Web11 apr. 2024 · Moreover, the influenza virus binds to the host via hemagglutinin. Neuraminidase is the other best-characterized protein in the genome. Both are glycoproteins. Depending on the type of ribonucleoprotein, there are three species of influenza; they are influenza A, B, and C. Influenza A causes most pandemics. WebIn order to characterize the virus-host cell interactions, ... Antibodies CR8033 and CR8071 recognize distinct conserved epitopes in the head region of the influenza B hemagglutinin (HA), whereas CR9114 binds a conserved epitope in the HA stem and protects against lethal challenge with influenza A and B viruses.
