Every now and then, the virus changes dramatically in a process called antigenic shift. When this occurs, people become even less immune, and the likelihood of disease spread dramatically increases.

The immune system responds to an infection by producing antibodies that recognize and bind to the cell surface of the pathogen, thus marking it as an intruder and triggering an immune response. For ...

"This strategy is known as antigenic variation," explains physicist Maria Colomé-Tatché, who is Professor of Functional Genomics and Cell Biology at LMU's Biomedical Center and leader of the ...

These strains occur because of the phenomenon known as antigenic shift, in which humans are infected with avian influenza viruses or viruses that contain a combination of genes from human and ...

In 1958, a new strain of influenza A with different HA and NA was identified and antigenic shift was discovered; the need for a trivalent vaccine was recognized. Technical advances have made it ...

When two or more existing strains combine to form a new strain that is called antigenic shift. Such a significant mutation occurs, for instance, when a flu virus from a bird and a flu virus from ...

Catani and colleagues provide data on antigenic properties of neuraminidase proteins of pandemic H1N1 and show that antigenic diversity of the neuraminidase from 2009 to 2020 largely falls into two ...
