肠道菌群调节5-羟色胺影响焦虑行为
- ①压力改变肠道菌群,影响压力激素和脑源性神经营养因子(BDNF),可引起焦虑行为;
- ②肠道中产生的5-羟色胺是一种激素和兴奋性神经递质,在焦虑和抑郁中有重要作用,菌群可调控其在血液和大脑中的水平;
- ③无菌小鼠大脑海马区5-羟色胺及其代谢物5-HIAA、血液色氨酸水平均上升,BDNF和色氨酸代谢生成的犬尿氨酸减少;
- ④菌群介导了海马区5-羟色胺、5-HIAA、BDNF和血液色氨酸的性别差异;
- ⑤幼年期肠道菌群可影响海马区神经发生等神经发育过程。

Abstract:收起
The past decade has yielded substantial evidence that the gut microbiome modulates brain function, including for instance behaviors relevant to anxiety and depression, pointing to a need to identify the biological pathways involved. In 2013 Clarke and colleagues reported that the early-life microbiome regulates the hippocampal serotonergic system in a sex-dependent manner, findings that opened up numerous lines of inquiry on the effects of the microbiome on neurodevelopment and behavior.
