Supercooling Agent Icilin Blocks a Warmth-Sensing Ion Channel TRPV3

Transient receptor potential vanilloid subtype 3 (TRPV3) is a thermosensitive ion channel expressed in a variety of neural cells and in keratinocytes. It is activated by warmth (33-39°C), and its responsiveness is dramatically increased at nociceptive temperatures greater than 40°C. Monoterpenoids and 2-APB are chemical activators of TRPV3 channels. We found that Icilin, a known cooling substan...

Warmth suppresses and desensitizes damage-sensing ion channel TRPA1

BACKGROUND Acute or chronic tissue damage induces an inflammatory response accompanied by pain and alterations in local tissue temperature. Recent studies revealed that the transient receptor potential A1 (TRPA1) channel is activated by a wide variety of substances that are released following tissue damage to evoke nociception and neurogenic inflammation. Although the effects of a noxious range...

Oxygen-dependent hydroxylation by FIH regulates the TRPV3 ion channel.

Factor inhibiting HIF (FIH, also known as HIF1AN) is an oxygen-dependent asparaginyl hydroxylase that regulates the hypoxia-inducible factors (HIFs). Several proteins containing ankyrin repeat domains (ARDs) have been characterised as substrates of FIH, although there is little evidence for a functional consequence of hydroxylation on these substrates. This study demonstrates that the transient...

Ion conduction and selectivity in acid-sensing ion channel 1

The ability of acid-sensing ion channels (ASICs) to discriminate among cations was assessed based on changes in conductance and reversal potential with ion substitution. Human ASIC1a was expressed in Xenopus laevis oocytes, and acid-induced currents were measured using two-electrode voltage clamp. Replacement of extracellular Na(+) with Li(+), K(+), Rb(+), or Cs(+) altered inward conductance an...

Biphasic currents evoked by chemical or thermal activation of the heat-gated ion channel, TRPV3.

2-Aminoethyl diphenylborinate was recently identified as a chemical activator of TRPV1, TRPV2, and TRPV3, three heat-gated members of the transient receptor potential vanilloid (TRPV) ion channel subfamily. Here we demonstrated that two structurally related compounds, diphenylboronic anhydride (DPBA) and diphenyltetrahydrofuran (DPTHF), can also modulate the activity of these channels. DPBA act...
