人类胃肠道(GI)内存在着大量的微生物,它们不断地影响着宿主的病理生理反应。尽管已有丰富的宏基因组数据,但肠道微生物群的功能动力学仍有待于在各种健康和疾病条件下进行探索。微生物群从饮食产品中产生各种代谢产物,影响宿主的健康和病理生理功能。由于肠道微生物代谢产物在非常接近肠道上皮的地方产生,因此推测它们对肠道屏障功能和免疫应答具有显著影响。本文就近年来肠道微生物代谢产物在肠屏障功能调节中的研究进展作一综述。虽然这些代谢物的作用机制才刚刚开始出现,但它们主要指向一小组控制肠道屏障功能的共享途径。随着技术的发展和知识的拓宽,利用有益的微生物群及其代谢产物来恢复病理生理平衡可能会被证明是一种非常有用的补救工具。
The human gastrointestinal tract (GI) harbors a diverse population of microbial life that continually shapes host pathophysiological responses. Despite readily available abundant metagenomic data, the functional dynamics of gut microbiota remain to be explored in various health and disease conditions. Microbiota generate a variety of metabolites from dietary products that influence host health and pathophysiological functions. Since gut microbial metabolites are produced in close proximity to gut epithelium, presumably they have significant impact on gut barrier function and immune responses. The goal of this review is to discuss recent advances on gut microbial metabolites in the regulation of intestinal barrier function. While the mechanisms of action of these metabolites are only beginning to emerge, they mainly point to a small group of shared pathways that control gut barrier functions. Amidst expanding technology and broadening knowledge, exploitation of beneficial microbiota and their metabolites to restore pathophysiological balance will likely prove to be an extremely useful remedial tool.
