Serotonin receptors

Abstract

Although serotonin is produced by a very small number of neurons, it has countless functions in the human body. By affecting the digestive, circulatory, endocrine, urogenital and central nervous systems, it controls such processes as respiration, metabolism, digestion, heart function, vascular contractility, blood homeostasis, micturition, reproduction and behavioral processes. The possible use of excessive or reduced stimulation of serotonin receptors in the treatment of many diseases is at the stage of research. Due to differences in structure, function, action and ligands, 5-HT receptors have been divided into 7 families and at least 15 variants. Most of them belong to the receptors associated with the G protein, 5-HT3 belongs to the ionic receptors.
