Immunology has a very long history at Washington University. From the time that the School of Medicine was founded in 1891, most basic and applied immunology has centered in three Departments: Pathology, Microbiology , and Medicine.
The first major figure in immunology was Leo Loeb, MD. Loeb was the second Chairman of Pathology from 1923 to 1938. With him starts the very close association of pathology with immunology at the medical school.
Loeb was one of the first investigators to study the relationship between self and non-self by using tissue transplantation. He postulated the presence of genetic factors that controlled whether grafts were tolerated or rejected. Loeb used both inbred guinea pigs and the first inbred strains of mice. He was one of the most important figures in histocompatibility research prior to the definition of the MHC locus by Peter Gorer, PhD in the late 1930s.
Microbiology and immunology
Immunology activities expanded greatly in the 1960s and 1970s. The Department of Microbiology hosted immunology until 1992. Two prominent Heads of Microbiology were Herman Eisen, MD and Joseph Davie, MD, PhD. Eisen made his seminal and now classical studies on the affinities of antibodies and on affinity maturation, examining the anti-hapten responses. Davie, who followed Eisen as Head of Microbiology, continued to examine the cellular response of B cells to haptens and made one of the first quantitative analysis of B cell responses.
Paul Lacy, MD, PhD became Head of Pathology in 1961 and developed the procedures for isolation of islets of Langerhans for use in transplantation as the treatment for diabetes. The basic principles of islet transplantation and the passenger leukocyte concept were developed by him in close association with Dr. Davie.
At about the same time, Donald Shreffler, PhD joined the faculty to become Head of Genetics. Shreffler, with Jan Klein, PhD, made the classic observations on the genetics of H-2, the MHC gene locus of the mouse. He also described the association of complement protein with the H-2 gene locus.
Rheumatology and immunology
In the 1960s and 1970s, immunology started to develop strongly in the Allergy and Rheumatology Divisions of the Department of Medicine. Charles Parker, MD headed the Allergy Division and made extensive studies on the allergic and anaphylactic responses. John Atkinson, MD discovered the complement regulatory proteins as a member and Chief of the Rheumatology Division.
In the late 1980s, with the arrival of Emil Unanue, MD as Head of the department, immunology research at Washington University began to move to the Departments of Pathology and Medicine. At this time, Microbiology began changing its emphasis to microbial pathogenesis. In recognition of this new emphasis, the Department of Pathology changed its name in 1996 to ‘Pathology and Immunology’.
Pathology and immunology
Today the Department of Pathology & Immunology is the department that centers and integrates all immunology activities of the school. In recognition of the high concentration of immunology research in the department, Skip Virgin, MD, PhD, who became chairman of the department in 2006, decided to create a new division called Immunobiology. As of January 2022, Kodi S. Ravichandran, PhD serves as the Chief of the Division of Immunobiology.
With the recognition that inflammation underpins a variety of diseases including Alzheimer’s, diabetes, metabolic syndrome and others, immunology research has permeated into many areas of research and is one of the top life science groups at the university.
Immunobiology activities at Washington University are represented by more than 50 laboratories within 8 different departments. The Department of Pathology & Immunology has the highest number of immunologists and serves to coordinate and center all the various activities, including the graduate program in Immunology offered through the Division of Biology and Biomedical Sciences.
Programs in immunology
The Department also coordinates all the teaching of immunology for both medical and graduate students. The other Departments with prominent immunology faculty include the Department of Medicine, particularly with the Division of Rheumatology; Pediatrics with its Immunology and Rheumatology Division; and Molecular Microbiology with an extensive program in pathogenesis that includes immunology.
