N2 - The major surface protease of Leishmania major, gp63, has been suggested as a vaccine candidate for cutaneous leishmaniasis. In this study gp63 was purified from L. major promastigotes. A panel of human T-cell clones recognizing this protein were generated from individuals who had previously had self-healing cutaneous leishmaniasis. The T-cell clones expressed CD4, and the alpha chain of the T-cell antigen receptor. GP63 reactive T-cell clones activated by antigen or by immobilized anti-CD3 antibody released relative large amounts of interferon-gamma and no or little interleukin-4, thereby resembling Th1 cells. Autologous mononuclear cells and Epstein-Barr virus-transformed B cell lines were equally efficient in presenting the antigen to the T cells. The gp63 reactive T cells induced resistance to infection in cultured human macrophages by L. major. The data confirm that human CD4+ T cells recognizing gp63 can take part in the host defence against L. major infections.
