Peripheral blood lymphocytes from patients suffering from lepromatous leprosy do not normally react in vitro to stimulation by Mycobacterium leprae antigens. In contrast, we found that T cells from non-responding patients in combination with macrophages from responding patients or healthy contacts did respond well to M. leprae. Conversely, T cells from responding patients or healthy contacts in combinations with macrophages from non-responding patients failed to respond. It seems, therefore, that the lack of response normally observed in in vitro tests using cells from lepromatous leprosy patients is due to a failure of their macrophages to present M. leprae antigens in an immunogenic form.
