WebThe central melanocortin system is a well-established neuronal pathway involved in regulating energy metabolism. Pro-opiomelanocortin (POMC) neurons, agouti gene … WebIndeed, the activity of POMC and NPY/AgRP neurons is modulated by multiple neurotransmitters and/or hormones. For instance, the anorexigenic effects of serotonin and the adipocyte-derived hormone leptin are considered to be at least in part mediated by excitation of POMC neurons and suppression of NPY/AgRP neurons (3-6).
