  • Identification of protein homologues and new allergenic families.

    • Main Results:

    • Fra e 1, an Ole e 1-like allergen, identified in ash pollen, with homologues of Ole e 3 and Ole e 6 also detected.
    • New allergenic species, Chenopodium album and Salsola kali, recognized due to desertification and greening programs.
    • Identification of a comprehensive panel of allergens from hypersensitizing sources.

    Conclusions:

    • Understanding new and existing pollen allergens is crucial for advancing allergy diagnosis and treatment.
    • Taxonomical relationships aid in identifying cross-reactive allergens.
    • Emerging allergenic plants pose new challenges for allergy management.
