The molecular and cellular basis of thermosensation in mammals.

Radhika Palkar, Erika K Lippoldt, David D McKemy

Curr. Opin. Neurobiol., 2015 Jan 23 , 34C, 14-19

Over a decade and a half of intensive study has shown that the Transient Receptor Potential family ion channels TRPV1 and TRPM8 are the primary sensors of heat and cold temperatures in the peripheral nervous system. TRPV homologues and TRPA1 are also implicated, but recent genetic evidence has diminished their significance in thermosensation and suggests that a number of newly identified thermosensitive channels, including TRPM3, two-pore potassium channels, and the chloride channel Ano1, require further consideration. In addition to novel thermostransducers, recent genetic and pharmacological approaches have begun to elucidate the afferent neurocircuits underlying temperature sensation, continuing the rapid expansion in our understanding of the cellular and molecular basis of thermosensation that began with the discovery of TRPV1 and TRPM8.
