| Outline of Final Research Achievements |
Proteolytic activation of influenza virus hemagglutinin by the proteases, including type II transmembrane serine proteases which are expressed in the airway epithelial cells, enhances viral entry into cytoplasm, resulting in the next steps of viral replication. Viral replication, the release of inflammatory cytokine and cell damage are associated with symptoms, including fever and exacerbation of bronchial asthma. Because serine protease inhibitors reduce influenza viral replication by the inhibition of entry into cytoplasm, cytokine release and cell damage, the inhibitors are new potential candidate drugs for influenza virus infection-induced asthma exacerbation.
