Abstract

Peripheral blood mononuclear cells, PBMC, from 64 HIV-1-infected patients were tested for natural killer (NK) and antibody-dependent cellular cytotoxicity (ADCC) functions against HIV-1-infected U937 clone 2 cells. The ADCC function was tested both with serum and effector cells from the same patient, with an HIV-1 antibody positive serum and with rabbit IgG antibodies against beta 2-microglobulin expressed on the virus-infected target cells. NK and ADCC functions were often found to be suppressed in HIV-1-infected individuals regardless of the severity of HIV-1 infection. The fact that impaired effector cell functions could be detected even in asymptomatic carriers, suggests that profound changes in cellular immunity may be present at an early stage of HIV-1 infection.

摘要

对64例HIV-1感染患者的外周血单个核细胞(PBMC)进行检测,以评估其针对HIV-1感染的U937克隆2细胞的自然杀伤(NK)功能和抗体依赖性细胞毒性(ADCC)功能。使用来自同一患者的血清和效应细胞、HIV-1抗体阳性血清以及针对病毒感染靶细胞上表达的β2-微球蛋白的兔IgG抗体来检测ADCC功能。无论HIV-1感染的严重程度如何,HIV-1感染个体的NK和ADCC功能常常被发现受到抑制。即使在无症状携带者中也能检测到效应细胞功能受损,这一事实表明在HIV-1感染的早期阶段可能就存在细胞免疫的深刻变化。
