A Mouse Model of Atopic Dermatitis

Atopic dermatitis (AD) is a chronic or chronically relapsing, pruritic inflammatory skin disease. The incidence of AD has dramatically increased for the past three decades in industrialized countries. We established a highly efficient method to induce AD-like skin lesions using repeated epicutaneous treatments with house dust mite allergen and staphylococcal enterotoxin B (SEB). The dermatitis-induced mice showed increased serum IgE levels that were similar to human AD patients and also treatable with dexamethasone. This mouse AD model has been used in a vaccinia virus infection study. It will also be useful to study pathogenic processes of AD and to evaluate the efficacy of a drug candidate. In this chapter, we describe the detailed method that can induce AD-like skin inflammation in multiple mouse strains.
