Overall design | The aim of this study was to explore the unique characteristics and pathophysiological mechanisms of adolescent depression from a microbiota-gut-brain axis perspective. Male cynomolgus macaques (Macaca fascicularis) were divided into the following 2 groups (n = 5 in each group): (1) control group, and (2) CUMS group. The CUMS group was exposed to seven days of CUMS stress followed by a four-day behavior observation period; this regimen was conducted for five cycles. The metabolite profiles of microbiota-gut-brain axis including central (prefrontal cortex, hippocampus, and amygdala) and peripheral (plasma, gut and feces of cecum, ascending colon, transverse colon, and descending colon) samples were analyzed by metabolomic profiling. |
