Pru du 1, the Bet 1-homologue from almond, is a major allergen in patients with birch pollen associated almond allergy.

Background: Almond allergy is common and can manifest in two different forms. Primary almond allergy has been reported to be associated with sensitization to almond legumin Pru du 6. In birchendemic regions, there is a link between birch-pollinosis which is likely based on a cross-reactive Bet v 1 homologue, a yet unidentified allergen in almond.

Isotype-specific binding patterns of serum antibodies to multiple conformational epitopes of Bet v 1.

Background: Birch pollen is an important elicitor of respiratory allergy. The major allergen, Bet v 1, binds IgE exclusively via conformational epitopes.

Objective: We identified Bet v 1-specific epitope repertoires of IgE and IgG from birch pollen-allergic and nonallergic subjects.

Adjuvants and Vaccines Used in Allergen-Specific Immunotherapy Induce Neutrophil Extracellular Traps.

Aluminum hydroxide (alum) and monophosphoryl-lipid A (MPLA) are conventional adjuvants in vaccines for allergen-specific immunotherapy (AIT). Alum triggers the release of neutrophil extracellular traps (NETs) by neutrophils. NETs contain expelled decondensed chromatin associated with granular material and may act as danger-associated molecular patterns and activate antigen-presenting cells.
