Recent evidence suggests the presence of a suppressor T cell defect in systemic lupus erythematosus. We confirm the presence of such a defect and find a strong quantitative correlation between the loss of suppressor T cell function and the activity of SLE as measured by the presence of antibodies to native DNA. In addition, the serum of patients with active SLE contains a soluble factor which when incubated with normal peripheral blood lymphocytes induces a suppressor T cell defect. These data are consistent with the suppressor cell defect being involved in the propagation and possible the pathogenesis of SLE, and suggests a positive feedback mechanism whereby a suppressor cell defect results in autoantibodies including antibody to suppressor cells.
近期证据表明系统性红斑狼疮存在抑制性T细胞缺陷。我们证实了这种缺陷的存在,并发现抑制性T细胞功能丧失与通过抗天然DNA抗体的存在所衡量的SLE活动度之间存在很强的定量相关性。此外,活动性SLE患者的血清含有一种可溶性因子,当与正常外周血淋巴细胞一起孵育时,会诱导抑制性T细胞缺陷。这些数据与抑制性细胞缺陷参与SLE的传播以及可能的发病机制相一致,并提示了一种正反馈机制,即抑制性细胞缺陷导致自身抗体包括抗抑制性细胞抗体的产生。
