Identifying the Principal Protein Sensor for Touch

Sense of Touch Research

A team led by biologists at The Scripps Research Institute (TSRI) has solved a long-standing mystery in neuroscience by identifying the “mechanoreceptor” protein that mediates the sense of touch in mammals. Mice that lack the Piezo2 ion-channel protein in their skin cells and nerve endings lose nearly all their sensitivity to ordinary light touch, but retain a mostly normal sensitivity to painful mechanical stimuli.
