艾滋病(AIDS)的主要特点是CD_4~+T细胞缺乏,自然杀伤(NK)细胞数目减少。近期有人提出其发生机理可能与HIV诱发的自身抗体有关,因而对HIV感染者体内的抗NK细胞抗体进行了检测。 应用荧光激活细胞分类仪(FACS)分别测定了67例HIV感染者和37例健康人血液中的抗NK细胞抗体(CD56~+CD3)。结果发现HIV感染者中13例为阳性,占19.4％,而正常人均为阴性。同时还检测了血清抗T AIDS is characterized by a lack of CD_4 ~ + T cells and a reduction in the number of natural killer (NK) cells. Recently, it was suggested that its mechanism may be related to HIV-induced autoantibodies, and thus anti-NK cell antibodies in HIV-infected individuals were detected. The anti-NK cell antibodies (CD56 ~ + CD3) in 67 HIV-infected and 37 healthy controls were measured by fluorescence activated cell sorter (FACS). The results found that 13 HIV-infected patients were positive, accounting for 19.4%, while the normal were negative. Also tested for serum anti-T
