Annotation
coordinate IM with specific microbe /‌immunol (IM); for interaction of superantigens with endotoxins, coordinate with ENDOTOXINS or specifics
Scope Note
Microbial antigens that have in common an extremely potent activating effect on T-cells that bear a specific variable region. Superantigens cross-link the variable region with class II MHC proteins regardless of the peptide binding in the T-cell receptor's pocket. The result is a transient expansion and subsequent death and anergy of the T-cells with the appropriate variable regions.
