The current study proposes a nanoparticle-based therapeutic approach to target the anti-oxidant defense system of arthritic Balb/c mice.Methods: Biogenic selenium nanoparticles (SeNPs) were synthesized by using Trachyspermum ammi seed extract and were evaluated for their toxicological, as well as their therapeutic potential in collagen-induced arthritic mice.Results: The tested doses of SeNPs had no significant toxic effects on liver, kidney, spleen, and serum biochemical parameters in comparison to healthy mice. The SeNPs treatment reduced the disease severity, as demonstrated by decreased paw edema along with reduced lymphocytic cellular infiltration in the histopathological findings. SeNPs also revealed dose-independent improvement in the redox state of inflamed synovium by significantly improving the activity of antioxidant enzymes in comparison to the arthritic controls.Conclusion: It is therefore concluded that nano-selenium in combination with TAE extract showed enhanced therapeutic efficacy as compared to their individual effects.Keywords: rheumatoid arthritis, collagen-induced arthritis, selenium nanoparticles, Trachyspermum ammi
