The autoantibodies raised in the DEBR rat were against normally expressed antigens as they were able to target epithelia in normal PVG/Ola rat tissue as well as lesional DEBR follicles. Nor were the autoantibodies species specific as they targeted the same epithelia in human scalp sections. Autoantibodies against striated muscle were particularly promi
