title: Suppressor cells in Trypanosoma congolense-infected mice.
abstract: Spleen cells from mice infected with T. congolense strongly suppressed lymphocyte stimulation induced in normal spleen cells by incubation with mitogens or allogeneic cells. Cell dilution studies showed that suppressor activity was extremely strong. Suppressor cell activity was markedly reduced by treatment of spleen cell populations with mitomycin-C and was unaffected by treatment with anti-Thy.1 sera and complement. Removal of cells which bound carbonyl iron or which bound to nylon columns, decreased but did not abolish suppressor activity.
