Results Several lines of evidence indicate that 5-HT and
5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems. They mediate both excitatory and inhibitory neurotransmission. Serotonin (5-hydroxytryptamine; 5-HT) is mainly produced from enterochromaffin (EC) cells in gut. • 5-HT plays a key role in secretory and sensorymotor functions in gut. • Changes in gut 5-HT signaling are observed in various gut disorders including inflammatory bowel disease (IBD). •

It is a paracrine messenger utilized by enterochromaffin (EC) cells, which function as sensory transducers.
Serotonin inhibits gastric acid secretion and may be an endogenous enterogastrone. It appears to stimu …. Serotonin is localized in the enterochromaffin
In fact, 90% of the serotonin produced in the body is found in the gut, a neurotransmitter responsible for regulating appetite, mood, sleep, and relaxation. Gut bacteria significantly influences the communication between the brain and the gut.

Abnormalities in this microbiota-gut-brain axis have emerged as a key In the brain, such metabolites may be able to activate receptors on neurons or glia, metabolism along the serotonin (also known as 5-hydroxytryptamine or 5-HT),
Most of our serotonin (approx. 90%) is produced in the gut by special cells, called enterochromaffin (EC) cells, found within the lining of the intestinal wall 3,4. Serotonin (5-hydroxytryptamine or 5-HT) once most extensively studied as a neurotransmitter of the central nervous system, is seen to be predominantly secreted in the gut. Serotonin is an important gastrointestinal signaling molecule.
