| Study Title | Untargeted Metabolomics on Mouse colonic mucosa |
| Study Type | Mouse |
| Study Summary | While there is strong evidence for interactions between the microbiota-gut-brain axis and host physiology in the context of chronic stress, limited research has investigated the role of the microbiome in host response to acute stress. Determining the underlying mechanisms by which stress-induced microbiota changes may provoke functional changes in the gut and brain is critical for developing future therapeutics to alleviate the adverse consequences of traumatic stress. Here, we aimed to identify a biological signature of gut metabolites that are significantly altered following exposure to acute restraint stress. Adult male C57Bl/6 conventional, germ-free and colonized germ-free mice underwent a 15-minute restraint stress exposure. Caecal contents were collected from naïve mice and stressed mice, either immediately or 45 minutes following stress. Colonic mucosa underwent untargeted metabolomics analysis. |
