# Bruce Beutler

> Bruce Beutler is an American immunologist and geneticist, Director of the Center for the Genetics of Host Defense at the University of Texas Southwestern Medical Center in Dallas. He shared the 2011 Nobel Prize in Physiology or Medicine with Jules Hoffmann and Ralph Steinman for discoveries concerning the activation of innate immunity. Beutler's pivotal contribution was discovering that the Toll-like receptor 4 (TLR4) is the sensor for bacterial lipopolysaccharide (LPS), the molecule responsible for septic shock. Using a forward genetic screen in mice, he identified a single point mutation in the Tlr4 gene that conferred resistance to LPS-induced endotoxic shock, proving that TLR4 is the long-sought receptor for LPS. This discovery illuminated the molecular basis of how the innate immune system detects bacterial infection and triggers inflammatory responses. The Toll-like receptor family, which Beutler's work helped establish as central to innate immunity, has since been found to recognize a vast range of pathogen-associated molecular patterns, making them critical targets for vaccine adjuvants, cancer immunotherapy, and treatments for inflammatory and autoimmune diseases. Beutler developed the ENU forward genetics platform at UTSW, a systematic approach to identifying immune genes through mutagenesis screens, which has uncovered hundreds of genes involved in host defense. He has received the Shaw Prize in Life Science and Medicine, the Balzan Prize, and the William Coley Award. He is a member of the National Academy of Sciences.
