Four or five biological sets of CETSA-independent experiments were carried out, with experiments conducted on different days. Errors are in SEM. (C) Patch-clamp electrophysiology of TRPM8 in the absence (top) and presence (bottom) of the cognate TRPM8 agonist menthol (500 μM) indicates that it is a functional ion channel. These trafficking . The transient receptor potential ankyrin 1 (TRPA1) ion channel is expressed in nociceptive neurons and its activation causes ongoing pain and inflammation; TRPA1 is thought to play an important role in inflammation in the airways. . 2007), while non‐electrophilic agonists such as menthol activate by binding to a site within transmembrane .Moreover, many of these channels are receptors for ligands that elicit distinct psychophysical sensations, such as the heat associated with capsaicin and the cold felt with menthol. The latter of these was influential in the discovery of the first TRP channel shown to be responsive to temperatures in the cold range (<30°C), TRPM8, a member of . Menthol was also found to inhibit nicotinic acetyl choline receptors, and serotonin-gated ion channels, known to contribute to pain signaling [22,24]. In addition to the lack of selectivity, the contradictory outcomes of the above studies may have resulted from the use of different stereoisomers of menthol [27].
Thermosensation requires the activation of a unique collection of ion channels and receptors that work in concert to transmit thermal information. It is widely accepted that transient receptor potential melastatin 8 (TRPM8) activation is required for normal cold sensing; however, recent studies have illuminated major roles for other ion . The effects of deep rapid and slow cooling with decrease in rectal temperature by 3 °C, and activation of the skin TRPM8 ion channel by its agonist menthol (application of 1% L-menthol) on the concentration of pro-inflammatory cytokines (IL-6, IL-1β and TNFα) in blood have been studied. The data have shown that the TRPM8 ion channel . Four or five biological sets of CETSA-independent experiments were carried out, with experiments conducted on different days. Errors are in SEM. (C) Patch-clamp electrophysiology of TRPM8 in the absence (top) and presence (bottom) of the cognate TRPM8 agonist menthol (500 μM) indicates that it is a functional ion channel. These trafficking . Menthol, an agonist of the cold sensitive TRPM8 ion channel, decreased the temperature thresholds of all thermoregulatory responses induced by rapid and slow cooling without affecting the sequence .

TRPM8: Transient receptor potential melastatin 8, TRPM8, is an excitatory ion channel receptor and a member of the TRP family. Menthol receptor is nonselective and polymodal ion channel which opens through chemical agonists, for example, menthol, cool and cold temperatures (8–28°C), and voltage. Menthol in mints elicits coolness sensation by selectively activating TRPM8 channel. Although structures of TRPM8 were determined in the apo and liganded states, the menthol-bounded state is unresolved. To understand how menthol activates the channel, we docked menthol to the channel and systematica . trans-Anethole of Fennel Oil is a Selective and Nonelectrophilic Agonist of the TRPA1 Ion Channel. Tosifa Memon, Oleg Yarishkin, Christopher A. Reilly, David Križaj, . However, nonelectrophilic TRPA1 agonists such as menthol and propofol interact with Ser-873 and Thr-874 residues located in transmembrane five of TRPA1 .
Transient receptor potential melastatin-8 (TRPM8), a cationic ion channel is involved in detection of normal cooling-sensation in mammals. TRPM8 activation by cooling or chemical agonists have . Genetically labelled sensory neurons of TRPM8 BAC-EYFP mice are cold and menthol sensitive. To identify sensory neurons expressing the TRPM8 channel in vivo, we used a genetic strategy.A bacterial artificial chromosome (BAC) containing the entire mouse TRPM8 locus was modified by inserting the cDNA encoding for the enhanced yellow fluorescent . Menthol in mints elicits a coolness sensation by selective activation of TRPM8 ion channel. Here authors dock menthol to TRPM8 and systematically validate their menthol binding models with .
The identification of TRPM8 and the subsequent studies characterizing its properties have shed light on the molecular mechanisms of cold sensation. Future studies will undoubtedly continue to elucidate the biological importance of this ion channel in mediating sensory signaling, as well as the role of TRPM8 in nonneuronal tissues.
Effects of menthol on ion channels. Ion channels are pore-forming integral membrane proteins that regulate the transfer of charged ions (Ca 2+, K +, Na +, or Cl −) through the bilayer membrane of the cell and regulate resting membrane potential, action potentials and other electrical signals. Channel opening is usually triggered by a specific .The TRPM8 channel is a homotetramer, composed of four identical subunits with a transmembrane domain with six helices (S1–6). The first four, S1–4, act as the voltage sensor and allow binding of menthol, icilin and similar channel agonists. Transient receptor potential melastatin (TRPM) ion channels constitute the largest TRP subfamily and are involved in many physiological processes. TRPM8 is the primary cold and menthol sensor, and TRPM4 is associated with cardiovascular disorders. Menthol in mints elicits coolness sensation by selectively activating TRPM8 channel. Although structures of TRPM8 were determined in the apo and liganded states, the menthol-bounded state is unresolved.
Transient receptor potential melastatin 8 (TRPM8) is a temperature- and menthol-sensitive ion channel that contributes to diverse physiological roles, including cold sensing and pain perception.Ion channel mechanisms of rat tail artery contraction-relaxation by menthol involving, respectively, TRPM8 activation and L-type Ca2+ channel inhibition. Am. J. Menthol may act by affecting agonist binding or the closing of inhibitory ligand-gated ion channels at predominantly postsynaptic receptor sites, but TRPM8 receptors are not thought to be involved (Hall et al., 2004).
