Scientists can now visualize these particles in high resolution, revealing the precise atomic structure of the proteins. Its structure allows it to bind to sialic acid receptors on the surface of human respiratory cells, a necessary first step for infection.
Drug Target Sites on the Flu Virus Shape
Unlike a simple sphere, the influenza virus exhibits a complex and pleomorphic structure, meaning its form is not uniform. This trimeric protein forms the primary spikes on the viral surface and acts as a molecular hook.
The data derived from these structural studies directly informs the design of therapeutics that can block the virus from entering or exiting host cells. For instance, the H1N1 and H3N2 subtypes of Influenza A have distinct antigenic properties due to the structure of their hemagglutinin heads.
Drug Target Sites on the Flu Virus Shape
These structural differences are why the immune system may recognize one strain but struggle against another, necessitating annual updates to the flu vaccine. Neuraminidase: The Release Mechanism Complementing hemagglutinin is neuraminidase, another transmembrane protein that forms mushroom-shaped spikes on the viral surface.
