Title

Gut microbiome remodeling induces depressive-like behaviors through a pathway mediated by the host's metabolism

Overall design

In this study, we initially assessed how gut microbiota physiologically influence the psychobehavioral characteristics of germ-free (GF) and SPF mice. To assess whether alterations of gut microbiota have a causal role in depression-like behavior, gut microbiome remodeling was accomplished through fecal microbiota transplantation (FMT) from either major depressive disorder patients or healthy individuals on GF mice followed by behavioral testing to assess depression-like behaviors. Metabolomic analyses of samples from the mice harboring 'depression microbiota' were conducted to examine how the gut microbiome influences host metabolism. GF Mice were divided into the following 2 groups (n = 10 in each group): (1) control group (fecal microbiota transplantation with fecal sample from healthy controls), (2) depressed group (fecal microbiota transplantation with fecal sample from major depression patients). On week 2 post FMT, the depressed and control mice were killed, and cecum, serum and hippocampus samples were obtained. These samples were subsequently extracted and analyzed by gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and nuclear magnetic resonance.
