          Hormone Serotonin or 5-hydroxytryptamine (5-HT) 

Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter derived from tryptophan, primarily found in the gastrointestinal (GI) tract, platelets, and in the central nervous system (CNS). In Gut, serotonin regulates intestinal movements, in CNS, it regulates mood, appetite, sleep, memory and learning, etc.

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and vasoconstrictor synergism

In the study to observe the Contractile synergism between serotonin (5-hydroxytryptamine, 5-HT) and other vasoconstrictor substances in a number of peripheral and cerebrovascular blood vessels, found that this phenomenon may play an important role in certain pathological states such as hypertension, peripheral vascular disease, and coronary spasm. Tthe synergism between serotonin and other vasoconstrictor agents and focus on a recently described type of vasoconstrictor synergism in which precontraction with a non-5-HT receptor agonist yields an enhanced contractile response to serotonin which is mediated by previously inactive or "silent" 5-HT receptor subtypes(14).
