5 Simple Techniques For Superantigenic character of an insert unique to SARS-CoV-2

Endogenous SAgs [modify] Small lymphocyte stimulating (Mls) exotoxins were originally discovered in the thymic stromal cells of mice. These toxins are encoded by Droop genes that were included into the mouse genome from the mouse mammary tumour infection (MMTV). The existence of these genes in the mouse genome allows the mouse to express the antigen in the thymus as a way of adversely picking for lymphocytes with a variable Beta region that is vulnerable to stimulation by the viral Droop.

Similar endogenous SAg-dependent choice has yet to be recognized in the human genome, but endogenous SAgs have actually been found and are thought of playing an essential role in viral infection. Infection by the Epstein, Barr infection, for instance, is known to cause production of a Droop in contaminated cells, yet no gene for the toxin has actually been found on the genome of the infection.
