Dr. Rachel Caspi received her doctoral training in Israel and her postdoctoral training at the National Institutes of Health (NIH) in Bethesda, MD, USA. She is a tenured Senior Investigator at NIH and serves as a Section Head of the Immuoregulation Section and Chief of the Laboratory of Immunology, National Eye Institute, NIH. She also holds an Adjunct Professorship at the University of Pennsylvannia School of Medicine. Dr. Caspi's research centers on tolerance and autoimmunity to immunologically privileged retinal antigens in animal models of autoimmune uveitis, a potentially blinding human disease. She developed the mouse model uveitis, now in use worldwide. Her studies have elucidated many basic mechanisms of pathogenesis and helped to devise clinically relevant immunotherapeutic approaches. She is particularly well known for her work on effector and regulatory T cells in pathogenesis of ocular autoimmunity. The work she and her group have published is broadly applicable to autoimmunity in general. She is the recipient of numerous honors and awards, most recent of which was the 2010 Friedenwald award, one of the two highest awards in the field of vision research, and has authored and co-authored >200 publications.
The Section's interest is in cellular and molecular mechanisms involved in immune and autoimmune responses affecting the eye and vision. (1) Vision can be compromised by an inflammatory autoimmune disease known as uveitis, which destroys the neuroretina and is a major cause of blindness. We aim to understand the basic mechanisms that trigger and drive the disease. The studies center on development and maintenance of self-tolerance to immunologically privileged retinal antigens, on defining the natural triggers that lead to their pathological breakdown, and on experimental modulation of the pathogenic responses that follow. (2) Vision can also be compromised by damage to the surface of the eye. We study the mucosal immune responses of the ocular surface, which constitutes a barrier between the eye and the environment to define how the eye deals with diverse environmental stimuli. Because basic cellular and molecular mechanisms involved in disease are often difficult to study in humans, our experimental approaches rely heavily on animal models. Cutting edge approaches involving gene manipulated mice, multicolor flow cytometry, genomic and transcriptomic analyses, the study of the microbiome and bioinformatic predictions are used to dissect fundamental immune processes in health and disease. The approaches and conclusions are broadly generalizable to other autoimmune and inflammatory disease models and their human counterparts. The goal is to use the knowledge gained from these studies for designing novel and rational strategies for immunotherapy.
