Central Serotonin Receptor Subtypes - An Overview

Opioid receptor subtypes differentially modulate serotonin efflux in the rat central nervous system.

Opioid receptor subtypes may have site-specific effects and play different roles in modulating serotonergic neurotransmission in the mammalian central nervous system. To test this hypothesis, we used in vivo microdialysis to measure changes in extracellular serotonin (5-hydroxytryptamine; 5-HT) in response to local infusion of mu-, delta-, and kappa-opioid receptor ligands into the dorsal raphe...

An Overview of Achalasia and Its Subtypes.

Achalasia is one of the most studied esophageal motility disorders. However, the pathophysiology and reasons that patients develop achalasia are still unclear. Patients often present with dysphagia to solids and liquids, regurgitation, and varying degrees of weight loss. There is significant latency prior to diagnosis, which can have nutritional implications. The diagnosis is suspected based on...

Fas Receptor: An Overview

The FAS receptor (FasR), also known as apoptosis antigen 1 (APO-1 or APT), cluster of differentiation 95 (CD95) or tumor necrosis factor receptor superfamily 6 (TNFRSF6) is a protein that in humans is encoded by the FAS gene. Engagement of the cell death surface receptor Fas by Fas ligand (FasL) results in apoptotic cell death, mediated by caspase activation. Cell death mediated via Fas/FasL in...

The Effects of Selective Serotonin Reuptake Inhibitors on the Function of Distinct Serotonin Receptor Subtypes in the Rat

A paracrine signaling role for serotonin in rat taste buds: expression and localization of serotonin receptor subtypes.

Recent advances in peripheral taste physiology now suggest that the classic linear view of information processing within the taste bud is inadequate and that paracrine processing, although undemonstrated, may be an essential feature of peripheral gustatory transduction. Taste receptor cells (TRCs) express multiple neurotransmitters of unknown function that could potentially participate in a par...
