TRPM8 encodes the Transient Receptor Potential Melastatin 8 channel, a non-selective calcium-permeable cation channel activated by cold temperatures (below 25°C), menthol, and other cooling agents. TRPM8 is expressed in a subset of sensory neurons (cold-sensitive dorsal root ganglion and trigeminal ganglion neurons) and in some central neurons. Beyond temperature sensation, TRPM8 has been implicated in neurodegeneration through calcium dysregulation, as sustained calcium influx through overactive TRPM8 can trigger apoptotic pathways. In Alzheimer's disease, altered TRPM8 expression may contribute to neuronal calcium dyshomeostasis and pathology progression.
TRPM8 is primarily expressed in:
Expression in the brain is limited but detected in some hypothalamic nuclei involved in thermoregulation.
