The streptococcal pyrogenic exotoxins, or erythrogenic toxins, are well known for their pyrogenicity, enhancement of endotoxic shock, and superantigenic effects on the immune system Superantigens are molecules which are mitogenic for certain T-cell subsets but do not require processing by antigen-presenting cells. They activate a much larger number of T cells than conventional antigens The superantigen is capable of binding to the beta chain (Vβ) of a characteristic set of T-cell receptors and also to the MHC class II molecule expressed on B cells, monocytes, and dendritic cells. Binding to the T-cell receptor and/or to MHC class II molecules causes the T cells to proliferate and release excessive amounts of inflammatory cytokines
