Cytokines are increasingly recognized as important components of the cellular immune responses to intracellular pathogens. In this study, we analyzed the production of TGF-beta, IL-10 and IFN-gamma by PBMC of unexposed naïve subjects and LCL patients after stimulation with live Leishmania guyanensis (L.g.). We demonstrated that IFN-gamma is produced in controls and LCL patients, IL-10 only in LCL patients and TGF-beta only in naïve subjects. Furthermore, in naive subjects, neutralization of TGF-beta induced IL-10 production. IL-10 produced in naïve subjects when TGF-beta is neutralized or in LCL patients did not modify the IFN-gamma production but inhibit reactive nitrogen species production. Analysis of the phenotype of IL-10 producing cells in naive subjects when TGF-beta is neutralized clearly showed that they are memory CD45RA- CD8+ T cells. In LCL patients, IL-10 producing cells are both CD45RA- CD4 and CD8+ T cells. The role of these IL-10 producing CD8+ T cells in the development of the diseases should be carefully evaluated.
