- Autoantibodies are immune system proteins that attack the body's own tissues or organs.
- Autoantibodies represent a failure by the immune system to distinguish between foreign proteins and the body's own tissues.
- Autoimmune disorders may be organ specific as in Graves' disease, or systemic, as in vasculitis.
