GABAA receptors (GABAARs) are members of the Cys-loop ligand-gated ion channel (LGIC) superfamily, which includes nicotinic acetylcholine, glycine, and serotonin (5HT3) receptors [1,2,3,4]. LGICs typically mediate fast synaptic transmission via the movement of ions through channels gated by neurotransmitters, such as acetylcholine for nicotinic receptors and GABA for GABAARs [5]. The term Cys-loop receptors originates from the presence of a conserved disulphide bond (or bridge) which holds together two cysteine amino acids of the loop that forms from the structure of polypeptides in the extracellular domain of the receptor's subunit [6]...

PURPOSE: To determine the serotonergic (5HT) receptor subtype mediating the contraction of bovine posterior ciliary arteries (BPCAs) in vitro. METHODS: Longitudinal isometric tension was measured in BPCA strips (4-5 mm) mounted in 25 mL organ baths containing oxygenated Krebs solution at 37°C. Cumulative contractile concentration-response (C-R) curves were generated for various 5-HT agonists to assess their potencies and maximal degrees of contraction. Multiple agonist C-R curves were also constructed in the presence and absence of receptor-selective antagonists to determine antagonist potencies using Schild plots...

A series of phenylselanyl-1H-1,2,3-triazole-4-carbonitriles with different substituents were screened for their binding affinity with serotonin transporter (SERT) and dopamine transporter (DAT) by docking molecular. 5-(4methoxyphenyl)-1-(2-(phenylselanyl)phenyl)-1H-1,2,3-triazole-4-carbonitrile (SeTACN) exhibited the best conformation with SERT even higher than fluoxetine and serotonin, suggesting a competitive inhibition. SeTACN demonstrated additional affinity to other serotonergic receptors involved in antidepressant effects: 5HT1a, 5HT2a and 5HT3...

BACKGROUND: Serotonin receptors such as 5-HT3 plays critical role in regulation of sleep, wake cycle and cognitive process. Thus, we investigated the role of CA1 5HT3 serotonin receptors in memory acquisition deficit induced by total sleep deprivation (TSD; for 24 hour) and REM sleep deprivation (RSD; for 24 hour). Pain perception and locomotor activity were also assessed as factors that may affect the memory process. METHODS: Modified water box and multi-platform apparatus were used to induce TSD or RSD, respectively...

BACKGROUND: Irritable bowel syndrome is classified as a functional gastrointestinal disorder with the primary symptom of abdominal pain in conjunction with bloating and bowel movement disorder. It affects up to 15% of the world's population. Among its subtypes, the most common is diarrhoea predominant. However, the current treatment options for diarrhoea-predominant irritable bowel syndrome have had not very promising results; most, such as antispasmodics, only provide partial symptomatic relief...

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) is a troublesome issue in chemotherapy for cancer patients. A second-generation 5HT3 receptor antagonist (5HT3 RA), palonosetron, is effective and safe for the prevention of CINV in breast cancer patients treated with cyclophosphamide and anthracycline, but there is little data for malignant lymphoma. We conducted a prospective phase 2 study at a single institution to clarify the efficacy and safety of palonosetron in lymphoma patients...

INTRODUCTION: Chemotherapy Induced Nausea and Vomiting (CINV) is the most distressing side effect of cancer chemotherapy. It can seriously produce an impact on patient's quality of life. Prevention of CINV is far more effective than treatment of an established CINV. If the patient receives an optimal antiemetic regimen during the initial course of chemotherapy, the likelihood of developing emesis is greatly reduced. Although, all first generation 5HT3 antagonists demonstrate reasonable efficacy in preventing acute CINV, delayed CINV still remains a problem...

This study aimed to assess the effect of intra-habenular injection of morphine on acute trigeminal pain in rats. Also here, we examined the involvement of raphe nucleus opioid and 5HT3 receptors on the antinociceptive activity of intra habenular morphine to explore the possibility of existence of descending antinociceptive relay between the habenula and raphe nucleus. The numbers of eye wiping response elicited by applying a drop (40 μL) of NaCl (5 M) solution on the corneal surface were taken as an index of acute trigeminal nociception...

BACKGROUND: Epilepsy is a syndrome of brain dysfunction caused by spontaneous, abnormal discharge. Many anti-epileptic drugs have developed in past decades. 5-HT is an important neurotransmitter in the central and peripheral nervous system of the human body which is involved in a number of physiological activities, such as sensation, movement, and behavior. 5-HT subtype have been divided into seven sub-groups from 5-HT1 to 5HT7. However, the role of 5-HT3 receptor on epilepsy is unclear...

Depression is a common mental disorder affecting around 350 million people worldwide. Although selective serotonin reuptake inhibitors (SSRIs) are the most widely used antidepressants, a significant proportion of depressed patients do not achieve remission with SSRIs. In this study, we show that a serotonin type 3 receptor (5HT3R) agonist induces antidepressant effects as well as hippocampal neurogenesis independent of fluoxetine (a commonly used SSRI). Notably, our histological analysis reveals that 5HT3R and insulin-like growth factor 1 (IGF1) are expressed in the same neurons in the subgranular zone of the hippocampal dentate gyrus...

Chemotherapy-induced nausea and vomiting (CINV) remains one of the most disturbing side effects of cancer treatment. Research in antiemetic therapy has progressed gradually since the early eighties, and the development of antiemetic agents continues. This review focuses on the current management of CINV based on the most recent guidelines, and adherence to the latter is examined more carefully. Setrons (5HT3 receptor antagonists), corticosteroids, and NK-1 receptor antagonists are the cornerstones of antiemetic therapy...
