Two Americans Win Nobel Prize in Medicine for Discovering Heat and Tactile Receptors


The 2021 Nobel Prize in Physiology and Medicine was awarded to two US-based scientists for the discovery of receptors for temperature and contact, the awarding agency announced on Monday.

The findings of California-based scientists David Julius and Aldem Patapoutian have focused on the area of ​​somatosensory, more commonly known as tactile or bodily sensory abilities. rice field.

“A breakthrough discovery has helped us understand how heat, cold, and mechanical forces initiate neural impulses to recognize and adapt to the world around us.” NSAssembly described in statement It announced the winner.

The duo’s profound discoveries may have paved the way for new ways to treat pain and even heart disease.

“This knowledge is being used to develop treatments for a wide range of medical conditions, including chronic pain.” NSssembly said.

Julius, who works at the University of California, San Francisco, has identified a neural sensor that allows the skin to respond to heat using capsaicin, the active ingredient in chili peppers, the committee explained.

Patapoutian, who works at Lahoya’s laboratory, has discovered a new class of sensors using pressure-sensitive sensor cells that respond to mechanical stimuli in the skin and internal organs.

The findings rapidly increase scientists’ understanding of how our nervous system perceives heat, cold, and mechanical stimuli, between our senses and the environment around us. We have identified important links that lacked the perception of complex interactions in.

“That is, pain is very closely related to temperature and tactile sensation, and we know that these systems are certainly involved in pain transmission,” said the Nobel Committee office. Said the director, Thomas Pearlman. “Also, in certain places and in some companies, there is activity to develop new drugs that may be involved in pain, chronic pain, etc.”

Last year, U.S.-based scientists Harvey J. Alter and Charles M. Rice, along with British-born scientist Michael Houghton, are a major cause of liver disease affecting millions of people around the world. Received the Nobel Prize in Medicine for the discovery of hepatitis C virus. ..

The prestigious Nobel Prize includes a gold medal and prize of SEK 10 million (over $ 1.14 million). This money comes from a bequest left by Swedish inventor Alfred Nobel, the creator of the award, which died in 1895.

This award will be presented for the first time this year. Other awards are for outstanding achievements in the fields of physics, chemistry, literature, peace and economics.
