Rolf M. Zinkernagel

 
Scientist: Rolf Zinkernagel
 

Swiss immunologist (1944–)

Zinkernagel qualified as an MD at the University of Basle in 1970. He moved to the Australian National University, Canberra, where he gained his PhD in 1975. Zinkernagel returned to Switzerland in 1979 to work at the University of Zurich. In 1992 he was appointed head of the Department of Experimental Immunology.

While in Canberra, when still a graduate student, Zinkernagel worked with Peter Doherty on the role of T lymphocytes and major histocompatibility complexes in fighting infection. For their work in this field they shared the 1997 Nobel Prize for physiology or medicine.

(born Jan. 6, 1944, Basel, Switz.) Swiss immunologist and pathologist. He received his Ph.D. from the Australian National University. Studying T cells in mice infected with a meningitis virus, he and Peter Doherty found that those from one infected mouse would destroy infected cells from another only if the mice belonged to the same genetic strain: no immune response occurs unless the T cells recognize two signals, those of the virus and those identifying the cell as "self." In 1992 he became head of the University of Zürich's Institute of Experimental Immunology. In 1996 he and Doherty shared a Nobel Prize.

Rolf Martin Zinkernagel (January 6, 1944 in Riehen, Basel-Stadt, Switzerland) is Professor of Experimental Immunology at the University of Zurich.

Together with the Australian Peter C. Doherty he received the 1996 Nobel Prize in Physiology or Medicine for the discovery of how the immune system recognizes virus-infected cells. With this he became the 24th Swiss Nobel laureate.

Viruses infect host cells and reproduce inside them. Killer T-cells destroy those infected cells so that the viruses can't reproduce. Zinkernagel and Doherty discovered that, in order for killer T cells to recognize infected cells, they had to recognize two molecules on the surface of the cell -- not only the virus antigen, but also a molecule of the major histocompatibility complex (MHC). This recognition was done by a T-cell receptor on the surface of the T cell. The MHC was previously identified as being responsible for the rejection of incompatible tissues during transplantation. Zinkernagel and Dougherty discovered that the MHC was responsible for the body fighting meningitis viruses too.[1]

He received his MD from the University of Basel in 1970 and his PhD from the Australian National University in 1975. In addition to the Nobel Prize, he also won The Albert Lasker Medical Research Award in 1995, and the Cancer Research Institute William B. Coley Award in 1987.

He is a member of the Cancer Research Institute Scientific Advisory Council, The National Academy of Sciences, and The Academy of Cancer Immunology.
