Hypertension:抗原提呈细胞介导高盐诱导的肾脏炎症和高血压的发生

2019-08-20 MedSci MedSci原创

现已十分明确高血压的盐敏感机制涉及肾脏、血管系统和中枢神经系统,;但近期研究表明,免疫细胞可以感知钠(Na+)。抗原提呈细胞(APCs),包括树突细胞,通过激活T细胞和产生细胞因子介导炎症。Beusecum等人发现Na+通过包含上皮拿通道的α和γ亚单位的阿米洛利(amiloride)敏感性通道进入树突细胞,介导免疫原性IsoLG(异亮氨酸)-蛋白加合物以烟酰胺腺嘌呤二核苷酸磷酸氧化酶依赖性方式形成

现已十分明确高血压的盐敏感机制涉及肾脏、血管系统和中枢神经系统,;但近期研究表明,免疫细胞可以感知钠(Na+)。抗原提呈细胞(APCs),包括树突细胞,通过激活T细胞和产生细胞因子介导炎症。

Beusecum等人发现Na+通过包含上皮拿通道的α和γ亚单位的阿米洛利(amiloride)敏感性通道进入树突细胞,介导免疫原性IsoLG(异亮氨酸)-蛋白加合物以烟酰胺腺嘌呤二核苷酸磷酸氧化酶依赖性方式形成,进而导致炎症和高血压

现研究人员发现了一种新的通路:APCs上的盐敏感性激酶SGK1(血清/糖皮质激素激酶1)介导盐诱导的ENaC-α和ENaC-γ表达并组装,并通过激活烟酰胺腺嘌呤二核苷酸磷酸氧化酶和促进IsoLG-蛋白加合物的形成促进盐敏感性高血压。

CD11c+细胞缺乏SGK1的小鼠,以高盐喂养时,肾脏炎症、内皮功能障碍均得到保护,最终发展为钝性高血压。高盐处理的CD11c+ APCs表现为ENaC-γ的表达增加(ENaC-γ与ENaC-α免疫共沉淀)。这一现象与多种烟酰胺腺嘌呤二核苷酸磷酸氧化酶亚基的激活和表达增加有关。敲除或药物抑制CD11c+细胞的SGK1可阻断高盐诱导的ENaC和烟酰胺腺嘌呤二核苷酸磷酸氧化酶表达。

本研究表明,CD11c+ APCs的SGK1参与盐敏性高血压的发病机制。
