去甲肾上腺素(NE)是儿茶酚胺类递质的一种,存在于节后交感神经和中枢神经系统内.在去甲肾上腺素能神经元中,突触传递包括3个步骤:NE由突触前膜释放到突触间隙;间隙中的NE与突触后膜上的受体作用;接着NE被突触前神经元或胶质细胞重新吸收.NE再摄取的过程需要钠离子依赖性的去甲肾上腺素转运蛋白(NET)参与.NET是一类药物的作用
Norepinephrine (NE) is a catecholamine neurotransmitter present in the sympathetic and central nervous systems of the node.Nasynaptic neurons comprise three steps in the synaptic transmission: the NE consists of synapses Pre-membrane release to the synaptic cleft; NE in the interstitium acts on receptors on the postsynaptic membrane; NEs are then reabsorbed by presynaptic neurons or glia. NE reuptake requires sodium ion-dependent Norepinephrine transporter (NET) participation in .NET is a class of drugs
