Six families with HLA-D-identical siblings suffering from leprosy were studied. Lymphocytes and macrophages isolated from the peripheral blood were co-cultured with allogeneic, HLA-D-identical cells and stimulated with M. leprae antigens and concanavalin A. Tuberculoid patients had circulating lymphocytes which showed marked functional suppression of lymphoproliferative responses to antigen and mitogen. In contrast, lepromatous patients showed weak lymphocyte suppressor activity. Macrophages derived from responder individuals augmented, while those derived from lepromatous patients inhibited, M. leprae-induced proliferation of lymphocytes.
对六个有患麻风病的 HLA - D 相同同胞的家庭进行了研究。从外周血中分离出的淋巴细胞和巨噬细胞与 HLA - D 相同的异基因细胞共培养,并用麻风杆菌抗原和刀豆球蛋白 A 刺激。结核样型患者的循环淋巴细胞对抗原和丝裂原的淋巴细胞增殖反应表现出明显的功能抑制。相比之下,瘤型患者的淋巴细胞抑制活性较弱。来自反应者个体的巨噬细胞增强了麻风杆菌诱导的淋巴细胞增殖,而来自瘤型患者的巨噬细胞则抑制了这种增殖。
