Helping Gen Z Do Science: Cultivating the Written Word - Minding The Campus I remember as a college freshman seeing a cartoon taped on the door of one of the physics labs in Cornelia Hall at Iona College. It showed a student complaining to his professor, saying, “I really understand the material, I just can’t do the problems.” It’s not rocket science to understand w...

Ardem Patapoutian, awarded the 2021 Nobel Prize in Physiology or Medicine, used pressure-sensitive cells to discover a novel class of sensors that respond to mechanical stimuli in the skin and internal organs.
Patapoutian and his collaborators first identified a cell line that gave off a measurable electric signal when individual cells were poked with a micropipette. It was assumed that the receptor activated by mechanical force is an ion channel and in a next step 72 candidate genes encoding possible receptors were identified. These genes were inactivated one by one to discover the gene responsible for mechanosensitivity in the studied cells. After an arduous search, Patapoutian and his co-workers succeeded in identifying a single gene whose silencing rendered the cells insensitive to poking with the micropipette. A new and entirely unknown mechanosensitive ion channel had been discovered and was given the name Piezo1, after the Greek word for pressure. Through its similarity to Piezo1, a second gene was discovered and named Piezo2. Sensory neurons were found to express high levels of Piezo2 and further studies firmly established that Piezo1 and Piezo2 are ion channels that are directly activated by the exertion of pressure on cell membranes (see figure).
The breakthrough by Patapoutian led to a series of papers from his and other groups, demonstrating that the Piezo2 ion channel is essential for the sense of touch. Moreover, Piezo2 was shown to play a key role in the critically important sensing of body position and motion, known as proprioception. In further work, Piezo1 and Piezo2 channels have been shown to regulate additional important physiological processes including blood pressure, respiration and urinary bladder control.
The 2021 Nobel Prize in Physiology or Medicine has been awarded jointly to David Julius and Ardem Patapoutian “for their discoveries of receptors for temperature and touch.”
