Open Access Abstract Collagen-induced arthritis CIA is a chronic inflammatory disease bearing all the hallmarks of rheumatoid arthritis . polyarthritis synovitis and subsequent cartilage bone erosions. One feature of the disease contributing to joint damage is synovial hyperplasia. The factors responsible for the hyperplasia are unknown however an imbalance between rates of cell proliferation and cell death apoptosis has been suggested. To evaluate the role of a major pathway of cell death - Fas CD95 FasL - in the pathogenesis of CIA DBA 1J mice with a mutation of the Fas gene Ipr were generated. The susceptibility of the mutant DBA-lpr lpr mice to arthritis induced by collagen type II was evaluated. Contrary to expectations the DBA-lpr lpr mice developed significantly milder disease than the control littermates. The incidence of disease was also significantly lower in the lpr lpr mice than in the controls 40 versus 81 P .
