Bruce A. Beutler

From Wikipedia, the free encyclopedia

Bruce A. Beutler, born in Chicago on 29 December 1957, is a US citizen. He is a Professor and Chairman of the Department of Genetics at The Scripps Research Institute, in La Jolla, California, USA. He is known for his molecular and genetic studies of inflammation and innate immunity, and in particular, for having purified tumor necrosis factor, demonstrating its important role in septic shock, and for discovering that the Toll-like receptors (TLRs) act as the principal sensors of infection in mammals. This latter discovery hinged on the positional cloning of the mammalian lipopolysaccharide (LPS) response locus, which identified the LPS receptor as TLR4. Beutler has been a leading advocate of forward genetic analysis of immunity, in which mutations that alter immune function are created through a random process, detected by their phenotypic effects, and then isolated by positional cloning.

Beutler received his B.A. from the University of California, San Diego in 1976 and his M.D. from the University of Chicago in 1981. From 1981 to 1983 he continued his medical training at the University of Texas Southwestern Medical Center at Dallas.

Between 1983 and 1985 he was Fellow at Rockefeller University of New York, where he became an Assistant Professor in 1985. He was also an Associate Physician at the Rockefeller University Hospital between 1984 and 1986.

He returned to Dallas in 1986 as an Assistant Professor in the Department of Internal Medicine of the University of Texas Southwestern Medical Center at Dallas, where he became an Associate Professor in 1990 and a Professor in 1996. In Dallas he was also an Assistant Investigator at the Howard Hughes Medical Institute from 1986, and became an Associate Investigator in 1991. Since 2000 he has been at The Scripps Research Institute.

Beutler received the prestigious Balzan Prize in 2007 together with Jules A. Hoffmann for his studies of innate immunity. Other notable honors have included the William B. Coley Award (in 2006, shared with Shizuo Akira), the Gran Prix Charles-Leopold-Mayer of the Académie des Sciences, France (in 2006), and the Robert Koch Prize (in 2004, shared with Jules A. Hoffmann and Shizuo Akira). He is an elected Member of the American Society for Clinical Investigation (1990), the Association of American Physicians (2001), and the United States National Academy of Sciences (2008).
