What is the Origin of Leptin Ghrelin Microbiome?

This term is rooted in the physiological understanding of energy homeostasis, integrating the established roles of leptin (from adipocytes) and ghrelin (from the stomach) with the emerging role of the gut as an endocrine organ. The microbiome is now seen as a critical third partner in this regulatory loop.

What is the Mechanism of Leptin Ghrelin Microbiome?

Gut microbes influence ghrelin and leptin through the production of various metabolites and neuropeptides, particularly short-chain fatty acids (SCFAs) and glucagon-like peptide-1 (GLP-1). SCFAs can directly stimulate the release of satiety-inducing hormones from intestinal enteroendocrine cells. A dysbiotic microbiome can alter the production of these signals, potentially leading to leptin resistance, where the brain fails to register satiety signals effectively, thus driving increased caloric intake and weight gain.

Leptin Ghrelin Microbiome

Meaning

This refers to the complex regulatory triad where the gut microbiome modulates the systemic balance and signaling of the two key appetite-regulating hormones: leptin, which signals satiety, and ghrelin, which signals hunger. The composition of the intestinal flora profoundly influences the efficiency of these neuroendocrine signals, thereby impacting energy balance, body weight regulation, and feeding behavior. Disruptions in this triad are central to the pathogenesis of obesity and metabolic dysregulation.
