IL-33 is a new member of the IL-1 family that plays a role in allergic disease. In this study, we evaluated the potential on the inhibition of atopic dermatitis (AD) of anti-mouse IL-33 antibody (alpha IL-33Ab) using 2, 4-dinitrochlorobenzene (DNCB)-induced AD mice model. We treated mice with alpha IL-33Ab via subcutaneous injection of each DNCB treatment 1 h later from day 1 to day 33 for 14 times. A control group received tacrolimus. Skin lesion and scratching behavior were compared. Ear thickness, dermatitis score, eosinophils and mast cells infiltration, and serum IgE levels were also analyzed. Correlations between serum IL-33 as well as soluble(s) ST2 and AD disease activity index in human AD were also investigated. DNCB-induced AD-like mice treated with alpha IL-33Ab showed improved AD-like symptoms. Eosinophils and mast cells infiltration and serum IgE levels were also significantly reduced by alpha IL-33Ab. Our study suggests that blockade of IL-33 has a curative effect on AD.
