Research Abstract

To elucidate the mechanism of H5N1 pathogenesis, we prepared primary airway epithelial cells from alveolar tissues from 1-year-old pigs and generated recombinant H5N3 viruses possessing H5N1 hemagglutinin (HA) by using reverse genetics system. After infection with the recombinant H5N3 viruses, H5N1 HA protein played a critical role in inducing caspase-dependent apoptosis in infected porcine alveolar epithelial cells. In addition, H5N1 HA1 region (84-340 amino acids) was essential for induction of caspase-dependent apoptosis in infected cells.
