Satiety regulation pathway

The **satiety regulation pathway** is not a single molecule or receptor but rather a complex network involving multiple hormones, neurotransmitters, and neural circuits that collectively regulate the sensation of fullness and control food intake. Key components include hypothalamic nuclei such as the arcuate nucleus and ventromedial hypothalamus; peripheral signals like leptin from adipose tissue; insulin from the pancreas; gut-derived peptides such as cholecystokinin (CCK), glucagon-like peptide 1 (GLP‑1), somatostatin; and vagal afferent pathways. These elements interact to balance energy intake with expenditure by modulating hunger and satiety signals at both central and peripheral levels. Disruption in this regulatory network is implicated in diseases such as obesity, diabetes mellitus, metabolic syndrome, and NAFLD[1][2][3]. Drugs targeting individual components—such as GLP‑1 agonists for diabetes/obesity or CCK antagonists for liver disease—modulate specific nodes within this broader physiological system. Note: "Satiety regulation pathway" is not itself a therapeutic target but refers to an integrated physiological process comprising many molecular targets. For structured data purposes it should be flagged as incorrect/not a canonical drug target entity[1][2][3].
