My question is: Is vasoconstriction part of platelet activation? I've read in many articles that it's not part of platelet activation, but precedes it.
Serotonin is an important inflammation mediator and exerts its effects by initiating vasodilation as well as increasing vascular permeability. Molecular regulators of vascular permeability include growth factors and inflammatory cytokines,that is where the serotonin is included. As serotonin is an inflammatory mediator,Acute inflammation can be characterized by vasodilatation, the exudation of protein-rich fluid (plasma), increase of vascular permeability, and cell migration (primarily neutrophil) into the site of inflammation. So, Serotonin is an important inflammation mediator and exerts its effects by initiating vasodilation as well as increasing vascular permeability . Serotonin possesses both vasoconstrictor and vasodilator properties. 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 endogenous vasoconstrictors such as catecholamines, angiotensin II and the prostanoids. (c) release of norepinephrine from adrenergic nerves. Thank you.

Hi! Does serotonin cause increased vascualar permeability due to vasoconstriction? If yes, how exactly? Thanks in advance.
