title: Immunological mechanisms of specific immunotherapy with pollen vaccines: implications for diagnostics and the development of improved vaccination strategies.
abstract: This review deals with specific immunotherapy performed with pollen vaccines. Pollen allergens, the immunological mechanism of allergic inflammation and the mechanisms behind successful specific immunotherapy treatment of seasonal pollen allergy shall be discussed. The different approaches to develop improved regimes for specific immunotherapy based on new diagnostic tools, improved pollen vaccines and alternative routes for administration of the vaccines will be highlighted. Diagnostic tools to select patients for specific immunotherapy and for monitoring the treatment are quantitative measurements of allergen-specific immunoglobulin E, G and G4 antibodies and component-resolved diagnostics based on immunoglobulin E binding to individual allergenic components. Future pollen vaccines may consist of hypoallergenic recombinant allergens and T-helper cell type 1-inducing immunostimulatory adjuvants. Both sublingual and nasal administration of pollen vaccines for specific immunotherapy may be used more in future.
