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 ...

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 ...

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 ...

or antigenic shift (which for flu is usually the acquisition of a whole new segment of RNA). Any scientist or physician interested in the influenza virus itself, and all its fascinating ...

Influenza is one of the most unpredictable ... Every now and then, the virus changes dramatically in a process called antigenic shift. When this occurs, people become even less immune, and the ...

To comprehend how this is possible, it is necessary to understand how influenza viruses are passed ... to form a new strain that is called antigenic shift. Such a significant mutation occurs ...

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 ...

Bragg was discussing the concept of antigenic shift in antigenic drift in influenza and how this can impact the situation. He said the more people who pick up the virus, the bigger the chance that ...
