IL26(白细胞介素-26,Interleukin-26)是一种由T细胞(特别是Th17细胞)和自然杀伤细胞(NK细胞)分泌的细胞因子,属于IL-10细胞因子家族(IL-10 family)。该家族成员通常具有免疫调节功能,包括抗炎或促炎作用,且结构上具有相似的螺旋束折叠模式。IL26的主要生物学功能是促进炎症反应,通过激活STAT3(信号转导和转录激活因子3)信号通路刺激上皮细胞和免疫细胞产生促炎细胞因子(如IL-1β、IL-6和TNF-α)。其作用位点集中在黏膜表面(如肠道、呼吸道和皮肤),通过与IL-20R1和IL-10R2组成的异源二聚体受体结合发挥作用。IL26的突变可能导致免疫功能异常,例如过度炎症或免疫抑制,但目前研究较少。该基因与多种疾病相关,包括自身免疫性疾病(如银屑病、类风湿性关节炎)、慢性炎症性肠病(如克罗恩病)和呼吸道感染(如结核病)。当IL26过表达时,可能加剧组织炎症和自身免疫反应,而降低表达可能削弱黏膜免疫防御,增加感染风险。IL26还能影响其他基因的表达,例如上调抗菌肽(如β-防御素)以增强宿主防御。IL-10家族的其他成员包括IL-10、IL-19、IL-20、IL-22、IL-24和IL-29,它们均通过JAK-STAT通路调控免疫反应,但功能各异,有的抗炎(如IL-10),有的促炎(如IL-26)。专业术语解释:细胞因子(cytokine)是细胞间传递信号的蛋白质;STAT3是一种参与基因转录调控的蛋白质;Th17细胞是辅助性T细胞的一个亚群,主要分泌IL-17等促炎因子;异源二聚体(heterodimer)指由两种不同蛋白质组成的复合体。

该基因特别是在疱疹病毒samimiri转化的T细胞识别它的表达。所编码的蛋白质是IL10细胞因子家族的一个成员。它是一种分泌蛋白,并且可以作为同二聚体起作用。该蛋白被认为通过疱疹samimiri感染后促进T细胞的转化表型。 [由RefSeq的,2008年7月提供]
