autoantibody
harmful antibody that attacks components of the body called self antigens. Normally autoantibodies are routinely eliminated by the immune system's self-regulatory process-probably through the neutralization of autoantibody-producing lymphocytes before they mature. At times this process fails, and antibodies that react to self constituents proliferate.
