H1N1 flu virus particles. Illustration of two H1N1 influenza A (flu) virus particles (virions). In each particle's lipid envelope are two types of protein spike, haemagglutinin (H) and neuraminidase (N), which determine the strain of virus. These are used for recognising and binding to the host cell. Across bottom is a lipid bilayer representing the cell membrane. | |
