Pathogen recognition is not only an essential component of the innate immune response against infection, but also plays an important role in bridging the innate and adaptive systems by Toll-like receptors (TLR) activation of antigen presenting cells by up-regulation of major histocompatibility complex (MHC) and co-stimulatory molecules (75) . Current evidence is only limited to in vitro TLR2/4 stimulation studies using placental explants and primary first trimester trophoblast cells, which drives the expression of FIGURE 3 | Toll-like receptors and potential inflammatory response at the decidua. In the mouse model of ZIKV infection, type I IFN-mediated signaling is essential for the control of viral replication in the placenta, but can also lead to significant placental pathology and fetal mortality (116, 117) . ./cache/cord-312438-zr9zx7pv.txt ./txt/cord-312438-zr9zx7pv.txt
