In the control CIA mice treated with saline, massive cellular infiltration and erosion of bone were observed in the ankle joint. In CIA mice treated with the highest dose of IFN-β (2.5 μg per injection per mouse), limited hyperplasia of the intimal lining layer and cell infiltration of the synovial sublining were detected and a decrease in bone erosions was observed. Infiltration of inflammatory cells of the joints was scored from 0 to 4 in a blinded manner as described in Materials and methods. A significant reduction in inflammatory cells was observed for the treatment groups treated with 2.5 μg and 1.25 μg IFN-β in comparison with controls (= 0.04). *Statistically significant difference.
