Abstract

During the past decade, accumulating evidence from the research highlights the suggested effects of bacterial communities of the human gut microbiota and their metabolites on health and disease. In this regard, microbiota-derived metabolites and their receptors, beyond the immune system, maintain metabolism homeostasis, which is essential to maintain the host's health by balancing the utilization and intake of nutrients. It has been shown that gut bacterial dysbiosis can cause pathology and altered bacterial metabolites' formation, resulting in dysregulation of the immune system and metabolism. The short-chain fatty acids (SCFAs), such as butyrate, acetate, and succinate, are produced due to the fermentation process of bacteria in the gut. It has been noted remodeling in the gut microbiota metabolites associated with the pathophysiology of several neurological disorders, such as Alzheimer's disease, multiple sclerosis, Parkinson's disease, amyotrophic lateral sclerosis, stress, anxiety, depression, autism, vascular dementia, schizophrenia, stroke, and neuromyelitis optica spectrum disorders, among others. This review will discuss the current evidence from the most significant studies dealing with some SCFAs from gut microbial metabolism with selected neurological disorders.

摘要

在过去的十年中,越来越多的研究证据强调了人类肠道微生物群的细菌群落及其代谢产物对健康和疾病的影响。在这方面,微生物衍生的代谢物及其受体(超出免疫系统范围)维持着代谢平衡,这对于通过平衡营养物质的利用和摄入来维持宿主的健康至关重要。已经表明,肠道细菌失调会导致病理改变和细菌代谢物形成的改变,从而导致免疫系统和代谢紊乱。短链脂肪酸(SCFAs),如丁酸盐、乙酸盐和琥珀酸盐,是由于肠道细菌的发酵过程而产生的。已经注意到与几种神经障碍的病理生理学相关的肠道微生物群代谢物的重塑,例如阿尔茨海默病、多发性硬化症、帕金森病、肌萎缩侧索硬化症、压力、焦虑、抑郁、自闭症、血管性痴呆症、精神分裂症、中风和视神经脊髓炎谱系障碍等。本综述将讨论与一些神经障碍相关的来自肠道微生物代谢的特定 SCFAs 的最显著研究的现有证据。
