Sci. STKE, 8 March 2005 EDITORS' CHOICESENSORY PERCEPTION Skin Feels the HeatUnlike other members of the transient receptor potential (TRP) family of ion channels that function as temperature sensors, TRPV3 is expressed in epithelial keratinocytes rather than sensory neurons in the skin. Moqrich et al. generated a TRPV3 knockout mouse and found that the ion channel is required for animals to detect temperatures in the ambient range. Camphor potentiated the activation of TRPV3 by heat, and mice lacking TRPV3 could not respond to camphor. The study extends thermosensation, once thought to be an exclusive function of neurons, to keratinocytes. A. Moqrich, S. W. Hwang, T. J. Earley, M. J. Petrus, A. N. Murray, K. S. R. Spencer, M.
