The mouse model of collagen-induced arthritis (CIA) is particularly advantageous for study, given the vast number of inbred strains available and their corresponding immunologic reagents. Disease induction is more complex than that in other autoimmune disease models—e.g., experimental autoimmune encephalomyelitis (EAE; unit 15.1)—in that CIA requires both the activation of T cells and the production of antibodies specific for both the immunogen and the autoantigen, murine CII.
This protocol is for the DBA/1JLacJ strain of mouse; see Background Information for discussion of susceptibility of various mouse strains to CIA.
