摘要 白介素13(interleukin-13,IL-13)是主要由活化的Th2细胞分泌的免疫调节因子,在过敏性炎症反应过程中起着重要的作用。其各种功能通过复杂的受体系统来完成,包括IL-4受体α(IL-4Ra,CD124)和其他同族的两个细胞表面蛋白:IL-13受体α1(IL-13Rα1,CD231α1)和IL-13受体α2(IL-13Rα2,CD231α2)。在IL-13R中IL-13Rα1和IL-4Rα以同源二聚体形式存在。相反IL-13Rα2由于它的较短的胞内蛋白形式被认为是一个诱导受体。IL-13Rα2以胞膜蛋白、胞内蛋白和胞外可溶性蛋白3种形式存在。近来报道显示,膜性IL-13Rα2可能有信号转导的功能,可溶性IL-13Rα2可调节IL-13反应。可溶性受体IL-13Rα2比诱导受体有着更加复杂的功能。在这里我们将详述IL-13R的亚型并讨论IL-13Rα2功能。 Interleukin(IL) 13 is an immunoregulatory cytokine secreted predominantly by activated T-helper type 2 (Th2) cells,and it has been identified as cruciα1 factor in developing α1lergic inflammatory respnses. Its diverse functions are mediated by a complex receptor system including IL-4 receptor a(IL-4Rα; CD124) and two other cognate cell surface proteins, IL-13Rα1 (CD231α1) and IL-13Rα2 (CD231α2). IL-13Rα1 forms a heterodimer with IL-4Ra that is a signα1ing IL-13R. In contrast, IL-13Rα2 has been thought to be a decoy receptor due to its short cytoplasmic tail. IL-13Rα2 exists on the cell membrane, intracellularly, and in soluble form. Recent reports reveα1ed that membrane IL-13Rα2 may have some signα1ing capabilities, and soluble IL-13Rα2 is a criticα1 endogenous modulator for IL-13 responses. The receptor has more complicated functions than a simple decoy receptor. This review describes the isoforms of IL-13Rα2 and discusses newly reveα1ed functions of IL-13Rα2.
