FLU virus particle: graphic of influenza virion

Above: surface view illustration of influenza virus or virion (virus particle). Image measures 500 pixels across, original image is 2160 pixels across.

EXPLANATION OF PICTURE:

In this graphic, the red spikes represent Haemagglutinin and are arranged all over the surface, roughly equally spaced. The yellow box like surface features represent Neuramindase. Each 4-fold assembly is a single tetramer of Neuraminidase. The Neuraminidase tetramers are not distributed evenly over the virus but cluster in groups. The green surface peeping through between the spikes represents the viral envelope, which was derived from the host cell during budding.
