Abstract
The complete set of currently known streptococcal superantigens (SAgs) was tested for efficacy to induce in vitro cytokine responses from 5 different blood donors using the Luminex 100 system. Cytokine responses varied significantly between individual SAgs and between donors with a mixed Th1/Th2 response in 3 donors and a predominantly Th1 or Th2 response in the other 2 donors. Our results suggest that streptococcal SAgs might be involved not only in acute streptococcal diseases but also in chronic inflammation and autoimmune diseases.
