Use of a fluorescent imaging plate reader--based calcium assay to assess pharmacological differences between the human and rat vanilloid receptor.
The cloned vanilloid receptor 1 (VR1) is a ligand-gated calcium channel that is believed to be the capsaicin-activated vanilloid receptor found in native tissues, based on similarities regarding molecular mass, tissue distribution, and electrophysiological properties. Using a Fluorescent Imaging Plate Reader (FLIPR), along with Fluo-3 to signal intracellular calcium levels ([Ca(++)](i)), rat VR...
متن کاملComparison of effects of anandamide at recombinant and endogenous rat vanilloid receptors.
BACKGROUND Anandamide, an endogenous lipid, activates both cannabinoid (CB(1)) and vanilloid (VR1) receptors, both of which are co-expressed in rat dorsal root ganglion (DRG) cells. Activation of either receptor results in analgesia but the relative contribution of CB(1) and VR1 in anandamide-induced analgesia remains controversial. Here we compare the in vitro pharmacology of recombinant and e...
متن کاملBiochemical pharmacology of the vanilloid receptor TRPV1. An update.
There is mounting evidence that the vanilloid (capsaicin) receptor; transient receptor potential channel, vanilloid subfamily member 1 (TRPV1), is subjected to multiple interacting levels of control. The first level is by reversible phosphorylation catalyzed by intrinsic kinases (e.g. protein kinase A and C) and phosphatases (e.g. calcineurin), which plays a pivotal role in receptor sensitizati...
متن کاملStructure-Driven Pharmacology of Transient Receptor Potential Channel Vanilloid 1.
The transient receptor potential vanilloid 1 (TRPV1) ion channel is a polymodal receptor that mediates the flux of cations across the membrane in response to several stimuli, including heat, voltage, and ligands. The best known agonist of TRPV1 channels is capsaicin, the pungent component of "hot" chili peppers. In addition, peptides found in the venom of poisonous animals, along with the lipid...
متن کاملPharmacology of vanilloid transient receptor potential cation channels.
Depending on their primary structure, the 28 mammalian transient receptor potential (TRP) cation channels identified so far can be sorted into 6 subfamilies: TRPC ("Canonical"), TRPV ("Vanilloid"), TRPM ("Melastatin"), TRPP ("Polycystin"), TRPML ("Mucolipin"), and TRPA ("Ankyrin"). The TRPV subfamily (vanilloid receptors) comprises channels critically involved in nociception and thermosensing (...
