Abstract

Recent developments in proteomic technologies have enabled the high-throughput, multiplex measurement of large panels of antibodies in biological fluids of patients with immune-driven diseases. Antigen microarrays are increasingly being used to delineate the natural history of autoantibody formation and epitope spread, and thus gain insight into the pathogenesis of autoimmune diseases, as well as into host immunity and its shortcomings. Characterization of autoimmunity that precedes the onset of clinically apparent disease has the potential to guide disease prevention using either conventional immunosupression or novel, antigen-specific tolerizing therapies. In addition, autoantibody profiling has the potential to identify molecular subtypes of a disease, which could allow for prediction of disease outcomes such as severity, tissue damage, and response to therapy.
