Rodent models of rheumatoid arthritis.
The study of rheumatoid arthritis is greatly facilitated by animal models that enable investigation of a complex system involving inflammation, immunological tolerance, and autoimmunity. Although the models cover several species and pathogenetic mechanisms and can be classified as induced or spontaneous, all converge on arthritis. However, because each model features a different mechanism driving disease expression, the merits of each should be evaluated carefully in making the appropriate choice for the scientific question to be addressed. In addition, because the incidence and kinetics of disease vary by model, careful thought should be given to protocol design to minimize animal use.
