The study explores the temperature-dependent gating in cold- and heat-sensitive TRP channels, specifically TRPM8 and TRPV1. It reveals that temperature sensing is closely linked to voltage-dependent gating in these channels. Both TRPM8 and TRPV1 are activated by depolarization, and temperature changes cause graded shifts in their voltage-dependent activation curves. Chemical agonists like menthol (TRPM8) and capsaicin (TRPV1) act as gating modifiers, shifting activation curves toward physiological membrane potentials. Kinetic analysis shows that temperature sensitivity in TRPM8 and TRPV1 arises from a tenfold difference in activation energies for voltage-dependent opening and closing. The study proposes a unifying principle explaining cold and heat sensitivity in TRP channels. TRPM8 is activated by cooling and menthol, while TRPV1 is activated by heating and capsaicin. Both channels exhibit voltage-dependent gating, with temperature affecting their activation curves. TRPM8's cold sensitivity depends on transmembrane voltage, and cooling shifts its activation curve to lower voltages. TRPV1's heat sensitivity also depends on voltage, with heating shifting its activation curve to more physiological voltages. The study uses a two-state model to explain temperature sensitivity, showing that differences in activation energies for opening and closing determine temperature sensitivity. TRPM8's activation energy for closing is much higher than for opening, leading to increased open probability upon cooling. TRPV1's activation energy for opening is much higher than for closing, leading to increased open probability upon heating. The study concludes that temperature sensitivity in TRP channels is governed by the difference in activation energies for voltage-dependent opening and closing.The study explores the temperature-dependent gating in cold- and heat-sensitive TRP channels, specifically TRPM8 and TRPV1.
