Abnormal gut microbiome has been associated with depression. The mechanism of probiotics against depression remains unclear. This study aimed to determine whether Clostridium butyricum (Cb) could attenuate chronic unpredictable mild stress-induced depressive-like behavior and its possible mechanisms. Male C57BL/6 mice were subjected to chronic unpredictable mild stress (CUMS) and were treated with Cb. Depressive-like behavior was evaluated by a series of behavioral tests. The levels of cerebral S-hydroxytryptamine (5-HT), brain derived neurotrophic factor (BDNF), glucagon-like peptide-1 (GLP-1) receptor and intestinal were measured. Cb treatment significantly improved CUMS-induced depressive-like behavior in mice. Meanwhile, Cb treatment exhibited prominent effects, increasing S-HT and GLP-1 and upregulating BDNF expression. Furthermore, Cb-treated mice showed increased secretion of GLP-1 and upregulated GLP-1R expression. Taken together, our results demonstrate an antidepressive effect of Cb in CUMS mice partially attributed to stimulation of intestinal GLP-1 secretion and activation of cerebral GLP-1R.
