hemagglutinin and neuraminidase. There are 16 different hemagglutinins and nine different neuraminidases, and reassortment of these two antigens determines the influenza A virus subtype (e.g ...

three subtypes of hemagglutinin (H1, H2, and H3) and two subtypes of neuraminidase (N1 and N2) have caused sustained epidemics in the human population. Birds are hosts for all influenza A subtypes ...

Duke researchers have opened a new avenue in the attack against influenza ... HA), is hemagglutinin, a lollipop-shaped protein that binds to a receptor on a human cell, the first step toward getting ...

The heads of countless hemagglutinin proteins are arrayed on the surface portion of the virus along with another mushroom-shaped influenza protein: neuraminidase. During the process of infection ...

Influenza vaccine efficacy studies entail ... which allow a more granular view of the hemagglutinin and neuraminidase genes, or even the entire genome.NGS can provide insight, including ...

Previous exposures to older flu strains prime the immune system to produce antibodies against bird flu (H5N1).

Influenza A is divided into subtypes based on two proteins on the virus's surface: hemagglutinin and neuraminidase. These lead to different combinations—with H1N1 and H3N2 presently the most ...
