Ardem Patapoutian (born 1967)^[1] is a Lebanese-American molecular biologist, neuroscientist, and Nobel Prize laureate of Armenian descent.^[2] He is known for his work in characterizing the PIEZO1, PIEZO2, and TRPM8 receptors that detect pressure, menthol, and temperature. Patapoutian is a neuroscience professor and Howard Hughes Medical Institute investigator at Scripps ResearchinLa Jolla, California. In 2021, he won the Nobel Prize in Physiology or Medicine jointly with David Julius.^[3]

Ardem Patapoutian (Armenian: Արտեմ Փաթափութեան) was born to a Lebanese Armenian family in Beirut, Lebanon.^[2][4][5] His father, Sarkis Patapoutian (better known by the pen name Sarkis Vahakn [hy]), is a poet and an accountant,^[6] while his mother, Haiguhi Adjemian, was the principal of an Armenian school in Beirut. He has a brother, Ara, and a sister, Houry.^[7] His grandparents settled in Lebanon from Hadjin after surviving the Armenian Genocide.^[8][9][10]

He is childhood friends with journalist and author Vicken Cheterian.^[11] He attended the Demirdjian and Hovagimian Armenian schools in Beirut.^[11] He enrolled at the American University of Beirut for a year before emigrating to the United States in 1986.^[5][12] He received a B.S. degree in cell and developmental biology from the University of California, Los Angeles in 1990 and a Ph.D. degree in biology from the California Institute of Technology in 1996 under direction of Barbara Wold.^[13][5][14]

As a postdoctoral fellow, Patapoutian worked with Louis F. Reichardt at the University of California, San Francisco.^[15] In 2000, he became an assistant professor at the Scripps Research Institute.^[16] Between 2000 and 2014, he had an additional research position for the Novartis Research Foundation.^[17] Since 2014, Patapoutian has been an investigator for the Howard Hughes Medical Institute (HHMI).^[14]

Patapoutian, a naturalized US citizen,^[5] lives in Del Mar, California with his wife Nancy Hong, a venture capitalist, and son, Luca.^{[18][19][20][21]}

Patapoutian's research is into the biological receptors for temperature and touch (nociception).^[3] The knowledge is used to develop treatments for a range of diseases, including chronic pain.^[22] The discoveries made it possible to understand how heat, cold and mechanical forces trigger nerve impulses.^[22]

Patapoutian researches the signal transduction of sensors. Patapoutian and co-workers inactivated genes.^[23] In this way, they identified the gene, that made the cells insensitive for touch.^[23] The channel for the sense of touch was called PIEZO1 (transl. pressure).^[23] Through its similarity to PIEZO1, a second gene was discovered and named PIEZO2.^[24] This ion channel, the more important of the two mechanoreceptors, is essential for the sense of touch.^[24][25] PIEZO1 and PIEZO2 channels have been shown to regulate additional important physiological processes including blood pressure, respiration and urinary bladder control.^[24]

Patapoutian also made significant contributions to the identification of novel ion channels and receptors that are activated by temperature, mechanical forces or increased cell volume.^[26][27] Patapoutian and co-workers were able to show that these ion channels play an outstanding role in the sensation of temperature, in the sensation of touch, in proprioception,^[28] in the sensation of pain and in the regulation of vascular tone. More recent work uses functional genomics techniques to identify and characterize mechanosensitive ion channels (mechanotransduction).^{[16][29][30][31]}

Patapoutian has an h-index of 68 according to Google Scholar,^[32] and of 63 according to Scopus^[33] (As of May 2020^[update]). He has been a Fellow of the American Association for the Advancement of Science since 2016, a member of the National Academy of Sciences since 2017^[34] and of the American Academy of Arts and Sciences since 2020.^[35]

In 2017, Patapoutian received the W. Alden Spencer Award,^[36] in 2019 the Rosenstiel Award,^[37] in 2020 the Kavli Prize for Neuroscience,^[38] and the BBVA Foundation Frontiers of Knowledge Award in Biology / Biomedicine.^[39]

In 2021, he was awarded the Nobel Prize in Physiology or Medicine jointly with David Julius for their discoveries of receptors for temperature and touch.^[3][40][41]

In October 2021 President of Lebanon Michel Aoun awarded Patapoutian the Lebanese Order of Merit.^[42]

In December 2021, Patapoutian received the American Academy of Achievement’s Golden Plate Award presented by Awards Council member Frances Arnold.^[43]

In 2022, Patapoutian was named by Carnegie Corporation of New York as an honoree of the Great Immigrants Award.^[44]

Patapoutian, the first Armenian Nobel laureate, received a hero's welcome when he visited Armenia in June 2022. Prime Minister Nikol Pashinyan awarded him the Order of St. Mesrop Mashtots,^[45] while the Armenian National Academy of Sciences elected him an honorary member,^[46] and the Yerevan State Medical University awarded him an honorary doctorate.^[47] Patapoutian gifted a replica of his Nobel medal to the History Museum of Armenia.^[48][49] HayPost issued a stamp dedicated to him.^[50]
