为了检验白细胞介素2(IL-2)分泌不足可能是获得性免疫缺陷综合征(AIDS)患者T细胞和AIDS相关复合物(ARC)产生巨噬细胞活化淋巴因子γ干扰素(IFN-γ)的能力受损的基础这一假设,我们使用了五种特异性微生物抗原来检测IL-2的产生。32例艾滋病患者中只有1例(3%)的单核细胞分泌正常水平的IL-2,21例(66%)未能产生任何可检测的IL-2。在36例ARC患者中,9例(25%)IL-2生成正常,11例(31%)缺失。鉴于这些结果,测试重组(r)IL-2刺激或增强IFN-γ产生的能力。rIL-2(10 U/ml)单独刺激来自对照、ARC和AIDS患者的细胞分别分泌93 +/- 25、99 +/- 33和7 +/- 3 U/ml的IFN-γ。rIL 2(10 U/ml)加抗原对对照组的平均IFN-γ水平没有诱导变化,对17名AIDS患者增加了4.4倍(16 +/-16 vs. 71 +/-21 U/ml),对19名单独抗原产生异常IFN-γ的ARC患者增加了7.2倍(18 +/-5 vs. 130 +/-27 U/ml)。个体应答表明,17例机会性感染AIDS患者中的6例(35%)和19例ARC患者中的12例(63%)对10-100 U/ml rIL-2有明显应答。这些结果(a)证明了AIDS和ARC T细胞对抗原诱导的IL-2分泌的严重损害,(B)表明,在体外,某些患者的单核细胞可以对rIL-2产生应答,产生增强的IFN-γ,因此(c)表明,在选定的患者中,rIL-2可能对机会性感染具有潜在的有益治疗(AIDS)或预防(ARC)作用。
To test the hypothesis that deficient interleukin 2 (IL-2) secretion may underlie the impaired capacity of T cells from patients with Acquired Immunodeficiency Syndrome (AIDS) and the AIDS-related complex (ARC) to generate the macrophage-activating lymphokine, gamma interferon (IFN-gamma), we used five specific microbial antigens to examine IL-2 production. Mononuclear cells from only one of 32 (3%) AIDS patients secreted normal levels of IL-2, and 21 (66%) failed to produce any detectable IL-2. For 36 ARC patients, IL-2 generation was normal in nine (25%) and absent in 11 (31%). Given these results, recombinant (r) IL-2 was tested for its capacity to stimulate or enhance IFN-gamma production. rIL-2 (10 U/ml) alone stimulated cells from controls, ARC, and AIDS patients to secrete 93 +/- 25, 99 +/- 33, and 7 +/- 3 U/ml of IFN-gamma, respectively. rIL 2 (10 U/ml) plus antigen induced no change in mean IFN-gamma levels for controls, a 4.4-fold increase for 17 AIDS patients (16 +/- 16 vs. 71 +/- 21 U/ml), and a 7.2-fold increase (18 +/- 5 vs. 130 +/- 27 U/ml) for 19 ARC patients with abnormal IFN-gamma generation to antigen alone. Individual responses indicated that six of the 17 (35%) AIDS patients with opportunistic infections and 12 of the 19 (63%) with ARC were apparent responders to 10-100 U/ml of rIL-2. These results (a) document profound impairment in antigen-induced IL-2 secretion by AIDS and ARC T cells, (b) indicate that, in vitro, mononuclear cells from certain patients can respond to rIL-2 with enhanced IFN-gamma production, and thus (c) suggest that in selected patients rIL-2 might have a potentially beneficial therapeutic (AIDS) or prophylactic (ARC) effect against opportunistic infections.
