Objective: To investigate the effects of RhTNFR: Fc in an established adjuvant arthritis (AA) rat model and the effects on cytokines production of peritoneal macrophage (PMφ). Methods: AA was induced by complete Freund adjuvant. AA rats were randomly divided into different groups and then treated with RhTNFR: Fc (1, 3, 9 mg·kg-1), or IgG-Fc (9 mg·kg-1), respectively after immunization. Arthritis was evaluated by global assessment, polyarthritis index, hind paw swelling, swollen joint count, X-ray of the paws and histopathological examination and histopathological scores. Activities of interleukin-1β (IL-1β) and interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in supernate of PMφ were assessed by ELISA. Results: Administration of RhTNFR: Fc significantly reduced the global assessment score, polyarthritis index, hind paw swelling and swollen joint count, ameliorated X-ray and histopathological manifestations, and decreased the expressions of IL-1β, IL-6 and TNF-α. Conclusion: Data presented here demonstrate that administration of RhTNFR: Fc significantly attenuates progression of experimental arthritis, and reduces proinflammatory cytokines of PMφ.
