On October 4, CNN reported that the Nobel Prize in this year is awarded to 2 American scientists with research on how people feel the temperature and contact (tactile) How.0 / 2: 38 namtheo, the Nobel Biological and Medicine Prize in 2021 was given to David Julius and Ardem PatapouTian because of their discoveries about the felt receptors for temperatures and touch scientists. Received the award because the mechanical description of how people felt hot and cold temperatures and pressure through nervous pulses.Julius is a professor at the University of California, San Francisco. PatapouTian is a professor at Howard Hughes Institute of Health in La Jolla, California (USA)
. "Our ability to feel the heat, coldness and tactile is essential for existence and foundation for interaction Our with the world around "- The Nobel Council said in a statement announcing awards.Julius used Capsaicin, a spicy spicy compound extracted from chili causing hot feeling, to identify a feeling Turning in the nerve heads of the skin react to heat .
. and PatapouTian has used pressure sensitive cells to discover a new type of response sensor.Hai scientist is awarded Nobel Y prize Born this year - Photo: The Nobelthomas Perlmann awards committee, Nobel Council secretary and the Nobel committee, said this discovery "opened the secrets of nature ... it explained at the molecular level These stimuli are converted into a neurological signal. It is an important and profound discovery ". Nobel Board explains that when Julius starts studying why Capsaicin caused a burning feeling, it was known that this compound activates painful nerve cells - but that happens exactly how a "unannounced puzzle" .julius and the group His created a library of millions of DNA paragraphs corresponding to the genes manifested in feeling nerve cells that could react with pain, heat and tactile (contact, collision). After that, they plugged genes from this collection into cells that often did not respond to capsaicin to find the only gene that caused sensitivity
Julius then realized that the capsaicin receptor he discovered was a receptor Heat inductive enabled at temperature is considered to be painful, the Nobel Commission said. Intellectual, PatapouTian and his colleagues are trying to understand how mechanical stimulus can be converted into the reactions of collision senses (touch) and our pressure. The research group has identified 72 candidate genes that can encode receptors and "turn them off" each gene One to detect genes causing mechanical sensitivity.Abdel El Manira, the Nobel Assistant member of the Biomedical Biology said that this discovery was made more than a decade ago. "This is the right time (Leaving it) to be recognized. It has changed our point deeply about how we feel the world "- Manira stressed. . Dịch vụ:
