Abstract

Natural cytotoxicity (NK) by fresh E-rosette-negative (ER-) cells from normal donors was increased after overnight incubation with purified IFN alpha and with supernatants containing IFN gamma. ER- cells from 61% of 23 patients with systemic lupus erythematosus did not show increased cytotoxicity after treatment with IFN alpha. Similarly, ER- cells from nine of 18 patients that were treated with IFN gamma-containing supernatants failed to show increased cytotoxicity. The patients who did not show enhanced cytotoxic responses to IFN had higher mean indices of disease activity than responding patients.

摘要

来自正常供体的新鲜E花环阴性(ER-)细胞的自然细胞毒性(NK)在与纯化的干扰素α以及含有干扰素γ的上清液过夜孵育后增强。23例系统性红斑狼疮患者中61%的ER-细胞在用干扰素α处理后未表现出细胞毒性增强。同样,在用含干扰素γ的上清液处理的18例患者中,有9例的ER-细胞未表现出细胞毒性增强。对干扰素未表现出增强的细胞毒性反应的患者,其疾病活动平均指数高于有反应的患者。
