Levels of the cytokines IFN-gamma, IL-10, TGF-beta 1 and TNF-alpha were measured in supernantant of peripheral blood mononuclear cells (PBMC) cultures, stimulated with specific M. leprae antigen (sonicated and whole). The cytokines iNOS, IL-10 and TGF-beta 1 were detected by immunohistochemistry in skin biopsies.Results: BT patients produced higher levels of IFN-gamma than BL patients; iNOS expression in skin lesions was also higher in BT patients. TGF-beta 1 was detected in more cells in BL patients; IL-10 expression was similar in both groups. There was a negative correlation between iNOS and TGF-beta 1 expression in skin biopsies, positive correlation between TGF-beta 1 in skin lesions and bacillary index, as well as positive correlation between iNOS detected in skin biopsies and PBMC IFN-gamma production.Conclusions: The BT patients had a mainly a Th1-profile of cytokines in their skin lesions and BL patients had aTh2 profile.
