Why Mint Tastes Cold
Why does toothpaste, chewing gum and peppermint feel cold? These products are no colder than the ambient temperature around us, but they contain a chemical called L-menthol that tricks our body's TRPM8 temperature receptors. This is why mint tastes cold, and why minty products make cold things feel even colder. Some music by: X I X X: https://soundcloud.com/jeff-kaale
TRPM8 is a neuronal osmosensor that regulates eye blinking in mice. Talisia Quallo et al (2015), Nature Communications http://dx.doi.org/10.1038/ncomms8150 Specific peripheral sensory neurons respond to increases in extracellular osmolality but the mechanism responsible for excitation is unknown. Here we show that small increases in osmolality excite isolated mouse dorsal root ganglion (DRG) and trigeminal ganglion (TG) neurons expressing the cold-sensitive TRPM8 channel (transient receptor potential channel, subfamily M, member 8). Hyperosmotic responses were abolished by TRPM8 antagonists, and were absent in DRG and TG neurons isolated from Trpm8−/− mice. Heterologously expressed TRPM8 was activated by increased osmolality around physiological levels and inhibited by reduced osmolality....
VAMP7 regulates constitutive membrane incorporation of the cold-activated channel TRPM8. Debapriya Ghosh et al (2016), Nature Communications http://dx.doi.org/10.1038/ncomms10489 The cation channel TRPM8 plays a central role in the somatosensory system, as a key sensor of innocuously cold temperatures and cooling agents. Although increased functional expression of TRPM8 has been implicated in various forms of pathological cold hypersensitivity, little is known about the cellular and molecular mechanisms that determine TRPM8 abundance at the plasma membrane. Here we demonstrate constitutive transport of TRPM8 towards the plasma membrane in atypical, non-acidic transport vesicles that contain lysosomal-associated membrane protein 1 (LAMP1), and provide evidence that vesicle-associated membr...

More specifically, menthol binds with cold-sensitive receptors in your skin; these receptors contain things called “i...
