  • Title: Relationship between complement activation and renal deposition of immune complexes made with IgG2a monoclonal antibodies.
    Author: Gonzalez ML, Waxman FJ.
    Journal: Clin Immunol; 2001 Sep; 100(3):362-71. PubMed ID: 11513550.
    Abstract:
    Previous studies identified a single murine monoclonal IgG2a anti-dinitrophenyl antibody that, when combined with the antigen, formed immune complexes (IC) that were preferentially deposited in glomeruli. The present study examined the clearance and organ localization in Balb/c mice of expanded panels of radiolabeled IC containing murine monoclonal antibodies. The results identified a second IgG2a antibody that formed IC with a predilection for renal deposition. IC made with the two IgG2a antibodies that were preferentially deposited in the kidney were the least efficient binders of human C1q or homologous murine C3b and C4b within the IgG2a panel. These observations suggest a new model of IC-mediated renal disease initiation in which relatively weak complement activation leads to inefficient IC clearance by complement receptor-bearing circulating cells and consequent IC deposition in tissues susceptible to IC-mediated injury.
