Hypothalamic signaling controlling energy balance. POMC and AgRP/NPY neurons project from the ARC to the PVN to control food intake and energy balance. The signaling from these neurons can be influenced by GCs, Leptin, and Insulin. ARC, arcuate nucleus; AgRP, agouti-related peptide; GCs, glucocorticoids; GR, glucocorticoid receptor; IR, insulin receptor; LepR, leptin receptor; MC4R, melanocortic 4 receptor; α-MSH, α melanocyte stimulating hormone; NPY, neuropeptide Y; POMC, pro-opiomelanocortin; PVN, paraventricular nucleus; Y1/Y5, Y1 and Y5 receptors; 3V, 3rd Ventricle.
