          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 the severity of alcohol drinking

Severe drinking can cause serious morbidity and death. In a double-blind controlled trial randomized 283 alcoholics by genotype in the 5'-regulatory region of the 5-HTT gene (LL/LS/SS), with additional genotyping for another functional single-nucleotide polymorphism (T/G), rs1042173, in the 3'-untranslated region, showed that Individuals with the LL genotype who received ondansetron had a lower mean number of drinks per drinking day (-1.62) and a higher percentage of days abstinent (11.27%) than those who received placebo. Among ondansetron recipients, the number of drinks per drinking day was lower (-1.53) and the percentage of days abstinent higher (9.73%) in LL compared with LS/SS individuals. LL individuals in the ondansetron group also had a lower number of drinks per drinking day (-1.45) and a higher percentage of days abstinent (9.65%) than all other genotype and treatment groups combined. For both number of drinks per drinking day and percentage of days abstinent, 5'-HTTLPR and rs1042173 variants interacted significantly. LL/TT individuals in the ondansetron group had a lower number of drinks per drinking day (-2.63) and a higher percentage of days abstinent (16.99%) than all other genotype and treatment groups combined(26).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and Substance abuse

Serotonin (5-hydroxytryptamine [5-HT]) is an important neurotransmitter implicated in regulating substance-use disorder (SUD) acquisition, maintenance, and recovery. According to the VA Connecticut Healthcare/Yale University School of Medicine, During the past several years, an abundance of research has begun discovering and describing specific 5-HT genetic polymorphisms associated with SUDs. Genetic variations in the 5-HT system, such as SLC6A4, HTR1B, HTR2A, HTR2C, HTR3 (HTR3A, HTR3B, HTR3C, HTR3D, and HTR3E), likely play a role contributing to SUD patient heterogeneity(25).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT)  and carcinoid

There is a report of a 66-year-old woman was diagnosed with hepatic metastasized carcinoid tumor of the ileocecal junction resulting in elevated plasma chromogranin A levels and urinary 5-hydroxyindoleacetic acid (5-HIAA) levels. Further examination showed right-sided heart failure with severe tricuspid valve regurgitation. Carcinoid tumors produce serotonin which leads to flushing, secretory diarrhea, bronchospasm and hypotension, known as carcinoid syndrome. Serotonin is metabolized to 5-HIAA, which is inactive, in the liver and the lungs(24).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT)  in relation to Platelet functions, some hemostatic and fibrinolytic parameters

Erythropoietin corrects anemia and improves hemostasis, but on the other hand bears a risk of thrombotic complications. In the study to evaluate bleeding time, platelet functions and some hemostatic and fibrinolytic parameters in relation to blood and platelet serotonin before and after 1, 2, 4, 8 and 12 weeks of treatment in 22 chronically hemodialyzed patients were administered with human recombinant erythropoietin (rHuEPO) in a dose of 2000 IU s.c. 3 times a week, showed that rHuEPO may improve platelet/vessel wall interactions possibly by means of serotonergic mechanisms. A lowered activity of inhibitors of fibrinolysis may be regarded as a protection against a general tendency to thrombosis during rHuEPO therapy(23).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT) and Fibromyalgia and migraine

In the study of fibromyalgia sufferers randomly administered a combination of monoamine-oxidase inhibitors (MAOIs)-A/B with 5-HTP, 5-HTP alone, MAOIs-A/B alone, or the tricyclic drug amitriptyline in order to compare the efficacy of these treatments, showed that high prevalence of migraine in the population of fibromyalgia sufferers, suggests a common ground shared by fibromyalgia and migraine. Migraine has been demonstrated to be characterized by a defect in the serotonergic and adrenergic systems. A parallel dramatic failure of serotonergic systems and a defect of adrenergic transmission have been evidenced to affect fibromyalgia sufferers too. Enhancing serotonergic analgesia while increasing adrenergically mediated analgesia seems to be an important tool in fibromyalgia(20).

     Hormone Serotonin or 5-hydroxytryptamine (5-HT)  in Cardiovascular effects 

Serotonin causes contraction of most large arteries and veins; it also causes contraction of venules. This is due mainly to direct activation of vascular smooth muscle, although amplification of the response to other endogenous vasoconstrictors (e.g., angiotensin II and norepinephrine) as well as facilitated release of norepinephrine may contribute. In peripheral blood vessels, the receptors mediating the contractions evoked by serotonin belong mainly to the 5-HT2-serotonergic subtype; in the coronary and cerebral arteries, this need not be the case. Vasodilator responses to serotonin are seen mainly at the arteriolar level, but they can also be observed in larger blood vessels. They can be caused by the release of other endogenous vasodilators (e.g., vasoactive intestinal polypeptide), direct relaxation of vascular smooth muscle, inhibition of adrenergic neurotransmission, or production of endothelium-derived relaxing factor(s). The dilator responses to serotonin are mediated by receptors with characteristics similar to 5-HT1-serotonergic binding sites. Aggregating platelets release enough serotonin to evoke both constrictor and dilator responses. The absence of endothelium may change the primary response to aggregating platelets from relaxation to contraction. The responsiveness of the blood vessel wall to serotonin can be augmented acutely by local hypoxia or by cooling(18).
