Effect of treatment with anti-interleukin-2 (IL-2) monoclonal antibody (mAb) S4B6.31 on concanavalin A (Con A)-stimulated spleen cell proliferation from normal mice in cultures treated with interleukin-12 (IL-12) (a), and the effect of the same treatments on parasite antigen (T-Ag)-stimulated proliferation in NG-monomethyl-l-arginine (NMMA)-treated cultures of spleen cells obtained from day-12 Trypanosoma cruzi-infected mice (b). Values are expressed as arithmetic means of triplicate cultures ±standard deviation. The results are representative of three experiments.
