Paul C. Montgomery, Ph.D., is professor of Immunology and Microbiology. He came to the School of Medicine in 1983 from the University of Pennsylvania where he was Professor of Microbiology and Chairman of the Immunology Graduate Group. Dr. Montgomery received his Ph.D. from the University of Pennsylvania in 1969 and was a postdoctoral fellow at the National Institute for Medical Research, London. He is the former recipient of a Fogarty Senior International Fellowship and was a visiting professor in the Department of Experimental Medicine at the University of Louvain in Brussels.
Dr. Montgomery's current research interests include: immunochemical and cellular aspects of immunity at mucosal surfaces; molecular properties of secretory IgA; mechanisms controlling IgA antibody responses; and the immunobiology of the eye. His laboratory has documented that the lacrimal compartment of the eye is linked to the common mucosal immune system by the selective migration of IgA-bearing lymphocyte populations. This linkage has significance in the development of appropriate delivery schemes for potential vaccine agents useful in preventing ocular disease. Ongoing work is directed at answering the following questions:
1. Can cytokines be employed to effectively regulate secretory IgA antibody responses?
2. What is the regulatory role of anti-idiotypic antibodies in mucosal responses?
3. How does intranasal antigen administration stimulate IgA antibody induction in tears and saliva?
4. What role do lymphocyte subsets and cell traffic mechanisms play in mucosal-associated immune responses?
5. What are the mechanistic events and molecular interactions governing lymphocyte localization in mucosal tissues?
6. Do mucosal-associated responses play a role in protection and/or pathogenesis following exposure to infectious agents?
7. What is the role of the dendritic cell in mucosal immune responses?
These investigations, in the rat model, utilize biochemical, immunological and molecular approaches together with cell and tissue culture systems, adherence and motility assays as well as flow cytometry. It is expected that these studies will provide new strategies applicable to the design of clinically relevant mucosal immunization strategies to protect mucosal surfaces.
