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. WebApr 11, 2024 · Herein we described how an NPY/AgRP-expressing cell line secretes sEVs that appear to have a functional impact on a Pomc-expressing cell line. It was already known that NPY/AgRP neurons directly inhibit POMC neurons through binding of NPY to the Y 1 receptor and through secretion of GABA (Roseberry et al., 2004). oran twin wall
