My research interests are focused on the analysis of humoral autoimmune responses in Type 1 Diabetes. Autoantibodies are typically targeted to antigens which display high beta-cell specific expression, are components of the regulated secretory pathway, and contain trans-membrane domains. Utilizing a combined bioinformatic/molecular engineering strategy to define potential targets of T1D autoantibodies, we identified ZnT8 as a key autoantigen. We have developed and optimized radioimmunoprecipitation assays (RIAs) to detect ~65% of newly diagnosed patient sera containing ZnT8 autoantibodies (ZnT8A). Since ZnT8 is beta-cell specific it is an ideal candidate to monitor beta cell mass and engineer antigen-based regimens to induce tolerance as off-target complications would be minimal. Towards these goals we are molecularly mapping its major epitopes and characterizing its utility as a measure of disease progression.
