Alteration Of The Chemical Composition Of Human Immunoglobulin G By Free

Abstract

SUMMARY

Incubation with type 12 was shown to lead to marked alterations of the fucose, galactose, and total hexose content of human immunoglobulin G (IgG). Immunological studies showed at least partial identity of this altered IgG and normal IgG. Streptococcal antigen was not found in the altered immunoglobulin. We suggest that if such alterations occurred , the altered immunoglobulin might become autoimmunogenic or might possess the biological properties of immune complexes and thus be of immunopathological significance in post-streptococcal glomerulonephritis.
