David Julius and Ardem Patapoutian win 2021 Nobel Prize in Medicine

The molecular biologists have won the 2021 Nobel Prize in Physiology or Medicine for their discoveries of receptors for temperature and touch, the Nobel Committee has announced in Stockholm.




The Nobel Prize for Medicine starts a week of prizes

David Julius and Ardem Patapoutian have been awarded this year's Nobel Prize in Physiology or Medicine.

The Nobel Committee's Thomas Perlmann said Julius and Patapoutian had "unlocked one of the secrets of nature," and that is how we sense and feel our way around in the world. Our sense of touch, how we sense depth, reach out for things, and also how we experience pain.

In a year when many may have expected the prize to go to at least one of the makers of a COVID-19 vaccine, Perlmann said this was deemed the most important discovery in Physiology or Medicine in 2021. He said he couldn't say more without "breaking confidentiality." 

This is basic research, which the committee says will have benefits for future drug development.  

As for the developments in coronavirus research over the past year and a half, the committee would only say that it worked on the basis of discoveries that had been nominated. 

They wouldn't say whether drug and vaccine discoveries against SARS-CoV-2 had been nominated.  


Julius and Patapoutian's work will be used in future drug developments

Red hot chili receptors 

We move about in the world as though it were second nature — and, indeed, it is.  

But until this novel research into proprioception, the Nobel Committee says we had yet to work out how temperature and mechanical stimuli get converted into electrical impulses in the human nervous system.  

That is how we sense and perceive temperature, and even pain, and why those senses and perceptions are different for many people.  

Some of us feel the cold more than others. Some of us can walk over burning coals, and others simply can't stand the heat.   

And it's the way that the nervous system interprets those electrical impulses that determines how we react and feel. 

Perhaps that's why David Julius landed on capsaicin as a basis for his research. 

Capsaicin is a chemical found in chili peppers. It's what makes chilis burn the nerve endings on our tongues or our eyes if we touch them after cutting up a chili. 

Julius used that chemical irritant and the burning sensation it creates "to identify a sensor in the nerve endings of the skin that responds to heat."  

His work led to the discovery of TRPV1, an ion channel that is activated by painful heat. Ion channels are proteins that allow ions, such as sodium, potassium, calcium, to pass through the cell membrane. They are vital for the nervous system, the contraction of the heart and skeletal muscle and other physiological functions. 

And this particular one allows us to understand pain just a little bit better.  

And novel receptors 

Ardem Patapoutian, meanwhile, used "pressure-sensitive cells to discover a novel class of sensors that respond to mechanical stimuli in the skin and internal organs," the committee writes. 

What did Patapoutian's team do? They poked a cell with a small pipette (a micropipette) and watched how 72 individual genes within the cell reacted.  

They found two genes within the cell that were insensitive to their being poked. But it was more than that: Those genes, it seems, could switch their sensitivity off.  

The two genes were names Piezo1 and 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" when pressure is exerted on cell membranes. 

Their work together 

It's now said that TRP and Piezo channels influence a range of physiological functions that depend on how we sense temperature or "mechanical stimuli" — that could be the prick of a vaccine needle — and how we adapt to those sensations. 

Placed together, the discoveries have been influential for our understanding about core body temperature, inflammatory pain, protective reflexes, respiration, blood pressure, and urination. 

"This knowledge," says the Nobel Committee, "is being used to develop treatments for a wide range of disease conditions, including chronic pain."     

Who are the winners? 

David Julius is a biochemist and professor of physiology at the University of California, San Francisco. In 2020, Julius was awarded the Kavli Prize in Neuroscience for this same body of research. It was cited as having created new approaches for the development of safe and targeted painkillers that may have lower addictive properties than opioids. 

Ardem Patapoutian, a professor of neuroscience at Scripps Research, an institute in California in the US, shared that 2020 Kavli Prize with Julius. It wasn't the first time: In 2019, they shared the Rosenstiel Award for Distinguished Work in Basic Medical Research. And now they share a Nobel Prize.  

Prize-heavy week

Medicine is always the first in a week of Nobel Prizes. Tuesday is traditionally the day for the Physics prize and Wednesday it's Chemistry. 

Later in the week, there will be Nobel Prizes for Literature and Peace, and then Economic Sciences.

Pomp and ceremony in December

In 2020, the Medicine prize was won by Harvey J. Alter, Michael Houghton und Charles M. Rice for the discovery of the Hepatitis C virus.

The Nobel Prize for Physiology or Medicine has been awarded 111 since the prize's first year in 1901. It's gone to 222 scientists, including two married couples, but only 12 women. 

This year's winners receive cash prize of 10 million Swedish Krona (about €980,000), a Nobel Medal and a range of other trinkets.

But they will have to wait until December 10, because tradition also has it that the prizes is handed out at a gala dinner in Stockholm.

Two Americans win Medicine Nobel for work on heat and touch
  • Summary
  • Americans Julius and Patapoutian win Nobel medicine prize
  • Discoveries of receptors for temperature, touch recognised
  • Discoveries could pave the way for new pain-killers

STOCKHOLM, Oct 4 (Reuters) - American scientists David Julius and Ardem Patapoutian won the 2021 Nobel Prize for Medicine on Monday for the discovery of receptors in the skin that sense temperature and touch and could pave the way for new pain-killers.

Their work, carried out independently, has helped show how humans convert the physical impact from heat or touch into nerve impulses that allow us to "perceive and adapt to the world around us," the Nobel Assembly at Sweden's Karolinska Institute said.

"This knowledge is being used to develop treatments for a wide range of disease conditions, including chronic pain."

Patapoutian, who was born in 1967 to Armenian parents in Lebanon and moved to Los Angeles in his youth, learnt of the news from his father as he had been out of contact by phone.


"In science many times it is the things we take for granted that are of high interest," he said of winning the more than century-old prize, which is worth 10 million Swedish crowns ($1.15 million).

He is credited for finding the celular mechanism and the underlying gene that translates a mechanical force on our skin into an electric nerve signal.

"(For) us being in the field of sense, touch and pain, this was the big elephant in room where we knew they existed, we knew they did something very different," he said.

Patapoutian is a professor at Scripps Research, La Jolla, California, having previously done research at the University of California, San Francisco, and California Institute of Technology, Pasadena.


New York-born Julius, 65, is a Professor at University of California, San Francisco (UCFS), after earlier work at Columbia University, in New York.

His findings were inspired by his fascination for how natural products can be used to probe biological function and he used capsaicin, the molecule that makes chili peppers spicy by simulating a false sensation of heat, to understand the skin's sense of temperature.

Julius hopes his work will help identify new strategies for treating chronic pain syndromes.

"We all know there's a real lack of drugs and approaches to treat chronic pain," Julius said in a 2017 video posted on Youtube by UCSF. "I think we need some new insights and new ideas for treating pain, pharmacologically and other ways, and I think our work will contribute to that."


Jan Adams, chief science officer at German drugmaker Gruenenthal GmbH, which markets pain relief skin patches and creams based on the TRPV1 capsaicin receptor discovered by Julius, said his work had "opened up a whole new field of research for new non-opioid pain therapies".


Both laureates were caught off guard, according to the committee. Professor Thomas Perlmann, Secretary-General for the Nobel Assembly and the Nobel Committee for Physiology or Medicine, described them as "incredibly happy and as far as I could tell very surprised and a little bit shocked."

The prestigious Nobel prizes, for achievements in science, literature and peace, were created and funded in the will of Swedish dynamite inventor and businessman Alfred Nobel. They have been awarded since 1901, with the economics prize first handed out in 1969.


The Nobel Prize for Physiology or Medicine, shared in equal parts this year by the two laureates, often lives in the shadow of the Nobels for literature and peace, and their sometimes more widely known recipients.

But medicine has been thrust into the spotlight by the COVID-19 pandemic, and some scientists had suggested those who developed coronavirus vaccines could be rewarded this year or in coming years.

The pandemic continues to haunt the Nobel ceremonies, which are usually full of old-world pomp and glamour. The banquet in Stockholm has been postponed for a second successive year amid lingering worries about the virus and international travel. read more

‘My family’s history is represented here’ - Ardem Patapoutian visits Armenian Genocide Memorial


1086159.jpg 14:55, 16 June 2022

YEREVAN, JUNE 16, ARMENPRESS. Armenian-American scientist, Nobel Prize laureate and molecular biologist Ardem Patapoutian visited today the Armenian Genocide Memorial in Yerevan, the Genocide Museum-Institute said.

The guests were greeted by Edita Gzoyan, Deputy Director for Scientific Affairs at the Armenian Genocide Museum-Institute, who introduced the history of the creation of the Memorial. She also presented the history of the three cross-stones stationed in the territory of the Memorial, which are dedicated to the memory of Armenians killed during ethnic cleansing conducted against the Armenian population in the territory of Azerbaijan in the end of the past century.



Ardem Patapoutian laid a wreath at the Memorial, then the guests laid flowers at the Eternal Flame, by honoring the memory of the victims with a moment of silence.


The guests got acquainted with the permanent and temporary exhibitions in the Museum, and in the end Ardem Patapoutian left a note in the Honorary Guest Book: “My history and my family’s history is all represented here. My family is the victim of the atrocities that led my grandparents to Lebanon, and then my journey to US”, he said.

Edita Gzoyan thanked Mr. Patapoutian for the visit and handed over the recently published book titled “Aleppo Salvation House: 1 464 Testimonies of Armenian Genocide Survivors” to him.

In the end of the visit, Ardem Patapoutian planted a silver fir tree in Memory Park.

Armenian PM receives Nobel laureate Ardem Patapoutian

1086165.jpg 15:35, 16 June 2022

YEREVAN, JUNE 16, ARMENPRESS. Prime Minister of Armenia Nikol Pashinyan hosted today Armenian-American scientist, Nobel Prize laureate and molecular biologist Ardem Patapoutian, who arrived in Armenia on the sidelines of Science and Business Days 2022 forum organized by the Ministry of Economy, the PM’s Office said.

“Dear Mr. Patapoutian, I am glad to welcome you and to getting acquainted with you. I welcome your visit to Armenia.


Yesterday I carefully listened to your speech during the graduation ceremony in the Yerevan State University and I am very impressed. I think that Armenia and the entire Armenian people consider your achievements as their own. Of course, it’s a great occasion of pride for us that finally we have also our compatriot among the Nobel laureates.

I also want to thank you for your readiness to support the development of science and education in Armenia. Making tangible reforms in this area is one of our key strategic directions, and we think that science, education reforms are of strategic significance and should determine our country’s future. Of course, it’s important for us to engage the potential of our compatriots in this process, if there is such a readiness.

I want to once again welcome you and I would like to hear from you about your visit, how is it going and how do you spend your time in Armenia”.

In his turn, Ardem Patapoutian said:

“It’s a great honor for me to meet with you and be here. I had a wonderful visit, I am impressed by the welcome you and the government showed to me, but most importantly, by the welcome of the nation.

The happiness of the students I met is really shocking, and I think that even the United States does not appreciate its young scientists in this way. I will be very happy to help in any way, within my capacities. I already met many ministers, education and science sector representatives and the people who have established high-tech companies.

I share your view that science and technologies are very important for the next stage of the life of Armenia, not for the economy, the military field only, but for all areas.

I visited Synopsis, TUMO, and these are two wonderful examples of Armenian ingenuity, which are useful not only for the industry but also contribute to education, improve education which will later nourish and help the economy. I hope I can be useful in the field of healthcare and informatics that has a mathematical basis. I think it will have a major place in future biology.

With its limited budget Armenia could show a strategic approach to those areas where there is an opportunity to reach the maximum in a short period of time. I think there are some directions where we can compete, there are also directions where, I think, it is meaningless to become the best one. I repeat that I will be glad to help within my capacities. I am very excited for the general anti-corruption movement that you have started which is already reflected in the academic field”.

Thereafter, Nikol Pashinyan and Ardem Patapoutian discussed the problems in the fields of science and education in Armenia and the government’s ongoing reforms.

PM Pashinyan said the government is planning to increase the funding for science by 2026 and added that it has already been raised by 80%. He attached importance to Mr. Patapoutian’s observations, recommendations and proposals for promoting the reforms. Pashinyan said that Patapoutian’s example is encouraging for the youth, expressing confidence that his visit will inspire them.

The Armenian-American scientist said he is ready to contribute to the development of science and education in Armenia with his knowledge, experience and potential.

At the end of the meeting, Pashinyan awarded Patapoutian with the Order of St. Mesrop Mashtots for his significant achievements in the field of biology.

Armenia issues postage stamp honoring San Diego Nobel Prize winner
Ardem Patapoutian, an Armenian American, is on the staff at La Jolla’s Scripps Research
JUNE 15, 2022 9 AM PTpngOjzjPpTtrx.png

Armenia on Tuesday issued a postage stamp that honors San Diego’s Ardem Patapoutian, the Armenian American biologist who shared the 2021 Nobel Prize in physiology or medicine for helping discover cell receptors that enable people to sense heat, cold, pain, touch and sound.

Patapoutian traveled to Yerevan, the capitol of Armenia, for a ceremony showcasing the stamp, which features a drawing of the scientist’s face, with his Nobel Prize in the background. He is the first Armenian to win a Nobel.

He later took to Twitter to say, “Thank you #Armenia for shining a limelight on #science and honoring scientists. Yes! This is an actual stamp with my face on it, tweeps! I am trying to figure out how to process all this...”

Patapoutian later told the Union-Tribune by email: “It is pretty surreal! If anyone told 18-year-old me that my face would be on a stamp I would have felt mocked. This is very special to come from Armenia; as a kid I used to collect Armenian stamps!”

Armenian officials said the the stamp was printed by the French printing house Cartor, and that 20,000 of the stamps are expected to go into circulation.

‘The welcome I received shows science is valued in Armenia’ - Ardem Patapoutian

1086174.jpg 16:47, 16 June 2022

YEREVAN, JUNE 16, ARMENPRESS. The Presidency of the National Academy of Sciences of Armenia held a session today hosting Armenian-American scientist, Nobel Prize laureate and molecular biologist Ardem Patapoutian.

During the meeting a diploma of an honorary member of the National Academy of Sciences of Armenia was handed over to Ardem Patapoutian.


NAS President Ashot Saghyan congratulated Mr. Patapoutian for the great achievement, calling it also one of the achievements of the Armenian people. “We have agreed with Mr. Patapoutian. Next time he will visit Armenia at the invitation of the Academy. There will be meetings, reports”, he said.

In his turn the Armenian-American scientist said that the welcome he received in Armenia shows that science and scientific achievements are valued in Armenia. “I started my work in a laboratory, but I never imagined that science could be a profession. But then I fell in love with that work. Surprisingly, the Nobel Prize was the motivation for me that I am proud of my biography and institutions where I studied. I have been engaged in science with pleasure and dedication”, he said.

Ardem Patapoutian was elected honorary member of the National Academy of Sciences of Armenia by the June 9 decision of the NAS general assembly.
