About Philippa Marrack
Philippa Marrack was born in Ewell, England, on June 28, 1945. Her father was in the Royal Navy, so her family moved around a lot. The longest she lived in one place when she was young was in Cambridge. This is where she started her university studies.
After finishing her studies in England, she moved to the United States. There, she met her husband and research partner, John W. Kappler. They have worked together on many scientific projects. They have also made big advancements in understanding the immune system. Outside of her science work, Philippa Marrack enjoys playing the piano. She also likes running with her Labrador dogs along the Platte River.
Her Early Studies
Philippa Marrack went to Cambridge University. She earned her first degree in 1967 and her Ph.D. in 1970. For her Ph.D., she worked at the MRC Laboratory of Molecular Biology. She studied the differences between T cells and B cells. These are two important types of immune cells. Her advisor, Alan Munro, was interested in working with her because of her family. Philippa's great-uncle, John Marrack, was a well-known immunologist in the 1930s. She says he helped inspire her to study immunology.
After her Ph.D., Dr. Marrack moved to California. She did more research at the University of California, San Diego. She learned a lot from her mentor, Richard Dutton. He taught her how to write scientific papers, give lectures, and manage a lab. He also taught her how to think deeply about science.
Her Scientific Career
Dr. Marrack's first teaching job was at the University of Rochester. There, she taught immunology to college students. She and John Kappler started a research lab together. She also received money from groups like the American Heart Association to study T cells.
Later, she became a professor at National Jewish Health and the University of Colorado Denver. She has written over 300 scientific articles. Her work has been cited by many other scientists. This shows how important her research is. She is known as one of the most influential researchers in the country.
Discoveries in Immunology
In 1983, Philippa Marrack and John Kappler made a huge discovery. They found and isolated the T cell receptor. Think of the T cell receptor as a special "sensor" on the surface of T cells. This sensor helps T cells recognize invaders like viruses or bacteria.
In 1987, Dr. Marrack discovered how the immune system can tell the difference between our own body's cells and harmful invaders. Our body gets rid of T cells that might attack our own tissues. This happens in a special organ called the thymus. This process stops our immune system from harming us. If these "bad" cells are not destroyed, they can cause autoimmune diseases. These are diseases where the immune system mistakenly attacks the body. Examples include diabetes, Multiple sclerosis, and lupus.
Later, in 1990, Marrack and Kappler discovered superantigens. These are powerful toxins that can make many T cells react at once. This can cause a very strong immune response. It can lead to serious symptoms, like those seen in toxic shock syndrome or food poisoning.
Dr. Marrack's current research looks at why some autoimmune diseases are more common in women. She and Kappler recently found a group of B cells that might help explain this. Her work has greatly improved our understanding of vaccines, HIV, and immune disorders.
Professional Activities
Dr. Marrack has been part of many important scientific groups. She has served on the editorial boards for major science journals like Cell and Science. She has also been on boards for the American Cancer Society and the National Institutes of Health.
From 1986 to 2017, she was an investigator for the Howard Hughes Medical Institute. She also served as president of the American Association of Immunologists (AAI) from 2000 to 2001. She became a member of the National Academy of Sciences in 1989. In 1997, she became a Fellow of the Royal Society in Great Britain.
