A compelling set of links between the composition of the gut microbiota, the host diet, and host physiology has emerged. Do these links reflect cause-and-effect relationships, and what might be their mechanistic basis? A growing body of work implicates microbially produced metabolites as crucial executors of diet-based microbial influence on the host. Here, we will review data supporting the diverse functional roles carried out by a major class of bacterial metabolites, the short-chain fatty acids (SCFAs). SCFAs can directly activate G-coupled-receptors, inhibit histone deacetylases, and serve as energy substrates. They thus affect various physiological processes and may contribute to health and disease.
肠道微生物群的组成、宿主饮食和宿主生理之间已出现一系列引人注目的联系。这些联系是否反映了因果关系，其机制基础又是什么？越来越多的研究表明，微生物产生的代谢产物是饮食对宿主微生物影响的关键执行者。在这里，我们将回顾支持一类主要细菌代谢产物——短链脂肪酸（SCFA）所发挥的多种功能作用的数据。短链脂肪酸可以直接激活G偶联受体、抑制组蛋白脱乙酰酶并作为能量底物。因此，它们会影响各种生理过程，并可能对健康和疾病产生影响。
