Question

Quizplus · Accepted Answer

Autoantibodies are antibodies that are produced by the immune system and are directed against the body's own proteins or antigens. This can lead to autoimmune diseases where the immune system attacks and damages the body's own tissues. Autoantibodies are not produced by T cells, nor are they involved in allergic reactions or tissue rejection reactions. They also do not represent the first step in immunological competence.
