Several new cases of measles have been detected at a detention center in southern New Mexico. The New Mexico Department of ...

Long Island’s last commercial duck farm is rebuilding after a bird flu outbreak forced the destruction of its entire ...

While current influenza vaccines primarily target the variable hemagglutinin protein, the slower-evolving neuraminidase presents a promising target for the development of new vaccines providing ...

Seasonal vaccination had been the main method for preventing human influenza, with licensed vaccines regularly updated for viral mutations and standardized for haemagglutinin content, though their ...

Polybasic amino acid residues at the hemagglutinin (HA) cleavage site are insufficient to induce the highly pathogenic phenotype of avian influenza viruses in chickens. In our previous study, an H7N7 ...

The hemagglutinin helps the virus attach itself to a cell to infect it, and the neuraminidase releases the virus to allow it to infect other cells.

Two proteins, the hemagglutinin and the neuraminidase, protrude from the surface of the influenza virus. Their detection by the immune system allows the host organism to mount defences against the ...

As there are more hemagglutinin than neuraminidase molecules on the flu virus surface, the team focused their efforts on identifying regions of that protein that were less likely to mutate over time.

The N is neuraminidase, a second protein that enables a newly made virus to escape the host cell and go on to infect other cells. “On the virus particle, there's five to 10 times more hemagglutinin ...

It comprises hemagglutinin and neuraminidase surface antigens purified from inactivated A/turkey/Turkey/1/2005 (H5N1)-like strain (NIBRG 23) viruses produced in MDCK cell cultures, along with the ...
