title: Immunological problems in leprosy research. 1.
abstract: This Memorandum reviews the present status of knowledge of the immunology of leprosy, with particular attention to developments since the publication of a similar review in 1970. The different types of lepromin reaction and their significance in healthy contacts and in patients with tuberculoid and lepromatous leprosy are discussed. The immunological responsiveness of patients with leprosy is also considered, with special attention to in vitro methods for evaluating this response. Part 2 of the Memorandum will cover possible mechanisms of altered immune response in leprosy (including a tentative scheme to explain the possible genesis of the lepromatous lesion); genetic, nutritional, and hormonal factors; the possibility of vaccination; attempts at immunotherapy; and areas in which further research is needed. A detailed protocol for evaluating the effect of transfer factor in leprosy will be included as an annex.
