We get a lot of questions about known AE antibodies. Identification of antibodies on a cellular level has led to a reclassification and renaming of many diseases. Note that many people who have AE are antibody negative, which most in the medical community agree is because all antibodies simply have not yet been discovered. The Center for Autoimmune Neurology at the Perelman School of Medicine at the University of Pennsylvania published a list of all know antibodies on their website. Click here to see the known antibodies, syndrome, and antigens associated with AE. Our great thanks to the medical staff at Upenn for their dedication to fighting AE.
