Discovery could pave the way for new treatments for chronic pain in humans, researchers report.
New information about the structure of the TRPA1 protein could help provide new treatments for inflammation induced pain.
Neuroscientists at USC have discovered that carbonated drinks set off the same pain sensors in the nasal cavity as mustard, albeit at a lower intensity. During experimentation, researchers flowed carbonated saline over a dish containing nerve cells taken from the sensory circuits in the nose and mouth. They discovered that the gas activated a specific cell which serve as general pain sensors and expresses the TRPA1 gene.
