摘要
Norepinephrine (NE) is a catecholamine neurotransmitter in postganglionic sympatheticnerves and within the central nervous system. In noradrenergic neurons, synaptictransmission includes three stepst release of NE into the synaptic cleft, interaction with apostsynaptic receptor, and subsequent removal from the cleft into pre-synaptic terminals or glialcells. This reaccumulation process is catalyzed by sodium-dependent NE transporter (NET).
