitivity of EndoU-deficient coronaviruses to IFN-I pre-treatment. Our data suggest that direct restriction of replication of EndoU-deficient coronaviruses is mediated by RNase L-mediated RNA degradation and inhibition of host cell translation through activation of PKR. Notably, also in this case Xrn1 is required to further process the de-capped mRNAs. Our data show that early during coronavirus infection the EndoU activity conceptually fulfils the same task, namely the removal of dsRNA that would otherwise trigger host cell dsRNA responses, such as IFN-β expression and activation of PKR and OAS/RNase L. doi = 10.1371/journal.ppat.1006195 id = cord-003614-63rzzos3 author = Klotz, Daniela title = Interferon-Stimulated Genes—Mediators of the Innate Immune Response during Canine Distemper Virus Infection date = 2019-04-01 keywords = CDV; IFN; IRF3; IRF7; PKR; stat1 summary = doi = 10.3390/ijms20071620 id = cord-023410-eblcf902 author = Kollgaard, T.

Furthermore, we demonstrated the clinical utility of the iROAD assay by detecting respiratory viral RNAs extracted from the 63 nasopharyngeal samples with either IFN-A/B or HCoV-OC43/229E or RSV-A/B. Subsequently, the iROAD assay detected the respiratory viral targets from the clinical sample by measuring the resonance wavelength shift within 15-20 min (Fig. 1) . In case of the iROAD assay with label-free and real-time capabilities, the wavelength shift was sequentially increased based on the concentrations (2.5×10 1 to 10 5 copies/reaction) of IFN-B within 20 min, as compared to the negative control. In the case of the real-time RT-PCR assay, the fluorescent SYBR Green signal was observed in RNA samples diluted up to 2.5×10 2 copies/reaction and showed good linearity (R 2 =0.9795) for different concentrations of the target (Fig. 3C ). doi = 10.1016/j.bios.2016.11.051 id = cord-001515-x11t9pbv author = Kosinska, Anna D. title = Therapeutic vaccination and immunomodulation in the treatment of chronic hepatitis B: preclinical studies in the woodchuck date = 2014-12-23 keywords = HBV; IFN; WHV summary = Several innovative approaches combining antiviral treatments using nucleos(t)ide analogues, with prime-boost vaccination using DNA vaccines, new hepadnaviral antigens or recombinant adenoviral vectors were tested in the woodchuck model.

Signal transducers and activators of transcription (STATs) are a family of transcription factors that play crucial roles in regulating a number of diverse biological functions including cell proliferation, differentiation, apoptosis, inflammatory response, immunity, and angiogenesis [1] . The seemingly contradictory roles of STAT3 in viral infections raise a number of interesting questions: "what factors determine the switch between pro-and anti-inflammatory functions of STAT3?," "how are viruses able to exploit STAT3 signalling for their gene replication?," and "does STAT3 either negatively or positively regulate type 1 IFN response depending on the virus type involved?" Further in depth studies to dissect the role of STAT3 in viral infections could provide valuable insights into viral pathogenesis and development of novel antiviral therapies.

In this study, we report that infection of FrhK4 cells with the HAV cp strain HM175/18f results in the degradation of ribosomal RNA (rRNA) and the reduction of several cellular mRNAs including β-actin and GAPDH. Degradation of rRNA is a feature of virus infection in interferon (IFN) treated cells and is believed to be due to the availability of double stranded RNA (dsRNA) during replication or transcription of the viral genome, resulting in the activation of the RNase L pathway [58, 59] . While the role of a viral protein in the activation of 2-5A/RNase L pathway in 18f or CBV1 infected FrhK4 cells cannot be ruled out, previous reports with EMC virus and the studies involving dsRNA clearly suggests a similar mechanism of rRNA degradation reported here. doi = 10.1007/s00705-003-0110-0 id = cord-290396-cy4y8vnt author = Kumar, Matam Vijay title = Innate immunity in the retina: Toll-like receptor (TLR) signaling in human retinal pigment epithelial cells date = 2004-07-01 keywords = IFN; TLR; rpe summary = title: Innate immunity in the retina: Toll-like receptor (TLR) signaling in human retinal pigment epithelial cells We evaluated the expression and function of TLRs in human retinal pigment epithelial (RPE) cells. The presence of TLRs on RPE cells and the resultant TLR signaling in RPE cells suggest that these molecules may play an important role in innate and adaptive immune responses within the retina. Our data suggest that the binding of poly I:C, an analog of dsRNA, to TLR 3 on human RPE cells resulted in the production of IFN-h and other cytokines, chemokines, and adhesion molecules. Total RNA prepared from confluent monolayers of human RPE cells and from suspension cultures of U937 was used to evaluate the constitutive expression of TLR mRNA. To study the effects of TLR activators, human RPE cells were washed with serum-free media (SFM) and incubated in SFM for 12 h in the presence of poly I:C (100 Ag/ml ), LPS (5 Ag/ml), or IFN-g (100 U/ml). doi = 10.1016/j.jneuroim.2004.04.018 id = cord-001901-2s6hpakk author = Kwok, Hoi-Hin title = Anti-inflammatory effects of indirubin derivatives on influenza A virus-infected human pulmonary microvascular endothelial cells date = 2016-01-06 keywords = Fig; IFN; JNK; STAT3 summary = doi = 10.1038/srep18941 id = cord-256187-ofp7tupv author = Kühl, A. title = How Ebola Virus Counters the Interferon System date = 2012-09-07 keywords = EBOV; Ebola; IFN; VP35 summary = doi = 10.1111/j.1863-2378.2012.01454.x id = cord-001542-f089bs8r author = Lai, Kang Yiu title = Human Ebola virus infection in West Africa: a review of available therapeutic agents that target different steps of the life cycle of Ebola virus date = 2014-11-28 keywords = EBOV; Ebola; GP1,2; IFN; RNA; cell; infection; virus summary = doi = 10.1186/2049-9957-3-43 id = cord-290593-vhmi2559 author = Lannes, Nils title = Interplay of foot-and-mouth disease virus, antibodies and plasmacytoid dendritic cells: virus opsonization under non-neutralizing conditions results in enhanced interferon-alpha responses date = 2012-08-30 keywords = FMDV; IFN; PBMC summary = title: Interplay of foot-and-mouth disease virus, antibodies and plasmacytoid dendritic cells: virus opsonization under non-neutralizing conditions results in enhanced interferon-alpha responses Vaccine-induced immune protection correlates with the presence of high levels of neutralizing antibodies but also opsonising antibodies have been proposed as an important mechanism of the immune response contributing to virus clearance by macrophages and leading to the production of type-I interferon (IFN) by plasmacytoid dendritic cells (pDC). The present study demonstrates that the opsonising antibody titres mediating enhanced IFN-α responses in pDC were similar to neutralizing titres, when antigenically related viruses from the same serotype were employed. Considering the possible importance of opsonising antibodies and pDC in the protection against FMDV, the main aim of this study was to characterize the relationship between neutralizing and opsonising activities of polyclonal sera from immunized pigs.

Compared with a recently published microarray analysis of type I and type III IFN responses in PHH, which used similar statistical thresholds but substantially higher IFNλ concentrations than our study (1000 ng ml − 1 ), 11 our RNA-seq data provide a more complete estimate of the IFN response (87 versus 50 genes significantly regulated by IFNλ3). doi = 10.1038/gene.2015.23 id = cord-023445-c4tqioz1 author = Lauridsen, C. title = Supplementation of Vitamin C to Weaner Diets Increases IgM Concentration and Improves the Biological Activity of Vitamin E in Alveolar Macrophages date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423u.x id = cord-332071-bqvn3ceq author = Lee, Jeong Seok title = Immunophenotyping of COVID-19 and influenza highlights the role of type I interferons in development of severe COVID-19 date = 2020-07-10 keywords = Fig; IFN; SARS; TNF; covid-19 summary = doi = 10.1126/sciimmunol.abd1554 id = cord-320338-jv76j6wx author = Lee, Kyungjin title = Gemcitabine, a broad-spectrum antiviral drug, suppresses enterovirus infections through innate immunity induced by the inhibition of pyrimidine biosynthesis and nucleotide depletion date = 2017-12-15 keywords = IFN; figure; gemcitabine summary = In this study, we found that the addition of exogenous cytidine, uridine and uridine mono-phosphate (UMP) effectively reversed the antiviral activity of gemcitabine in enterovirus-infected as well as enteroviral replicon-harboring cells, demonstrating gemcitabine''s targeting of the salvage pathway. At first, in order to test if the anti-enteroviral activity of gemcitabine is related with the inhibition of pyrimidine biosynthesis, HeLa cells were infected with CVB3 and simultaneously treated with excessive 4 nucleosides (adenosine, guanosine, uridine and cytidine) in the presence of various doses of gemcitabine for 8 hours.

PRRSV isolates were differentially sensitive to porcine recombinant IFN-α (rIFN-α) and varied in their ability to induce IFN-α in porcine alveolar macrophages (PAM) cultures as measured by a porcine IFN-α specific ELISA on cell culture supernatants. In this study, North American field isolates of PRRSV were evaluated with respect to induction, sensitivity and suppression of an in vitro type I IFN response. UV-inactivated PRRSV stocks were tested to determine whether virus binding to the cells is responsible for enhanced IFN-a production by polyI:C in cells infected with isolate 3 (Fig. 6) .

However, we used guinea pigs to evaluate the ability of the ssRNA adjuvant to enhance neutralizing antibody production and cell-mediated immune response in VZV LAV. Based on all results, we showed the potential of ssRNA adjuvants to compensate for the limitations of protein-based vaccines with respect to low T-cell activity and short-term responses, as well as to increase the neutralizing antibody in LAV for preventing VZV-induced disease. 41 Here, the ssRNA adjuvant-induced humoral and balanced Th1/Th2 immune responses even though its antibody and cytokine induction levels in the VZV gE protein subunit vaccine were lower than those for AddaVax. Nevertheless, the mode of action of AddaVax has not yet been elucidated. Moreover, the ssRNA derived from CrPV IGR IRES encoding the gE gene, which could express gE in transfected cells, can effectively function as a vaccine adjuvant in a protein-based subunit vaccine by activating humoral and cell-mediated immune responses. doi = 10.1002/iid3.297 id = cord-333286-lr32e0w4 author = Lehtoranta, Liisa title = Role of Probiotics in Stimulating the Immune System in Viral Respiratory Tract Infections: A Narrative Review date = 2020-10-16 keywords = IFN; infection; probiotic; respiratory summary = doi = 10.3390/nu12103163 id = cord-310396-jitao9k0 author = Lei, Yu title = MAVS-Mediated Apoptosis and Its Inhibition by Viral Proteins date = 2009-03-07 keywords = Fig; IFN; MAVS; SARS; cell summary = doi = 10.1371/journal.pone.0005466 id = cord-286328-ap0wfjhq author = Lewis, Toby C. title = Nasal cytokine responses to natural colds in asthmatic children date = 2012-11-26 keywords = IFN; asthma; infection; viral summary = CONCLUSIONS & CLINICAL RELEVANCE: We conclude that, in children with asthma, naturally-occurring viral infections apparently induce a robust innate immune response including expression of specific chemokines, IFNs and IFN-responsive genes. To further examine the innate immune response to viral infection in children with asthma, we measured nasal aspirate cytokine levels in 16 asthmatic children before and after upper respiratory tract infections. We also examined the effects of upper respiratory tract infection on mRNA levels of selected markers of viral infection, including IFNs. Finally, we evaluated a new method of virus detection using a single polymerase chain reaction-ligation detection reaction (PCR-LDR) multiplex assay. We performed home measurements of respiratory symptoms and collected nasal secretions (for detection of viral RNA by PCR and host biomarkers by PCR and ELISA) on 3 days during a week when children were healthy (not reporting upper respiratory tract infection or asthma symptoms), and again during a week when they experienced cold or flu-like symptoms. doi = 10.1111/cea.12005 id = cord-302401-oyhzn2kc author = Li, Chenxi title = Duck karyopherin α4 (duKPNA4) is involved in type I interferon expression and the antiviral response against Japanese encephalitis virus date = 2019-11-05 keywords = Fig; IFN; JEV; KPNA4 summary = doi = 10.1016/j.dci.2019.103535 id = cord-278018-3qemb0x3 author = Li, Li title = Identification of M.tuberculosis-Specific Th1 Cells Expressing CD69 Generated in vivo in Pleural Fluid Cells from Patients with Tuberculous Pleurisy date = 2011-08-22 keywords = CD4; CD69; IFN summary = doi = 10.1371/journal.pone.0023700 id = cord-254192-86ksgl5t author = Li, Liang title = IFN-Lambda 3 Mediates Antiviral Protection Against Porcine Epidemic Diarrhea Virus by Inducing a Distinct Antiviral Transcript Profile in Porcine Intestinal Epithelia date = 2019-10-17 keywords = IFN; IPEC; PEDV; RNA summary = doi = 10.3389/fimmu.2019.02394 id = cord-309428-qkjjxr6p author = Li, Liwei title = Host miR-26a suppresses replication of porcine reproductive and respiratory syndrome virus by upregulating type I interferons date = 2015-01-02 keywords = Fig; IFN; PRRSV summary = MicroRNAs (miRNAs) play important roles in viral infections, especially by modulating the expression of cellular factors essential to viral replication or the host innate immune response to infection. To identify host miRNAs important to controlling porcine reproductive and respiratory syndrome virus (PRRSV) infection, we screened 15 miRNAs that were previously implicated in innate immunity or antiviral functions. Luciferase reporters showed that miR-26a does not target the PRRSV genome directly but instead affects the expression of type I interferon and the IFN-stimulated genes MX1 and ISG15 during PRRSV infection. We found that miR-26a does not target the PRRSV genome directly, but rather affects the expression of type I interferon and the IFN-stimulated genes MX1 and ISG15 during PRRSV infection.

Porcine epidemic diarrhea virus (PEDV) is the etiological agent of porcine epidemic diarrhea (PED) that causes an acute and highly contagious enteric disease of swine characterized by vomiting, diarrhea, dehydration, and anorexia in pigs of all ages, especially resulting in severe diarrhea and high mortality rate in piglets. Nsp3 is the largest nsp protein, containing two papain-like protease (PLP1 and PLP2) domains, of which PEDV PLP2 acts as a viral deubiquitinase (DUB), to negatively regulate type I IFN signaling [80] . The evasive strategies utilized by PEDV are classified into four major types: (1) inhibition of RLRs-mediated IFN production pathways, (2) inhibition of the activation of transcription factors responsible for IFN induction, (3) disruption of the signal cascades induced by IFN, and (4) hiding its viral RNA to avoid the exposure of viral RNA to immune sensors. doi = 10.3390/pathogens9050367 id = cord-276166-b1e0bbrp author = Li, Shi-fang title = Interferon-omega: Current status in clinical applications date = 2017-10-12 keywords = IFN; activity; cat; feline; interferon summary = Previous studies showed that glycosylated IFN-ω + ribavirin (RBV) had a synergistic effect in terms of its antiviral activity in hepatitis C virus (HCV)-infected patients [43] .

To further characterize the role of IFN-λ in RABV infection in the mouse model, recombinant RABVs (rRABVs) expressing murine IFN-λ2 or IFN-λ3, designated as rB2c-IFNλ2 and rB2c-IFNλ3 respectively, were constructed as shown in Figure 2A , and rescued as described previously [27] . To further investigate whether IFN-λ restricts RABV infection in vivo, groups of five-week-old female BALB/c mice were mock-infected with DMEM or inoculated with B2c, rB2c-IFNλ2, or rB2c-IFNλ3 by different routes.

Epithelial cells are key regulators of the innate immune response against viral infections (Garofalo and Haeberle, 2000) , producing a number of inflammatory mediators in response to RSV infection. In summary, in RSV lower respiratory tract infections, cytotoxic CD8ϩ T-cells are involved in viral clearance while the humoral response is required for the protection against reinfection. The innate immune defense to viral respiratory tract infections consists of the mucosal layer, type 1 interferons, activated phagocytes, and NK-cells. A key question is whether the association with the development of asthma is merely an expression of increased susceptibility to both asthma and RSV-induced lower respiratory tract infections or whether true causality is involved. doi = 10.1007/0-387-25342-4_4 id = cord-003130-p2h8p5bm author = Lindqvist, Richard title = Tick-Borne Flaviviruses and the Type I Interferon Response date = 2018-06-21 keywords = IFN; LGTV; RNA; TBEV; tick; virus summary = doi = 10.3390/v10070340 id = cord-348684-xbxwpmxq author = Liu, Bao-qin title = Ubiquitination modification: critical regulation of IRF family stability and activity date = 2020-10-30 keywords = IFN; IRF3; IRF7 summary = Interferon regulatory factors (IRFs) play pivotal and critical roles in innate and adaptive immune responses; thus, precise and stringent regulation of the stability and activation of IRFs in physiological processes is necessary. Knowledge of how these proteins function and interact with IRFs may provide a better understanding of the regulation of IRFs in immune responses or other biological processes and exciting targets for the development of drugs aimed at regulating the functions of specific E3 ligases or DUBs. Ubiquitination is a type of reversible cellular protein PTM. Furthermore, K63-linked polyubiquitination and monoubiquitination, the second most common type of ubiquitin linkage, mediate proteasome-independent effects, which play an important role in activating many components of different signaling pathways and participate in many biological processes (Ning et al., 2011) . c-Cbl, a member of the Cbl (Casitas B-lineage lymphoma) family, negatively regulates IRF3 protein stability by interacting with the C-terminal domain of IRF3 via its TKB (tyrosine kinase binding) domain and promotes K48-linked polyubiquitination-dependent proteasomal degradation of IRF3 (Zhao et al., 2016) . doi = 10.1007/s11427-020-1796-0 id = cord-007654-lchdm4xr author = Liu, Yang title = Flavivirus infection up-regulates the expression of class I and class II major histocompatibility antigens on and enhances T cell recognition of astrocytes in vitro date = 2002-12-11 keywords = IFN; MHC; WNV summary = doi = 10.1016/0165-5728(89)90171-9 id = cord-310469-v4p01rze author = Livonesi, Márcia Cristina title = In vitro and in vivo studies of the Interferon-alpha action on distinct Orthobunyavirus date = 2007-02-28 keywords = CARV; GROV; IFN-; OROV summary = Thus, in an effort to characterize antiviral agents that could attenuate infections caused by OROV, CARV, GMAV, GROV and TCMV, we tested the in vitro and in vivo actions of IFN-␣ on these viruses. However, treatment of CARV-, GMAV-or TCMV-infected mice with IFN-␣A did not result in an increase in survival or prolongation of the mean time to death and did not prevent virus replication in the brain of animals (Table 2 and Fig. 3, respectively) . Treatment with IFN-␣A initiated 24 h after mice infection by GROV was unable to inhibit either the death of animals or the viral replication in the brain (Table 3 and Fig. 5 , respectively). In vitro and in vivo results showed that IFN-␣ was able to prevent viral replication in a limited manner, exerting antiviral effect only when administrated early and in high doses, suggesting that OROV, CARV, GMAV, GROV and TCMV present some escape mechanism from antiviral actions of the IFN-␣. doi = 10.1016/j.antiviral.2007.01.158 id = cord-335384-co2fgz26 author = Lobo‐Silva, Diogo title = Interferon‐β regulates the production of IL‐10 by toll‐like receptor‐activated microglia date = 2017-06-15 keywords = IFN; IL-10; TLR2; TLR3; figure summary = These differential responses were not dependent on the dose of agonist used to stimulate microglia, as increasing the doses of TLR ligands did not result in enhanced secretion of IL-10, nor of TNF (Supporting Information, Figure 1 ).

In non-specialized epithelial cells as well as a subset of specialized immune cells that are susceptible to MERS-CoV infection, 16, 18, 27 type I IFN production is an important part of the host innate immune response and is initiated by ubiquitously expressed cytoplasmic viral sensors in the retinoic acid-inducible gene-I (RIG-I)-like receptor (RLR) family in response to the detection of viral pathogen-associated molecular patterns such as double-stranded RNA (dsRNA).

Thus, the survival strategy of BVDV consists of being non-cytopathogenic and producing less dsRNA than its cp counterpart, and expressing the IFN antagonists N pro as the first protein in order to reduce or even avoid IFN production in infected cells and E rns to degrade immunostimulatory viral RNA before they might activate the host''s PRRs. Notably, both pestiviral IFN antagonists are not only required to constantly maintain innate immunotolerance during persistent infections, but they also play an important role in acute infections [25] . doi = 10.1016/j.cytogfr.2016.03.003 id = cord-004400-li1sc47z author = Ma, Jingjiao title = Acetylation at K108 of the NS1 protein is important for the replication and virulence of influenza virus date = 2020-02-24 keywords = IFN; WSN; ns1; protein summary = doi = 10.1186/s13567-020-00747-3 id = cord-002079-jne14jqf author = MacParland, Sonya A. title = Lipopolysaccharide and Tumor Necrosis Factor Alpha Inhibit Interferon Signaling in Hepatocytes by Increasing Ubiquitin-Like Protease 18 (USP18) Expression date = 2016-05-27 keywords = IFN-; LPS; TNF-; usp18 summary = doi = 10.1128/jvi.02557-15 id = cord-016499-5iqpl23p author = Mackay, Ian M. title = Rhinoviruses date = 2014-02-27 keywords = ARI; HRSV; HRV; IFN; PCR; RNA; human; infection; respiratory; rhinovirus; viral; virus summary = doi = 10.1007/978-1-4899-7448-8_29 id = cord-310444-02dsqbeg author = Mahlakoiv, T. title = P136 Combined action of type I and type III IFN restricts initial replication of SARS-coronavirus in the lung but fails to inhibit systemic virus spread date = 2012-09-30 keywords = GSK3; IFN summary = Conclusion Our data suggest that the failure of STAT1-deficient mice to efficiently control initial SARS-CoV replication in the lung is due to impaired type I and type III IFN signaling, whereas the failure to control subsequent systemic viral spread is due to unrelated defects in STAT1-deficient mice. The type III interferons are especially important in pulmonary infection, produced in response to viral infection and bacterial PAMPs. IFN-k is activated by and induces NF-jB signaling and promotes expression of Th1 cytokines. Consistent with the expected participation of IFN-k in NF-jB signaling, we measured decreased expression of KC, TNF and GM-CSF and increased IL-10 in the IL-28RÀ/ -BAL (P < 0.05), although there were no significant differences in the populations of immune cells (neutrophils, DC, macrophages) recruited to the airways of the wild type or IL-28RÀ/À mice. Ligation of immunoreceptor tyrosine-based activation motif (ITAM)associated receptors in macrophages can initiate potent induction of negative regulators, including anti-inflammatory cytokine IL-10, signaling inhibitors SOCS3, ABIN3, A20 and transcriptional repressor Hes1 [1] . doi = 10.1016/j.cyto.2012.06.228 id = cord-308298-5ntdb8yf author = Mair, Kerstin H title = Porcine CD8α(dim/-)NKp46(high) NK cells are in a highly activated state date = 2013-03-01 keywords = CD27; CD3; IFN; cell summary = Functional analyses revealed that splenic NKp46(high) NK cells produced much higher levels of Interferon-γ and Tumor Necrosis Factor-α upon stimulation with cytokines or phorbol-12-myristate-13-acetate/Ionomycin compared to the other two subsets.

Splenic NKp46 high NK cells showed an overall higher expression of this receptor compared to NKp46and NKp46 + NK-cell subsets from both spleen and blood. Splenic NKp46 high NK cells showed highly elevated expression of this activating receptor compared to the other two NKp46-defined subsets in spleen as well as in blood in all animals analysed, which could be demonstrated on protein as well as on mRNA level. doi = 10.1186/1297-9716-44-13 id = cord-312001-8p7scli8 author = Majzoub, Karim title = The Innate Antiviral Response in Animals: An Evolutionary Perspective from Flagellates to Humans date = 2019-08-16 keywords = IFN; MAVS; MDA5; RNA; dna; rig; sting summary = Consequently, animal cells have evolved devoted pathways which (1) sense and recognize pathogen-associated molecular patterns (PAMPs) and, more particularly, virus-associated molecular signatures; (2) initiate signaling cascades stemming from the site of detection, translocating the information to the nucleus; and (3) induce a transcriptional program that confers an antiviral state to the host ( Figure 1 ). While the cytosolic recognition of viral RNA is almost exclusively mediated by RLRs, several proteins have been proposed to play a role in DNA sensing and triggering innate immune responses, such as the DNA-dependent activator of IFN-regulatory factors (DAI), DDX41, RNA polymerase III, IFI16 and DNA-PK [62] [63] [64] [65] [66] [67] . Although the pathway leading to the transcriptional activation of Vago is still poorly understood in insects, these studies established that DExD/H-box helicase containing proteins, like Dicer and RLRs, may represent an evolutionarily conserved set of viral nucleic acid sensors that direct antiviral responses in animals [159] . doi = 10.3390/v11080758 id = cord-333650-4towah1t author = Malmo, Jostein title = Cytokine Profiles in Human Metapneumovirus Infected Children: Identification of Genes Involved in the Antiviral Response and Pathogenesis date = 2016-05-12 keywords = IFN; TNF summary = Overall, our data point to cytokines, particularly inflammasome-associated, that might be important in hMPV mediated lung disease and the antiviral response in children with severe infection. To determine the presence of antiviral cytokines in children infected with hMPV and controls, we initially investigated the expression of type I, II and III IFNs. Fig 1A shows that only A2 infected children had slightly elevated mRNA levels of the type I IFN-β compared to the controls. Fig 2 shows the mRNA expression of A) IκBα, a repressor gene induced by NF-κB activation [19] , B) IL-1β, C) IL-18 and D) NLRP3 in hMPV infected children and controls.

It is likely that differences in evolutionary history of pathogen exposure between bats and humans have led to distinct adaptations in anti-viral immune responses and the ability to tolerate certain infections without disease while being susceptible to others. We summarize this work below, but comparisons of observations made across species suggest that although a number of species appear to be capable of avoiding the pathological effects of RNA virus infection, each bat species may have achieved this through distinct pathways, possibly involving changes to both increase pathogen replication control and to mitigate any immunopathology through decreased inflammatory responses and hence increased disease tolerance. doi = 10.3389/fimmu.2018.02112 id = cord-263200-ntq1f4ix author = Mao, He-Ting title = HACE1 Negatively Regulates Virus-Triggered Type I IFN Signaling by Impeding the Formation of the MAVS-TRAF3 Complex date = 2016-05-21 keywords = IFN; MAVS; hace1 summary = To initiate an effective antiviral response, RNA viruses are recognized by pattern recognition receptors (PRRs), such as Toll-like receptors (TLRs) and RIG-I-like receptors (RLRs), and then trigger multiple signaling pathways to promote the production of proinflammatory cytokines, including type I IFNs [1] [2] [3] [4] . In this study, we demonstrate for the first time that HACE1 contributes to negative regulation of the virus-induced type I IFN signaling via disrupting the MAVS-TRAF3 complex. HACE1 suppressed virus-induced type I IFN signaling independently of its ubiquitin E3 ligase activity. By a small-scale screening of unknown ubiquitin E3 ligases in the regulation of virus-induced type I IFN signaling by the dual-luciferase reporter, we identified HACE1 as a potential negative regulator in this pathway.

Natural Killer (NK) cells are a key component of the innate immune system and are critical in the response to many viral infections in humans and animal models (1) (2) (3) . Altogether these studies show that during acute CoV infection, inflammatory monocyte-macrophages and neutrophils accumulate in the lungs and produce cytokines and chemokines that induce the activation and migration of lymphocytes, including NK cells, to the lungs, where they could be one of the main producers of IFN-γ (148). Studies have reported that patients infected with SARS-CoV-2 have lower levels of circulating NK cells and these express a greater level of inhibitory receptors (e.g., NKG2A) while producing less IFN-γ (127, 129, 130) . doi = 10.3389/fimmu.2020.01512 id = cord-337458-dc90ecfe author = Markwalter, Christine F. title = Inorganic Complexes and Metal-Based Nanomaterials for Infectious Disease Diagnostics date = 2018-12-04 keywords = Amplification; Assay; Based; Detection; Diagnosis; ECL; Flow; HIV; HRP2; IFN; IMAC; Immunoassay; Lateral; Magnetic; Malaria; POC; Rapid; figure; nanoparticle; sensitive; test summary = In this review, we define the components of a diagnostic to include: (1) the target biomarker, an endogenous indicator of a disease state, which is most often a pathogen or host protein, carbohydrate, or nucleic acid sequence, (2) sample preparation, which allows for biomarker isolation, purification, and/or concentration from complex biological matrices, (3) molecular recognition elements, which specifically capture and detect the target biomarker, (4) signal generation and amplification, and (5) instrumentation for signal read-out. 113, 114 In subsequent studies, the group developed and optimized a hand-held, easy-to-use device 85, 115 (Figure 8A ) in which HRP2-bound, IMAC-functionalized magnetic beads were directly transferred to the sample pad of commercial malaria lateral flow assays. If combined with one of the sample preparation strategies discussed previously (section 3) or integrated with paper or another field-ready substrate, this Ir(III)-based detection strategy could produce a robust and sensitive assay that is applicable in low-resource diagnostic settings. doi = 10.1021/acs.chemrev.8b00136 id = cord-252568-b8sbvy0g author = Marques Neto, Lázaro Moreira title = Role of Metallic Nanoparticles in Vaccinology: Implications for Infectious Disease Vaccine Development date = 2017-03-08 keywords = IFN; response; th1 summary = There is evidence that these particles display adjuvant characteristics, promoting cell recruitment, antigen-presenting cell activation, cytokine production, and inducing a humoral immune response. However, many NPs have been shown to stimulate immune responses, including cell recruitment, activation of antigen (Ag)-presenting cells (APCs), and induction of cytokine and chemokine release. Among the vaccines targeting extracellular bacteria and toxin, two were formulated with lipopolysaccharide (LPS) in glycopeptide Ag. The use of glycoantigen and LPS can trigger an intense response through TLR4 and B cell receptor activation; the presence of gold NPs (AuNPs) may have minimal influence on this response. To understand the possible uses of MeNPs as platforms for vaccines against infectious diseases, analysis is needed of the impact of different physicochemical characteristics of NPs on the innate immune response (Figure 1) . doi = 10.3389/fimmu.2017.00239 id = cord-005595-vzkcin1l author = Massa, P.

It has previously been reported that primary cultures of human fetal brain tissue can be a useful substrate for studying the expression of cell type-specific antigens, e.g. gangliosides, tetanus toxin receptors (Dickson et al., 1982 (Dickson et al., , 1985 , and the present data confirm that they can also be successfully employed to investigate the expression and modulation of HLA molecules. doi = 10.1016/0165-5728(88)90049-5 id = cord-282395-uwxk1o6d author = Mayer, Karin title = Fatal outcome of human coronavirus NL63 infection despite successful viral elimination by IFN‐alpha in a patient with newly diagnosed ALL date = 2016-03-04 keywords = IFN; NL63 summary = doi = 10.1111/ejh.12744 id = cord-334134-fhie2m3u author = Mazaleuskaya, Liudmila title = Protective Role of Toll-like Receptor 3-Induced Type I Interferon in Murine Coronavirus Infection of Macrophages date = 2012-05-24 keywords = IFN; J774A.1; MHV; TLR3 summary = We assessed the effect of triggering TLR2, TLR3, TLR4, and TLR7 with selected ligands on the susceptibility of the J774A.1 macrophage cell line to infection with murine coronavirus (mouse hepatitis virus, [MHV]). These results together with the antiviral effect of poly I:C (Figure 3 ) suggested that the protective role of TLR3 against coronavirus infection in J774A.1 macrophages may be mediated by type I IFN. We hypothesized that the differential effect of TLR ligands on MHV production is due to their variable ability to induce type I IFN crucial for triggering an "antiviral state" and protecting cells from virus infection [26, 38] . In the present study prestimulation of J774A.1 macrophages with poly I:C, a potent type I IFN inducer, resulted in a strong IFN-β response that triggered antiviral immunity and protected macrophages from MHV infection before and after virus adsorption. doi = 10.3390/v4050901 id = cord-000104-3b8b8p61 author = McWhirter, Sarah M. title = A host type I interferon response is induced by cytosolic sensing of the bacterial second messenger cyclic-di-GMP date = 2009-08-31 keywords = Fig; GMP; IFN; dna summary = doi = 10.1084/jem.20082874 id = cord-022226-qxp0gfp3 author = Meager, Anthony title = Interferons Alpha, Beta, and Omega date = 2007-09-02 keywords = IFN; IFNB; IRF-1; Maeyer; gene; human; interferon summary = doi = 10.1016/b978-012498340-3/50026-9 id = cord-355671-t890eixt author = Medina, Gisselle N. title = Impairment of the DeISGylation Activity of Foot-and-Mouth Disease Virus Lpro Causes Attenuation In Vitro and In Vivo date = 2020-06-16 keywords = FMDV; Fig; IFN; Lpro; isg15 summary = FMDV Lpro is a papain-like protease (PLP) known to block the cellular innate immune response, at both the transcriptional and translational level by utilizing different mechanisms, including (i) shutting down translation of host capped mRNAs through the cleavage of the translation initiation factor eIF4G (5, 6); (ii) downregulating IFN mRNA expression by causing degradation of NF-B, IRF-3, IRF-7, and LGP2 (7-10); (iii) targeting the chromatin remodeling machinery to disrupt the expression of IFN and ISG mRNAs (11) ; and (iv) targeting of G3BP1/2 to block stress granule formation (12) . Importantly, engineering of an infectious clone carrying this mutation (LproW105A) rendered a viable FMDV with a perceptible level of attenuation and reduced deISGylation and DUB activity compared with wild-type (WT) virus during infection of porcine cells. To confirm these results using the FMDV host-specific ISGylation machinery during infection, we cloned the porcine ISG15 in a replicationdefective human adenovirus type 5 (Ad5) vector (Fig. 5B) and examined its antiviral activity in swine cells. doi = 10.1128/jvi.00341-20 id = cord-332154-2gej7h1d author = Meier, William A. title = Cytokines and synthetic double-stranded RNA augment the T helper 1 immune response of swine to porcine reproductive and respiratory syndrome virus date = 2004-12-08 keywords = IFN; IL-12; PRRSV summary = Immunization of pigs with a modified live porcine reproductive and respiratory syndrome virus (PRRSV) vaccine initially elicits a weak interferon (IFN)-γ response. Based on the success of this intervention and the noted absence of IFN-a generation during PRRSV infection, the present studies were undertaken to determine if the antiviral adaptive immunity induced by vaccination with PRRS MLV could be modified simply by the co-administration of rIL-12 protein directly, or of either porcine IFN-a or IL-12 indirectly via plasmids expressing these cytokines. Although a similar response was evident during this time period for vaccinated pigs also i.m. injected with exogenous IL-12 either directly as protein or indirectly via IL-12 cDNA, immunized animals that were i.d. inoculated with IL-12 cDNA exhibited an overall 2.7-fold transient increase in the frequency of PRRSV-specific IFN-g SC at 2 weeks post-vaccination.

With clear understanding of the IFN/IFIT (IFN-induced proteins with tetratricopeptide repeats)-based mechanism, NSP16 mutants provide a suitable target for a live attenuated vaccine platform, as well as therapeutic development for both current and future emergent CoV strains. Generation of mutants with changes in the NSP16 KDKE active site resulted in IFN-mediated in vitro and in vivo attenuation of both mouse hepatitis virus (MHV) and SARS-CoV (9, 10) . While a more rapid CPE following both WT and dNSP16 mutant MERS-CoV infections precluded an equivalent finding at late time points, the SARS-CoV results suggest that the absence of NSP16 activity eventually initiates host response changes that contribute to attenuation at late time points. doi = 10.1128/msphere.00346-17 id = cord-333600-k6ws97at author = Mihm, Sabine title = COVID-19: Possible Impact of the Genetic Background in IFNL Genes on Disease Outcomes date = 2020-04-28 keywords = IFN summary = Host control of MHV infection is completely dependent on TLR7 triggering by viral RNA causing an immediate interferon (IFN) response [2] . Sex differences in TLR7 responses have been reported for humans -with female sex better coping with viral infection [4] [5] [6] -which is also a feature of COVID-19. Upon binding viral nucleic acid motifs, TLR7 induces the expression of type I IFNs (IFN-α and IFN-β) and the expression of the more recently described family of type III IFNs (IFN-λ [1] [2] [3] [4] . A common germ line genetic variation within the type III IFN gene locus has been most convincingly shown to determine the host''s capacity to cope with an infection induced by hepatitis C virus (HCV), an enveloped ssRNA virus of positive orientation, too, featuring tropism for liver epithelial cells.

Therefore, we studied whether virus detection and T cell and interferon gene expressions differed between the two main indications of surgery, tonsillar hypertrophy or recurrent tonsillitis. The adjustments for immunologic analyses were chosen using backward stepwise multivariable models that initially included clinical factors and virus infections which significantly differed between the groups (age, self-reported pollen allergy, self-smoking, both adenotomy and tonsillectomy performed, respiratory symptoms one month prior to the operation and bioavailable 25(OH)D level).

Cytopathic effect (CPE) was extensive in vehicle-treated groups infected with either SARS-CoV strain at 120 hpi ( Fig. 2A and 2E) , as evident by the reduced monolayer staining with crystal violet. However, the CPE profile observed in Calu-3 cells suggests that the synergistic inhibitory effect on SARS-CoV replication by IFN-β and IFN-γ is not Vero E6 cell specific. It has been known for more than 25 years that treatment of cells with type I and type II IFN potentiates the antiviral response to levels greater than can be explained by simple additive effects.

The role of IFITM2 in the inhibition of ASFV in Vero cells could be related to impaired endocytosis-mediated viral entry and alterations in the cholesterol efflux, suggesting that IFITM2 is acting at the late endosome, preventing the decapsidation stage of ASFV. Thus, our goal in the current work was to test whether the IFITM family of proteins affected early entry steps of ASFV infection in Vero cell cultures using the cell-adapted Ba71V isolate. Confocal microscopy experiments revealed that, IFITM1 was mainly distributed at the plasma membrane and to a lesser extent in perinuclear compartments, resembling endosomal structures (Fig 3C, lower left panel) , while endogenous IFITM1 was barely detected in Vero cells containing the empty vector (Fig 3C, upper left panel) . doi = 10.1371/journal.pone.0154366 id = cord-285757-fiqx4tll author = Mäkelä, M.

In conclusion, expression of MxA in blood lymphocytes and an apparently systemic type I interferon response is not induced during rhinovirus infection or during most other cases of common cold in young adult patients. In the present study, the induction of a systemic IFN response as reflected by the expression of MxA protein in blood lymphocytes of patients with rhinovirus infection was examined. Our data suggests that type I IFN production in serum is not comparable to that seen in most other respiratory viral infections in vivo, since the rhinovirus-positive patients had only low or no expression of the MxA protein and no IFN-a/b was detectable in serum samples. doi = 10.1007/s100960050370 id = cord-314333-hkyiy1gm author = Nagata, Noriyo title = Mouse-Passaged Severe Acute Respiratory Syndrome-Associated Coronavirus Leads to Lethal Pulmonary Edema and Diffuse Alveolar Damage in Adult but Not Young Mice date = 2008-06-30 keywords = BALB; IFN-; SARS; mouse summary = title: Mouse-Passaged Severe Acute Respiratory Syndrome-Associated Coronavirus Leads to Lethal Pulmonary Edema and Diffuse Alveolar Damage in Adult but Not Young Mice Adult mice showed early and acute excessive proinflammatory responses (ie, cytokine storm) in the lungs after SARS-CoV infection, which led to severe pulmonary edema and diffuse alveolar damage.

In addition, none of the host restriction factors tested (BST2, ISG15, RSAD2 and TRIM1) had significant changes in their expression either at 4-or 8-weeks post-vaccination when compared to prevaccination levels. In this cohort of KoRV vaccinated and endogenously infected koalas, a small but significant increase in the expression of IFN-γ at both 4-and 8-weeks post-vaccination was observed, compared to pre-vaccination levels.

To analyze the in vivo effects of the NADPH oxidase activator phytol versus the effects of the arthritis-inducing compound pristane, global gene-expression profiling was performed. By studying gene-expression profiles and performing pathway analysis, we have identified the importance of an IFN-β-dependent pathway as one molecular mechanism for the arthritis-ameliorating efficacy of NADPH oxidaseactivating compounds. To obtain a more detailed understanding of the molecular mechanism of this regulation, gene-expression profiling experiments were performed on inguinal lymph nodes from rats with pharmacologically (phytol) and genetically (Ncf1) modified NADPH oxidase activity. In this study, we used global gene-expression analysis and quantitative real-time PCR techniques in four separate arthritis experiments in rats to investigate the downstream effects of preventive arthritis treatment with the NADPH oxidase activator phytol. doi = 10.1186/1741-7007-5-19 id = cord-298259-r9rn0yyz author = Omatsu, Tsutomu title = Induction and sequencing of Rousette bat interferon α and β genes date = 2008-07-15 keywords = IFN; Tb-1 summary = To investigate the function of type I IFNs upon viral infection in bats, the nucleic acid, and amino acid sequences of Egyptian Rousette (Rousettus aegyptiacus) IFN-α and -β were characterized. Stimulation of bat primary kidney cells (BPKCs) and bat lung cell lines, Tb-1 Lu, with polyinosinic–polycytidylic acid (poly(I:C)) or exogenous bat type I IFNs resulted in increased type I IFNs mRNA expression in BPKCs, but not in Tb-1 Lu. Characterization of the bat IFN-α and -β genes allows understanding of the immune responses upon stimulation in different tissues, thus providing practical strategies for control and treatment of clinically important diseases. These results are important especially for the virus infection, and suggest that future molecular studies on virus infection experiment of bats in vitro will require careful consideration of the differences of type I IFN expression patterns in different cell types. These data suggested that Ebola virus might evade the anti-viral activity of IFNs in bat cells. doi = 10.1016/j.vetimm.2008.03.004 id = cord-001848-idmj2d7p author = Onabajo, Olusegun O. title = Expression of Interferon Lambda 4 Is Associated with Reduced Proliferation and Increased Cell Death in Human Hepatic Cells date = 2015-11-01 keywords = Fig; HCV; Halo; IFN; Olsson summary = We performed live confocal imaging, cell death and proliferation assays, mRNA expression profiling, protein detection, and antibody blocking assays using transient and inducible stable in vitro systems.

The stable HepG2-ISRE-Luc cells were transfected with corresponding constructs in 96-well plates; untransfected cells were treated with human recombinant interferons-IFNa (2 ng/mL; PBL Assay Science) or custom IFN-l3 (10 ng/ mL). Previously, by performing Western blot analysis, we were unable to detect IFN-l4 in culture media of HepG2 cells transiently transfected with an IFN-l4-producing construct, even though this transfection resulted in strong activation of interferon signaling (Prokunina-Olsson and others 2013).

Importantly, all major aspects of SARS-CoV-2-induced pDC activation were inhibited by hydroxychloroquine, including P2and P3-pDC differentiation, the expression of maturation markers, and the production of interferon-α and inflammatory cytokines. Interestingly, pDC responded to SARS-CoV-2 by a complete activation program, including diversification into effector subsets, production of type I and type III IFN, as well as inflammatory cytokines. We also showed that hydroxychloroquine, an antimalarial drug proposed for treatment of COVID-19 patients (Das et al., 2020; Mahévas et al., 2020) , inhibits SARS-CoV-2-induced pDC activation and IFN production in a dose-dependent manner. Following 24 hours of culture, we found that HCQ inhibited pDC diversification in response to SARS-CoV-2, which is similar to the decrease observed with Flu, used as a positive control ( Fig 4A) . doi = 10.1101/2020.07.10.197343 id = cord-001359-c1uom5f7 author = Oslund, Karen L. title = Synergistic Up-Regulation of CXCL10 by Virus and IFN γ in Human Airway Epithelial Cells date = 2014-07-17 keywords = CXCL10; IFN; IFNAR summary = doi = 10.1371/journal.pone.0100978 id = cord-296948-sqxrwgif author = Paquin, Ashley title = Comparative Functional Analysis of 12 Mammalian IFN-λ4 Orthologs date = 2016-01-01 keywords = Halo; IFN; MAB summary = doi = 10.1089/jir.2015.0096 id = cord-268341-103xf3dw author = Parra, Beatriz title = Kinetics of Cytokine mRNA Expression in the Central Nervous System Following Lethal and Nonlethal Coronavirus-Induced Acute Encephalomyelitis date = 1997-07-07 keywords = CNS; IFN; JHMV; day summary = doi = 10.1006/viro.1997.8613 id = cord-335245-1eksm537 author = Pattyn, Els title = HyperISGylation of Old World Monkey ISG15 in Human Cells date = 2008-06-18 keywords = IFN; cell; figure; isg15 summary = Western blot analysis visualized more efficient conjugation of OWmISG15 relative to HuISG15 in human (Hu), monkey and mouse (Mo) cell-lines.

To confirm the role of IFN-γ as the major cytokine contributing to suppression of JHMV replication in infected NPC cultures, monoclonal antibody blockade against the IFN-γ receptor was performed on NPCs before and during treatment with virusspecific CD4þ T cell enriched media. Impaired expression of MHC class II following IFN-γ-treatment of infected NPCs may be a mechanism employed to subvert detection by infiltrating virus-specific CD4þ T cells. doi = 10.1016/j.virol.2013.11.025 id = cord-005664-n4xv247l author = Plötz, Frans B. title = Mechanical ventilation alters the immune response in children without lung pathology date = 2002-01-15 keywords = IFN; TNF; th1 summary = In the tracheal aspirates the immune balance was characterized by a proinflammatory response pattern, with a significant increase in TNF-α and IL-6 concentrations; concentrations of anti-inflammatory mediators remained very low.

Conclusions: Two hours of servoflurane and mechanical ventilation using a tidal volume of 10 ml/kg is associated with remarkable changes in the immune response in infants without preexisting lung pathology undergoing cardiac catheterization. The major finding of the present study is that exposing infants with normal lung function to 2 h of volatile anesthetics, mechanical ventilation, and cardiac catheterization is associated with remarkable changes in immune responses. We observed a proinflammatory response in the lungs with a significant increase in TNF-α, while antiinflammatory cytokine concentrations in tracheal aspirates remained virtually unchanged, just above the detection level. doi = 10.1007/s00134-002-1216-7 id = cord-005393-rhji4io9 author = Popko, Brian title = The effects of interferon-γ on the central nervous system date = 1997 keywords = CNS; EAE; IFN; IFN-7; MHC summary = doi = 10.1007/bf02740619 id = cord-273144-er6irjw3 author = Powell, Fiona title = Development of reagents to study the turkey''s immune response: Cloning and characterisation of two turkey cytokines, interleukin (IL)-10 and IL-13 date = 2012-06-15 keywords = IFN-; IL-10; chicken; turkey summary = The availability of genome sequences for other avian species, including the zebrafinch (Warren et al., 2010) , the turkey (Dalloul et al., 2010) and the duck (http://pre.ensembl.org/Anas platyrhyncos/Info/), should allow identification and subsequent characterisation of their immune gene repertoires.

The PPI network analysis indicates that the pathways are enriched in host response to virus infection, type I interferons signaling, and cytokine activation. [74] reported high SARS-CoV-2 loads very early during infection, suggesting that the virus may have developed arsenals that is able to delay the IFN response by inhibiting innate immune signaling. doi = 10.1016/j.ijbiomac.2020.06.228 id = cord-343824-00mqmpzw author = Qian, Wei title = The C-Terminal Effector Domain of Non-Structural Protein 1 of Influenza A Virus Blocks IFN-β Production by Targeting TNF Receptor-Associated Factor 3 date = 2017-07-03 keywords = IFN; TRAF3; ns1/126; rig summary = title: The C-Terminal Effector Domain of Non-Structural Protein 1 of Influenza A Virus Blocks IFN-β Production by Targeting TNF Receptor-Associated Factor 3 Influenza A virus non-structural protein 1 (NS1) antagonizes interferon response through diverse strategies, particularly by inhibiting the activation of interferon regulatory factor 3 (IRF3) and IFN-β transcription. Hence, binding of the NS1 protein to dsRNA, RIG-I, and TRIM25 has not established that these NS1 interactions are responsible for inhibiting the activation of IRF3 and IFN transcription. These data reveal a novel mechanism for how the influenza A virus NS1 protein induces inhibition of the host IFN production and may provide a potential target for antiviral drug development. However, our study demonstrated that the influenza A virus NS1 ED targets TRAF3, subsequently inhibits IFN production, implying that TRAF3 is a key factor involved for IAV to escape host innate immune responses. doi = 10.3389/fimmu.2017.00779 id = cord-299756-m0va36er author = Raaben, Matthijs title = Type I interferon receptor-independent and -dependent host transcriptional responses to mouse hepatitis coronavirus infection in vivo date = 2009-08-03 keywords = IFN; MHV; type summary = As the BALB/c and the IFNAR-/129SvEv mice demonstrated very similar viral loads in their brains, we also compared their gene expression profiles upon infection with MHV in order to identify type I IFN-dependent transcriptional responses. CONCLUSION: Transcriptional profiling of mice infected with MHV demonstrated the induction of a robust IFN response, which correlated with the viral load. Furthermore, gene expression profiling of 129SvEv mice lacking the type I IFN receptor, which are not able to control the MHV infection [11] , allowed us to identify type I IFN-independent transcriptional responses. To study the role of type I IFN-independent and -dependent gene expression in the control of MHV infection in vivo in more detail, we next made use of the IFNAR-/-mice [30] . Transcriptional profiling of mice infected with MHV demonstrated the induction of a robust IFN response, which correlated with the viral load. doi = 10.1186/1471-2164-10-350 id = cord-329190-kv9n2qj3 author = Rabaan, Ali A. title = A review of candidate therapies for Middle East respiratory syndrome from a molecular perspective date = 2017-09-01 keywords = CoV; East; IFN; MERS; Middle; SARS summary = The current therapies have mainly been adapted from severe acute respiratory syndrome (SARS-CoV) treatments, including broad-spectrum antibiotics, corticosteroids, interferons, ribavirin, lopinavir–ritonavir or mycophenolate mofetil, and have not been subject to well-organized clinical trials.

Previous studies of dogs using the "LbSapSal" vaccine displayed higher counts of circulating and Leishmania-specific CD8 + T cells in addition to high nitric oxide (NO) production [22] and reduction of splenic parasite load [27] . chagasi-challenge (T 90) demonstrated that "LbSapSal" group showed a significant increase of TNF-α levels (P<0.05) upon VSA-stimulation as compared to "Sal" and "LbSal" groups ( Fig 1A, middle panel) . The results observed at the post-vaccination period (T 3rd ) demonstrated that the "LbSal" group showed a significant reduction in the IL-10 levels (P<0.05) upon VSA-stimulation as compared to the "Sal" group ( Fig 2B, middle panel) . doi = 10.1371/journal.pone.0161169 id = cord-012497-n5pu1yeu author = Rogers, Meredith C. title = STAT2 Limits Host Species Specificity of Human Metapneumovirus date = 2020-07-04 keywords = HMPV; IFN; STAT2 summary = Finally, we sought to understand the in vivo role of STAT2 by infecting hSTAT2 knock-in mice with HMPV, and found that mice had increased weight loss, inhibition of type I interferon signaling, and a Th2-polarized cytokine profile compared to WT mice. Mouse models for HMPV have been developed, but mice are only semi-permissive for HMPV, requiring a high viral inoculum for productive in vivo infection ( [25] and unpublished observations), which may be due to species differences in the innate immune proteins antagonized by the virus. To better understand the global consequences of substituting human STAT2 into mice in vivo, we performed multiplex cytokine analysis on lung homogenates of HMPV-infected hSTAT2 KI and WT mice at day five after high-dose inoculation, as day five represents a time point that bridges innate and adaptive immunity. doi = 10.3390/v12070724 id = cord-341324-f9g9gitn author = Rojas, José M. title = Viral pathogen-induced mechanisms to antagonize mammalian interferon (IFN) signaling pathway date = 2020-10-21 keywords = IFN; IRF3; PRR; RNA; protein; rig; virus summary = This includes for instance cooperating in PRR recognition of viral PAMPs, stabilizing signaling complexes to improve their resistance to degradation, stopping virus entry, blocking viral capsid formation, impairing trafficking and budding of virions from the infected cells, but also modulating the IFN response to avoid the toxicity of these potent immune mediators. The phosphorylated STAT1/STAT2 heterodimer associates with interferon regulatory factor 9 (IRF9) to form the transcriptional factor complex ISGF3, which translocate to the nucleus and binds the IFN-response elements (ISRE) in ISG promoters leading to the expression of ISG products [36] (Fig. 2 The oligoadenylate synthetase (OAS)-latent RNase (RNase L) pathway is another IFN-inducible pathway that provides the cell with an effector mechanism upon recognition of viral dsRNA (reviewed in [44] ). doi = 10.1007/s00018-020-03671-z id = cord-339991-k8z6v2vx author = Rong, Q. title = Multiple mechanisms for HSV-1 induction of interferon α production by peripheral blood mononuclear cells date = 2003 keywords = HSV; IFN; MOMC summary = UV-inactivated, infectious, and other forms of herpes simplex virus 1 (HSV-1) induced interferon (IFN) production by different routes in myeloid origin mononuclear cells (MOMC) (consisting predominantly of monocytes). Comparison of the activities of different strains of infectious HSV, UV-inactivated HSV, and a mutant HSV incapable of penetration (K T) [9] and results of treatment with a mannose receptor antagonist indicate that there are more than one mechanism for HSV induction of interferon in the MOMC origin cell populations. The greater response to UV-inactivated virus suggests that non-infectious virions and possibly HSV infected cell debris are the more potent activators of IFN α production and that replicating virus can limit the induction of interferon production as a means of escaping host protection.

IFN-γ mRNA expression was observed in the lymph nodes and lungs of pigs infected with wild-type PRRSV strain SDSU-23983. The purpose of this study was to evaluate the production of IFN-␥ in pigs following infection with PRRSV and to characterize the mechanism of IFN-␥ action following infection of MARC-145 cells with wild-type and culture adapted PRRSV isolates. The results show that IFN-␥ efficiently inhibits PRRSV replication in MARC-145 cells, and at least part of the antiviral activity may be through PKR. IFN-␥ mRNA expression was detected in the lymph nodes from two of the 3 pigs infected with the wild-type P6 virus (Fig. 1) . Consistent with other reports describing the presence of cell-mediated immunity during PRRSV infection [4, 31] , we observed IFN-␥ mRNA expression in lymph nodes and lungs of PRRSV-infected pigs (Fig. 1) .

PRRSV-specific antibody was measured in sera using the HerdCheck ® PRRS ELISA (IDEXX) and performed by personnel at Kansas State University Veterinary Diagnostic Laboratory. As shown in Fig. 4A , IFN-␥ and TNF-␣ PCR products were not detected in lung, lymph node or placenta from the non-infected fetuses.

The uptake of MBP by B cells and the presentation of MBP-derive peptides to T helper (Th) cells by B cells may be promoted by the formation of complement (C) activating immune complexes (ICs) between MBP and natural autoantibodies in healthy individuals and disease-associated anti-MBP antibodies in MS patients, respectively. While MBP did not induce measurable proliferation of B cells nor CD4 þ T cells, we observed the production of TNF-a, IFN-g and IL-10 by PBMC in response to incubation with MBP in the presence of sera from healthy controls as well as sera from MS patients. In conclusion, the results of this study suggest an involvement of the ASMase in the activation, expansion or maturation of virus-specific CD8 þ T cells during the acute infection of mice with the LCM virus. doi = 10.1111/j.0300-9475.2004.01423an.x id = cord-263862-zzys31e9 author = Ryan, Elizabeth J. title = The Canarypox-virus vaccine vector ALVAC triggers the release of IFN-γ by Natural Killer (NK) cells enhancing Th1 polarization date = 2007-04-30 keywords = ALVAC; Fig; IFN- summary = doi = 10.1016/j.vaccine.2006.12.048 id = cord-023425-3sjsogvq author = Røntved, C.

These include antivirals (remdesivir, lopinavir/ritonavir, umifenovir, and favipiravir), interferon, antimalarials (chloroquine/hydroxychloroquine), antiparasitic drugs (ivermectin and nitazoxanide), biologics (monoclonal antibodies and interleukin receptor antagonist), cellular therapies (mesenchymal stem cells and natural killer cells), convalescent plasma, and cytokine adsorber. Though several observational studies have claimed many of these agents to be effective based on their in vitro activities and extrapolated evidence from SARS and Middle East respiratory syndrome (MERS) epidemics, the currently available data remains inconclusive because of ill-defined patient selection criteria, small sample size, lack of concurrent controls, and use of intermediary outcomes instead of patient-relevant outcomes. doi = 10.3389/fphar.2020.585888 id = cord-265697-bbvlowyo author = Sang, Eric R. title = Integrate structural analysis, isoform diversity, and interferon-inductive propensity of ACE2 to predict SARS-CoV2 susceptibility in vertebrates date = 2020-08-31 keywords = ACE2; IFN; RBD; SARS summary = doi = 10.1016/j.heliyon.2020.e04818 id = cord-315483-l6dm82pp author = Santhakumar, Diwakar title = Chicken Interferon-induced Protein with Tetratricopeptide Repeats 5 Antagonizes Replication of RNA Viruses date = 2018-05-01 keywords = DF-1; Fig; GFP; IFN; NDV; RNA; Supplementary; ifit5 summary = To confirm the sequence of the cDNA and to identify the genomic structure of the identified IFIT gene, the transcript was amplified from RNA extracted from NDV-infected CEFs.

The levels of chIFN-β gene induction was proportional to the NDV replication (Fig. 2D) , therefore, it can be inferred that the virus-induced expression of chicken IFIT5 is IFN-dependent and that chIFIT5 is an early-ISG with capacity to modulate initial steps of virus life cycle. To compare anti-viral effects of chIFIT5 (only IFIT gene identified in chickens so far) with its orthologous and homologous human proteins, huIFIT1, huIFIT2, huIFIT3 and huIFIT5 were expressed in chicken cells and antiviral affect was monitored (Fig. 5A ). doi = 10.1038/s41598-018-24905-y id = cord-317499-mxt7stat author = Saraya, Takeshi title = Epidemiology of virus-induced asthma exacerbations: with special reference to the role of human rhinovirus date = 2014-05-26 keywords = HRV; IFN; infection summary = Table 1 shows the frequency of HRV infection in various adult respiratory diseases such as exacerbation of asthma (Nicholson et al., 1993; Atmar et al., 1998; Tan et al., 2003) , common cold (Makela et al., 1998; van Gageldonk-Lafeber et al., 2005) , exacerbation of COPD (Seemungal et al., 2001; Rohde et al., 2003; Tan et al., 2003; Beckham et al., 2005; Papi et al., 2006; Hutchinson et al., 2007; Ko et al., 2007; McManus et al., 2008; Kherad et al., 2010; Dimopoulos et al., 2012; Perotin et al., 2013) , community acquired pneumonia (Jennings et al., 2008; Johnstone et al., 2008; Johansson et al., 2010; Lieberman et al., 2010; Fry et al., 2011; Wootton et al., 2011; Luchsinger et al., 2013; Takahashi et al., 2013; Huijskens et al., 2014) , exacerbation of idiopathic pulmonary fibrosis (Wootton et al., 2011) , and asymptomatic infection (Fry et al., 2011) . doi = 10.3389/fmicb.2014.00226 id = cord-271250-ywb26cq6 author = Sarkar, Indranil title = Selection of adjuvants for vaccines targeting specific pathogens date = 2019-04-22 keywords = AS01; IFN; MF59; adjuvant; cell; response; vaccine summary = In-depth understanding of the role of adjuvants in activating the innate immune system, combined with systems vaccinology approaches, have led to the development of next-generation, novel adjuvants that can be used in vaccines against challenging pathogens and in specific target populations. Intact MyD88 signaling in each of the three types of APCs (DCs, macrophages and B cells) is essential for robust activity of TLR ligand-based vaccine adjuvants (PorB, a TLR2 ligand and CpG, a TLR9 ligand) such as induction of in vivo cytokine responses, germinal center (GC) formation and antibody production [49] .

RESULTS: Transfer of GKO memory CD4(+) T cells into infected SCID mice induced rapid mortality compared to recipients of WT memory CD4(+) T cells, despite similar virus control and demyelination. Overall these data confirm IFN-γ-mediated control of CNS neutrophil infiltration and suggested a protective role of IFN-γ during viral encephalitis, via inhibiting IL-17 effector function by either directly reducing Th17 cell expansion and/or CNS entry, or limiting GM-CSF production. Although GM-CSF expression is reduced by IFN-γ [27] , the data do not support a pathogenic role of GM-CSF in early mortality of JHMV-infected GKO recipients. doi = 10.1186/1742-2094-9-104 id = cord-007689-0vpp3xdl author = Schlee, M. title = Beyond Double-Stranded RNA-Type I IFN Induction by 3pRNA and Other Viral Nucleic Acids date = 2007 keywords = IFN; RNA; rig summary = doi = 10.1007/978-3-540-71329-6_11 id = cord-307598-p54p7enk author = Schlee, Martin title = Master sensors of pathogenic RNA – RIG-I like receptors date = 2013-07-01 keywords = CTD; IFN; MDA5; RNA; rig summary = Similar to TLRs, RIG-I and MDA5 induce type I IFN and chemokines (but no IL12) upon activation by viral but also bacterial RNA.

Before 5 triphosphate was identified as the crucial RNA modification to induce RIG-I activation, Marques and colleagues observed that synthetic blunt ended dsRNA oligonucleotides can stimulate RIG-I ( Fig. 3 ) (Marques et al.

In this review I discuss the diverse modes of biological actions of IFN-Is and how these are related to biophysical parameters of IFN-I–receptor interaction and cell-type specificity in light of the large variety of binding affinities of the different IFN-I subtypes towards the common interferon receptor. Thereby, it inhibits the nuclear transport of phosphorylated STAT1, rendering cells refractory to IFN-Is. Another example of viral mechanisms that evolved to eliminate IFN-I functions in inducing innate immunity is given by the SARS corona virus, where both the production of IFNb and the IFN-I induced signaling are attenuated. This gene was found to preferentially cleave the ubiquitin-like modifier interferon-stimulated gene 15 (ISG15), FIGURE 4 | SARS-CoV-2 has multiple effects on the immune system, including inhibition of IFNb production, which results in ISGs not to be produced, CD4+ and CD8+ exhaustion and increased levels of pro-inflammatory proteins (TNFa, IL6, NF-kB). doi = 10.3389/fimmu.2020.595739 id = cord-299949-kmn53e2z author = Schultz, Kimberly L.W. title = Immune Responses to Viruses in the CNS date = 2016-05-09 keywords = CNS; IFN summary = For recovery from infection, the immune response in the central nervous system (CNS) must eliminate or control virus replication without destroying nonrenewable, essential cells. For recovery after virus infection of the central nervous system (CNS), the essential, nonrenewable nature of neurons requires a fine-tuned immune response that controls virus replication without damaging neuronal function. Detailed studies of immune responses to neurotropic viruses have included neuronal infections with rabies virus, flaviviruses, and alphaviruses, as well as infection of multiple cell types with natural mouse pathogens such as Theiler''s murine encephalomyelitis virus (TMEV), mouse hepatitis virus (MHV), and lymphocytic choriomeningitis virus (LCMV). Resident cells in the nervous system, including neurons, play an active role in the immune response (Schultz et al., 2014; O''Donnell et al., 2012; Chakraborty et al., 2010; Daffis et al., 2008a; Castorena et al., 2008; Daffis et al., 2007; Commonly used in mouse models of viral encephalitis. doi = 10.1016/b978-0-12-374279-7.14022-6 id = cord-312075-asbt0mcj author = Schulz, Katharina S. title = Viral Evasion Strategies in Type I IFN Signaling – A Summary of Recent Developments date = 2016-11-11 keywords = IFN; IRF3; TBK1; rig summary = Human T-cell lymphotropic virus type I (HTLV-1) protein Tax disrupts innate immune signaling in multiple ways: it binds to the RIP homotypic interaction motif (RHIM) domains of RIP-1 and disrupts the interaction between RIP-1 and RIG-I or MDA-5 and the activation of the type I IFN promoter. Upon stimulation, TBK1 and IKKε are recruited by adaptor proteins to signaling complexes to be activated by phosphorylation on Ser172 and both have been shown to be subjected to K63-linked polyubiquitination [reviewed in Ref. Interestingly, when a recent study tested how the rabies virus P protein of street strains behaves compared to laboratory-adapted strains with regard to the induction of type I IFN, they found that both street strains and laboratory strains inhibit TBK1-mediated signaling, but only the P protein of street strains also interacts with and inhibits IKKε-inducible IRF3dependent IFNβ expression (88) (Figure 1) .

Moreover, increasing evidence suggests that at least some +RNA viruses in fact occupy or hijack MAM-membranes during infection, as MAMs of HCV-infected cells were found to contain proteins involved in virus assembly and fully assembled virions [111] . At last, based on recent studies that demonstrated how IFN-g inducible GTPases are capable of disrupting PVs, we discussed the possibility of a general function of IFN-inducible GTPases in the targeting of viral ROs.

IFN antagonism of SARS coronavirus M protein was mediated by N-terminal TM1 (amino acids 1-38), which targets M protein to the Golgi complex and associates with TRAF3 to prevent it from interacting with TANK, TBK1 and IKKe. Our findings provide additional molecular details for suppression of type I IFN production by SARS coronavirus M protein. Notably, human coronavirus HKU1 M protein also targets the Golgi complex, interacts with TRAF3, but does not suppress IFN production. doi = 10.1038/cmi.2013.61 id = cord-341278-klv9jdm8 author = Smith, Abigail L. title = The role of gamma interferon in infection of susceptible mice with murine coronavirus, MHV-JHM date = 1991 keywords = IFN-7; JHM; MHV summary = Infection of BALB/c mice with mouse hepatitis virus, strain JHM (MHV-JHM), at any of several intervals relative to ovalbumin (OVA) administration resulted in elevated OVA-specific IgG 2 a titers. Serum IFN-γ was not detected, but treatment of MHV-JHM-infected mice with monoclonal anti-IFN-γ antibody resulted in high mortality with decreased survival times, enhanced virus titers in liver and spleen, and more severe virus-associated pathology, compared to mock-treated, infected mice. Sera from mice infected with MHV-JHM one day prior to OVA administration contained substantially elevated levels of antigen-specific IgG2 a on day 7 (Table 1 ) with geometric mean titers that were 17 times control (OVA only) values at that interval. The elevated IgG 2 a OVA-specific response of most groups of MHV-infected mice and the preferential production of this isotype by mice infected one day prior to antigen administration suggested that these mice were producing IFNy.

TLR stimulation after phagocytosis activates the NF-κB signaling cascade, resulting in the release of inflammatory cytokines such as TNF-α, IL-1, and IL-6 from monocytes [4] to control virus infections by direct antiviral mechanisms and the recruitment of other leukocytes. Taken together, these findings suggest that type I IFN signaling drives a balance of pro-and anti-inflammatory effects on the functions of monocytes and neutrophils in response to viral infections; providing protective immunity while simultaneously limiting immunopathology. Importantly, viruses and virus-mediated tissue damage stimulate both neutrophils and monocytes, triggering a cascade of cytokine/chemokine-mediated innate immune responses. doi = 10.3390/v11020168 id = cord-023419-lnmc6vv5 author = Steinhauer, C. title = High‐Throughput Proteomics on Antibody‐based Microarrays: the Importance of Probe and Surface Design date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = We demonstrate that Cw6 þ psoriasis patients had significant CD8 þ T-cell IFN-g responses to peptides from K17 and M6 protein selected on the basis of sequence homology and predicted HLA-Cw*0602 binding.

X-ray data have suggested that the methylation of rRNA requires the formation of this complex with involvement of four fibrillarin molecules interacting with different regions of the target rRNAs. The yeast equivalent of fibrillarin, NOP1, has been more extensively studied than the human counterpart but fibrillarin is a well-conserved protein in most organisms, reinforcing the notion that all post-transcriptional processes involving fibrillarin such as chemical modification (methylation) of rRNA, pre-rRNA cleavage and ribosome assembly are essential for proper cellular functioning (Rodriguez-Corona et al. Deffrasnes and colleagues showed that siRNA-mediated knockdown of fibrillarin expression dramatically reduced HeV protein production and viral genome replication but did not impact viral fusion, and that fibrillarin catalytic activity was essential to henipavirus infection. doi = 10.1007/82_2017_28 id = cord-318339-j35w1vsw author = Stockman, Lauren J title = SARS: Systematic Review of Treatment Effects date = 2006-09-12 keywords = IFN; SARS; Table summary = METHODS AND FINDINGS: In response to the WHO request we conducted a systematic review of the published literature on ribavirin, corticosteroids, lopinavir and ritonavir (LPV/r), type I interferon (IFN), intravenous immunoglobulin (IVIG), and SARS convalescent plasma from both in vitro studies and in SARS patients.

To support the search for effective antiviral treatments, we evaluated the susceptibility of SARS CoV isolates (detailed studies were performed with the Tor2 isolate [Toronto, Canada]) to ribavirin and interferon (IFN)-a-2b in vitro. Our data indicate that ribavirin does not inhibit the virus at concentrations attainable in human serum but that IFN-a-2b may be useful and deserves further evaluation as a therapeutic agent. To quantify the effect of IFN-a-2b on the replication of the SARS CoV, Vero E6 cells were infected at an MOI of 0.001 and were incubated in the presence IFN-a-2b (0-5000 IU/mL), as described above. Whether combined therapy with IFN-a-2b and ribavirin would inhibit the replication of the SARS CoV in vitro has not yet been evaluated; the combination is more effective than either agent used alone for the treatment of HCV infection in humans. doi = 10.1086/382597 id = cord-023374-87ob1exq author = Sukhija, S. title = Levels, Complement Activity and Polymorphisms of Mannan‐Binding Lectin in Patients of Bronchial Asthma with Allergic Rhinitis date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = doi = 10.1111/j.0300-9475.2004.01423ai.x id = cord-297512-l9re9h4j author = Sultana, Shehnaz title = Interferon gamma (IFNγ) +874A/T gene polymorphism in South Indian ischemic stroke patients date = 2011-07-17 keywords = IFN; stroke summary = doi = 10.5214/ans.0972.7531.1118305 id = cord-256788-h4iv8crq author = Sumino, Kaharu title = Antiviral IFN-γ responses of monocytes at birth predict respiratory tract illness in the first year of life date = 2012-03-27 keywords = IFN; IFNG; RSV; respiratory summary = doi = 10.1016/j.jaci.2012.02.033 id = cord-259669-fod4xkd7 author = Summerfield, Artur title = The porcine dendritic cell family date = 2008-06-06 keywords = IFN; MHC; cell summary = Being strategically located at sites of pathogen entry, such as mucosal surfaces and Considering the pivotal roles played by dendritic cells (DCs) in both innate and adaptive immune responses, advances in the field of porcine immunology DC biology have recently progressed rapidly.

In support of the above observations, a retrospective study of 41 patients with COVID-19 2 showed that most SARS-CoV-2 infected patients present clinically with mild symptoms, while a minority of patients progressively declined from the infection and eventually died of acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MOD).

At 12 WPC, multiparametric flow cytometry analysis indicated that mice immunized with PAN-Cf elicited a significantly higher percent of antigen specific double cytokine (IFN-γ, TNF-α + ) and single cytokine (IFN-γ) producing CD8 + T cells compared with non-vaccinated and Mycopar® vaccinated mice (Fig. 4 ). doi = 10.1038/s41541-020-0164-y id = cord-354620-xf6glr2h author = Tian, Bin title = Isolation and Selection of Duck Primary Cells as Pathogenic and Innate Immunologic Cell Models for Duck Plague Virus date = 2020-01-28 keywords = DPV; IFN; cell; figure summary = Our study provided practical methods for isolating and culturing duck primary cells, and our results will facilitate further investigations of organ tropism, innate immune responses, latent infection, and the effectiveness of antiviral drugs for treating DPV and potentially other aerial bird pathogens. In the present study, we isolated five types of duck primary cells [duck embryo fibroblasts (DEFs), neurons, astrocytes, peripheral blood mononuclear cells (PBMCs), and monocytes/macrophages] to identify appropriate cell models for DPV, using tropism infection and innate immunologic assays. Upon stimulation with DNA viruses, monocytes/macrophages exhibit higher levels of IFN-β, ISG, and inflammatory cytokine expression than DEFs, neurons, astrocytes, and PBMCs. To elucidate the mechanisms associated with the different responses of the five types of duck primary cells to DNA and RNA virus analogs, the basal levels of innate immune factors were compared. doi = 10.3389/fimmu.2019.03131 id = cord-265005-e6rpryrh author = Tomasello, Elena title = Harnessing Mechanistic Knowledge on Beneficial Versus Deleterious IFN-I Effects to Design Innovative Immunotherapies Targeting Cytokine Activity to Specific Cell Types date = 2014-10-30 keywords = CD4; CD8; HCV; IFN; cell; figure; infection; type summary = We will discuss the expression patterns and functions of endosomal TLRs with regards to IFN production in uninfected specialized immune cell types, pDCs and XCR1 + DCs. Plasmacytoid DCs uniquely produce very large amounts of IFNs in response to in vitro stimulation with many viruses, without being infected (46) . Under these conditions, to promote health over disease, the benefits for the host of producing high circulating levels of IFNs in order to induce widespread cell-intrinsic anti-viral defenses might prevail over the deleterious effects that this could cause on certain cell types or tissues. Subcapsular sinus macrophages rapidly become infected by viruses incoming from the lymph and produce large amounts of IFNs. This altruistic suicide prevents virus dissemination to other adjacent cell types and promotes the induction of innate and adaptive anti-viral immunity (87) . doi = 10.3389/fimmu.2014.00526 id = cord-029488-l11ufs6k author = Tomita, Kengo title = Vascular endothelial growth factor contributes to lung vascular hyperpermeability in sepsis-associated acute lung injury date = 2020-07-21 keywords = ALI; IFN; LPS; VEGF; vascular summary = Expression levels of VEGF were significantly reduced in lung tissues from mice with both intranasal LPS administration and cecal ligation and puncture (CLP)-induced sepsis, which may stem from decreases in non-endothelial cells-dependent VEGF production in the lungs. In support of this assumption, stimulation with LPS and interferon-γ (IFN-γ) significantly increased VEGF in human pulmonary microvascular endothelial cells (HPMECs) at mRNA and protein levels. Taken together, our results indicate that VEGF can contribute to the development of non-cardiogenic lung edema in sepsis-associated ALI due to increased VEGF secretion from pulmonary vascular endothelial cells through multiple MAPK-dependent pathways. We thus examined whether expression of VEGF in human pulmonary microvascular endothelial cells is regulated by MAPKs. When HPMEC-ST1.6R cells were treated with PD98059, an inhibitor of MAPK kinase which is an ERK1/2 upstream activator, or SB203580, which is widely used as a specific inhibitor of p38 MAPK, the LPS/IFN-γinduced increase in VEGF protein levels was strongly blocked (Fig. 4b) . doi = 10.1007/s00210-020-01947-6 id = cord-348993-8r4fhzlm author = Tomosada, Yohsuke title = Nasally administered Lactobacillus rhamnosus strains differentially modulate respiratory antiviral immune responses and induce protection against respiratory syncytial virus infection date = 2013-08-15 keywords = IFN; Lr05; Lr06; RSV; figure summary = CONCLUSIONS: The present work demonstrated that nasal administration of immunobiotics is able to beneficially modulate the immune response triggered by TLR3/RIG-I activation in the respiratory tract and to increase the resistance of mice to the challenge with RSV. Considering this background, the aims of this study were: a) to investigate whether the nasal administration of Lr05 or Lr06 are able to improve respiratory antiviral defenses and beneficially modulate the immune response triggered by TLR3/RIG-I activation; b) to evaluate whether viability of Lr05 or Lr05 is indispensable to modulate respiratory immunity considering that it was reported that heat-killed lactobacilli strains are able to improve lung defenses [11, 15, 16] and; c) to conclusively demonstrate the protective effect of Lr05 and Lr06 by evaluating their capacity to improve the resistance of infant mice against RSV challenge. doi = 10.1186/1471-2172-14-40 id = cord-274247-5qiwui6u author = Torrecilhas, A C T title = Interference of natural mouse hepatitis virus infection with cytokine production and susceptibility to Trypanosoma cruzi date = 1999-03-01 keywords = BALB; IFN; MHV summary = doi = 10.1046/j.1365-2567.1999.00719.x id = cord-252950-eiphxwmn author = Trouillet-Assant, Sophie title = Type I IFN immunoprofiling in COVID-19 patients date = 2020-04-29 keywords = France; IFN summary = COVID patients in ICU present a high mortality rate and immunoprofiling reveals heterogeneous IFN-α2 production with about 20% of critically-ill patients unable to produce IFN-α2, highlighting the immune response heterogeneity and opening avenues for targeted therapies. 42 Capsule summary: 43 COVID patients in ICU present a high mortality rate and immunoprofiling reveals heterogeneous α2 production with about 20% of critically-ill patients unable to produce IFN-α2, highlighting the 45 immune response heterogeneity and opening avenues for targeted therapies. Various immunosuppressive drugs, including IL-6 blockers or JAK-STAT signaling inhibitors have been 56 suggested for the treatment of SARS-COV-2 infection 2 whereas additional clinical trials are evaluating 57 the use of recombinant interferon to foster host antiviral response. To date, IFN-I response has not been evaluated in COVID-19 60 patients and its contribution to the viral control and inflammation is unknown. We further explored a larger cohort of 26 critically ill COVID patients from one of the intensive care 75 unit (ICU) at Hospices Civils de Lyon (Lyon, France). doi = 10.1016/j.jaci.2020.04.029 id = cord-270498-hh6h50t2 author = Tseng, Chin-Kai title = Celastrol inhibits hepatitis C virus replication by upregulating heme oxygenase-1 via the JNK MAPK/Nrf2 pathway in human hepatoma cells date = 2017-09-19 keywords = HCV; HO-1; IFN; Nrf2 summary = Celastrol-induced heme oxygenase 1 (HO-1) expression promoted antiviral interferon responses and inhibition of NS3/4A protease activity, thereby blocking HCV replication. These antiviral effects were abrogated by treatment with the HO-1-specific inhibitor SnMP or silencing of HO-1 expression by transfection of shRNA, which indicates that HO-1 induction contributes to the anti-HCV activity of celastrol. In this study, our data revealed that celastrol significantly inhibits HCV replication, and that the anti-HCV effect of celastrol was attenuated by the HO-1 specific inhibitor tin mesoporphyrin (SnMP) or HO-1 gene expression silencing. Celastrol-mediated HO-1 induction contributed to the anti-HCV action through inducing antiviral IFN response and inhibiting HCV NS3 protease activity. As shown in Fig. 7B , HO-1 RNA expression levels were induced by celastrol compared with non-celastrol treated cells and the JNK inhibitor SP600125 significantly reduced the HO-1 inductive effect of celastrol. In the present study, we found that a natural product celastrol could effectively inhibit HCV NS3/4A protease activity and enhance IFN-mediated antiviral gene expression through HO-1 induction (Figs. doi = 10.1016/j.antiviral.2017.09.010 id = cord-321050-yabt72jf author = Tuttle, Kathryn D. title = JAK1 inhibition blocks lethal sterile immune responses: implications for COVID-19 therapy date = 2020-04-09 keywords = Dp16; IFN; P(I summary = Increasing evidence supports the notion that mortality during infections with SARS-CoV-2, which causes coronavirus disease of 2019 , is driven by the exacerbated immune response to the virus, leading to a cascade of events involving a cytokine storm and acute respiratory distress syndrome (ARDS), often accompanied by myocardial damage and multiple organ failure (5, 6) . Overall, these results have potential far-reaching significance for the treatment of COVID-19, justifying a deeper study of JAK inhibitors as a therapeutic strategy to attenuate the cytokine storm and downstream organ failure in this condition, while also indicating that individuals with DS should be considered a high-risk population during the COVID-19 pandemic.

While MBP did not induce measurable proliferation of B cells nor CD4 þ T cells, we observed the production of TNF-a, IFN-g and IL-10 by PBMC in response to incubation with MBP in the presence of sera from healthy controls as well as sera from MS patients.

While these models are invaluable for evaluating pathology and host responses to infection, parallel in vitro studies can be used to identify gene expression and signaling pathway changes that occur in infected cells to mediate pathogenesis. In this study, we compare the gene expression response of murine lung epithelial cells to infection by three respiratory viruses used in murine models: rhinovirus (serotype RV1B) in the family Picornaviridae, mouse hepatitis virus (MHV strain 1) in the family Coronaviridae, and influenza A virus (strain PR8) in the family Orthomyxoviridae. doi = 10.1371/journal.pone.0178408 id = cord-004685-qote5nx2 author = Vassão, R.

The virus replication in target cells, the antiviral state induced by interferon (IFN) and the expression of a monokine with procoagulant activity (PCA) have been implicated in the resistance/susceptibility of the genetic homogeneous or heterogeneous mouse populations to the MHV3 infection [t, 2, 4, 7, 17, 18, 23, 243 . For the study of the individual correlation between in vivo resistance and in vitro inhibition of virus replication by IFN gamma, peritoneal macrophages from Hm, Lm and F 2 segregants were collected without sacrificing the animals, which were infected with MHV3 a week later. This brings further support to our previous suggestion that one of the main mechanisms involved in the resistance of mice to the MHV3 infection is based on the ability of their macrophages to restrict the virus replication upon IFN gamma activation [10 13, 153 . doi = 10.1007/bf01310802 id = cord-261028-sxux2ujo author = Vatner, Ralph E. title = STING, DCs and the link between innate and adaptive tumor immunity date = 2017-12-20 keywords = IFN; cell; dna; sting summary = Dendritic cells (DCs) are a heterogeneous population of professional antigen-presenting cells (APCs) from hematopoietic origin that serve as a key link between the innate and adaptive immune systems, and are the lynchpin in generating anti-tumor immunity (Steinman and Idoyaga, 2010) . More recently, type I IFN production and signaling through the STING pathway has been identified as having an essential role in the development of anti-tumor immunity in response to tumor derived DNA. DNA sensing by STING is the upstream link that triggers type I IFN production by DCs and facilitates effective cross-priming of tumor specific CD8+ T cells. This DNA is likely derived from stressed and dying cancer cells, and is introduced into the DC cytosol through a yet unknown mechanism where it binds to cGAS, which initiates STING mediated type I IFN transcription (Fig. 2) . doi = 10.1016/j.molimm.2017.12.001 id = cord-007621-rapinodd author = Vidovic, Maria title = Induction and regulation of class II major histocompatibility complex mRNA expression in astrocytes by interferon-γ and tumor necrosis factor-α date = 2002-11-13 keywords = IFN; MHC; RNA; TNF summary = doi = 10.1016/0165-5728(90)90103-t id = cord-023417-by18aczt author = Vilhelmsson, M. title = The Malassezia sympodialis Allergen Mala s 11 with Sequence Similarity to Manganese Superoxide Dismutase Induces Maturation and Production of Inflammatory Cytokines in Human Dendritic Cells date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = We demonstrate that Cw6 þ psoriasis patients had significant CD8 þ T-cell IFN-g responses to peptides from K17 and M6 protein selected on the basis of sequence homology and predicted HLA-Cw*0602 binding.

J o u r n a l P r e -p r o o f Taking into account that Ct value has a correlation with the amount of RNA present in the samples, it was found that medians and IQR of SARS-CoV-2 viral titer was similar in asymptomatic (33.00, 29.00-37.00) and symptomatic (30, 27 .00-37.00) cases; and comparison between groups did not show difference (p=0.4373). As show our results, SARS-CoV-2 infection induced high IFN-γ expression in swabbed cells from upper airway; its expression was higher in symptomatic patients in comparison with asymptomatic individuals. Also, positive correlation between IFN-γ and TGF-β1 provided evidence of immune response control could determinate the asymptomatic presentation of SARS-CoV-2 infection. doi = 10.1016/j.clim.2020.108576 id = cord-353337-o302vxqm author = Visser, Linda J. title = Dissecting distinct proteolytic activities of FMDV L(pro) implicates cleavage and degradation of RLR signaling proteins, not its deISGylase/DUB activity, in type I interferon suppression date = 2020-07-15 keywords = EMCV; FMDV; IFN; RLR; TBK1 summary = To study the effects of L pro on the induction of type I IFN in picornavirus-infected cells, we used two previously generated recombinant viruses; EMCV-L Zn , which contains inactivating mutations in the zinc-finger domain of the Leader (i.e. EMCV''s RLR signaling antagonist) [1, 43, 44] , and EMCV-L pro , which was derived from EMCV-L Zn and additionally encodes FMDV L pro at the N-terminus of its polyprotein ( Fig 1A) [45].

Overall, these differential gene expression analyses in macrophages reveal similar host responses to the wild-type and DUBmut viruses that include activation of UPR pathways and proinflammatory genes, whereas a distinct transcriptional profile during infection with the EndoUmut virus is predominately defined by a focused, robust antiviral response. The results presented here, and from studies of the MERS-CoV dORF3-5 mutant virus (26) Upon infection of a BMDM with EndoUmut, host double-stranded RNA (dsRNA) sensors (including MDA5, PKR, and OAS) are activated, resulting in robust transcription of type I IFN genes and rapid induction of apoptosis, the latter of which precludes the development of a potent inflammatory response. doi = 10.1128/jvi.00178-20 id = cord-323713-bc00vths author = Volpi, Stefano title = Efficacy and Adverse Events During Janus Kinase Inhibitor Treatment of SAVI Syndrome date = 2019-05-29 keywords = Fig; IFN; SAVI; patient summary = RESULTS: We identified three patients with SAVI presenting with skin involvement and progressive severe interstitial lung disease.

The intrinsic function of the cGAS-STING pathway facilitates type-I interferon (IFN) inflammatory signaling responses and other cellular processes such as autophagy, cell survival, senescence. In 2008, several research teams discovered a new protein on the endoplasmic reticulum (ER) which can be activated by immune-stimulatory DNA (ISD) and initiate type-I interferon (IFN) responses, which was named "stimulator of interferon genes" (STING, also known as MITA, ERIS) (2) (3) (4) .

For example, polymorphisms in host genes encoding proteins associated with regulation of an IFN response such as interferon receptor a-chain (IFNAR1) [10] , the IFN-inducible myxovirus resistance GTPase protein, Mx [11] , the IFN-inducible 2 0 ,5 0 -oligoadenylate synthetase (OAS) [12] and the suppressor of cytokine signaling (SOCS) 3 associated with regulation of an IFN response [13] , are predictive markers linked with the rate of sustained virological response (SVR) to HCV infection following IFN-a treatment. Remarkably, distinct highly pathogenic respiratory viruses, namely influenza viruses and the SARS-CoV, encode nonstructural proteins in their genomes that function as virulence factors that specifically target the host innate IFN response, further emphasizing the importance of IFNs as broad-spectrum antivirals. doi = 10.1016/j.it.2012.01.004 id = cord-252772-f3fctcru author = Wang, Changlin title = The Coronavirus PEDV Evades Type III Interferon Response Through the miR-30c-5p/SOCS1 Axis date = 2020-05-22 keywords = IFN; PEDV; SOCS1 summary = doi = 10.3389/fmicb.2020.01180 id = cord-333423-jhm7u8ka author = Wang, Dang title = Porcine Reproductive and Respiratory Syndrome Virus nsp11 Antagonizes Type I Interferon Signaling by Targeting IRF9 date = 2019-05-15 keywords = IFN; IRF9; PRRSV; STAT2; isgf3 summary = Furthermore, the nsp11-IRF9 interaction impaired the formation and nuclear translocation of the transcription factor complex IFN-stimulated gene factor 3 (ISGF3) in both nsp11-overexpressed and PRRSV-infected cells.

This provided further support for the notion that the ability of PRRSV nsp11 to block type I IFN signaling is independent of its endoribonuclease activity and cell cytotoxicity, because these three mutants had similar effects with respect to inhibiting the formation and nuclear translocation of ISGF3 compared with WT nsp11. doi = 10.1128/jvi.00623-19 id = cord-287874-wl0wlxh6 author = Wang, Ling title = Quadruple therapy for asymptomatic COVID-19 infection patients date = 2020-05-03 keywords = China; IFN; covid-19; patient summary = From 31 January 2020 to 10 February 2020, the patient was given quadruple therapy, including lopinavir/ritonavir tablets (400/100 mg every 12 h), arbidol tablets (0.2 g every 8 h), Lianhuaqingwen granules (a Chinese patent medicine, 6 g every 8 h) orally, and recombinant human interferon-α2b injection via aerosol (6.0 × 10 6 IU with 2 ml of sterilized water for injection every 12 h). • Quadruple therapy, which is lopinavir/ritonavir tablets, arbidol tablets, Lianhuaqingwen granules, and recombinant human interferon-α2b (IFN-α2b) injection via aerosol, is a common regimen for patients with COVID-19 in China.

Based on that background, we conducted a prospective randomized, controlled, open-label trial, to evaluate the efficacy and safety of oral leflunomide to treat hospitalized COVID-19 patients with prolonged post-symptomatic viral shedding. Fifty eligible patients were randomly assigned to a combination treatment group that received leflunomide (50 mg, q12h, three consecutive times, orally; then 20 mg, once a day for 8 days; a total course of 10 days) plus nebulized IFN -2a (3 million IU each time, adding 2 ml of sterilized water, atomization inhalation twice daily for 10 days), or to a control group that received nebulized IFN -2a This was an open-label, prospective randomized, controlled trial, which was conducted at East Campus, Renmin Hospital of Wuhan University. doi = 10.1093/cid/ciaa1417 id = cord-354730-hfau2odb author = Wang, Rong title = Antagonizing Interferon-Mediated Immune Response by Porcine Reproductive and Respiratory Syndrome Virus date = 2014-07-03 keywords = IFN; IRF3; PRRSV summary = PRRSV interplays with host IFN production and IFN-activated signaling, which may contribute to the delayed onset and low level of neutralizing antibodies, as well as weak cell-mediated immune response in infected pigs. This review summarizes the recent advances in the research of PRRSV interference with IFN-mediated innate immunity, the viral proteins involved, and their molecular mechanisms, as well as diverse effects by different strains and in different cell types. These transcription activation factors translocate into the nucleus and result in induction of type I IFNs and expression of inflammatory cytokines, which not only lead to an antiviral state of the neighboring uninfected cells, but also serve as key regulators to evoke adaptive immune response.

Furthermore, the recombinant feIFN-ωa and feIFN-ωb proteins demonstrated antiviral activity against VSV, feline coronavirus (FCoV), canine parvovirus (CPV), bovine viral diarrhea virus (BVDV), and porcine epidemic diarrhea virus (PEDV), indicating better broad-spectrum antiviral activity than the INTERCAT IFN. As shown in Figure 6 , the purified recombinant feIFN-ωa and feIFN-ωb proteins showed antiviral activity in both homologous animal cells (F81 cells) and heterologous animal cells (Vero, MDCK, MDBK, and PK-15 cells) in vitro. Our data showed that purified recombinant feIFN-ωa and feIFN-ωb had broad-spectrum antiviral activity in homologous and heterologous animal cells, suggesting they are candidates for the development of effective therapeutic agents to be used against viral infections in pet cats. doi = 10.3390/v12030335 id = cord-252671-uf96jgig author = Wang, Yi title = The Membrane Protein of Severe Acute Respiratory Syndrome Coronavirus Functions as a Novel Cytosolic Pathogen-Associated Molecular Pattern To Promote Beta Interferon Induction via a Toll-Like-Receptor-Related TRAF3-Independent Mechanism date = 2016-02-09 keywords = Fig; IFN-; SARS summary = doi = 10.1128/mbio.01872-15 id = cord-266914-3eatplc2 author = Wang, Yongjin title = Nsp1 proteins of group I and SARS coronaviruses share structural and functional similarities date = 2010-06-02 keywords = IFN; NL63; SARS summary = doi = 10.1016/j.meegid.2010.05.014 id = cord-273050-reez33md author = Wang, Zhenling title = Type I IFN deficiency: an immunological characteristic of severe COVID-19 patients date = 2020-09-14 keywords = IFN; covid-19 summary = reported that type I interferon (IFN) deficiency, could be a hallmark of severe coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Compared with patients that had mild-to-moderate infection, the ISG score (based on the mean expression value of six ISGs defining a type I IFN signature) was significantly reduced in critical patients. By correlated analysis of viral loading with IFN-α production either on protein or on gene level, the authors suggest that the most severe cases of COVID-19 are featured by impaired IFN-α production. To further explore the transcription factors that may cause the excessive inflammatory response of COVID-19, the authors observed that upregulated genes in severe or critical patients mainly belonged to the NF-κB pathway by a kinetic analysis. Impaired type I IFN response featured immunological characteristics of severe COVID-19 patients, accompanied by lymphocytopenia, hypercytokinaemia, and high blood viral load.

IFITM protein expression induced by type I IFN inhibits infection of many RNA viruses [22] [23] [24] [25] [26] [27] [28] [29] [30] . Therefore, we analyzed induction of IFITM1, 2 and 3 expression by IFN-b treatment in human keratinocytes, the natural host cells for HPV. To determine the effect of IFITMs on HPV16 entry, HeLa cells stably expressing c-Myc-tagged IFITM1, 2 or 3 or with vector alone ( Fig. 2A-B) were infected with HPV16-LucF. Using various epithelial cell lines and primary keratinocytes expressing IFITMs, we show that HPV infection is surprisingly enhanced by IFITM1 and IFITM3 overexpression (Fig. 2) . Taken together, our results suggest that HPV and other DNA viruses may have evolved to avoid IFITM1, 2 and 3 restriction during entry into host cells. doi = 10.1371/journal.pone.0096579 id = cord-328947-3l9ydspz author = Webb, L.

The lack of cGAS degradation seen in the exogenous expression system when compared to the infected cells shows that although there is a clear interaction of cGAS with nsP4, the degradation of cGAS observed is not mediated by the non-structural proteins of CHIKV, but must require other viral or host factors. Chikungunya virus inhibits DNA sensing by degrading cGAS both mock and infected cells by 4 hpi suggesting that the stress produced during the process of infection (mock or CHIKV) in HFF-1s stimulates increased translation at early timepoints ( Fig 4D, lanes 2 and 5) . doi = 10.1371/journal.ppat.1008999 id = cord-280130-ewqe9edq author = Weber, Friedemann title = Viral suppression of the interferon system date = 2007-01-27 keywords = IFN; RNA; virus summary = In most nucleated body cells, viral infections activate transcription of the ''''classic'''' IFN-b gene [1] by a signaling chain which is initiated by the RNA sensors RIG-I and MDA-5, which in turn act trough the adaptor IPS-1 and the kinases TBK-1 and IKK-3 to activate the transcription factor IRF-3 (see reviews by P.

To investigate the antiviral effects in immune cells, we first assessed the replication of divergent GFP-expressing viruses that were treated or untreated with cytotoxic-free (data not shown) Angelica tenuissima Nakai in RAW264.7 cells. These results suggest that the aqueous extract of Angelica tenuissima Nakai can induce the secretion of IFNs and pro-inflammatory cytokines, which can stimulate the cellular antiviral state for inhibition of viral replication. The aqueous extract of Angelica tenuissima Nakai inhibit the diverse viral infection through the induction of Type I IFN signaling and pro-inflammatory cytokines, leading to an antiviral state in epithelial and immune cells. doi = 10.1007/s12275-016-5555-4 id = cord-023389-ilrp8vb7 author = Wefer, J. title = Protective DNA Vaccination Against MOG(91‐108)‐Induced Experimental Autoimmune Encephalomyelitis Involves Induction of IFNβ date = 2008-06-28 keywords = CD8; IFN; IL-12; MBL; TNF; cell; dna summary = doi = 10.1111/j.0300-9475.2004.01423j.x id = cord-007646-yh8zi1ee author = Weiss, R.C. title = Effect of recombinant human interferon-alpha in vitro and in vivo on mitogen-induced lymphocyte blastogenesis in cats() date = 2002-11-12 keywords = IFN; PBL summary = The effect of recombinant human interferon-alpha (rHuIFN-α) in vitro and in vivo on mitogen-induced lymphocyte blastogenesis was evaluated in specific-pathogen-free cats. Pre-incubation of isolated feline peripheral blood lymphocytes (PBL) in vitro with either 104 or 103 International Units (U) of rHuIFN-o~ for 24 h significantly suppressed (P < 0.001 and 0.01, respectively) blastogenic responses to the phytomitogens concanavalin A (Con A) and pokeweed mitogen (PWM).

These data indicate that JHMV is capable of infecting glial cells generated from neural progenitor cells and that IFN-γ-mediated control of viral replication is dependent, in part, on type I IFN secretion. In the present study, we demonstrate that primary cultures of glia derived from neural progenitor cells are susceptible to JHMV infection and support viral replication. Therefore, these findings provide, to our knowledge, the first demonstration that glia-committed cells derived from neural precursors are susceptible to JHMV infection as well as identify a potential mechanism responsible for controlling viral replication. These findings indicate that differentiated cells derived from neural progenitors are susceptible to JHMV infection and are capable of supporting replicating virus which results in extensive cytopathology. doi = 10.1016/j.virol.2008.10.036 id = cord-021872-rhi7hi9m author = Wilkes, Rebecca P. title = Update on Antiviral Therapies date = 2015-12-04 keywords = FHV-1; FIV; HIV; IFN; cat; feline summary = Topical antiviral therapy has been mainly used for herpetic ocular disease, but studies have evaluated a systemic antiviral compound (famciclovir) for treatment of multiple clinical syndromes associated with FHV-1 infections. 7 A related drug, (R)-9-(2-phosphonylmethoxypropyl)-2,6diaminopurine (PMPDAP), has been shown previously to be a potent inhibitor of FIV replication in cell culture and has reduced the viral load in three of four cats experimentally infected with FIV when treated at 20 mg/kg SC three times per week for 6 weeks. 1 A prodrug of acyclovir, valacyclovir, was developed for increased bioavailability in humans, but use for FHV-1 treatment in experimentally infected cats induced fatal renal and hepatic necrosis and bone marrow suppression, and did not reduce viral shedding or clinical disease severity. 20 Even though this study did not mimic how cats with natural infection would be treated, results from a clinical case study suggested this drug is likely effective for treatment of clinical cases, though it was not blinded and placebo controlled. doi = 10.1016/b978-0-323-22652-3.00007-4 id = cord-282947-3hgku2e4 author = Wong, Hui Hui title = Accessory proteins 8b and 8ab of severe acute respiratory syndrome coronavirus suppress the interferon signaling pathway by mediating ubiquitin-dependent rapid degradation of interferon regulatory factor 3 date = 2017-12-30 keywords = Fig; IFN; IRF3; SARS summary = title: Accessory proteins 8b and 8ab of severe acute respiratory syndrome coronavirus suppress the interferon signaling pathway by mediating ubiquitin-dependent rapid degradation of interferon regulatory factor 3 Through the construction of recombinant IBV expressing proteins 8a, 8b and 8ab encoded by SARS-CoV ORF8, we demonstrate that expression of 8b and 8ab enables the corresponding recombinant viruses to partially overcome the inhibitory actions of IFN activation to achieve higher replication efficiencies in cells. Compared to wild type and rIBV8a/b, however, rIBV8b and rIBV8ab were observed to replicate significantly better and express higher levels of N protein in cells stimulated by poly (I:C) (Fig. 2a) . In view of the central role of IRF3 in regulating IFN activation during virus infection, 8b and 8ab with Flag epitope-tagged to their Ntermini were co-expressed with Myc-tagged IRF3 (Fig. 3a) in Cos-7 cells using the vaccinia/T7 expression system (Anderson et al., 1996; Lim and Liu, 2001) for co-immunoprecipitation assays to determine if there is any physical interaction between the proteins. doi = 10.1016/j.virol.2017.12.028 id = cord-319501-a2x1hvkk author = Wong, Lok-Yin Roy title = A molecular arms race between host innate antiviral response and emerging human coronaviruses date = 2016-01-15 keywords = IFN; MERS; RNA; SARS; rig summary = Particularly, the host pathogen recognition receptors and the signal transduction pathways to mount an effective antiviral response against SARS and MERS coronavirus infection are discussed.

First, we briefly discuss the signaling triggered by the retinoic acid-inducible gene 1-like receptor (RLR) and the Toll-like receptor (TLR), which leads to type I IFN synthesis and IFN-mediated signaling pathway activation, resulting in the expression of a variety of effector ISGs. We also summarize the strategies that HCV uses to escape IFN antiviral surveillance. 156 demonstrated that HCVinduced SG formation is IFN-and PKR-dependent and is inversely correlated with the induction of ISG proteins, such as myxovirus resistance gene A (MxA) and Ub-like (UBL)specific protease 18 (USP18), in HCV-infected cells without affecting the mRNA levels of these ISGs. Furthermore, the SG proteins TIA-1, TIAR and G3BP1 have been shown to play a critical role in HCV replication and infectious virus production. doi = 10.1038/cmi.2014.127 id = cord-306533-lvm11o4r author = Woo, Bean title = Regulatory interplay between deubiquitinating enzymes and cytokines date = 2019-06-08 keywords = HEK293; IFN; USP25; dub; rig summary = DUBs interact with some of the key molecules in the IFN signaling pathway, which include, but are not limited to, RIG-I, stimulator of interferon genes (STING), tumor necrosis factor receptor-associated factors (TRAFs), interferon regulatory factor are summarized in Table 1 .

Besides controlling virus replication, potential targets for drug development include controlling virus-induced host immune responses such as the recently suggested involvement of innate lymphoid cells and NADPH oxidases in influenza virus pathogenesis and immune cell metabolism. A recent study using RNAi also demonstrated that cholesterol homeostasis can be regulated via acid phosphatase 2 (ACP2)-mediated Niemann-Pick C2 activity and impaired the membrane fusion of IAV and influenza B virus (IBV) (52) , further suggesting the importance of controlling cholesterol homeostasis in the release of viral genome to cytoplasm. Furthermore, FPR2 antagonists have been described to possess antiviral activity against not only IAV but also IBV infection (111) , promoting the idea that antagonizing FPR2 to suppress Raf/MEK/ERK signaling cascade could potentially be a novel approach for the treatment of a broad spectrum of influenza viruses. doi = 10.3389/fimmu.2018.01547 id = cord-252485-cxi3cr15 author = Yoshida, Asuka title = IFN-β-inducing, unusual viral RNA species produced by paramyxovirus infection accumulated into distinct cytoplasmic structures in an RNA-type-dependent manner date = 2015-08-04 keywords = IFN; RNA; figure; rig summary = doi = 10.3389/fmicb.2015.00804 id = cord-002238-fyztb8d9 author = Young, D.

In addition to remdesivir, lopinavir, and chloroquine, our primary screening additionally identified types I and II recombinant interferons, 25-hydroxycholesterol, and AM580 as the most potent anti-SARS-CoV-2 agents among the 22 antiviral agents. In this primary screening, chloroquine, lopinavir, and remdesivir which were recently reported to have anti-SARS-CoV-2 activity, exhibited about 1.3-2.0 log10 copies/mL reduction in viral RNA load ( Figure 1 ). In comparison, recombinant IFN-β demonstrated the most potent anti-SARS-CoV-2 activity, with Avonex (IFN-β1a), Rebif (IFN-β1a), and Betaferon (IFN-β1b) each achieving about 3 log10 copies/mL reduction in viral load. In our primary screening using a fixed antiviral agent concentration and virus inoculum, we identified recombinant IFNs and lipogenesis modulators to be the most potent anti-SARS-CoV-2 agents among 22 broad-spectrum antivirals. doi = 10.3390/v12060628 id = cord-263141-n200x6z1 author = Zelaya, Hortensia title = Respiratory Antiviral Immunity and Immunobiotics: Beneficial Effects on Inflammation-Coagulation Interaction during Influenza Virus Infection date = 2016-12-23 keywords = IFN; ifv; respiratory summary = doi = 10.3389/fimmu.2016.00633 id = cord-256816-gd7y3ggj author = Zhang, Can title = Grass carp reovirus VP56 represses interferon production by degrading phosphorylated IRF7 date = 2020-02-04 keywords = GCRV; IFN; IRF7; VP56 summary = doi = 10.1016/j.fsi.2020.02.004 id = cord-324674-yd7idp90 author = Zhang, Chengfei title = IFN-stimulated P2Y(13) protects mice from viral infection by suppressing the cAMP/EPAC1 signaling pathway date = 2018-08-22 keywords = ADP; IFN; VSV; p2y summary = doi = 10.1093/jmcb/mjy045 id = cord-299549-bjqwwzam author = Zhang, Lei title = Against Ebola: type I interferon guard risk and mesenchymal stromal cell combat sepsis date = 2015-01-01 keywords = Ebola; IFN; virus summary = When the viral infection proceeds to the terminal stage, the key factor would be applying a non-specific immune modulation approach to suppress the cytokine storm that causes multiple organ failure, in an attempt to open a time window for the host''s immune system to recover. In most patients, Ebola viral burden elevates by time and triggers an extremely strong immune attack-a phenomenon called ''cytokine storm'' (Sullivan et al., 2003) , during which monocytes and/or macrophages produce a massive amount of pro-inflammatory cytokines, including tumor necrosis factor-α (TNF-α) and interleukins (ILs), and The virus burden, inflammatory response, and specific antibodies are the main contributors to different outcomes: mortality, survival, or symptomless infection (Fig. 2) , suggesting that the appropriate intervention strategy in each stage would accordingly be able to control the Ebola virus. Nonetheless, this phenomenon does give clues to the treatment against Ebola virus disease (EVD)-early activated innate immune responses may prevent the viral infection. doi = 10.1631/jzus.b1400365 id = cord-322683-wkrj6n1d author = Zhang, Pengfei title = Cellular Poly(C) Binding Protein 2 Interacts with porcine epidemic diarrhea virus Papain-Like Protease 1 and Supports Viral Replication date = 2020-07-13 keywords = IFN; PCBP2; PEDV; PLP1 summary = title: Cellular Poly(C) Binding Protein 2 Interacts with porcine epidemic diarrhea virus Papain-Like Protease 1 and Supports Viral Replication Taken together, these data demonstrated that PLP1 negatively regulated the production of type 1 interferon by interacting with PCBP2 and promoted PEDV replication. The PEDV N protein interacts with the TANK-binding kinase, blocking its association with interferon regulatory factor 3 (IRF3) and thus inhibiting IRF3 activation and type I IFN production (Ding et al., 2014; Hu et al., 2018) . PCBP2 expression is induced following viral infection and acts as a negative regulator of mitochondrial antiviral signaling protein (MAVS), triggering its degradation (You et al., 2009) . Although significant progress has been made in understanding PEDV evasion of innate immune responses, the mechanism of interaction between viral and host cell proteins remains unclear. In the present study, we demonstrated that PLP1 interacted with PCBP2 to inhibit IFN-β production and promote PEDV replication. doi = 10.1016/j.vetmic.2020.108793 id = cord-255773-b4re5bky author = Zhang, Qingzhan title = Suppression of type I interferon production by porcine epidemic diarrhea virus and degradation of CREB-binding protein by nsp1 date = 2016-01-14 keywords = CBP; Fig; IFN; IRF3; PEDV; cell summary = title: Suppression of type I interferon production by porcine epidemic diarrhea virus and degradation of CREB-binding protein by nsp1 We showed that PEDV suppressed the type I interferon production and ISGs expression in these cells, and identified nsp1, nsp3, nsp7, nsp14, nsp15, nsp16, E, M, N and ORF3 as the viral IFN antagonists.

A study published by our lab also demonstrated that nsp5, the 3C-like protease of porcine epidemic diarrhea virus (PEDV), which is classified into the Alphacoronavirus family, antagonizes IFN-β production by cleavage of NEMO . In this study, we reveal that nsp5 of PDCoV antagonizes the type I IFN signaling pathway through the cleavage of NEMO, a critical constituent of the IKK complex, thus representing a newly identified mechanism by which PDCoV evades the innate immune response. In contrast, TBK1induced activation of the IFN-β promoter was not affected by nsp5 (Fig. 3A) , suggesting that PDCoV nsp5 inhibits RIG-I/MDA5 signaling by targeting NEMO or other upstream proteins. doi = 10.1016/j.virol.2016.12.005 id = cord-300648-ixiam7qr author = Zhu, Xun title = IFITM3‐containing exosome as a novel mediator for anti‐viral response in dengue virus infection date = 2014-08-30 keywords = DENV-2; Fig; HUVEC; IFITM3; IFN; cell summary = At 24 h post infection when the infected cells were examined by real-time RT-PCR assay, strikingly, DENV-2 infection was suppressed potently by the IFITM3-containing exosomes in a dose-dependent manner in parental HeLa cells (Fig. 4A ) or in HeLa cells with endogenous IFITM3 knocked down (Fig. 4C) , and the copy number of DENV-2 viral RNA was reduced in the culture supernatant ( Fig. 4B and D), indicating that the observed antiviral effect was mediated by the exosome-transferred IFITM3. To verify that the enhanced antiviral effects caused by IFITM3-exosome transfer was a result of IFITM3 action rather than a stimulated paracrine IFNs response, the concentration of human IFN-α/β in culture supernatant of HeLa cells or HeLa-siIFITM3 cells treated with IFITM3laden exosomes was measured with ELISA by using Sendai virus (SeV; 100 HAU ml −1 ) as a positive stimulus control. doi = 10.1111/cmi.12339 id = cord-003239-nph2ezii author = Zhu, Zixiang title = Early Growth Response Gene-1 Suppresses Foot-and-Mouth Disease Virus Replication by Enhancing Type I Interferon Pathway Signal Transduction date = 2018-09-27 keywords = EGR1; FMDV; IFN; SAP summary = doi = 10.3389/fmicb.2018.02326 id = cord-007696-83v9yfa6 author = Zisman, David A. title = Pulmonary Fibrosis date = 2005 keywords = IFN; IPF; NSIP; UIP; fibrosis; idiopathic; patient; pulmonary summary = Idiopathic pulmonary fibrosis (IPF) is a chronic fibrosing lung disease limited to the lungs and associated with the histologic appearance of usual interstitial pneumonia (UIP) on surgical lung biopsy.

However plasma IL-6 estimation revealed a statistically significant reduction at 6 hours in tanrine-treated animals compared to glycino and TW controls ( Objective: To evaluate the effects of allogeneic blood transfusion, thermal injury and bacterial garage on interteukin 4 (IL-4), tumor necrosis factor alpha (TNF) production and host mortality and to study if the administration of thymopentth (THY) could affect these events. doi = 10.1007/bf02258437 id = cord-015147-h0o0yqv8 author = nan title = Oral Communications and Posters date = 2014-09-12 keywords = CIA; COX-2; Department; ELISA; IFN; IL-6; Institute; LPS; MIF; MPO; PAF; PCR; PGE2; TNF; University; cell; disease; effect; expression; increase; inflammation; inflammatory; level; model; mouse; response; result; study summary = Cyclooxygenases (COX) catalyze the first step in the synthesis of prostaglandins (PG) from arachidonic acid.COX-1 is constitutively expressed.The COX-2 gene is an immediate early-response gene that is induced by variety of mitogenic and inflammatory stimuli.Levels of COX-2 are increased in both inflamed and malignant tissues.In inflamed tissues, there is both pharmacological and genetic evidence that targeting COX-2 can either improve (e.g., osteoarthritis) or exacerbate symptoms (e.g., inflammatory bowel disease).Multiple lines of evidence suggest that COX-2 plays a significant role in carcinogenesis.The most specific data that support a cause-and effect relationship between COX-2 and tumorigenesis come from genetic studies.Overexpression of COX-2 has been observed to drive tumor formation whereas COX-2 deficiency protects against several tumor types.Selective COX-2 inhibitors protect against the formation and growth of experimental tumors.Moreover, selective COX-2 inhibitors are active in preventing colorectal adenomas in humans.Increased amounts of COX-2-derived PGE2 are found in both inflamed and neoplastic tissues.The fact that PGE2 can stimulate cell proliferation, inhibit apoptosis and induce angiogenesis fits with evidence that induction of COX-2 contributes to both wound healing and tumor growth.Taken together, it seems likely that COX-2 induction contributes to wound healing in response to injury but reduces the threshold for carcinogenesis. doi = 10.1007/bf03353884 id = cord-017184-1ewi3dka author = nan title = Primary Immunodeficiencies date = 2008 keywords = BMT; CD4; CD8; Fig; HLA; IFN; SCID; Table; cell; child; deficiency; infection; patient summary = In this disease, microorganism phagocytosis by polymorphonuclear (PMN) leukocytes appears annulled, and the patient is subject to severe infections supported by capsular bacteria: the deficiency, described in association with severe and recurrent infantile infections [175, 485, 487] , depends on the lack of mannose-binding lectin (MBL) [487] , its Primary Immunodeficiencies a possible atopy dependence on IgA underproduction rather than on IgE hyperproduction ( Fig. 4.1 ): in children with levels of IgA at the minimum normal level, and followed from birth until the age of 18-23 months, a greater severity of atopic manifestations and an increased cumulative incidence of asthma, AD and otitis media with effusion (OME) were observed compared to controls. doi = 10.1007/978-3-540-33395-1_22 id = cord-022888-dnsdg04n author = nan title = Poster Sessions date = 2009-08-19 keywords = APC; BCR; CD14; CD4; CD8; CMV; CTL; EBV; ELISA; Germany; HCV; HIV; HLA; IBD; IFN; IL-10; IL-2; IL-4; IL-6; Immunology; Institute; LPS; MHC; NKT; PCR; RNA; SLE; TCR; TGF; TLR; TLR4; TNF; University; antigen; cell; dna; expression; immune; mouse; patient; protein; response; result; study; th1; th2 summary = Methods: Phospho-specific Western blot analyses were performed to verify the functionality of the different IFN-g pathway components, intra-and extracellular flow cytometry experiments were employed to determine the expression of antigen processing components and HLA class I cell surface antigens, quantitative real time-PCR experiments to confirm the absence of JAK2 and presence of pathway relevant molecules as well as, genomic PCR and chromosome typing technique to prove the deletion of JAK2. In order to accomplish these objectives we induced priming or tolerance of ovalbumin (OVA 323-339 peptide)-specific T cells from DO11.10 TCR transgenic mice in vitro or, following adoptive transfer of near physiologically relevant numbers of such cells into recipients, in vivo and correlated functional outcome (via proliferation and cytokine readout assays or antibody production) with E3 ubiquitin-protein ligases expression and the ubiquitination status of the TCR signalling machinery. doi = 10.1002/eji.200990224 id = cord-023017-k6edtg58 author = nan title = AASLD Abstracts (pp. 282A–382A) date = 2006-02-10 keywords = CD4; CD8; HCC; HCV; HIV; HSC; IFN; MELD; OLT; PCR; RNA; SVR; alt; cell; conclusion; day; group; liver; method; patient; result; study summary = doi = 10.1002/hep.1840380505 id = cord-023033-tgt69ir6 author = nan title = Poster Session (pp. 78A–178A) date = 2006-02-10 keywords = CD4; CD8; HCV; HSC; IFN; LDLT; cell; liver; patient; result summary = Methods: We performed a retrospective analysis comparing outcomes, and the incidence, timing, and severity of histologic recurrence of HCV following transplantation in patients who underwent living donor liver transplant compared to recipients of cadaveric organs. Local liver immune responses are thought to play a major role in chronic autoimmune diseases directed at biliary epithelium.Using the apical sodium dependent bile acid transporter (ASBT) promoter to drive biliary epithelial cell -specific expression of a membrane form of ovalbumin (OVA), we have previously developed OVA-BIL transgenic mice. Thus, our AIM was to ascertain whether Kupffer cells express death ligands and contribute to hepatocyte apoptosis and liver fibrosis in the bile duct ligated mouse, an animal model of cholestasis. Control experiments confirmed that Y2 protein inhibited IFNa-induced ISRE-mediated signaling in Huh-T7 cells; relative luciferase activity was reduced from 653 (pH771 IFNP nAb increased HCV core Ag replication by 42% and 23% compared to no treatment (p=O.O1). doi = 10.1002/hep.1840380503 id = cord-023143-fcno330z author = nan title = Molecular aspects of viral immunity date = 2004-02-19 keywords = CD4; CD8; CNS; CTL; HIV; HIV-1; HLA; IFN; LCMV; MHC; cell; infection; mouse; protein; response; viral; virus summary = Based on a variety of experimental evidence, it is clear that demyelination induced in SJUJ mice by infection with the BeAn strain of TMEV is a Thl-mediated event: (a) disease induction is suppressed in T cell-deprived mice and by in vivo treatment with anti-I-A and anti-CD4 antibodies; (b) disease susceptibility correlates temporally with the development of TMEV-specific, MHC-class Il-restricted DTH responses and with a predominance of anti-viral lgG2a antibody; (c) activated (Le., lL-2RC) T cells infiltrating the CNS are exclusively of the CD4+ phenotype, and (d) proinflammatory cytokines (IFNq and TNF-p) are predominantly produced in the CNS. These results have important implications for a possible viral trigger in MS as they indicate that chronic demyelination in TMEV-infected mice is initiated in the absence of demonstrable neuroantigen-specific autoimmune responses and are consistent with a model wherein early myelin damage is mediated via primarily by mononuclear phagocytes recruited to the CNS and activated by pro-inflammatory cytokines produced by TMEV-specific Thl cells. doi = 10.1002/jcb.240591009 id = cord-023306-3gdfo6vd author = nan title = TSANZ Oral Abstracts date = 2010-03-01 keywords = Australia; COPD; GSH; IFN; IL-6; Nil; cell; lung; patient summary = Conflict of Interest No. Purpose We examined age trends in the distribution of stage at diagnosis in patients presenting with non-small cell lung cancer (NSCLC) at tertiary hospitals. Methods Eleven healthy male subjects, aged 28(8) (SD) years completed separate visits with (a) no restriction and (b) chest wall strapping to reduce FVC by 30 (7) Introduction Glossopharyngeal breathing (GPB) is used by competitive breath-hold divers to increase lung gas content above TLC to improve performance. Our DC culture results showed that both MHC-I and MHC-II expression on DCs from COPD were significantly down regulated compare to healthy controls, which could affect MHC restricted Ag presentation, and lead to a failure to activate responder T cells. doi = 10.1111/j.1440-1843.2010.01735.x id = cord-023443-pvz7dll9 author = nan title = Abstracts for the Scandinavian Society for Immunology 35th Annual Meeting and 20th Summer School date = 2004-06-02 keywords = CD8; IFN; IL-12; MBL; TNF; cell summary = We demonstrate that Cw6 þ psoriasis patients had significant CD8 þ T-cell IFN-g responses to peptides from K17 and M6 protein selected on the basis of sequence homology and predicted HLA-Cw*0602 binding. The uptake of MBP by B cells and the presentation of MBP-derive peptides to T helper (Th) cells by B cells may be promoted by the formation of complement (C) activating immune complexes (ICs) between MBP and natural autoantibodies in healthy individuals and disease-associated anti-MBP antibodies in MS patients, respectively. While MBP did not induce measurable proliferation of B cells nor CD4 þ T cells, we observed the production of TNF-a, IFN-g and IL-10 by PBMC in response to incubation with MBP in the presence of sera from healthy controls as well as sera from MS patients. In conclusion, the results of this study suggest an involvement of the ASMase in the activation, expansion or maturation of virus-specific CD8 þ T cells during the acute infection of mice with the LCM virus. doi = 10.1111/j.1365-3083.2004.01423.x id = cord-024651-578c9ut5 author = nan title = 2020 CIS Annual Meeting: Immune Deficiency & Dysregulation North American Conference date = 2020-05-11 keywords = ALPS; Abstract; Background; CD4; CD8; CGD; CVID; Case; EBV; GOF; HIES; HLH; HSCT; Hospital; IFN; IVIG; Immunology; National; PID; Report; SCID; STAT3; Text; cell; disease; figure; infection; introduction; mutation; patient; result summary = Abstract/Case Report Text Introduction: Mutations in the gene encoding signal transducer and activator of transcription 3 (STAT3) cause autosomal dominant hyperimmunoglobulin E syndrome (AD-HIES) characterized by recurrent skin and sinopulmonary infections, atopic dermatitis, and elevated serum immunoglobulin E (IgE) levels.
