Objective: To explore the anti-inflammatory and antioxidant effects of caraway on atopic dermatitis (AD) in mice. Methods: AD was induced in two stages, including sensitization and challenge with the application of 2,4 dinitrochlorobenzene 2% and 0.2%, respectively. Clinical symptoms and histological analysis of the skin were assessed. The effects of caraway on oxidant/ antioxidant parameters as well as Th1- and Th2-related cytokines were also evaluated. Results: Caraway reduced the severity of dermatitis in AD-induced mice, as evidenced by significant inhibition of Th2-related cytokines (IL-4 and IL-13) and increased Th1-related cytokine (IFN-γ). Additionally, treatment with caraway significantly increased superoxide dismutase and catalase activity and decreased the malondialdehyde level in the serum of AD mice. Furthermore, caraway inhibited the differentiation of Th2 cells while favoring Th1 cell differentiation in the spleen via regulating their master transcription factors GATA3 and T-bet. Conclusions: Caraway could improve AD autoimmune responses and could be considered a potential candidate to treat AD disease.
