Chitosan Nanoparticles Eugenol recognizes as a potent antioxidant that can use the first therapeutic chemical to treat rheumatoid arthritis (RA) instead of Methotrexate. The purpose of this study was to investigate the effects of Chitosan Nanoparticles Eugenol as a potent Nano-herbal agent in the healing process of experimental neonatal RA compared to Methotrexate. The neonatal Wistar rats induced rheumatoid arthritis in both genders were divided into sham, control, the treatment receiving Methotrexate, and the second treatment receiving encapsulated Eugenol by Chitosan Nanoparticles groups. Afterward, Malondialdehyde, for assessment of lipid peroxidation as an oxidative stress biomarker by assay kit, FOXO3 protein as an antioxidant up-regulating by western blotting and expression of the TGF-β and CCL2/MCP-1 genes by real-time PCR evaluation, supported by a cartilage histopathology analysis. Based on these results, Methotrexate and Eugenol encapsulated by Chitosan Nanoparticles, a significant decrease is observed in the serum level of MDA and FOXO3 protein expression in comparison to the control group. Additionally, Nanoparticle herbal agent and Methotrexate has a decreasing effect on the expression of TGF-β and MCP-1 genes and a significant positive correlation was observed between MCP-1 and TGF-β. Inflammation, synovial hyperplasia, and pannus formation were extreme in the Collagen Induced Arthritis rats. It can be concluded that Encapsulated Eugenol by Chitosan Nanoparticles and Methotrexate, probably by dint of their immunomodulatory, anti-inflammatory, and antioxidant potential has a protective effect against RA. Nano Eugenol is capable of delivering promising linesresults to treat autoimmune diseases such as RA can also be suggested.
