IgE Cross-Reactivity between Humulus japonicus and Humulus lupulus

No significant IgE cross-reaction was observed for Japanese and common hop pollen allergens, and development of allergy diagnostic and immunotherapeutic reagents based on Japanese hop pollen are urgently needed.

Comparison of the characterization of allergenic protein 3 (Pla a3) released from Platanus pollen grains collected in Shanghai during the spring of 2019 and 2020

The results suggested that more protein in the pollen grains was released onto the surface of pollen grains, revealing that air pollutants could enhance the expression of Pla a3 proteins in Platanus pollen.

Immune Effects of the Nitrated Food Allergen Beta-Lactoglobulin in an Experimental Food Allergy Model

Investigation of the effect of repeatedly ingested nitrated food proteins on the subsequent immune response in non-allergic and allergic mice using the milk allergen beta-lactoglobulin (BLG) as model food protein in a mouse model found that gavage of BLG to non- allergic animals increased interferon-γ and interleukin-10 release of stimulated spleen cells and led to the formation ofBLG-specific serum IgA.

Seasonal variation in the allergenic potency of airborne grass pollen in Bratislava (Slovakia) urban environment

Seasonal variation in the concentration of both grass pollen and Phl p 5 allergens as well as the ratio allergen/pollen (pollen potency) in the air of Bratislava during two consecutive years, 2019–2020 are evaluated.

Relationships between Mass Level of Allergenic Platanus acerifolia Protein 3 (Pla a3) and Redox Trace Elements in the Size-Resolved Particles in Shanghai Atmosphere

Allergenic pollen protein can be released from pollen grains and suspended in the air to cause allergenic reactions. However, the allergenic protein and its relationship with redox trace elements in



Effects of CO2 on Acer negundo pollen fertility, protein content, allergenic properties, and carbohydrates

The results indicate that increase in atmospheric CO2 concentrations can have a negative influence of some features of A. negundo airborne pollen that can influence the reproductive processes as well as respiratory pollen allergies in the future.

Allergenicity of recombinant profilins from Japanese hop, Humulus japonicus.

Profilin from Japanese hop pollen may play a minor role in the pathogenesis of pollinosis in Koreans, and two isoallergens of profilin that are highly conserved with those of mugwort, ragweed, and birch were identified in H. japonicus.

Common ragweed (Ambrosia artemisiifolia L.): allergenicity and molecular characterization of pollen after plant exposure to elevated NO2.

The data highlight a direct influence of elevated NO2 on the increased allergenicity of ragweed pollen and a direct correlation with an increased risk for human health.

Changes in the IgE-reacting protein profiles of Acer negundo, Platanus x acerifolia and Quercus robur pollen in response to ozone treatment

Modifications of O3 in protein content and immunoglobulin E (IgE)-binding profiles of Acer negundo, Platanus x acerifolia and Quercus robur pollen seem to be species dependent, but do not necessarily imply that increase allergenicity would occur in atopic individuals.

The Impact of Nitration on the Structure and Immunogenicity of the Major Birch Pollen Allergen Bet v 1.0101

The results implicate that nitration of Bet v 1.0101 might be a contributing factor to the observed increase in birch pollen allergy, and emphasize the importance of protein modifications in understanding the molecular basis of allergenicity.

Cloning, expression, and characterization of pollen allergens from Humulus scandens (Lour) Merr and Ambrosia artemisiifolia L

This study demonstrates a useful method for cloning homologous allergen genes across different species, particularly for little-studied species.

Subpollen particles: carriers of allergenic proteins and oxidases.

Structural insights into the IgE mediated responses induced by the allergens Hev b 8 and Zea m 12 in their dimeric forms

A novel monoclonal murine IgE (mAb 2F5), specific for rHev b 8, was produced, which was useful to provide evidence that profilin dimerization considerably increases the IgE-mediated degranulation in rat basophilic leukemia cells.
