Our laboratory investigates the roles of virus-host interactions in replication and pathogenesis. We study RNA viruses, including hepatitis C virus, dengue virus, Zika virus, and noroviruses. These are medically important viruses, causing cirrhosis/liver cancer, hemorrhagic fever, birth defects, and severe GI disease, respectively.
We have identified ~100 host cofactors of viral replication. We now study the importance of these cellular genes in diverse steps of the viral life cycle, including entry, the regulation of viral protein translation and RNA replication, modulation of cellular lipid metabolism, the establishment of viral replication complexes, the secretion of infectious virus, and control of infection by the innate immune system.
