The 6-Second Trick For Staphylococcus aureus - Online Textbook of Bacteriology

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

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