TRPM8

TRPM8

A gene on chromosome 2q37.1 that encodes a receptor-activated, nonselective cation channel involved in detecting of sensations (e.g., low temperatures, when it is activated by temperature < 25ºC). TRPM8 is activated by icilin, eucalyptol, menthol, cold and modulation of intracellular pH.

Camphor activates some of the transient receptor potential (TRP) channels such as TRPV1, TRPV3, TRPM8, and inhibits TRPA1, causing warm sensation, excitation, and desensitization of sensory nerves, relieving the pain, itch and irritation in the applied area.
Specific substances such as Menthol and Camphor are higher in percentage that is 2.6% and 4.73% respectively,1 they attenuate the excitability of nerve membranes and of the specific itch mediating C-fibers and A-fibers.2 Both substances act by attaching to the transient receptor potential (TRP) receptor, but the main mechanism of action by which topical menthol reduces pruritus is by attaching onto the cold receptor TRPM8 which then goes and reaches the A-delta fibers and hence giving a cooling sensation.2 While camphor attaches onto the warm receptor TRPV3.3 Furthermore, menthol also helps in providing general anaesthesia by being a positive modulator of GABA type a receptor.
reported that FA and Z-ligustilide which is another major component of Angelica sinensis, have a synergistic effect on cold-induced vasospasm by regulating cold-sensing proteins TRPM8 and TPRA1 (41).
To find evidence of this adaptation, the researchers took a closer look at TRPM8, a gene that codes for the only known receptor that enables a person to detect and respond to cool and cold temperatures.
