Scientists Discover Why We Know When to Stop Scratching an Itch
A newly identified ion channel called TRPV4 acts as the brain's internal braking system for scratching, sending a 'that's enough' signal through sensory neurons. The finding could reshape how researchers develop treatments for chronic itch conditions such as eczema and psoriasis.
Key Takeaways
- Ion channel TRPV4 in sensory neurons acts as a 'stop scratching' signal to the brain
- The same protein triggers itch in skin cells but stops it in neurons — a dual role
