    Abstract:
    Collagen type II (CII)-induced arthritis (CIA) can be induced in 78% of B10.RIII mice (H2r) by intradermal (id) immunization with CII of bovine origin in complete Freund's adjuvant (CFA), whereas immunization with CII of chick origin induces arthritis in less than 5% of these mice. Nevertheless, tolerization of B10.RIII mice with intravenously injected chick CII renders the animals resistant to induction of CIA by immunization with bovine CII. Such tolerization can be achieved either by intravenous injection of 500 micrograms chick CII 1 week prior to immunization with bovine CII in CFA or by such an intravenous injection of chick CII 2 weeks after immunization with bovine CII in CFA. Postimmunization treatment results in a significant decrease in the concentration of antibody to bovine CII. Preimmunization administration of chick CII causes a marked decrease in the antibody reactive with chick CII without a significant effect on the anti-bovine CII antibody concentration. In DBA/1 mice, a strain in which both bovine CII and chick CII can induce a high incidence of the disease, intravenous injection of bovine CII can also prevent arthritis induced by chick CII, even when given 7 or 14 days after immunization. The fact that chick CII as tolerogen is quite effective in preventing arthritis in B10.RIII mice, while as immunogen it is very ineffective in inducing arthritis in this strain, may be interpreted as evidence for interaction between different epitopes on CII in the pathogenesis of CIA.
