系统性红斑狼疮(SLE)是一种病因不明的多系统复杂性自身免疫性疾病(OMIM 152700)。近年来,SLE易感性的遗传成分已经被确定。最近在SLE相关性研究中取得的成功已经确定了包括IRF 5在内的基因(参考文献)。FCGR3B。位于显示与SLE遗传连锁的间隔内的两个肿瘤坏死因子(TNF)超家族成员是TNFSF 4(也称为OX 40 L; 1 q25),其在活化的抗原呈递细胞(APC)和血管内皮细胞上表达,以及其独特的受体TNFRSF 4(也称为OX 40; 1 p36),其主要在活化的CD 4 + T细胞上表达。TNFSF 4参与后,TNFSF 4可为活化的CD 4 + T细胞产生有效的共刺激信号(参考文献)。使用基于家族和病例对照的研究设计,我们发现TNFSF 4的上游区域包含SLE的单一风险单倍型,这与细胞表面TNFSF 4和TNFSF 4转录物的表达增加相关。我们假设TNFSF 4表达增加通过定量增加T细胞-APC相互作用或通过TNFSF 4影响T细胞活化的功能结果而易患SLE。
Systemic lupus erythematosus (SLE) is a multisystem complex autoimmune disease of uncertain etiology (OMIM 152700). Over recent years a genetic component to SLE susceptibility has been established. Recent successes with association studies in SLE have identified genes including IRF5 (refs.) and FCGR3B. Two tumor necrosis factor (TNF) superfamily members located within intervals showing genetic linkage with SLE are TNFSF4 (also known as OX40L; 1q25), which is expressed on activated antigen-presenting cells (APCs) and vascular endothelial cells, and also its unique receptor, TNFRSF4 (also known as OX40; 1p36), which is primarily expressed on activated CD4+ T cells. TNFSF4 produces a potent co-stimulatory signal for activated CD4+ T cells after engagement of TNFRSF4 (ref.). Using both a family-based and a case-control study design, we show that the upstream region of TNFSF4 contains a single risk haplotype for SLE, which is correlated with increased expression of both cell-surface TNFSF4 and the TNFSF4 transcript. We hypothesize that increased expression of TNFSF4 predisposes to SLE either by quantitatively augmenting T cell–APC interaction or by influencing the functional consequences of T cell activation via TNFRSF4.
