Serotonin release promotion

"Serotonin release promotion" describes any process, intervention, or agent that increases the release of serotonin (5-HT) from intracellular stores (mainly vesicles) into the extracellular space, typically at synaptic clefts in the central nervous system or from enterochromaffin cells in the gut[1][2][5]. This release is central in the regulation of mood, appetite, sleep, vasoconstriction, platelet aggregation, and other physiological processes. While modulation of serotonin release is a pharmacological strategy, serotonin release is itself not a molecule or a canonical drug target but rather the result of modulating specific molecular entities such as serotonin receptors, the serotonin transporter (SERT), or enzymes involved in serotonin biosynthesis (e.g., tryptophan hydroxylase)[1][2][5].
