摘要: 摘要: 白细胞介素 7 受体 (IL7R) 属于Ⅰ型细胞因子受体家族成员的跨膜受体, 由特异性α链和γ链组成, 在淋巴前体细胞、 祖 B 细胞、 T 细胞、 胸腺细胞、 树突状细胞、 髓样细胞及单核细胞中均可表达。生理情况下, IL7R 是淋巴细胞发育中的关键调控分子。IL7R 在多发性硬化 (MS) 的发生中发挥了重要的作用, 其多态性与 MS 密切相关; IL7Rα 中和抗体可显著改善实验性变态反应脑脊髓炎小鼠模型的表型。上述研究提示 IL7R 可能是 MS 新的治疗靶点。

Abstract: △Corresponding Author E-mail: liyuhao@nankai.edu.cn Abstract: Interleukin 7 receptor (IL7R) is a transmembrane receptor that belongs to the type Ⅰ cytokine receptor fami⁃ ly. It consists of the cytokine-specific α-chain (IL7Rα, CD127) and the shared common cytokine γ-chain (γc, CD132). IL-7R is expressed in various cell types, including lymphoid precursor cells, pro-B cells, T cells, thymocytes, dendritic cells, myeloid cells and monocytes. Under physiological conditions, IL7R is a vital cytokine for development and survival of T and B cells. IL7R plays a key role in the pathogenesis of multiple sclerosis (MS). Single nucleotide polymorphisms (SNPs) in the gene encoding IL7Rα have emerged through genetic studies of MS patients. In experimental autoimmune encephalomy⁃ elitis (EAE) mouse model of MS, treatment with neutralizing anti-IL7Rα antibody results in significant improvement of EAE. Therefore, IL7R may serve as a novel target for MS therapies.
