Abstract: Visceral leishmaniasis is characterized by severe immune suppression of the host. This suppression of the host immune system is primarily mediated by the immunosuppressive cytokine Interleukin-10 (IL-10), whose levels are significantly up-regulated during leishmaniasis. This immune suppression is reflected at the level of T-cell dysfunction and abrogation of leishmaniacidal molecules along with a dampened Th1 cytokine response. In the present study, we showed in vivo neutralization of IL-10 by administration of anti IL-10 monoclonal antibodies (mAb) could confer protection against leishmanial pathogenesis. This protective response was primarily mediated by a strong induction of T cell proliferation along with a Th1 biased cytokine response which was further aided by the generation of, leishmanicidal molecules, nitric oxide.
