Scientists have uncovered a hidden \u201cstop-scratching\u201d signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief. In experiments involving chronic itch similar to eczema, mice missing this signal scratched less often\u2014but when they did scratch, they couldn\u2019t stop.<\/p>\n","protected":false},"excerpt":{"rendered":"
