ABSTRACT
Peripheral blood derived macrophages from lepromatous leprosy patients were unable to interact with lymphocytes in the presence of M. leprae. This lack of interaction is probably not associated with membrane HLA-Dr antigens since trypsin and colchicine restored M. leprae induced depression in the latter but were unable to bring about a positive interaction. Two possible defects exist therefore in the lepromatous macrophage. These are an innate inability to process and present M. leprae antigens to lymphocytes and an induced inability to express some membrane receptors, an event detrimental to the normal functioning of a macrophage.
