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]. WebJan 15, 2024 · However, AgRP neuropeptides are also responsible for sustaining long-term feeding actions, as compared to NPY (Krashes et al., 2013). AgRP neurons inhibit POMC neurons by antagonistic actions of GABA and NPY, whilst sending collateral projections to many different brain regions that correspond with POMC projections (Wu and Palmiter, …

WebApr 14, 2024 · NPY/AgRP and POMC/CART neurons in the ARC form a network of fibers projecting to various regions. Leptin functions through its receptors to stimulate neurons producing POMC. POMC is further cleaved to α-MSH, a neuropeptide signaling through MC4R and MC3R to evoke anorexigenic effects on food intake and energy expenditure. WebAbstract. Two classes of peptide-producing neurons in the arcuate nucleus (Arc) of the hypothalamus are known to exert opposing actions on feeding: the anorexigenic neurons …
