When size matters: transient receptor potential vanilloid 4 channel as a volume-sensor rather than an osmo-sensor

Transient Receptor Potential Vanilloid

Structure-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...

Transient Receptor Potential Vanilloid 1

Background and structure Transient receptor potential vanilloid receptor 1 (TRPV1) is one of 6 members of the subfamily of vanilloid receptors that belongs to the family of transient receptor potential (TRP) channels. TRP channels are an intrinsic part of the mammalian sensory system responding to a broad range of stimuli such as temperature, touch, pain, osmolarity, pheromones, and taste (8). ...

A functional transient receptor potential vanilloid 4 (TRPV4) channel is expressed in human endothelial progenitor cells.

Endothelial progenitor cells (EPCs) are mobilized into circulation to replace damaged endothelial cells and recapitulate the vascular network of injured tissues. Intracellular Ca(2+) signals are key to EPC activation, but it is yet to be elucidated whether they are endowed with the same blend of Ca(2+) -permeable channels expressed by mature endothelial cells. For instance, endothelial colony f...

The transient receptor potential vanilloid 4 channel modulates uterine tone during pregnancy.

The importance of gaining insight into the mechanisms underlying uterine quiescence and contractility is highlighted by the absence of an effective strategy to prevent or treat preterm labor, the greatest cause of perinatal mortality and morbidity worldwide. Although current evidence suggests that in myometrial smooth muscle cells (mSMCs) calcium homeostasis is modulated near term to promote ut...
