Doherty, Peter Charles

Peter Charles Doherty, 1940–, Australian immunologist, Ph.D., Univ. of Edinburgh, 1970. He was a research fellow at Australian National Univ. (1972–75), a professor at the Wistar Institute, Philadelphia (1975–82), and a professor at the Australian National Univ. (1982–88). In 1988 Doherty became chairman of the Dept. of Immunology at St. Jude Children's Research Hospital in Memphis, Tenn. In the early 1970s, he and Rolf Zinkernagel discovered that for white blood cells (lymphocytes) to fight infection the cells have to recognize not only the "foreign" molecules of the virus but also certain "self" molecules known as histocompatibility antigens. Their work has had implications in medicine for the development of therapies to boost immune response against threats such as harmful microorganisms and cancer as well as in treatment of autoimmune disorders such as diabetes and multiple sclerosis. In 1996 Doherty and Zinkernagel received the Nobel Prize in physiology or medicine for elucidating how the immune system recognizes virus-infected cells.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
