Caption

3D computer-generated rendering of a whole influenza (flu) virus. Our immune response is triggered by the virus' hemagglutinin (HA) and neuraminidase (NA) surface proteins, shown in semi-transparent blue. HA is a trimer comprised of three subunits, while NA is a tetramer, comprised of four subunits, with a head region resembling a 4-leaf clover.
