Unlabelled: Bet v 1, the European White Birch tree pollen allergen is responsible for a number of allergic responses in humans such as rhinitis, asthma and oral allergy syndrome. The allergen belongs to pathogenesis-related (PR) class 10 protein superfamily and exists in several naturally occurring isoforms. Limited structural information on Bet v 1 isoallergens and variants prompted us to carry out their in silico structural characterization. In this study, three-dimensional structures of Bet v 1 isoallergens were predicted followed by allergen-antibody docking with Bet v 1- specific human IgE. Further, molecular dynamics simulations were performed for the allergen-antibody complexes. In addition, in silico mutagenesis was carried out for the design of a hypoallergenic variant of Bet v 1. Our study aimed to elucidate the differential ability of Bet v 1 isoallergens in eliciting allergic responses based on structural features and also identified a potential hypoallergen allowing us to propose it as a promising candidate for treating birch pollen-induced allergy.

The hazel allergen Cor a 1 is a PR-10 protein, closely related to the major birch pollen allergen Bet v 1. Hazel allergies are caused by cross-reactive IgE antibodies originally directed against Bet v 1. Despite the importance of PR-10 proteins in allergy development, their function and localization in the plant remain largely elusive.

The apple allergy in Northern Europe is a cross-reaction to the birch pollen allergy. No correlation between the allergenicity of an apple variety and the content of the major apple allergen Mal d 1, a homologue to the Bet v 1 allergen in birch, could be found using ELISA, so far. Therefore, an impact of polyphenols and/or differences in the isoallergen profile are discussed.

Patients who suffer from birch pollinosis often develop adverse reactions to the consumption of fresh apples due to the structural similarity of the allergens Bet v 1 and Mal d 1 from birch and apples, respectively. A different allergenic potential for Mal d 1 isoallergens is postulated, but approaches to quantify the Mal d 1 isoallergen-specific are missing. Therefore, a bottom-up proteomics approach was developed to quantify Mal d 1 by stable isotope dilution and microHPLC-QTOF analyses.
