The importance of influenza viruses as worldwide pathogens in
humans, domestic animals, and poultry is well recognized. Discerning how influenza viruses interact with the host at a cellular level is
crucial for a better understanding of viral pathogenesis. Influenza viruses induce apoptosis through mechanisms involving the interplay of
cellular and viral factors that may depend on the cell type. However,
it is unclear which viral genes induce apoptosis. In these studies, we
show that the expression of the nonstructural (NS) gene of influenza A
virus is sufficient to induce apoptosis in MDCK and HeLa cells. Further
studies showed that the multimerization domain of the NS1 protein but
not the effector domain is required for apoptosis. However, this
mutation is not sufficient to inhibit apoptosis using whole virus.
