- autoimmune disease One of the most important traits of all normal individuals is their ability to recognize and react and eliminate them against many non-self antigens, while not detrimentally reacting to the antigenic substances that make up self. Is to have.
- the non-response of the body to autoantigens is called immunologic unresponsiveness or tolerance.
- Self-tolerance occurs by removing lymphocytes that may have specific receptors for autoantigens, or by inactivating the self-reacting function after contact with autoantigens. When a problem arises in inducing or maintaining self-tolerance, an immune response occurs to autoantigens, and the resulting disease is called an autoimmune disease.
