WebUna de las formas en que los virus de la influenza cambian se denomina "variación antigénica". Las variaciones consisten en pequeños cambios (o mutaciones) en los genes de los virus de la influenza que pueden dar lugar a cambios en las proteínas de la superficie del virus, HA (hemaglutinina) y NA (neuraminidasa). WebHemagglutinin (HA) or Haemagglutinin (BE) is an antigenic glycoprotein found on the surface of the influenza viruses. It is responsible for binding the virus to the cell that is being infected. The name "hemagglutinin" comes from the protein's ability to cause red blood cells (erythrocytes) to clump together ("agglutinate") in vitro.
