Evaluation of T cells, B cells and Ig. in tissues of human cutaneous leishmaniasis
Cutaneous leishmaniasis (CL) is a granulomatous skin disease. The healing of the CL. lesions is attributed to the delayed immunity developed against the amastigotes of the parasite. However, in some cases in spite of the development of strong delayed hypersensitivity CL. lesions failed to heal. In this paper, it was intended to assess the role of immunity in the lesions of human cutaneous leishmaniasis. The results showed that the helper cells predominated the suppressor ones, the mean percentage of B lymphocytes was 25 and the immunoglobulins particularly the IgG were demonstrated by being positively stained. On the other hand, the complement (C3) was within the normal range.
