Abstract
Background: Atopic dermatitis (AD) is one of inflammatory skin diseases that is characterized by intense pruritus and relapsable eczematous lesions. The hallmarks of AD are defects of epidermal barrier and immunoglobulin E (IgE)-mediated sensitization to several environmental allergens, and immune disorder mediated by an imbalance towards T-helper-2 (Th2) response. Melittin (Mel), a major component of Bee venom, has been studied in various inflammatory diseases including liver cirrhosis, atherosclerosis, and acne. However, beneficial effects of Mel on AD-like animal have not been explored. Therefore, we investigated the anti-atopic effects of Mel. Methods: AD was induced on shaved back of BALB/c by using ovalbumin (OVA) patch. Mel was treated epicutaneously or intraperitoneally. After agent treatment, skin lesions and sera were extracted from sacrificed mice. Skin tissues were divided and used for H&E staining, Quantitative real-time PCR, and Western blot. Cytokines and IgE in the sera were determined by ELISA. Results: OVA-induced skin thickening and inflammatory infiltration were decreased in Mel-treated group. Mel prevented OVA-induced filaggrin deficiency. Furthermore, Mel ameliorated OVA-induced imbalanced inflammatory mediators. Conclusions: This study has shown that Mel inhibits OVA-induced AD-like symptoms in mice. The OVA can contribute crucially to the AD-like cutaneous symptoms, such as skin thickening, mast cells infiltration, filaggrin deficiency, exaggerated serum-IgE, and increased inflammatory mediators. However, Mel ameliorated the OVA-induced AD-like cutaneous symptoms and inflammatory mediators leading to the progression of AD. Furthermore, this study may be the first evidence that Mel can be used for anti-inflammatory effects on OVA-induced AD. Therefore, it is suggested that Mel is regarded as an alternative therapeutic agent for AD.
