The Discovery: Receptors for Temperature and Touch
David Julius: TRPV1 and Temperature Sensation
David Julius utilized capsaicin, the active component in chili peppers, to identify TRPV1, a protein responsible for detecting heat. This discovery revealed how nerve cells detect and respond to high temperatures, forming the foundation for understanding thermal sensation.
Ardem Patapoutian: Piezo Channels and Touch Sensation
Ardem Patapoutian’s work focused on mechanosensitive ion channels, particularly Piezo1 and Piezo2. These channels respond to mechanical stimuli, such as pressure and touch. His findings explained how cells translate physical forces into electrical signals that the nervous system can interpret.
