The constrictor action of the monoamine can be due to: (a) direct activation of vascular smooth muscle; in most blood vessels, this is mediated by S2-serotonergic receptors; (b) augmentation (amplification) of the action of other e … 13.09.13 Serotonin Receptors. Seven serotonin receptor subtypes have been identified, 5-hydroxytryptamine (5-HT)1 through 5-HT7, and most of these are metabotropic except for 5-HT3, which is a ligand-gated ion channel. These are nonselective cation channels mediating excitatory transmission.

Metoclopramide and the 5-HT(4) receptor agonist cisapride were found to activate catecholamine- and granin-derived peptide secretions by cultured tumor cells.

The secreted ADP binds to the P2Y 12 receptor, which leads to a downstream conformational change in the GPIIb/IIIa molecule that converts it from a low-affinity receptor to a high-affinity Ergot Alkaloids.
