The gut microbiota plays a potential role in the pathophysiology of depression through the gut-brain axis. This cross-sectional study in 400 participants from the PREDIMED-Plus study investigates the interplay between gut microbiota and depression using a multi-omics approach. Depression was defined as antidepressant use or high Beck Depression Inventory-II scores. Gut microbiota was characterized by 16S rRNA sequencing, and faecal metabolites were analysed via liquid chromatography-tandem mass spectrometry. Participants with depression exhibited significant differences in gut microbial composition and metabolic profiles. Differentially abundant taxa included Acidaminococcus, Christensenellaceae R-7 group, and Megasphaera, among others. Metabolomic analysis revealed 15 significantly altered metabolites, primarily lipids, organic acids, and benzenoids, some of which correlated with gut microbial features. This study highlights the interplay between the gut microbiota and depression, paving the way for future research to determine whether gut microbiota influences depression pathophysiology or reflects changes associated with depression.
肠道微生物群通过肠-脑轴在抑郁症的病理生理学中发挥潜在作用。这项针对PREDIMED-Plus研究中400名参与者的横断面研究,采用多组学方法研究肠道微生物群与抑郁症之间的相互作用。抑郁症定义为使用抗抑郁药或贝克抑郁量表-II得分较高。通过16S rRNA测序对肠道微生物群进行表征,并通过液相色谱-串联质谱法分析粪便代谢物。患有抑郁症的参与者在肠道微生物组成和代谢谱方面表现出显著差异。差异丰富的分类群包括氨基酸球菌、克里斯滕森菌科R-7组和巨球形菌等。代谢组学分析揭示了15种显著改变的代谢物,主要是脂质、有机酸和苯类化合物,其中一些与肠道微生物特征相关。这项研究突出了肠道微生物群与抑郁症之间的相互作用,为未来研究确定肠道微生物群是否影响抑郁症病理生理学或反映与抑郁症相关的变化铺平了道路。
