Abstract

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.

摘要

瘤型麻风患者的外周血淋巴细胞通常在体外对麻风杆菌抗原的刺激无反应。相比之下,我们发现无反应患者的T细胞与有反应患者或健康接触者的巨噬细胞联合时,对麻风杆菌有良好反应。相反,有反应患者或健康接触者的T细胞与无反应患者的巨噬细胞联合时则无反应。因此,似乎在使用瘤型麻风患者细胞进行的体外试验中通常观察到的无反应是由于其巨噬细胞未能以免疫原性形式呈递麻风杆菌抗原。
