Abstract

Norovirus is an enteric virus that infects intestinal epithelial tuft cells in mice. Lee et al. discover that murine norovirus NS1 is an unconventionally secreted protein that overcomes IFN-λ-mediated norovirus control and is critical for intestinal infection in mice. Additionally, vaccination with NS1 alone confers protection, suggesting potential vaccine strategies.
