RESUMO
The superantigenic streptococcal erythrogenic toxins A and C (ETA/SPEA and ETC/SPEC) elicit the production by human peripheral blood mononuclear cells of substantial amounts of Th1-derived cytokines (interleukin-2 [IL-2] and gamma interferon) as well as anti-inflammatory cytokines (IL-10 and IL-1 receptor antagonist). In contrast, very low levels of IL-4 and no alpha interferon were induced. The production of these cytokines after stimulation with Streptococcus pyogenes heat-killed bacteria and lipopolysaccharide from gram negative bacteria differed qualitatively and quantitatively from that elicited by the superantigens.
