In particular, activation of beta-adrenergic receptors (β-ARs) by norepinephrine enhances LTP through downstream engagement of signalling cascades …

Chapter 13 Adrenergic Drugs Affecting the Autonomic Nervous

Webalpha-1 (α 1) adrenergic receptors are G protein-coupled receptors (GPCRs) associated with the G q heterotrimeric G protein. α 1-adrenergic receptors are subdivided into three highly homologous subtypes, i.e., α 1A-, α 1B-, and α 1D-adrenergic receptor subtypes. There is no α 1C receptor. At one time, there was a subtype known as α 1C, but it was … Norepinephrine is stored in these vesicles until it is ejected into the synaptic cleft, typically after an action potential causes the vesicles to release their contents directly into the synaptic cleft through a process called exocytosis. Once in the synapse, norepinephrine binds to and activates receptors.
