The skin is the largest human sensory organ. What is not fully understood is how the skin responds to stimuli, especially to pain. Research has now demonstrated that Stem Cell Factor and its receptor, c-Kit, play a central role in tuning the responsiveness of sensory neurons to heat stimuli. “As yet, c-Kit is the first example of a single gene being required for normal noxious heat sensitivity of C-fibers,” according to the neurobiologists.
