We recently identified an essential linkage of stimulation of the inflammatory cytokine interleukin-1\u03b2 (IL-1\u03b2) and induction of ISGs that function as host restriction pathways against the emerging flavivirus West Nile virus (WNV)\n                    <jats:italic>in vivo<\/jats:italic>\n                    . Here we utilized\n                    <jats:italic>ex vivo<\/jats:italic>\n                    global transcriptome analysis of primary dendritic cells, known targets of WNV replication, to define gene signatures required for this IL-1\u03b2-driven antiviral response. Dendritic cells that were deficient in IL-1 receptor signaling showed dysregulation of cell-intrinsic defense genes and loss of viral control during WNV infection. Surprisingly, we found that in wild-type cells, IL-1\u03b2 treatment, in the absence of infection, drove the transcription of IFN-\u03b2 and ISGs at late times following treatment. Expression of these antiviral innate immune genes was dependent on the transcription factor IFN regulatory factor 3 (IRF3) and appears to reflect a general shift in IL-1\u03b2 signaling from an early inflammatory response to a late IFN-mediated response. These data demonstrate that inflammatory and antiviral signals integrate to control viral infection in myeloid cells through a process of IL-1\u03b2-to-IRF3 signaling crosstalk. Strategies to exploit these cytokines in the activation of host defense programs should be investigated as novel therapeutic approaches against individual pathogens.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>IMPORTANCE<\/jats:bold>\n                    West Nile virus is an emerging mosquito-borne flavivirus that can result in serious illness, neuropathology, and death in infected individuals. Currently, there are no vaccines or therapies for human use against West Nile virus. Immune control of West Nile virus infection requires inflammatory and antiviral responses, though the effect that each arm of this response has on the other is unclear. The significance of our research is in defining how virus-induced inflammatory responses regulate critical antiviral immune programs for effective control of West Nile virus infection. These data identify essential mechanisms of immune control that can inform therapeutic efforts against West Nile virus, with potential efficacy against other neuroinvasive viruses.\n
