山姜素对溃疡性结肠炎肠上皮屏障作用的影响
发布时间:2021-09-19 12:03
目的:炎症性肠病(inflammatory bowel diseases,IBD)是一组肠道慢性非特异性炎症性疾病,包括溃疡性结肠炎(ulcerative colitis,UC)和克罗恩病(Crohn’s disease,CD),以肠道炎症和黏膜损伤为特点。近年来,IBD的发病率显著增加,尤其是UC患者。研究表明,免疫紊乱和氧化应激反应是IBD发病的主要机制,近年研究发现,肠上皮屏障功能障碍在IBD发病中亦发挥重要作用。紧密连接(tight juction,TJ)是肠上皮屏障最重要的组成部分,其表达异常能引起肠上皮屏障通透性增加,导致肠腔内致病性抗原,如细菌、病毒、内毒素等物质进入黏膜固有层和血液循环,引发炎症和免疫反应。IBD的治疗目标是诱导并维持临床缓解及肠道黏膜愈合。研究显示,IBD患者肠黏膜TJ蛋白表达异常可发生于IBD早期阶段和复发之前,并促进疾病进展,故TJ的完整性可能对黏膜愈合发挥重要作用。TJ是由多种蛋白组成的复合体,包括跨膜蛋白、外周膜蛋白以及细胞股骨架蛋白等。其中,claudins和occludin蛋白是跨膜蛋白的主要成员,负责调控紧密连接的通透性和维持细胞极性,Z...
