Brief research description:
There is an increasing awareness of the contribution of CNS-reactive antibodies in different neurological diseases. These antibodies penetrate brain tissue upon blood-brain barrier breach or early in development. Antibodies can bind to different extracellular or intracellular antigens and their contribution to tissue injury is often unclear. We aim to characterize novel CNS-reactive antibodies in different autoimmune diseases and analyze the mechanisms of autoantibody-mediated impairment of neuronal or glial cell function. Our studies provide important insights for biomarker discovery and for future therapeutic applications to prevent the pathogenic effects of CNS-reactive autoantibodies.
