Outline of Final Research Achievements |
The purpose of this study was to reveal the mechanisms responsible for the difference in infectivity between the current H5N1 and previously circulating avian influenza viruses. Current H5N1 has a broader tropism for human respiratory epithelial cell clones with different membrane fusion activity compared with previously circulating strains. The endosomal environment of high-susceptibility cell clones is different from that of low-susceptibility cell clones. Avian influenza virus infection of human respiratory epithelial cells depends on both viral membrane fusion activity and host endosomal environment.
