description Rolf Zinkernagel Overview
Rolf Zinkernagel is a Swiss immunologist whose collaborative work with Peter Doherty revealed how the immune system's T cells specifically recognize and destroy infected cells. They discovered that T cells must simultaneously recognize both the viral antigen and the host's own Major Histocompatibility Complex (MHC) molecules, a phenomenon known as MHC restriction. This finding explained the cellular basis of self-tolerance and immune defense against intracellular pathogens. For their transformative discovery, Zinkernagel and Doherty shared the 1996 Nobel Prize in Physiology or Medicine.
help Rolf Zinkernagel FAQ
What major immunology discovery did Rolf Zinkernagel make?
Rolf Zinkernagel, working alongside Peter Doherty in the 1970s, discovered how the immune system's T cells recognize and destroy virus-infected cells. They found that T cells must simultaneously recognize both the viral antigen and the host's own Major Histocompatibility Complex (MHC) molecules, a concept known as MHC restriction.
Did Rolf Zinkernagel win a Nobel Prize for his T cell research?
Yes, Rolf Zinkernagel and Peter Doherty were jointly awarded the 1996 Nobel Prize in Physiology or Medicine. Their groundbreaking research fundamentally changed the understanding of how the cellular immune system distinguishes between healthy cells and infected cells.
What animal model did Zinkernagel and Doherty use for their famous experiment?
The duo conducted their pivotal experiments using mice infected with the Lymphocytic Choriomeningitis Virus (LCMV). By studying the immune response in these mice, they observed that T cells from one strain of mice would not react to infected cells from a different strain due to differences in their MHC molecules.
Where did Rolf Zinkernagel conduct his Nobel Prize-winning research?
Zinkernagel and Doherty performed their pivotal research at the John Curtin School of Medical Research at the Australian National University in Canberra. Zinkernagel later returned to Switzerland to continue his work at the University of Zurich.
