Introduction: Collagen induced arthritis (CIA) is a mouse model of rheumatoid arthritis marked by persistent inflammation and enhanced osteoresorption at the affected joints as well as systemic osteopenia due to increased activation of osteoclast progenitors (OCP). Abundantly secreted chemokines presumably attract OCPs to the inflamed sites. Our goal was to identify chemotactic signals important for OCPs recruitment in CIA.Methods: After obtaining approv...

Rheumatoid arthritis (RA) is characterised by periarticular bone destruction leading to permanent disability. Some other forms of arthritis, such as arthritis in systemic lupus erythematosus (SLE), rarely produce bone lesions. Corresponding to that, inactivation of Fas produces a murine SLE-like phenotype, but alleviates bone loss during antigen-induced arthritis (AIA). Aim of this study was to identify cell populations differentially regulated in non-resorptive vs. resorptive...
