Core Tip
Core Tip: The gut-brain axis is a crucial pathway that links the intestines to the brain and influences host health through microbial metabolites, neural signals, immune responses, and endocrine pathways. Metabolic byproducts of microbes, such as short-chain fatty acids, lipopolysaccharide and bile acids, modulate appetite, emotional regulation, and immune-inflammatory responses via the gut-brain axis and are closely associated with the onset and progression of obesity and depression. Modulating the gut-brain axis, for example, through the use of prebiotics, specific ketogenic diet, and the supplementation of antioxidants, provides new therapeutic strategies for obesity and depression. Future research needs to delve deeper into the mechanisms of the gut-brain axis to develop more effective interventions.
