Enhanced susceptibility to superantigen-associated streptococcal sepsis in human leukocyte antigen-DQ transgenic mice.

Bacterial superantigens are believed to cause septic shock, although, because of the lack of superantigen-sensitive infection models, proof that superantigenicity underlies shock pathogenesis is lacking. This work demonstrates a clear superantigen effect in septic shock resulting from bacterial infection. Transgenic expression of human leukocyte antigen… CONTINUE READING
