If this occurs, H5N1 could potentially start spreading from human to human. Influenza viruses are covered with two lollipop-shaped proteins called hemagglutinin and neuraminidase, for which the ...

A collaborative effort between The Wistar Institute, University of Pennsylvania, and INOVIO Pharmaceuticals has led to an ...

The stem is genetically stable across influenza viral strains. Picture hemagglutinin's shape as a submicroscopic mushroom, a ...

Very few humans have gone up against bird flu. But we've all dealt with seasonal flu for years. Some of our immune systems ...

H5N1 influenza is evolving rapidly, weakening the effectiveness of existing antibodies and increasing its potential threat to ...

Influenza strains are referred to by a shorthand code, H5N1 for example, that describes which flavors of two particular surface proteins it carries. The H (sometimes HA), is hemagglutinin, a ...

The isolation of influenza virus 80 years ago in 1933 ... for viruses isolated during the 1900s); The subtype [16 possible hemagglutinin and 9 possible neuraminidase subtypes].

Two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA), and the M2 ion-channel protein are embedded in the viral envelope, which is derived from the host's plasma membrane.

Yoshi Kawaoka: H5N1 is a subtype of influenza A virus known for primarily infecting birds. It’s called H5N1 because of two surface glycoproteins on the virus. Hemagglutinin — H, and ...

Through this investigation, Reid was able to map a gene called the hemagglutinin, which is key to allowing the influenza virus to take hold. Reid reported that the hemagglutinin closely resembles ...

Current nomenclature for influenza viruses (WHO 1980 ... for viruses isolated during the 1900s); The subtype [16 possible hemagglutinin and 9 possible neuraminidase subtypes].
