Background/Aims: Camel milk (CM) has shown beneficial anti-inflammatory actions in several experimental and clinical settings. So far, its effect on rheumatoid arthritis (RA) has not been previously explored. Thus, the current work aimed to evaluate the effects of CM in Adjuvant-induced arthritis and air pouch edema models in rats, which mimic human RA. Methods: CM was administered at 10 ml/kg orally for 3 weeks starting on the day of Freund's adjuvant paw inoculation. The levels of TNF-alpha and IL-10 were measured by ELISA while the protein expression of NF-kappa Bp65, COX-2 and iNOS was detected by immunohistochemistry. The expression of MAPK target proteins was assessed by Western blotting. Results: CM attenuated paw edema, arthritic index and gait score along with dorsal pouch inflammatory cell migration. CM lowered the TNF-a and augmented the anti-inflammatory IL-10 levels in sera and exudates of arthritic rats. It also attenuated the expression of activated NF-kappa Bp65, COX-2 and iNOS in the lining of the dorsal pouch. Notably, CM inhibited the MAPK pathway signal transduction via lowering the phosphorylation of p38 MAPK, ERK1/2 and JNK1/2 in rat hind paws. Additionally, CM administration lowered the lipid peroxide and nitric oxide levels and boosted glutathione and total anti-oxidant capacity in sera and exudates of animals. Conclusion: The observed CM downregulation of the arthritic process may support the interest of CM consumption as an adjunct approach for the management of RA. (C) 2017 The Author(s) Published by S.
