Abstract | OBJECTIVE: METHODS: CpG, suppressive, and/or control ODN were injected into the knees of BALB/c mice. Joint swelling and inflammation were evaluated by physical measurement, by histologic analysis of joint tissue, and by magnetic resonance imaging. RESULTS: Immunostimulatory CpG DNA induced local arthritis, characterized by swelling of the knee joints, the presence of inflammatory cell infiltrates, the perivascular accumulation of mononuclear cells, and hyperplasia of the synovial lining. Administering suppressive (but not control) ODN reduced the manifestations and severity of arthritis up to 80%. CONCLUSION:
