Outline of Final Research Achievements

Avian influenza viruses (IV) infect host cells by binding to Siaα2-3Gal using virus hemagglutinin (HA). However, it is reported that glycan binding preferences were different between HA from duck IV, which is not pathogenic to the natural host, and HA from chicken IV. These HAs discriminate the glycan structures attaching to Siaα2-3Gal, such as Siaα2-3Galβ1-3GalNAc or Siaα2-3Galβ1-4(Fucα1-3)GlcNAc. These differences of HAs might be generated by adopting specific glycan structures expressed on host cells of different species through the virus infection, growth and accumulated mutations. The differences of glycan structures among these avian species have not been studied well, although glycan structures of them are potentially different from those of mammals. Thus, we tried to establish the method to analyze glycan structures from avian tissues using HPLC and mass spectrometric analysis.
