Popis: Cellular populations involved in resistance against T. cruzi infection were characterized from mice chronically infected with the parasite. Mice transfused with spleen cells (SC), nylon-wool-non-adherent spleen cells (NWNA) or sera from mice chronically infected with T. cruzi , showed an enhanced resistance against challenge with the parasite. The protective activity of NWNA but not of SC was completely abrogated by treatment with anti-Thyl.2 monoclonal antibodies (mAb) and complement (C). Pretreatment of NWNA cells from chronically infected mice with either anti-L3T4 or anti-Lyt 2.2 mAb partially reduced the transfer of resistance. When both L3T4 + and Lyt2.2 + cells were depleted from NWNA populations, transfer of resistance was abolished. These results appear to indicate that L3T4 + , Lyt2.2 + T cell subsets and non-T cells are involved in the immunity to T. cruzi .
