DNA methylation of the serotonin transporter gene in peripheral cells and stress-related changes in hippocampal volume: a study in depressed patients and healthy controls.

PLoS ONE, 2015
Serotonin plays an important role in the etiology of depression. Serotonin is also crucial for brain development. For instance, animal studies have demonstrated that early disruptions in the serotonin system affect brain development and emotion ...

Serotonin: beyond menopause [PDF]

Romanian Journal of Medical Practice, 2016
Serotonin is a brain neurotransmitter, a local gut-produced pro-kinetic agent and a platelets-released monoamine with haemostasis role. We focus on revealing the serotonin interferences with menopause mainly related to climacteric syndrome and bone ...

Serotonin system in the human placenta – the knowns and unknowns

Frontiers in Endocrinology, 2022
The biogenic monoamine serotonin (5-hydroxytryptamine, 5-HT) is a chemical messenger widely distributed in the brain and various other organs. Its homeostasis is maintained by the coordinated activity of a variety of proteins, including enzymes of ...

Enhanced sensitivity of postsynaptic serotonin-1A receptors in rats and mice with high trait aggression [PDF]

, 2001
Individual differences in aggressive behaviour have been linked to variability in central serotonergic activity, both in humans and animals. A previous experiment in mice, selectively bred for high or low levels of aggression, showed an up-regulation of ...

Identification, functional characterization and pharmacological profile of a serotonin type-2b receptor in the medically important insect, Rhodnius prolixus

Frontiers in Neuroscience, 2015
In the Chagas disease vector, Rhodnius prolixus, two diuretic hormones act synergistically to dramatically increase fluid secretion by the Malpighian tubules (MTs) during the rapid diuresis that is initiated upon engorgement of vertebrate blood.

Serotonin signaling regulates actomyosin contractility during morphogenesis in evolutionarily divergent lineages

Nature Communications, 2023
Serotonin is a neurotransmitter that signals through 5-HT receptors to control key functions in the nervous system. Serotonin receptors are also ubiquitously expressed in various organs and have been detected in embryos of different organisms.

Interaction between Intestinal Microbiota and Serotonin Metabolism

Journal of Mazandaran University of Medical Sciences, 2021
Gut microbiota regulates the production of signaling molecules, such as serotonin or 5-Hydroxytryptamine: 5-HT in the host. Serotonin is a biogenic amine that acts as a neurotransmitter in the gut and brain.

Biological clocks in the duodenum and the diurnal regulation of duodenal and plasma serotonin. [PDF]

PLoS ONE, 2013
Serotonin in blood plasma is primarily synthesized in the duodenum, as brain derived serotonin does not cross the blood-brain barrier. Because serotonin in the brain and retina is synthesized under the control of a circadian clock, we sought to determine
