Der p 23 - new major allergen of D. pteronyssinus

der p23











Der p 23 3D structure

Der p 23 is a 14 kDa D. pteronyssinus (house dust mite) allergen protein found in mite feces. It belongs to the family of peritrophin-like proteins and characterized by a chitin-binding activity. In sensitized patients, Der p 23 binds about 74 % of specific IgE and being classified as new major HDM allergen, alongside with Der p 1 and Der p 2. Due to its high allergenic activity, Der p 23 should be used as an important component for HDM-specific immunotherapy. Here, we propose abstracts of several publications shedding light to the molecular, immunological and clinical characteristics of this protein and its importance for diagnosing and treating HDM allergy.
