摘要 多发性硬化( multiple sclerosis ,MS)是中枢神经系统炎性脱髓鞘性自身免疫性疾病,其病因尚未明确。实验性自身免疫性脑脊髓炎模型( expreinmen-tal autoimmune encephalomyelitis , EAE )是MS 公认的动物模型,与MS在临床表现和病理特点等方面有诸多相似之处。 CD4+效应T细胞和相关细胞因子介入自身免疫应答,离子通道、黏附因子、细胞凋亡等诸多因素参与了MS/EAE 病理生理过程。尤其是以IL-23/Th17为主的炎性反应轴进一步揭示了自身免疫性疾病的发病机制。然而IL-23如何诱导Th17产生相应信号转导的机制还尚未明确。最近的研究表明,血清和糖皮质激素调节蛋白激酶1( serum and glucocorticoid-regulated protein kinase1, SGK1)可以作为IL-23的下游节点,促进Th17细胞的分化,上调细胞因子分泌水平,加重MS/EAE 的症状[1-3]。此外,SGK1作为多种细胞信号转导通路以及细胞磷酸化级联反应的功能型交汇点,在调节离子通道、细胞增殖以及细胞存活和凋亡信号转导中起到重要作用。 SGK1诸多的调节功能在 ME/EAE的病理生理过程中发挥了重要作用。
