Proopiomelanocortin (POMC) neurons in the arcuate nucleus of the hypothalamus represent a critical neuronal population that integrates metabolic, stress, and reward signals to maintain energy homeostasis. These neurons produce multiple neuropeptides including alpha-melanocyte-stimulating hormone (α-MSH), beta-endorphin, and adrenocorticotropic hormone (ACTH), making them central regulators of appetite, metabolism, pain perception, and stress responses. POMC dysfunction has been implicated in obesity, diabetes, neurodegenerative diseases, and metabolic disorders. [1]
The arcuate nucleus (ARC), also known as the infundibular nucleus, is located in the mediobasal hypothalamus adjacent to the third ventricle. It contains two key neuronal populations that balance energy homeostasis: POMC neurons (anorexigenic/satiety-promoting) and neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons (orexigenic/appetite-promoting). The opposing actions of these populations create a homeostatic system for energy balance. [2]
