Norepinephrine, also known as noradrenaline, is a chemical made by some nerve cells and in the adrenal gland. It can function as both aneurotransmitter(a chemical messenger used by nerve cells) and a hormone (a chemical that travels in the blood and controls the actions of other cells or or...
Norepinephrine (NE) concentration (pmol NE per g or mg wet weight), in the thymus from AA rats was significantly increased. Conversely, a significant decrease in splenic and lymph node NE concentration was measured in adjuvant-treated animals compared with that seen in vehicle-treated rats. ...
The effect of supramaximal electric field stimulation on 3H released from rat spleen strips was studied after loading with either [3H]dopamine ([3H]DA) or [3H]norepinephrine ([3H]NE). In some experiments, [3H]DA and [3H]NE stored in the tissue or released in response to electrical stimul...

Background: Norepinephrine (NE) is released from its storag e granules when the nerve is stimulated and enters the synaptic cleft to bind to alpha and beta-receptors on the effector cells. Chemical signaling is terminated by a rapid reuptake of neurotransmitter into presynaptic nerve terminals ...
