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]. WebNov 25, 2024 · To improve our understanding of how proinflammatory cytokines affect neural circuits involved in the central regulation of metabolism, we determined whether the membrane excitability of ARH AgRP/NPY and POMC neurons is acutely affected by TNF-α, IL-6, and IL-1β. AgRP and POMC neurons were visualized by Cre-dependent reporter mice.
WebApr 15, 2024 · Despite their opposing actions on food intake, POMC and NPY/AgRP neurons in the arcuate nucleus of the hypothalamus (ARH) are derived from the same progenitors that give rise to ARH neurons. However, the mechanism whereby common neuronal precursors subsequently adopt either the anorexigenic (POMC) or the orexigenic … WebApr 6, 2024 · The insulin receptor (IR) is expressed in both AgRP and POMC neurons.
