Abstract: | Mice infected with Trypanosoma cruzi develop immunosuppression with a deficient production of interleukin-2 (IL-2). In this situation the deficient concanavalin A (Con A) T-cell response is not corrected by addition of exogenous IL-2. Here we show that elimination of cycling cells by treatment of infected mice with hydroxyurea (HU) fully restored the ability of spleen cells to respond to IL-2. Further, capacity for IL-2 production was restored to HU treated infected mice, but not as completely as the response to IL-2. |
