Abstract


Natural products have received revived interest via traditional remedies or alternative medicine used for the treatment of various diseases. Zanthoxylum piperitum (ZP) has been utilized in traditional medicine for various medicinal purposes. The present study was conducted to evaluate whether ZP modulates allergic inflammation both in vivo and in vitro. We examined the pharmacological effects of ZP on 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD) symptoms in mice. Additionally, in order to clarify the anti-inflammatory mechanisms of ZP, we elucidate the effect of ZP on the expression levels of inflammatory cytokines and nuclear factor-κB (NF-κB) in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). The results demonstrated that ZP attenuated AD clinical symptoms such as erythema, edema and dryness as well as histamine and IgE serum levels in DNCB-induced AD model mice. Additionally, ZP suppressed the expression of inflammatory cytokines and activation of NF-κB in AD-like skin lesions and stimulated HMC-1. These results provide experimental evidence that ZP may be useful candidate for treating allergic inflammation including AD.
