Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is an active component of chili peppers, which are plants belonging to the genus Capsicum. It is a chemical irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related alkaloids are called capsaicinoids and are produced as secondary metabolites by chili peppers, probably as deterrents against certain mammals and fungi. Pure capsaicin is a hydrophobic, colorless, highly pungent, crystalline to waxy solid compound.
Thermoception or thermoreception is the sensation and perception of temperature, or more accurately, temperature differences inferred from heat flux. It deals with a series of events and processes required for an organism to receive a temperature stimulus, convert it to a molecular signal, and recognize and characterize the signal in order to trigger an appropriate defense response.
Julius Axelrod was an American biochemist. He won a share of the Nobel Prize in Physiology or Medicine in 1970 along with Bernard Katz and Ulf von Euler. The Nobel Committee honored him for his work on the release and reuptake of catecholamine neurotransmitters, a class of chemicals in the brain that include epinephrine, norepinephrine, and, as was later discovered, dopamine. Axelrod also made major contributions to the understanding of the pineal gland and how it is regulated during the sleep-wake cycle.
Ragnar Arthur Granit was a Finnish-Swedish scientist who was awarded the Nobel Prize in Physiology or Medicine in 1967 along with Haldan Keffer Hartline and George Wald "for their discoveries concerning the primary physiological and chemical visual processes in the eye".
A neuroscientist is a scientist who has specialised knowledge in neuroscience, a branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.
Ulf Svante von Euler was a Swedish physiologist and pharmacologist. He shared the Nobel Prize in Physiology or Medicine in 1970 for his work on neurotransmitters.
James Edward Rothman is an American biochemist. He is the Fergus F. Wallace Professor of Biomedical Sciences at Yale University, the Chairman of the Department of Cell Biology at Yale School of Medicine, and the Director of the Nanobiology Institute at the Yale West Campus. Rothman also concurrently serves as adjunct professor of physiology and cellular biophysics at Columbia University and a research professor at the UCL Queen Square Institute of Neurology, University College London.
Rolf Martin Zinkernagel is Professor of Experimental Immunology at the University of Zurich. He was awarded the Nobel Prize in Physiology or Medicine in 1996 for the discovery of how the immune system recognizes virus-infected cells.
A Nobel Committee is a working body responsible for most of the work involved in selecting Nobel Prize laureates. There are five Nobel Committees, one for each Nobel Prize.
The transient receptor potential cation channel subfamily V member 1 (TrpV1), also known as the capsaicin receptor and the vanilloid receptor 1, is a protein that, in humans, is encoded by the TRPV1 gene. It was the first isolated member of the transient receptor potential vanilloid receptor proteins that in turn are a sub-family of the transient receptor potential protein group. This protein is a member of the TRPV group of transient receptor potential family of ion channels.
Sten Grillner is a Swedish neurophysiologist and distinguished professor at the Karolinska Institute's Nobel Institute for Neurophysiology in Stockholm where he is the director of that institute. He is considered one of the world’s foremost experts in the cellular bases of motor behaviour. His research is focused on understanding the cellular bases of motor behaviour; in particular, he has shown how neuronal circuits in the spine help control rhythmic movements, such as those needed for locomotion. He is current secretary general of International Brain Research Organization IBRO and President of the Federation of European Neuroscience Societies (FENS). For his work, in 2008 he was awarded the $1 million Kavli Prize for deciphering the basic mechanisms which govern the development and functioning of the networks of cells in the brain and spinal cord. This prize distinguish the recipient from the Nobel prizes in basic medical sciences.
The Nobel Prize in Chemistry is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895, awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. This award is administered by the Nobel Foundation, and awarded by the Royal Swedish Academy of Sciences on proposal of the Nobel Committee for Chemistry which consists of five members elected by the Academy. The award is presented in Stockholm at an annual ceremony on 10 December, the anniversary of Nobel's death.
Thomas Christian Südhof, ForMemRS, is a German-American biochemist known for his study of synaptic transmission. Currently, he is a professor in the School of Medicine in the Department of Molecular and Cellular Physiology, and by courtesy in Neurology, and in Psychiatry and Behavioral Sciences at Stanford University.
David Jay Julius is an American physiologist and Nobel Prize laureate known for his work on molecular mechanisms of pain sensation and heat, including the characterization of the TRPV1 and TRPM8 receptors that detect capsaicin, menthol, and temperature. He is a professor at the University of California, San Francisco.
John O'Keefe, is an American-British neuroscientist, psychologist and a professor at the Sainsbury Wellcome Centre for Neural Circuits and Behaviour and the Research Department of Cell and Developmental Biology at University College London. He discovered place cells in the hippocampus, and that they show a specific kind of temporal coding in the form of theta phase precession. He shared the Nobel Prize in Physiology or Medicine in 2014, together with May-Britt Moser and Edvard Moser; he has received several other awards. He has worked at University College London for his entire career, but also held a part-time chair at the Norwegian University of Science and Technology at the behest of his Norwegian collaborators, the Mosers.
The Perl-UNC Prize is awarded internationally in the field of neuroscience. Its purpose is two-fold: to recognize researchers for outstanding discoveries and seminal insights in neuroscience and to celebrate the strength of the neuroscience research program at the University of North Carolina at Chapel Hill.
Ardem Patapoutian is an Armenian-American molecular biologist, neuroscientist, and Nobel Prize laureate. 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 Research in La Jolla, California. In 2021, he won the Nobel Prize in Physiology or Medicine jointly with David Julius.
The 2022 Nobel Prize in Physiology or Medicine was awarded to the Swedish geneticist Svante Pääbo "for his research in the field of genomes of extinct hominins and human evolution". It was announced by Thomas Perlmann, secretary of the Nobel Assembly at Karolinska Institutet in Stockholm, Sweden, on 3 October 2022.
The 2020 Nobel Prize in Physiology or Medicine was awarded to the American virologists Harvey J. Alter, Michael Houghton and Charles M. Rice "for the discovery of Hepatitis C virus." During the award ceremony on December 10, 2020, Prof. Gunilla Karlsson-Hedestam said:
"The discovery of the Hepatitis C virus by this year’s Laureates laid the foundation for our current understanding about how the virus survives in its niche during the long chronic phase of the infection, and how liver disease develops. And importantly, it led to the development of highly effective anti-viral medicines that now cure the infection in almost all treated persons."
