Rhesus rotavirus NSP1 mediates extra-intestinal infection and is a contributing factor for biliary obstruction.

ABSTRACT: We previously demonstrated that in Ifnar1-/-Ifngr1-/- or Stat1-/- suckling mice lacking intact type I and type II interferon (IFN) signaling, rhesus rotavirus (RRV) infection causes a lethal disease with clinical manifestations similar to biliary atresia, including acholic stools, oily fur, growth retardation, and excess mortality. Elevated levels of viral RNA are detected in the bile ducts and liver of diseased pups together with severe inflammatory responses in these tissues. However, the viral determinants and the molecular mechanisms driving this process remain incompletely understood. Using an optimized rotavirus (RV) reverse genetics system, we generated a panel of recombinant RVs that encode non-structural protein 1 (NSP1) derived from different RV strains. We found that compared to
