Abstract:

Depression is a neuropsychiatric disease that threatens the physical and mental health of humans worldwide. This study explored the potential anti-depressant effects of ginsenoside Rh4 and its mechanisms of action. The results showed that Rh4 could significantly inhibit depression-like behavior in the depression mouse model and alleviate neuronal damage and hypothalamic-pituitary-adrenal axis disorder. Concurrently, Rh4 inhibits hippocampal neuronal apoptosis and synaptic structural damage due to the overexpression of proinflammatory cytokines and overactivation of microglia and astrocytes by inhibiting the immune-inflammatory response and signaling molecular interaction pathways. Rh4 can also improve intestinal flora and increase the short-chain fatty-acids content. The correlation analysis indicated that the Rh4-inhibited LPS/NLRP3/caspase-1/IL-1βsignaling pathway plays a key role in ameliorating depression. Therefore, this study provides valuable insights into the mode of action of Rh4 on the brain-gut axis in depression, suggesting that Rh4 may be a promising clinical drug for the treatment of depression.
