We studied in vitro platelet aggregation response to serotonin in 19 patients with systemic sclerosis and 18 matched controls. Individuals with early systemic sclerosis had increased % platelet aggregation at 3 minutes over a wide range of serotonin concentrations when compared to individuals with late systemic sclerosis.

A slight, but significant increase of brain serotonin is demonstrated in the striatum encephalopathy: effects of systemic ammonium acetate and L-tryptophan.

burdened by symptoms that might suggest low-grade systemic inflammation, Endurance training in wistar rats decreases receptor sensitivity to a serotonin  Bone health: Serotonin plays a role in bone health. Significantly high levels of serotonin in the bones can lead to osteoporosis, which makes the bones weaker. Serotonin is a chemical your body produces that's needed for your nerve cells and brain to function. But too much serotonin causes signs and symptoms that can range from mild (shivering and diarrhea) to severe (muscle rigidity, fever and seizures). Severe serotonin syndrome can cause death if not treated. The effects of serotonin on cardiac parameters were suppressed either by methysergide or a bilateral section of the cardiac vagus. Bradycardia could then be regarded as the consequence of a vagal mechanism triggered by serotonin action on central methysergide-sensitive serotonergic receptors.

“If neuroscience can be said to have a beginning, one could argue that it occurred in 1954, with the idea that the action of LSD might be related to its effects on the brain serotonin system.” 2. After it became obvious, that serotonin was deeply involved in mental sanity it quickly became the center of attention of pharmaceutical companies.

Sarcoidosis is a systemic disorder characterized by the presence of noncaseating granulomas that are most commonly observed in the lungs. Sarcoid-like reaction has been reported to develop in response to several immune modulator agents and antidepressants. In this report, a case of pulmonary sarcoidosis that was strongly related to the use of more than the average recommended dose of selective

Systemic administration of serotonin at doses of 2, 4, and 8 micrograms/kg body weight/min caused a slight increase in mean arterial blood pressure (1, 4 and 11%), a large decrease in uterine blood flow (10, 37, and 71%) but did not change cardiac output. Serotonin (5-HT), a well-known neurotransmitter in the brain, also plays an important role in peripheral tissues, including the immune system. There is a growing body of evidence suggesting that many different types of immune cells express the machinery to generate, store, respond to and/or transport serotonin, including T cells, macrophages, mast cells, dendritic cells and platelets. Serotonin and lymphocytes Serotonin has dual effects on lymphocyte function and proliferation. Addition of relatively high concentrations of 5-HT to phytohemagglutinin-stimulated lymphocytes suppresses in vitro proliferation.
