Successful treatment of experimental glomerulonephritis with IdeS and EndoS, IgG-degrading streptococcal enzymes
Background. Anti-glomerular basement membrane (anti-GBM) disease often results in end-stage renal failure despite therapy with plasma exchange and immunosuppressive drugs. The newly discovered streptococcal enzymes IgG-degrading enzyme of S.pyogenes (IdeS) and endoglycosidase S (EndoS) act with remarkable specificity on circulating IgG. In this study, we investigate their ability in vivo to preven
