In short, we confirmed that although IRF3 is missing in chickens, they employ IRF7 to reconstitute corresponding IFN signaling to respond to both DNA and RNA viral infections.

These findings suggest that zebrafish RPZ5 is a negative regulator of phosphorylated IRF7 and attenuates IFN expression during viral infection, providing insight into the IFN balance mechanism in fish.<b>IMPORTANCE</b> The phosphorylation of IRF7 is helpful for host IFN production to defend against viral infection; thus, it is a potential target for viruses to mitigate the antiviral response.

After stimulation with polyinosinic-polycytidylic acid (poly I:C) (0.25 μg/ml) for 4 h to mimic viral infection, 293FT wild-type (WT) and IRF7-Δ7 cells were treated with 0, 1, or 100 μM nicotine for 24 h, which increased IFN-β expression in both types of cells but elevation was higher in WT cells (p < 0.001).

These data demonstrate that infection with influenza results in the reduced expression of transcription factor IRF7 in NECs from smokers, and that these effects may be mediated by an epigenetic modification of the IRF7 gene, thus providing a potential mechanism rendering smokers more susceptible to respiratory virus infections.

Our results indicate that infection with amplicons triggered an interferon (IFN)-regulatory factors 3 and 7 (IRF3/7)-dependent antiviral response, rendered the cells resistant to vesicular stomatitis virus infection and induced significant changes in the pattern of cellular gene expression, including the upregulation of Toll-like receptor 3 (TLR3), IRF7 and IFN-stimulated genes (ISGs).
