2021-10-04 The Nobel Assembly at Karolinska Institutet has today decided to award the 2021 Nobel Prize in Physiology or Medicine jointly to David Julius and Ardem Patapoutian for their discoveries of receptors for temperature and touch Our ability to sense heat, cold and touch is essential for survival and underpins our interaction with the world a...
One of the great mysteries facing humanity is the question of how we sense our environment. The mechanisms underlying our senses have triggered our curiosity for thousands of years, for example, how light is detected by the eyes, how sound waves affect our inner ears, and how different chemical compounds interact with receptors in our nose and mout...
In the latter part of the 1990’s, David Julius at the University of California, San Francisco, USA, saw the possibility for major advances by analyzing how the chemical compound capsaicin causes the burning sensation we feel when we come into contact with chili peppers. Capsaicin was already known to activate nerve cells causing pain sensations, bu...
While the mechanisms for temperature sensation were unfolding, it remained unclear how mechanical stimuli could be converted into our senses of touch and pressure. Researchers had previously found mechanical sensors in bacteria, but the mechanisms underlying touch in vertebrates remained unknown. Ardem Patapoutian, working at Scripps Research in La...
The groundbreaking discoveries of the TRPV1, TRPM8 and Piezo channels by this year’s Nobel Prize laureates have allowed us to understand how heat, cold and mechanical force can initiate the nerve impulses that allow us to perceive and adapt to the world around us. The TRP channels are central for our ability to perceive temperature. The Piezo2 chan...
David Julius and Ardem Patapoutian are awarded the Nobel Prize in Physiology or Medicine for their discoveries of receptors for temperature and touch. They used capsaicin, menthol, and pressure to identify novel ion channels that convert stimuli into electrical signals in the nervous system.
David Julius is a renowned neuroscientist who studies the molecular mechanisms of touch and pain. He discovered the TRP receptors that respond to temperature and chemical stimuli, and determined their structures using electron microscopy.

4 oct. 2021 · Julius, a UCSF professor and chair of physiology, is honored for his discoveries of receptors for temperature and touch. He uses natural products like capsaicin, menthol, and wasabi to study how TRP ion channels transmit pain signals to the brain.
David Julius is a US scientist who discovered the receptor for temperature and touch sensation. He used capsaicin, a compound from chili peppers, to identify the gene that encodes the heat-sensing receptor on neurons.
