    Snippet: While the past decade yielded many exciting insights into regulation of enteric viruses by IFN-λ, many important questions remain. Type I and III IFNs share significant overlap in induction and signaling pathways, though there are distinctions in promoter sequences, upstream regulatory elements, and kinetics of downstream gene stimulation [reviewed in Ref. (76) ]. However, most previous studies were performed in vitro outside of the complex envi.....
    Document: While the past decade yielded many exciting insights into regulation of enteric viruses by IFN-λ, many important questions remain. Type I and III IFNs share significant overlap in induction and signaling pathways, though there are distinctions in promoter sequences, upstream regulatory elements, and kinetics of downstream gene stimulation [reviewed in Ref. (76) ]. However, most previous studies were performed in vitro outside of the complex environment of the gut. How is IFN-λ production regulated in the intestine, and by what pathways is it induced in vivo by viral infection? Are specific ISGs induced by IFN-λ necessary for antiviral activity against enteric infections? Conversely, viruses rapidly evolve mechanisms to evade the host immune system. Are there viral factors that specifically target IFN-λ induction or signaling pathways for evasion or suppression?
