The overall goal of the current research in my laboratory is to better understand the pathogenesis of the organ-specific autoimmune blistering diseases, such as bullous pemphigoid. Bullous pemphigoid (BP) is an blistering skin disease skin characterized by development of autoantibodies against BP180, a cell-substrate attachment protein. Early studies of the pathogenesis of BP were focused on autoantibodies of the IgG class; however, findings from our work and others have made it clear that IgE class autoantibodies also play a critical role in this disease process. We have shown that 90% of BP patients produce IgE autoantibodies that target the same small antigenic region of BP180 (termed NC16A) that is recognized by IgG autoantibodies. Further, BP IgE, when passively transferred into a xenograft murine model, can replicate the early phase of BP lesion development. This was the first demonstration of the pathogenicity of human IgE in an autoimmune disease. Treatment of basophils isolated from BP patients with the NC16A peptide was shown to induce specific degranulation of the cells, suggesting one mechanism by which IgE may contribute to lesion development. Recently we have utilized our research on IgE for the basis of a clinical trials of anti-IgE therapy in BP. Our future goals are to further delineate the role of IgE autoantibodies and effectors cells such as eosinophils and mast cells in BP and to utilize this information to identify additional novel therapies for autoimmune diseases.
As a physician-scientist one of my major goals is to translate findings from the laboratory into improved diagnostics and or therapies for patients.
