TNFRSF25(肿瘤坏死因子受体超家族成员25,TNF receptor superfamily member 25)属于TNF受体超家族(TNFRSF),该家族是一类细胞表面受体,主要参与免疫调节、细胞存活和凋亡等过程。TNFRSF25也被称为死亡受体3(DR3,death receptor 3),其配体是TL1A(TNF样配体1A,TNF-like ligand 1A)。TNFRSF25主要在活化的T细胞、自然杀伤(NK)细胞和某些先天免疫细胞中表达,其功能涉及调节T细胞增殖、细胞因子分泌和炎症反应。TNFRSF25通过激活NF-κB和MAPK信号通路来调控免疫细胞的活化和凋亡。基因突变或异常表达可能导致自身免疫疾病(如类风湿性关节炎、炎症性肠病)或癌症。TNFRSF25过表达可能增强炎症反应,导致组织损伤或自身免疫疾病;而降低表达可能削弱免疫应答,增加感染风险或肿瘤发生。TNF受体超家族的共性包括含有富含半胱氨酸的胞外结构域(CRD,cysteine-rich domain)和胞内死亡结构域(DD,death domain),能够通过配体结合触发下游信号通路。TNFRSF25与TL1A的结合可促进促炎细胞因子(如IFN-γ、IL-17)的释放,影响Th1和Th17细胞的活性。在疾病中,TNFRSF25/TL1A轴被认为是治疗自身免疫疾病的潜在靶点,抑制该通路可能减轻炎症反应。
The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is expressed preferentially in the tissues enriched in lymphocytes, and it may play a role in regulating lymphocyte homeostasis. This receptor has been shown to stimulate NF-kappa B activity and regulate cell apoptosis. The signal transduction of this receptor is mediated by various death domain containing adaptor proteins. Knockout studies in mice suggested the role of this gene in the removal of self-reactive T cells in the thymus. Multiple alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported, most of which are potentially secreted molecules. The alternative splicing of this gene in B and T cells encounters a programmed change upon T-cell activation, which predominantly produces full-length, membrane bound isoforms, and is thought to be involved in controlling lymphocyte proliferation induced by T-cell activation.

由该基因编码的蛋白质是TNF受体超家族的成员。这种受体是表达优先在淋巴细胞富集的组织,并且它可以在调节淋巴细胞动态平衡的作用。该受体已显示刺激的NF-κB的活性,调节细胞凋亡。这种受体的信号转导是由各种含死亡域接头蛋白介导的。在小鼠中敲除研究显示该基因在胸腺切除自反应性T细胞的作用。这个基因编码不同同种型的多个可变剪接转录物变体已有报道,其中大部分是潜在的分泌的分子。该基因在B和T细胞的选择性剪接遇到在T细胞活化编程??的变化,这主要产生全长膜结合同种型,并且被认为是涉及控制由T细胞活化诱导的淋巴细胞增殖。 [由RefSeq的,2008年7月提供]
