Spleen and lymph node cells of Trypanosoma cruzi-infected mice were studied for mitogen-induced responsiveness in terms of proliferation and lymphokine production (IL-2, IFN-gamma). Splenocyte (SP) as well as lymph node cell (LN) proliferation and IL-2 production were depressed during the acute phase of the infection. Proliferative capacity of LN cells recovered completely and that of SP partially during the chronic phase. In contrast to these suppressive effects, the mitogen-induced IFN-gamma response was enhanced. In vitro co-incubation of normal SP or LN cells with trypomastigotes resulted in a reduced mitogen-induced cell proliferation and IL-2 secretion, similar to those seen with cells taken from infected mice. In contrast, trypomastigotes exerted a stimulatory activity on the mitogen-induced IFN-gamma response of both SP and LN cells. Addition of lymph node cells from T. cruzi-infected mice (LN-I) to lymph node cells of control mice (LN-C) suppressed strongly the mitogen-induced responsiveness of such cocultures. A marginal level of suppression was recorded in cocultures of spleen cells from infected mice (SP-I) and control spleen cells (SP-C). The potent suppressive cells within LN-I populations were identified as macrophage-like and such cells were absent in SP-C and peritoneal exudate cells from T. cruzi infected animals.
