          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) in the regulation of emotion processing and mood

Monoamines, such as serotonin, dopamine, and norepinephrine, play a crucial role in the regulation of emotion processing and mood. In the study to investigate how polymorphisms of the serotonin transporter (5-HTT) and catechol-O-methyltransferase (COMT) influence emotion recognition abilities, researchers at the Department of General Psychiatry, Innsbruck Medical University, found that s-allele carriers performed significantly worse in the recognition of happy faces, but did better in the recognition of fearful faces, compared with homozygous l-carriers of the 5-HTT gene. Neither 5-HTT nor COMT genotypes influenced the ability to discriminate between different intensities of sadness or happiness on the PEAT(21).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and the blood vessel wall

Serotonin has complex effects on the cardiovascular system. In the intact animal it may cause increases or decreases of blood pressure and in isolated blood vessels contraction or relaxation depending on the species and vascular bed studied, the route of administration and the dosage used. According to the study by Dr. Vanhoutte PM and Dr. Lüscher TF. serotonin may act indirectly by amplifying the response to norepinephrine and other agonists, by displacing norepinephrine from adrenergic nerve terminals or releasing constrictor substance(s) from the endothelium. Dilatation in response to serotonin is mediated by endothelial and prejunctional S1-serotonergic receptors which pharmacologically resemble 5-HT1-binding sites. In hypertension, constrictor responses to serotonin are augmented, while the vasodilator effects of the monoamine are decreased. The constrictor response to serotonin is increased more than those to other agonists, suggesting a functional rather than a structural adaptation of the hypertensive blood vessel wall. In hypertension the turnover of circulating platelets, the major source of peripheral serotonin, is accelerated and the mechanisms for the removal of the monoamine are impaired. The functional changes of the blood vessel wall and platelets could play a role in the maintenance of the increased peripheral vascular resistance in chronic hypertension, and they could be involved in the pathogenesis of complications of the hypertensive process(17).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and vascular reactivity

In the study of Serotonin causes of contraction of the vascular smooth muscle cells in most blood vessel, found that at low concentrations serotonin amplifies the vasoconstrictor responses to other vasoactive substances. Ultimately the effect of serotonin on vascular constriction is defined by the balance between these different actions. In the intact organism under normal conditions serotonin may play a modulatory role but exacerbation of the contractile effects because of hypersensitivity of the smooth muscle cells, local physical or humoral factors or loss of the relaxatory ability may lead to abnormal tissue responses. Thus, serotonin-induced vasoconstrictor responses may play a role in the etiology of vasospasm and peripheral vascular diseases, in particular at sites of endothelial lesions(16).

The vasodilator effects of serotonin can be caused by (a) inhibiting vascular smooth muscle directly, (b) releasing other inhibitory substances, such as vasoactive intestinal polypeptide, (c) inhibiting adrenergic neurotransmission, and (d) triggering of endothelium-dependent relaxation, according to the study by J Cardiovasc Pharmacol. 1984;6 Suppl 2:S421-8(15).

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).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT)  in Alzheimer's disease

Mounting evidence accumulated over the past few years indicates that the neurotransmitter serotonin plays a significant role in cognition. In the study by Northeast Ohio Medical University researchers indicated that as a drug target, serotonin receptors have received notable attention due in particular to the role of several serotonin-receptor subclasses in cognition and memory. The intimate anatomical and neurochemical association of the serotonergic system with brain areas that regulate memory and learning has directed current drug discovery programmes to focus on this system as a major therapeutic drug target. While many of these compounds will likely find application as adjuvant therapy in the symptomatic treatment of Alzheimer's disease, there are currently only a few drug entities with activity against serotonin receptors that may offer the potential to alter the progression of the disease(12).
