Blood platelet and "extra-platelet" serotonin in some myeloproliferative disorders. 1977

J M Culebras Poza, and J M Launay, and J Briere, and C Dreux

Most of the blood serotonin is bound to platelets. However, some authors described plasma "free" serotonin; which is normally very low, and might be increased during some diseases. Usual spectrofluorimetric methods and paired by statistical evaluation "extra-platelet" serotonin (not bound to platelets) in the blood of healthy volunteers and patients with myeloproliferative disorders was studied. In these conditions, we cannot be sure of the existence of "extra-platelets" serotonin in the blood of controls and some patients; in others it was present. "Extra-platelet" serotonin is always present in the blood of untreated patients with primary thrombocytosis.

D009196	Myeloproliferative Disorders	Conditions which cause proliferation of hemopoietically active tissue or of tissue which has embryonic hemopoietic potential. They all involve dysregulation of multipotent MYELOID PROGENITOR CELLS, most often caused by a mutation in the JAK2 PROTEIN TYROSINE KINASE.

D012701	Serotonin	A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.	5-HT,5-Hydroxytryptamine,3-(2-Aminoethyl)-1H-indol-5-ol,Enteramine,Hippophaine,Hydroxytryptamine,5 Hydroxytryptamine
