Richard Axel

From Wikipedia, the free encyclopedia

Richard Axel (born July 2, 1946, New York City) is an American neuroscientist whose work on the olfactory system won him and Linda B. Buck, a former post-doctoral scientist in his research group, the Nobel Prize in Physiology or Medicine in 2004.

In their landmark paper published in 1991, Buck and Axel cloned olfactory receptors, showing that they belong to the family of G protein coupled receptors. By analyzing rat DNA, they estimated that there were approximately one thousand different genes for olfactory receptors in the mammalian genome. This research opened the door to the genetic and molecular analysis of the mechanisms of olfaction. In their later work, Buck and Axel have shown that each olfactory receptor neuron remarkably only expresses one kind of olfactory receptor protein and that the input from all neurons expressing the same receptor is collected by a single dedicated glomerulus of the olfactory bulb.

[edit] Biography

Born in New York City, New York, Axel graduated from Stuyvesant High School in 1963,[1] received his A.B. in 1967 from Columbia University, and his M.D. in 1971 from Johns Hopkins University. He returned to Columbia later that year and became a full professor in 1978.

Richard Axel is known to be a great aficionado of opera and was referred to as an 'opera addict' by the Nobel prize winner Eric Kandel. Axel attended Joan Sutherland's debut performance at New York's Metropolitan Opera with his high school friend Jerold Brenowitz, who later became a heart surgeon.

During the late 1970s, Axel, along with microbiologist Saul J. Silverstein, and geneticist Michael H. Wigler, discovered a technique of cotransformation, a process which allows foreign DNA to be inserted into a host cell to produce certain proteins. Patents, now colloquially referred to as the "Axel patents", covering this technique were filed for February 1980 and were issued in August 1983. As a fundamental process in recombinant DNA research as performed at pharmaceutical and biotech companies, this patent proved quite lucrative for Columbia University, earning it almost $100 million a year at one time, and a top spot on the list of top universities by licensing revenue. The Axel patents expired in August 2000.

Axel's primary research interest is on how the brain interprets the sense of smell, specifically mapping the parts of the brain that are sensitive to specific olfactory receptors. He holds the titles of University Professor at Columbia University, Professor of Biochemistry and Molecular Biophysics and of Pathology at Columbia University's College of Physicians and Surgeons, and Investigator of the Howard Hughes Medical Institute. He also taught for Duke University's Program in Genetics and Genomics.[2]

Axel is married to fellow scientist and olfaction pioneer Cornelia "Cori" Bargmann.

Axel's ex wife is Ann Axel. Ann Axel, M.S.W., was born in 1947 to Norman and Winifred Cotrell. Ann Axel attended Barnard College, and later the Hunter School of Social Work. She specializes in psychiatry, and is a celebrated social worker at Columbia Eastside, affiliated with Columbia University Medical Center in Manhattan.

[edit] Key Papers

This is the paper in which Linda Buck & Richard Axel first describe the discovery of the odorant receptors, which was the basis for their shared Nobel Prize.

These are the papers describing DNA transfection, a critical tool for the entire revolution in biology, in which genes can be modified and then stably transferred into cells. This paper was the basis for the "Axel patent" which at one time brought Columbia University as much as $100 million per year.
