TRPV channels as temperature sensors.
The past year has seen a doubling in the number of heat-sensitive ion channels to six, and four of these channels are from the TRPV family. These channels characteristically have Q(10) values of >10 above the thermal threshold, very different from the Q(10) values of 1.5-2.0 seen in most ion channels. Cells expressing TRPV1 show similar temperature sensitivity to small capsaicin-sensitive nocic...
متن کاملHot flash: TRPV channels in the brain.
TRPV1 (transient receptor potential, vanilloid) channels belong to a family of ligand-gated ion channels gated not only by the binding of certain lipophilic molecules but also by extracellular protons and physical stimuli such as heat or osmotic pressure changes. These nonselective cation channels are permeable to Na(+) and K(+) and are also very Ca(2+) permeable; in fact, TRPV1 is as Ca(2+) pe...
متن کاملEndothelial Piezo1 channels as sensors of exercise
Piezo1 channels are newly discovered ion channels which have come to the fore as players in endothelial biology. They have a key role as sensors of shear stress, a frictional force which arises in vascular biology because of blood flow. Endothelial Piezo1 channels are critical in murine embryonic development, just after the heart starts to beat and drive blood into the nascent endothelial netwo...
متن کاملThermally activated TRP channels: molecular sensors for temperature detection.
Temperature sensing is one of the oldest capabilities of living organisms, and is essential for sustaining life, because failure to avoid extreme noxious temperatures can result in tissue damage or death. A subset of members of the transient receptor potential (TRP) ion channel family is finely tuned to detect temperatures ranging from extreme cold to noxious heat, giving rise to thermoTRP chan...
متن کاملTRPV Channels in Mast Cells as a Target for Low-Level-Laser Therapy
Low-level laser irradiation in the visible as well as infrared range is applied to skin for treatment of various diseases. Here we summarize and discuss effects of laser irradiation on mast cells that leads to degranulation of the cells. This process may contribute to initial steps in the final medical effects. We suggest that activation of TRPV channels in the mast cells forms a basis for the ...
