RESUMO
The in vitro response to sheep erythrocytes of mesenteric lymph node cells from mice infected with the larval cestode Taenia crassiceps is significantly depressed and can be restored to control levels by addition of activated peritoneal cells depleted of functional T or B lymphocytes. Adherent mesenteric lymph node cells from infected mice are unable to reconstitute the in vitro response to sheep erythrocytes of normal nonadherent cells. The responses of mesenteric lymph node cells from infected mice to the T-lymphocyte mitogens concanavalin A and phytohemagglutinin and the B-lymphocyte mitogen lipopolysaccharide are normal. Mesenteric lymph node cells from infected mice do not suppress the in vitro response to sheep erythrocytes of normal mesenteric lymph node cells. These results suggest that the immunodepression in T. crassiceps-infected mice is primarily the result of alterations in functional accessory cells.
