This counter-regulatory response is mediated by the steroidogenic-factor 1 … WebNPY/AgRP neurons and POMC/CART neurons make up two groups of neurons in the arcuate nucleus that are centrally involved in the neuroendocrine function of feeding. Medial neurons utilize NPY peptides as neurotransmitters to stimulate appetite, and lateral neurons utilize POMC/CART to inhibit appetite. [2]

WebNov 13, 2012 · As in the case of leptin, POMC and AgRP neurons are supposed to be crucial targets of insulin signalling. It has been shown that insulin acts on these subsets of neurons, as shown by the fact that its central administration provokes hyperpolarization of both POMC and AgRP neurons in the Arc [17, 29, 45, 54].
