WebDec 1, 2014 · The actions of AgRP and POMC neurons are brought about by projections to other brain sites, one notable structure being the paraventricular nucleus (Figure 3). MC4R-expressing neurons, a subset of the neurons in this complex neural hub, play a major role in mediating the effects of the melanocortin system on hunger.

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]. WebSep 1, 2024 · Among central targets of leptin signaling, AgRP and POMC neurons are the best studied. In contrast to POMC neurons, which are directly depolarized by leptin [], …
WebDec 15, 2024 · Furthermore, AgRP and POMC neurons are reciprocally regulated by leptin (Schwartz et al., 2000; Sohn et al., 2013) and other humoral signals, such that the effect of energy restriction to reduce body fat stores (and plasma leptin levels) causes both activation of AgRP neurons and inhibition of POMC neurons, a combined response that drives ... 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).
