The self-nonself concept as a basis for immune complex to replace "autoimmune diseases"

Abstract

The remarkable history of the 1951 pp 66 year old woman with gastric adenocarcinoma is reviewed. After subtotal gastrectomy she survived for 22 years without any metastases. Presumably the artificially induced high titer IgG, anti-P1 proved to be cytotoxic in two stages: (1) binding of anti-P1 to the terminal fifth sugar, galactose, and (2) the action of cellular immunity in the form of killer T derived lymphocytes containing receptors for IgG molecules. An identical mechanism may be operative in inducing abortions in the pp pregnant woman with a P1 fetus. P1 illegitimate glycolipid (GL) red cell antigen and Forssman (Fs) tissue in adenocarcinoma suggest the self-nonself concept because these are genetically foreign to the host. This concept applies also to numerous "autoimmune" diseases such as RA, lupus, glomerulonephritis, Coombs positive hemolytic anemia and other diseases with immune complexes (ICs) of 20--22 Svedberg units deposited as lesions with tissue damage. In the presence of the GL antigens (ABO, P, Fs), the normal serum contains antibodies for the missing antigen(s). The predicted anti-Fs was present in about 80% of normal employees of ages 18--70. In cancer sera the incidence was 35--40%. On testing normal sera b...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
