男性同性恋者不明原因的全身性淋巴结病可能是获得性免疫缺陷综合征的前驱症状,与细胞介导的免疫功能受损、T辅助诱导细胞与T抑制细胞毒性细胞(由T4和T8单克隆抗体定义)的比率低和高丙种球蛋白血症有关。我们使用一组单克隆抗体(Ia、T17、TQ 1和Leu-8)对T细胞进行了双标记研究,据报道,这些抗体可检测T4和T8 T细胞群的激活或功能亚群。T4:TQ 1-或T4:Leu-8-亚群是B细胞应答的主要辅助亚群,通常出现在淋巴结病患者中。相反亚群T4:TQ 1+或T4:Leu-8+的抑制导致T4 T细胞缺陷。类似地,TQ 1和Leu-8标志物描述了T8 T细胞的异常:T8:TQ 1-或T8:Leu-8-亚群升高,而T8:TQ 1+或T8:Leu-8+亚群正常表示。我们没有发现使用T17或Ia单克隆抗体过度激活T4 T细胞的证据。我们确实发现了Ia阳性T细胞的总体增加;然而,这是由于T8:Ia+细胞的增加。在功能研究中,美洲商陆诱导的免疫球蛋白产生低于正常水平。大多数淋巴结病患者在与正常B细胞结合时具有正常的T辅助细胞功能。美洲商陆反应减弱可以部分解释为T4:TQ 1+(或T4:Leu-8+)子集(具有较小的帮助相关功能)的抑制和/或大于预期的抑制。然而,低于正常的美洲商陆反应不能完全解释免疫调节T细胞异常,因为我们也发现了淋巴结病患者的B细胞反应的内在缺陷。
Unexplained, generalized lymphadenopathy in homosexual men, which can be a prodrome to the acquired immunodeficiency syndrome, is associated with impaired cell-mediated immunity, a low ratio of T helper-inducer to T suppressor-cytotoxic cells (defined by the T4 and T8 monoclonal antibodies), and hypergammaglobulinemia. We performed double-marker studies on T cells by using a panel of monoclonal antibodies (Ia, T17, TQ1, and Leu-8), which reportedly detect activation or functional subsets of the T4 and T8 T cell populations. The T4:TQ1- or T4:Leu-8- subset, which is the major helper subset for B cell responses, is normally represented in lymphadenopathy patients. A depression in the reciprocal subset, T4:TQ1+ or T4:Leu-8+, accounts for the T4 T cell defect. Similarly, the TQ1 and Leu-8 markers delineate the abnormality of T8 T cells: the T8:TQ1- or T8:Leu-8- subset is elevated, whereas the T8:TQ1+ or T8:Leu-8+ subset is normally represented. We found no evidence of excessive activation of T4 T cells by using the T17 or Ia monoclonal antibodies. We did find an overall increase in Ia-positive T cells; however, this was due to increased T8:Ia+ cells. In functional studies, immunoglobulin production induced by pokeweed was subnormal. Most lymphadenopathy patients had normal T helper cell function when combined with normal B cells. The dampened pokeweed responses could be partially explained by depression of the T4:TQ1+ (or T4:Leu-8+) subset (which has minor help-associated function) and/or greater than expected suppression. However, subnormal pokeweed responses could not be totally explained by immunoregulatory T cell abnormalities because we also found an intrinsic defect in the B cell responses of lymphadenopathy patients.
