研究发现,对肠道微生物组的实验操作可以改变啮齿动物的情绪和认知行为、神经递质表达和大脑功能,但相应的人类数据仍然很少。本研究是一项双盲、安慰剂对照的随机研究,旨在研究健康志愿者服用益生菌4周对行为、脑功能和肠道微生物组成的影响。45名健康参与者平均分为三组(益生菌组、安慰剂组和无干预组),接受了功能性核磁共振成像(情绪决策和情绪识别记忆任务)。此外,收集粪便样本以调查肠道微生物组成。服用益生菌4周与情绪记忆和情绪决策任务的大脑激活模式变化有关,这也伴随着肠道微生物群特征的微妙变化。微生物组的组成反映了自我报告的行为测量和记忆表现。这是首次报道益生菌同时对健康志愿者的行为、神经和微生物组水平有明显影响的研究。这些发现为进一步研究肠道菌群的作用和益生菌的潜在治疗应用提供了基础。
Experimental manipulation of the gut microbiome was found to modify emotional and cognitive behavior, neurotransmitter expression and brain function in rodents, but corresponding human data remain scarce. The present double-blind, placebo-controlled randomised study aimed at investigating the effects of 4 weeks’ probiotic administration on behavior, brain function and gut microbial composition in healthy volunteers. Forty-five healthy participants divided equally into three groups (probiotic, placebo and no intervention) underwent functional MRI (emotional decision-making and emotional recognition memory tasks). In addition, stool samples were collected to investigate the gut microbial composition. Probiotic administration for 4 weeks was associated with changes in brain activation patterns in response to emotional memory and emotional decision-making tasks, which were also accompanied by subtle shifts in gut microbiome profile. Microbiome composition mirrored self-reported behavioral measures and memory performance. This is the first study reporting a distinct influence of probiotic administration at behavioral, neural, and microbiome levels at the same time in healthy volunteers. The findings provide a basis for future investigations into the role of the gut microbiota and potential therapeutic application of probiotics.
