This trimeric protein forms the primary spikes on the viral surface and acts as a molecular hook. This enzymatic action prevents the newly formed viruses from sticking to each other or the host, allowing them to spread efficiently to infect other cells.

Neuraminidase: The Release Mechanism Complementing hemagglutinin is neuraminidase, another transmembrane protein that forms mushroom-shaped spikes on the viral surface. Embedded within this fatty layer are the glycoproteins hemagglutinin (HA) and neuraminidase (NA), which are crucial for attachment to host cells and the release of new viral particles.
Scientists can now visualize these particles in high resolution, revealing the precise atomic structure of the proteins. Once new viral particles are assembled inside a host cell, neuraminidase cleaves sialic acid residues from the host cell surface and the mucus layer of the respiratory tract.

Its structure allows it to bind to sialic acid receptors on the surface of human respiratory cells, a necessary first step for infection. The flu virus shape is a critical feature that dictates how the virus functions, spreads, and interacts with the human immune system.
