The effect of neuropeptide Y on brown-like adipocyte's differentiation and activation.

abstract：:Apamin is a neurotoxic octadecapeptide from bee venom, which has been shown to inhibit the non-adrenergic, non-cholinergic inhibitory innervation of the smooth muscle of the gut. Since vasoactive intestinal polypeptide (VIP) has been proposed as a possible inhibitory neurotransmitter, the effect of apamin on the recep...
