溃疡性结肠炎(UC)是一种发病率高、发病年龄小的慢性复发性肠道炎症性疾病。近年来,在UC的发病机制方面有了一些有趣的发现。由富含O-糖基化的粘蛋白复合物组成的粘液屏障不仅为肠道微生物提供营养和栖息地,而且还协调细菌的驯服。反过来,肠道微生物群调节粘蛋白的产生和分泌以及粘液层的分层。微生物群与其“黏糊糊”的伙伴粘液屏障之间的积极双向交流似乎是一个持续进行的协奏曲,维持肠道生态微环境的稳态。任何异常都可能引起肠道群落的紊乱,从而引起炎症损伤。我们的综述主要集中在粘液屏障和肠道微生物组之间的复杂通信,以探索UC治疗的一种有前途的新途径。
Ulcerative colitis (UC) is a chronic recurrent intestinal inflammatory disease characterized by high incidence and young onset age. Recently, there have been some interesting findings in the pathogenesis of UC. The mucus barrier, which is composed of a mucin complex rich in O-glycosylation, not only provides nutrients and habitat for intestinal microbes but also orchestrates the taming of germs. In turn, the gut microbiota modulates the production and secretion of mucins and stratification of the mucus layers. Active bidirectional communication between the microbiota and its ‘slimy’ partner, the mucus barrier, seems to be a continually performed concerto, maintaining homeostasis of the gut ecological microenvironment. Any abnormalities may induce a disorder in the gut community, thereby causing inflammatory damage. Our review mainly focuses on the complicated communication between the mucus barrier and gut microbiome to explore a promising new avenue for UC therapy.
