Cells from the body's immune system can on occasion react against normal endogenous proteins and thereby effect a reaction against certain body tissues. This abnormal immune response is termed autoimmunity. Ordinarily, a complex network of feedback loops keeps autoimmune reactions in check. However, under certain circumstances, normal control is lost and the aberrant immune reaction will result in disease.

Myasthenia gravis is an example of an autoimmune disease in which antibodies are produced against the acetylcholine receptors in the neuromuscular junction. The abnormal immune response results in the breakdown of junctional receptors, ultimately rendering patients weak and unable to move voluntary muscles. Rheumatoid arthritis is another autoimmune disease in which antibodies are secreted against a component of an individual's own immune globulins. These antibody-immune globulin conjugates (immune complexes) form precipitates in the joints of affected individuals. Phagocytic cells are in turn attracted to these sites, where they release enzymes that destroy surrounding tissue (inflammation). Immunosuppressive agents are often employed in debilitating cases of autoimmune disease to curb the production of autoanti-bodies.
