In this paper, we aimed to explore the potential mechanism underlying atopic dermatitis (AD) and its association with asthma. The BALB/c mice were randomly assigned to three groups, including the vehicle control (VD) group, the AD group, and the treatment (TR) group. The AD mice model was successfully constructed in the AD and TR group. The dermatitis severity scores and skin lesions were significantly increased in AD mice after DNCB application. Airway responsiveness in the AD group was significantly higher than in the TR group. The number of inflammatory cells was increased in skin lesions and bronchoalveolar lavage fluid (BALF) of AD mice. The levels of IL-4, IL-5, IFN-gamma, and OVA-IgE in BALF supernatants of mice in the AD group were higher than those in the VC group. All the changes in AD mice were decreased by tacrolimus. These results indicate that AD may be a significant risk factor for atopic asthma development.
