Collagen-induced arthritis (CIA) is an experimental autoimmune disease that can be elicited in susceptible strains of rodents (rat and mouse) and nonhuman primates by immunization with type II collagen (CII), the major constituent protein of articular cartilage. Because of the important similarities between CIA and rheumatoid arthritis, this experimental model of autoimmune arthritis has been the subject of extensive investigation in several laboratories. Protocols for CIA are described in this unit for both the mouse model and the rat model. In addition, protocols are included for the purification of CII from bovine articular joints and chicken sternums, for the purification of collagen a1(II) chains, and for the purification of fragments of these chains following cyanogen bromide (CNBr) digestion. The preparation of CII is a time-consuming procedure but is usually required because of the scarcity and expense of commercial sources of purified native CII. In addition, support protocols are provided for assessing the severity of inflammation following CIA and for measuring B and T cell responses to CII.The mouse model collagen-induced arthritis (CIA) is a widely studied autoimmune model of rheumatoid arthritis. In this model, autoimmune arthritis is induced by immunization with type II collagen (CII) emulsified in complete Freund's adjuvant. This unit describes the steps necessary for the acquisition, handling, and preparation of CII, in addition to the selection of mouse strains, proper immunization technique, and methods for evaluation of the incidence and severity of arthritis. In this model, the first signs of arthritis appear approximately 21 to 28 days after immunization. The protocols in this unit should provide the investigator with all the necessary information required to reproducibly induce a high incidence of CIA in genetically susceptible strains of mice, and to critically evaluate the pathology of the disease.
