Neutralization of influenza viruses by antibodies.

Neutralization of (red) influenza viruses by (blue) antibodies. I wanted "A globose influenza virus with 20 blue club-shaped hemagglutinin spikes and 10 red rod neuraminidase spikes on its surface...". But it resulted in a net of antibodies precipitating viruses in the extracellular environment. Antibodies cause virus particles to clump together. Virus neutralization is defined as the reduction in viral infectivity mediated by antibodies (neutralizing antibodies [NAbs]). By binding to the virions, NAbs block one or more steps of the viral replication cycle, and/or cause aggregation or lysis of virus particles, thus neutralizing or reducing virus infectivity (Klasse, 2014). Sorry for the txt length, but the image deserves it. Thank you.
