Nobel Prize for temperature and touch receptors (2021)
David Julius and Ardem Patapoutian won the Nobel Prize in Physiology or Medicine for discovering TRP channels and Piezo proteins, the molecular sensors that let the body detect heat, cold and touch.
The prize recognized work on sensory transduction that began in the 1990s.
The discoveries opened new targets for pain and touch disorder treatments.
Like optogenetics, the work identified specific proteins that convert physical stimuli into nerve signals, showing how molecular discovery can illuminate whole sensory systems.
