Research & Publications
A general interest of the lab is the role that infection plays in setting the stage for chronic immune mediated inflammatory diseases. Recently we have begun to investigate the human host immune response to infection with Borrelia burgdorferi the causative agent of Lyme disease. To date there is little information available as to how various cellular immune elements are mobilized following B. burgdorferi infection. We hypothesize that the varying outcomes (cure vs. long term symptoms) that follow infection with B. burgdorferi are the result of differences in the host immune response to the infection. We are addressing this issue by following a cohort of patients from onset of presentation with symptoms of infection through the course of disease. This effort will attempt to identify cellular and/or molecular immune biomarkers that associate with effectiveness of bacterial clearance and/or disease pathophysiology and employs genomic, proteomic and complex immune phenotyping approaches.
A second area of interest is the identification of immune targets in psoriatic arthritis and ankylosing spondylitis. We are utilizing samples from a well-characterized patient cohort to identify novel autoantigens. Our approach is to utilize state of the art proteomic and phage display based systems.
Lastly we are interested in the role of cellular elements of the immune response in controlling infection with gram-negative bacterial pathogens such as Salmonella typhimurium. This interest is driven not only because these bacteria cause significant acute disease but also due to the etiological link between infection with Salmonella and related species with the development of chronic autoimmune disease. We utilize a mouse model and have recently focused our attention on the role of the intestinal mucosal immune compartment in controlling oral infection. This effort has identified a new unrecognized subset of T cells residing within the epithelial barrier that expands following infection. Current efforts are focused on understanding the recognition properties and effector function of this T cell subset and determining if an analogous population exists in the human mucosa.
