Purpose: Recently, interest is increasing in using prebiotics, which are nutrient ingredients of live microorganism that improve the intestinal environments by promoting the growth of beneficial gut microflora. Although numerous studies have demonstrated the beneficial effects of probiotics on atopic dermatitis (AD) development, few have examined preventive and therapeutic effects of prebiotics on the onset and progression of AD. Methods: In this study, we investigated therapeutic and preventive effect of prebiotics, including β-glucan and inulin, using an oxazolone (OX)-induced AD-like mouse model. Prebiotics were orally administered 2 weeks after the end of sensitization period (therapeutic study) and 3 weeks before the initial sensitization (prevention study). The physiological and histological alterations in the skin and gut of the mice were investigated. Results: In the therapeutic study, the severity of skin lesions and inflammatory responses were effectively reduced after administering β-glucan and inulin, respectively. The expression level of calprotectin was significantly decreased by approximately 2-fold (P < 0.05) in the skin and gut of prebiotics-treated mice compared to the control. In addition, epidermal thickness and the number of infiltrated immune cells were markedly reduced in the dermis of prebiotics-treated mice compared with to those in the OX-induced mice (P < 0.05). These findings were same as in the prevention study. Importantly, pre-administration of β-glucan and inulin prevented the progression of AD by promoting the growth of good bacteria in the gut of OX-induced AD mice. However, the co-administration of β-glucan and inulin did not show enhanced preventive effects on these alterations. Conclusions: Prebiotics has a therapeutic effect on AD in OX-induced AD mouse model. Moreover, our study suggests that prebiotics prevents the development of AD and this effect is associated with a change in gut microbiome.
