Description: Caption:
This illustration depicted a 3D computer-generated rendering of a whole influenza (flu) virus, rendered in semi-transparent blue, atop a white background. A transparent area in the center of the image, revealed the viral ribonucleoproteins (RNPs) inside. The RNPS were shown in white with their coiled structures, and three-bulbed polymerase complex on the ends. An influenza virus’ RNP is composed of both RNA and protein. Every influenza virus has eight RNP segments that correspond to the virus’ eight total gene segments. Three of these RNP segments encode the virus’ surface proteins, i.e., the HA, NA and M proteins. The virus’ hemagglutinin (HA) and neuraminidase (NA) surface proteins were displayed in semi-transparent blue, sticking out of the surface of the virus. 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.
