In areas of Leishmania chagasi transmission the ability to control leishmania infection is associated with IFN-gamma production. In visceral leishmaniasis down-regulation of T cell responses is mediated by interleukin-10 (IL-10). In this study we evaluated the lymphoproliferative response, IFN-gamma and IL-10 production on lymphocyte cultures stimulated with recombinant leishmania antigens in s...
