In this study, we assessed MERS-CoV replication as well as induction of inflammatory cytokines and chemokines in MDMs and immature and mature MDDCs. Immature MDDCs and MDMs were permissive for MERS-CoV infection, while mature MDDCs were not, with stimulation of proinflammatory cytokine and chemokine upregulation in MDMs, but not in MDDCs. To further evaluate the antiviral activity of well-defined drugs in primary antigen presenting cells (APCs), three compounds (chloroquine, chlorpromazine and toremifine), each with broad-spectrum antiviral activity in immortalized cell lines, were evaluated in MDMs and MDDCs to determine their antiviral effect on MERS-CoV infection. However, MERS-CoV continued to propagate in immature MDDCs up to 8 days pi, demonstrating differential infection and replication capabilities in MDMs and immature MDDCs. To compare the ability of MERS-CoV to induce innate immune responses in three types of APCs, the release of cytokines and chemokines was measured from virus-or mock-infected cells.	./cache/cord-349781-l93978vq.txt	./txt/cord-349781-l93978vq.txt
