Phl p 4: An early indicator of grass pollen allergy?

Association between a low IgE response to Phl p 5 and absence of asthma in patients with grass pollen allergy

BACKGROUND The introduction of component-resolved diagnosis was a great advance in diagnosis of allergy. In particular, molecular allergy techniques allowed investigation of the association between given molecular profiles and clinical expression of allergy. We evaluated the possible correlation between the level of specific IgE (sIgE) to single components of Phleum pratense and clinical issues...

Nonanaphylactic synthetic peptides derived from B cell epitopes of the major grass pollen allergen, Phl p 1, for allergy vaccination.

Worldwide more than 200 million individuals are allergic to group 1 grass pollen allergens. We have used the major timothy grass pollen allergen Phl p 1, which cross-reacts with most grass-, corn-, and monocot-derived group 1 allergens to develop a generally applicable strategy for the production of hypoallergenic allergy vaccines. On the basis of the experimentally determined B cell epitopes o...

Multiple independent IgE epitopes on the highly allergenic grass pollen allergen Phl p 5

BACKGROUND Group 5 allergens are small proteins that consist of two domains. They belong to the most potent respiratory allergens. OBJECTIVE To determine the binding sites and to study allergic patients' IgE recognition of the group 5 allergen (Phl p 5) from timothy grass pollen using human monoclonal IgE antibodies that have been isolated from grass pollen allergic patients. METHODS Using ...

Single-Chain IgE Antibody Fragments Grass Pollen Allergen Phl p 1 Revealed with High-Density IgE Recognition of the Major

Atopic donor status does not influence the uptake of the major grass pollen allergen, Phl p 5, by dendritic cells

Dendritic cells (DCs) are sentinels of the immune system for antigen recognition and uptake, as well as presentation to naïve T cells for stimulation or priming. Internalization and endocytic degradation of allergens by DCs are important steps required for T cell priming. In the current study we investigated binding and internalization of purified recombinant non-glycosylated grass pollen aller...
