Effects of Serotonergic Agonists and Antagonists on the Competitive Behaviour of Rats [PDF]

open access: yesRecords of Pharmaceutical & Biomedical Sciences
SWhen  animals  are  housed  in  a  group,  they  form  social  hierarchy,  which  may have a great influence on the cognitive abilities and health of the individuals of this group. The rank order of this social hierarchy may have its consequences on the

Oral morphine induces spinal 5‐hydroxytryptamine (5‐HT) release using an opioid receptor‐independent mechanism

open access: yesPharmacology Research & Perspectives, 2023
Morphine induces spinal 5‐hydroxytryptamine (5‐HT) release, but the role and mechanism of the spinal 5‐HT release induced by morphine are not well understood.

Role of NOX/ROS in 5-HT-mediated proliferation of rat pulmonary artery smooth muscle cells

open access: yesDi-san junyi daxue xuebao, 2020
Objective To observe whether serotonin (5-HT)-mediated proliferation of pulmonary artery smooth muscle cells (PASMCs) is related to the increase of intracellular reactive oxygen species (ROS), and identify the role of NADPH oxidase (NOX) in the ...

Skin Vascular Resistance Decreases during 5-HT-Induced Hypotension in the Rat

open access: yesBiomedicines, 2023
A recognized vasodilator, the infusion of 5-hydroxytryptamine (5-HT, serotonin) decreases blood pressure through the reduction of total peripheral resistance in the rat. It is not clear which vascular beds/tissues are responsible for this fall.

5-hydroxytryptamine (5-HT) cellular sequestration during chronic exposure delays 5-HT3 receptor resensitization due to Its subsequent release [PDF]

open access: yes, 2014
The serotonergic synapse is dynamically regulated by serotonin (5-hydroxytryptamine (5-HT)) with elevated levels leading to the down-regulation of the serotonin transporter and a variety of 5-HT receptors, including the 5-HT type-3 (5-HT3) receptors.

Enterochromaffin 5-HT cells – A major target for GLP-1 and gut microbial metabolites

open access: yesMolecular Metabolism, 2018
Objectives 5-HT storing enterochromaffin (EC) cells are believed to respond to nutrient and gut microbial components, and 5-HT receptor-expressing afferent vagal neurons have been described to be the major sensors of nutrients in the GI-tract.

5-ht inhibition of rat insulin 2 promoter cre recombinase transgene and proopiomelanocortin neuron excitability in the mouse arcuate nucleus [PDF]

open access: yes, 2009
A number of anti-obesity agents have been developed that enhance hypothalamic 5-HT transmission. Various studies have demonstrated that arcuate neurons, which express proopiomelanocortin peptides (POMC neurons), and neuropeptide Y with agouti-related ...

Constitutively active 5-HT receptors: An explanation of how 5-HT antagonists inhibit gut motility in species where 5-HT is not a enteric neurotransmitter ?

open access: yesFrontiers in Cellular Neuroscience, 2015
Antagonists of 5-Hydroxytryptamine (5-HT) receptors are well known to inhibit gastrointestinal (GI)-motility and transit in a variety of mammals, including humans.

Inhibition of native 5-HT3 receptor-evoked contractions in Guinea pig and mouse ileum by antimalarial drugs [PDF]

open access: yes, 2014
Quinine, Chloroquine and mefloquine are commonly used to treat malaria; however with associated gastrointestinal (GI) side-effects. These drugs act as antagonists at recombinant 5-HT3 receptors and modulate gut peristalsis.

Ritanserin as an adjunct to lithium and haloperidol for the treatment of medication-naive patients with acute mania: a double blind and placebo controlled trial

open access: yesBMC Psychiatry, 2003
Background Bipolar disorder is a lifelong episodic condition characterized by mood swings between mania and depression. Several lines of evidence suggest that serotonin is likely to play a pivotal role in the pathophysiology of bipolar disorder ...
