Summary

Story summary

Researchers identify TRPV4 as a key regulator of itch, initiating and relieving the sensation.
Neuroscientist Roberta Gualdani will present at the Biophysical Society meeting in San Francisco on February 24.
The study in genetically engineered mice shows that TRPV4-lacking subjects scratch less often but have longer bouts.
The findings suggest potential treatments for eczema, but manipulating TRPV4 could increase itch or hinder relief.
