autoimmune hypothesis,
a concept that defects occur in the body's immune system as one ages. As a result of the defects, a person's antibody-producing cells can no longer distinguish between "self " and "nonself " tissues. The body's own cells are then misidentified as foreign and are attacked by antibodies. However, circumstantial evidence links autoimmune diseases to preceding infections.
