辅助性T细胞(Th)-2是过敏性哮喘的主要参与者;然而,控制Th 2介导的炎症的机制知之甚少。在这里,我们发现,增强表达的Grail,E3泛素连接酶,在Th 2细胞依赖于IL-4信号传导组件,Stat 6和Gata 3的结合和反式激活的Grail启动子。Grail缺陷的T细胞导致Th 2效应细胞因子在体外和体内的表达增加,Grail缺陷小鼠更容易患过敏性哮喘。从机制上讲,Grail缺陷型Th 2细胞的效应功能增强是由Stat 6和IL-4受体α链表达增加介导的。Grail与Stat 6相互作用并靶向其进行泛素化和降解。因此,我们的研究结果表明,Grail通过负反馈回路在控制Th 2发育中起着关键作用。
T helper (Th)-2 cells are the major players in allergic asthma; however, the mechanisms that control Th2-mediated inflammation are poorly understood. Here we find that enhanced expression of Grail, an E3 ubiquitin ligase, in Th2 cells depends on IL-4-signaling components, Stat6 and Gata3 that bind to and transactivate the Grail promoter. Grail-deficiency in T cells leads to increased expression of Th2 effector cytokines in vitro and in vivo and Grail deficient mice are more susceptible to allergic asthma. Mechanistically, the enhanced effector function of Grail-deficient Th2 cells is mediated by increased expression of Stat6 and IL-4 receptor α-chain. Grail interacts with Stat6 and targets it for ubiquitination and degradation. Thus, our results indicate that Grail plays a critical role in controlling Th2 development through a negative feedback loop.
