regulation of norepinephrine secretion
Definition
Target type: biologicalprocess
Any process that modulates the frequency, rate or extent of the regulated release of norepinephrine. [GOC:ef]
The regulation of norepinephrine secretion is a complex process involving multiple levels of control. It is primarily regulated by the sympathetic nervous system, which responds to various stimuli, including stress, physical activity, and changes in blood pressure.
**1. Presynaptic Regulation:**
* **Action Potentials:** Norepinephrine release is triggered by the arrival of action potentials at the presynaptic terminal of sympathetic neurons. This depolarization opens voltage-gated calcium channels, allowing calcium ions to enter the cell.
* **Calcium Influx:** Calcium acts as a second messenger, triggering the fusion of synaptic vesicles containing norepinephrine with the presynaptic membrane, resulting in exocytosis and the release of norepinephrine into the synaptic cleft.
**2. Receptor-Mediated Regulation:**
* **Presynaptic Autoreceptors:** Norepinephrine itself can bind to presynaptic α2-adrenergic receptors, which act as negative feedback mechanisms to inhibit further norepinephrine release. This autoreceptor activation leads to a decrease in calcium influx and a reduction in exocytosis.
* **Postsynaptic Receptors:** The activation of postsynaptic adrenergic receptors can also influence norepinephrine release indirectly. For instance, the activation of β-adrenergic receptors on the target cell can trigger the release of retrograde messengers that modulate presynaptic activity.
**3. Other Factors:**
* **Neurotransmitters:** Other neurotransmitters, such as acetylcholine, glutamate, and GABA, can influence norepinephrine release. Acetylcholine, for instance, can enhance norepinephrine release through its action on nicotinic receptors.
* **Hormones:** Hormones like cortisol and insulin can also modulate norepinephrine release. Cortisol, a stress hormone, can increase norepinephrine release, while insulin can have an inhibitory effect.
* **Drugs:** Various drugs can either enhance or inhibit norepinephrine release. For example, amphetamines promote norepinephrine release, while β-blockers suppress it.
**4. Postsynaptic Regulation:**
* **Receptor Degradation:** The action of norepinephrine is terminated through reuptake into the presynaptic terminal by a transporter protein (NET) or by enzymatic degradation by enzymes like catechol-O-methyltransferase (COMT) and monoamine oxidase (MAO).
The intricate interplay of these factors ensures the precise regulation of norepinephrine secretion, allowing for appropriate physiological responses to a wide range of stimuli.'
