Rolf M. Zinkernagel Biography

Rolf Martin Zinkernagel is a renowned Swiss immunologist who, along with Peter C. Doherty, was awarded the Nobel Prize in Physiology or Medicine in 1996 for their groundbreaking discoveries in cell mediated immune defense. With a passion for medicine, Zinkernagel initially aspired to work with leprosy patients in Africa but was denied the opportunity. He then explored surgery at a local hospital but soon realized it was not his calling. Determined to pursue his interests, he obtained his M.D from the University of Basel and embarked on post-doctoral work at the University of Lausanne. It was during this time that he developed a fascination with immunology and sought to delve deeper into research in this field. His chance came when he joined the Australian National University in Canberra, where he collaborated with Peter Doherty to uncover how T-cells identify and eliminate virus-infected host cells. Their groundbreaking work also shed light on the function of the major histocompatibility complex. Decades later, they were honored with the Nobel Prize for their remarkable contributions. Zinkernagel later dedicated his final years at the University of Zurich, focusing on immune protection and immune-pathology. Although he retired in 2008, he continues to contribute to biomedical research in Europe, particularly in Switzerland.

Childhood & Early Years

Rolf M. Zinkernagel was born on January 6, 1944 in Riehen, a village near Basel, Switzerland. His father was a PhD in biology and worked in a big pharmaceutical company in Basel and his mother was a laboratory technician. Rolf was born second of his parents’ three children. His elder brother, Peter, became an architect and his younger sister, Anne Marie, followed his mother’s footstep to become a lab technician.

Rolf began his education at a public school in Riehen. Later he went to Mathematisch-Naturwissenschaftliches Gymnasium in Basel. Since the school paid more importance to science and did not teach Latin as a compulsory subject, which was still considered essential for studying law or medicine, he took four years of voluntary Latin. In 1962, he received his matura (high school exit certificate). Since medicine offered a wider choice in profession, he took it up and enrolled at the University of Basel.

The next few years were quite tough. He first had to obtain his matura in Latin. In parallel with his medical studies, he also had to do his military service. He somehow managed all these and in 1968, passed National Board Examination, University of Basel, Faculty of Medicine.

Zinkernagel next decided to go to Africa to work among leprosy patients and study the disease. He applied to different international organizations including WHO, but was refused due to lack of experience. Therefore, on 1 January 1969, he joined the surgery department in a local hospital. Very soon he realized that surgery was not for him. Therefore, in the same year, he joined the Institute of Anatomy at the University of Basel and studied capillary growth in the epiphysis of the long bones, finally obtaining his M.D. in 1970. His thesis paper was on the clinical problems of neuritis of the plexus brachialis.

Career

In October 1970, after a short stint as a student of experimental medicine at the University of Zurich, Zinkernagel joined Department of Biochemistry at the University of Lausanne as a Post Doctoral Fellow. Here he worked on immunology and immune chemistry. Although the initial project was a failure he succeeded in obtaining some positive results on the role of Immunoglobulin-A acquired from hyper-immunized cows. This work also provoked him to look for a second postdoctoral position.

In 1973, he joined Department of Microbiology at John Curtin School of Medical Research under Australian National University (Canberra) with a Visiting Fellowship granted by Swiss Foundation. Here he found space in the laboratory of Peter Doherty and started working on immunology. Simultaneously, he started working for his doctoral degree and earned his PhD in early 1975. His dissertation paper was titled ‘The role of the H-2 gene complex in cell-mediated immunity to viral and bacterial infections in mice’. Concurrently, he also started collaborating with Peter Doherty on immune responses in mice against the lymphocytic choriomeningitis virus. Subsequently, they discovered how immune T-cells recognize virus-infected host cells and also detected the function of the major histocompatibility complex (MHC).

In 1976, Zinkernagel joined Scripps Clinical Research Institute at La Jola, California, U.S.A as an Associate Professor (Associate Member) in the Department of Immuno-pathology. Concurrently, he taught in the Department of Pathology at the University of California, San Diego. Sometime in 1979, he was made a full Professor (Member) at Scripps. Here he studied T cell maturation and development of the T cell repertoire, dependent on the transplantation antigen expression in the thymus.

In the fall of 1979, not long after becoming a full Member of Scripps, Zinkernagel moved back to Switzerland. Here he was appointed as an Associated Professor in the Department of Pathology at the University of Zurich. At Zurich, he had to organize everything from the scratch. Molecular biologist, Hans Hengartner, joined him at this stage and the two scientists formed collaboration that lasted until Zinkernagel retired in 2008.

In 1988, Zinkernagel was made a full professor. Later in 1992, he was appointed as the founding co-director of the university’s Institute of Experimental Biology. Here too, he continued his collaboration with Hans Hengartner, studying immune protection and immune-pathology caused by virus infections. Finally in the spring of 2008, he retired from both the positions.

Major Works

Zinkernagel is best remembered for his 1973 work with Peter Doherty on how the immune system tackles infection by the lymphocytic choriomeningitis virus, a meningitis-causing antigen. The research focused on the cytotoxic T lymphocytes or T cells; a white blood cell, capable of destroying the invading viruses and virus-infected cells. They found that T cells from an infected mouse would destroy virus-infected cells from another mouse only if it belongs to genetically identical strain. Contrarily, if it belongs to a different genetic strain, the T cell would simply ignore it. They also established that in order to kill infected cells, along with foreign molecules, T cells need to recognize a self-molecule called major histocompatibility complex (MHC). It is the MHC, which tells the immune system that a particular cell belongs to one’s own body. This discovery threw new light on the general mechanism of cell immunity. It also provided the foundation for development of vaccines and medicines for infectious diseases, inflammatory diseases and cancer.

Awards & Achievements

In 1996, Zinkernagel and Peter Doherty were jointly awarded the Nobel Prize in Physiology or Medicine “for their discoveries concerning the specificity of the cell mediated immune defence”.

Personal Life & Legacy

Zinkernagel met his future wife Kathrin Lüdin while they were studying medicine at the University of Basel as classmates. They got married in November 1968, two weeks after they had sat for their final board examination. She is now a practicing physician. The couple has three children. Among them, their eldest daughter, Christine Zinkernagel, is an immunologist. Their second daughter, Annelies Zinkernagel and son, Martin Zinkernagel, are physicians.
