Outline of Final Research Achievements |
By focusing on a novel antiviral function (budding inhibition), we found potential roles of anti-hemagglutinin antibodies in cross-protective immunity against influenza A viruses with multiple HA subtypes. It was particularly noted that the comparison between IgG and IgA antibodies recognizing the same epitope on the HA molecule clearly demonstrated the greater potential of HA-specific IgA than IgG antibodies in antiviral activities. It was also attempted to modify antibody specificity by structure-based molecular simulation and production of recombinant antibodies.
