Outline of Final Research Achievements

Epicutaneous sensitization has been considered as an important route for sensitization to allergens not only in atopic dermatitis but also towards other allergic diseases such as asthma (atopic march). Allergen sources such as mites and pollen produce or contain proteases, which can stimulate various types of cells. In this study, we established a murine model of epicutaneous sensitization to protease allergen and demonstrated that the protease activity of epicutaneously administered antigen markedly promoted sensitization and skin inflammation towards development of atopic march in airway.
