Merkel Cell Count With Old Age May Correspond To Increased Feelings Of Itchiness, Mouse Study Suggests.

Science Magazine (5/3, Underwood) reports a new study suggests that people tend to experience increased feelings of itchiness with age, or alloknesis, because of "a loss of pressure-sensing cells in the skin." In mice, researchers observed "that older mice had far fewer pressure-sensing Merkel cells than young mice did," determining that the "fewer Merkel cells a mouse had, the more their touch-related itch problems increased in response to the filament." Mark Hoon, a neuroscientist at the National Institute of Dental and Craniofacial Research, is paraphrased as saying that research still has not indicated "where the mechanical itch signals come from in the first place." He is quoted as saying, "One is left wondering how it all fits together."
