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

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.

Study on Lowering the Group 1 Protease Allergens from House Dust Mites by Exposing to Todomatsu Oil Atmosphere

Todomatsu oil has been identified as an efficient inhibitor against Group 1 HDM allergens and a viable measure to improve indoor air quality.

Novel Approaches for Inhibiting the Indoor Allergen Der f 2 Excreted from House Dust Mites by Todomatsu Oil Produced from Woodland Residues

Todomatsu oil has been proven in vitro as a potential effective public health strategy to inhibit the allergenicity of Der f 2 by reducing its amount instead of the IgG binding capacity of a single protein.



Expression and purification of a major allergen, Pla a 1, from Platanus acerifolia pollen and the preparation of its monoclonal antibody.

Recombinant Pla a 1 was successfully expressed and purified, and exhibited positive immunoglobulin E‑binding to serum from patients allergic to P. acerifolia pollen, which suggested that specific anti‑Pla a 2 antibodies may be obtained, which can be used for the rapid detection of PlA a 1 allergens and in the preparation of vaccines against P. Acerifiola pollen.

Characterization of two pollen allergens of the London plane tree in Shanghai.

To purify and characterize the two major allergens and to confirm the immunological activities of these pollen allergens in Shanghai, P. acerifolia pollen extract was purified and two proteins were identified as pollen allergen Pla a 1 and PlA a 2 via mass spectrometry.

Subpollen particles: carriers of allergenic proteins and oxidases.

Expression, purification and identification of Pla a1 in a codon-optimized Platanus pollen allergen.

The present study was the first, to the best of the authors' knowledge, to obtain expression of the allergen recombinant protein, Pla a1, fused with a Strep-TagII via codon optimization and provided the basis for the preparation of allergens with high purity, recombinant hypoallergenic allergens and allergenic nucleic acid vaccines.

Size-segregated Allergenic Particles Released from Airborne Cryptomeria japonica Pollen Grains during the Yellow Sand Events within the Pollen Scattering Seasons

Cryptomeria japonica pollen is the most common pollen, which are scattering during each spring season in Japan. Japanese cedar (Cryptomeria japonica) pollinosis is one of seasonal allergic rhinitis

Platanus pollen allergen, Pla a 1: quantification in the atmosphere and influence on a sensitizing population

Allergic response in susceptible patients does not always coincide with the presence and magnitude of airborne pollen counts, which hinders accurate interpretation of the relationship between the amount of pollen inhaled and the patient's symptoms.

Ragweed Subpollen Particles of Respirable Size Activate Human Dendritic Cells

It is suggested that inhaled ragweed SPPs are fully capable of activating dendritic cells (DCs) in the airways and SPPs' NAD(P)H oxidase activity is involved in initiation of adaptive immune responses against innocuous pollen proteins.
