    Fabs fragments (Fabs) maintain binding ability to specific antigens, but lack the binding site for complements and for receptors on leukocytes that play a crucial role in Rheumatoid Arthritis (RA). In the present study, we investigated whether type II Collagen (CII)-Induced Arthritis (CIA) in mice was suppressed by anti-CII Fabs prepared by papain digestion of anti-CII antibodies. CIA was induced in DBA/1J mice by immunization with chicken CII and completes Freund’s adjuvant. To investigate the effect of anti-CII Fabs on the CIA model, mice were injected intraperitoneally with anti-CII Fabs 1 day before the first immunization. As a result, CIA was markedly inhibited by anti-CII Fabs; furthermore, the histological features of anti-CII Fabs-untreated mice included severe hyperplatic synnovium, cartilage and joint destruction, and leukocytic infiltration, whereas animals given anti..
