    Snippet: Identifying viral antagonists of host pathways can highlight critical antiviral host pathways. MNoV antagonizes IFNs via a protein expressed from ORF4, VF1, which in vitro delays upregulation of innate genes including type I IFNs (69) . MNoV has also been shown to diminish the host response to infection via its protease NS6, which specifically suppresses host ISG translation (70) .

    Document: Identifying viral antagonists of host pathways can highlight critical antiviral host pathways. MNoV antagonizes IFNs via a protein expressed from ORF4, VF1, which in vitro delays upregulation of innate genes including type I IFNs (69) . MNoV has also been shown to diminish the host response to infection via its protease NS6, which specifically suppresses host ISG translation (70) . However, the interactions of these genes with IFN-λ signaling in the intestine have not yet been explored. A final potential viral player of interest is MNoV NS1/2. A single amino acid difference in this gene confers the ability of the virus to persist in the intestine and stool (65) . It is a tempting speculation that intestinal viral persistence requires antagonism of IFN-λ, but further studies are needed to determine whether NoV has evolved to avoid the antiviral effects of this signaling pathway.
