摘要: 摘要: 目前, 多发性硬化症 (MS) 的病因及其发病机制尚未清楚。RIG-Ⅰ样受体(RLRs)是新发现的一类模式识别受体(PRRs), 位于细胞质内, 可识别病毒双链 RNA 的解旋酶, 并通过自身的半胱天冬酶活化募集结构域 (CARD) 与干扰素β启动刺激因子 (IPS) -1 发生相互作用, 形成 IPS-1 信号小体, 诱导干扰素Ⅰ型 (Ⅰ-IFN) 的表达, 从而启动免疫应答以及诱导抗病毒反应。研究发现, 缺乏 IPS-1 的小鼠疾病将继续恶化, 伴随高炎症反应, 从而加重轴突损伤和脱髓鞘病变。此外, 若启动免疫细胞上的 RLRs, 能缓解 MS 小鼠的炎症并预防髓鞘的断裂, 从而降低麻痹的发生率。本文就RLRs 治疗MS 的研究进展进行综述。

Abstract: Abstract: At present, the etiology and pathogenesis of multiple sclerosis are unclear. RIG-Ⅰ-like receptors are a new⁃ ly discovered pattern recognition receptors (RLRs), which are located in cytoplasm. They can recognize the helicase of viral dsRNAs, and interact with interferon beta promoter stimulator (IPS)-1 through their caspase activation recruitment domain (CARD), then form IPS-1 signalsome and induce the expression of interferon type Ⅰ (Ⅰ-IFN), thereby initiate innate im⁃ mune response and induce antiviral response. Recent studies have found that mice lacking IPS-1 would develop exacerbated disease and accompanied by markedly higher inflammation, increasing axonal damage and demyelination. Furthermore, initi⁃ ating the RIG-Ⅰ-like helicase receptor on the immune cells can alleviate inflammation and myelin fracture in multiple scle⁃ rosis of mouse model, thus limit the incidence of paralysis. This paper is a review about the research progress on RLRs in the treatment of multiple sclerosis.
