BACKGROUND Pollen extracts and chemically modified allergoids are used successfully in allergen immunotherapy (AIT). Recombinant extracts offer potential advantages with respect to pharmaceutical quality, standardization and dosing. A hypoallergenic recombinant folding variant of the major birch pollen allergen (rBet v 1-FV) was compared with an established native birch preparation. A pre-seaso...

Abstract Background Pollen‐food allergy syndrome (PFAS) is caused by the cross‐reaction of specific IgE to pollen allergens with similar contained in fruits, vegetable, and nuts. The representative allergen responsible for this pathogenesis‐related protein (PR)‐10. Specific test using Gly m 4, soybean PR‐10, widely used diagnose soy allergy. We aimed investigate whether 4‐specific useful predic...

This mini-review summarizes the available data of the air pollutants NO2 and ozone on allergenic pollen from different plant species, focusing on potentially allergenic components of the pollen, such as allergen content, protein release, IgE-binding, or protein modification. Various in vivo and in vitro studies on allergenic pollen are shown and discussed.

One expected effect of climate change on human health is increasing allergic and asthmatic symptoms through changes in pollen biology. Allergic diseases have a large impact on human health globally, with 10-30% of the population affected by allergic rhinitis and more than 300 million affected by asthma. Pollen from grass species, which are highly allergenic and occur worldwide, elicits allergic...

background: there are many therapeutic methods for allergic conditions. cpg oli-gonucleotides play a critical role in immunity via the augmentation of th1 and suppres-sion of th2 responses. objective: in the present study we aimed to estimate the effec-tiveness of intranasal administration of cpg odn plus chenopodium album allergen in allergic asthma compared with the administration of allergen...

The diagnosis and therapy of allergic disorders are usually performed with crude extracts which are a heterogeneous mixture of proteins with different allergenic potency. The knowledge of the allergenic composition is a key step for diagnostic and therapeutic options. Parietaria judaica pollen represents one of the main sources of allergens in the Mediterranean area and its major allergens have...

BACKGROUND Synthetic contiguous overlapping peptides (COPs) may represent an alternative to allergen extracts or recombinant allergens for allergen specific immunotherapy. In combination, COPs encompass the entire allergen sequence, providing all potential T cell epitopes, while preventing IgE conformational epitopes of the native allergen. METHODS Individual COPs were derived from the sequen...

REVIEWERS COMMENTS. Although it is not commercially available in the United States, SLIT for pollen allergy has gained widespread acceptance in Europe, and evidence supporting its safety and efficacy is accumulating. The promise of SLIT is that it might provide a safer and more-convenient alternative to subcutaneous immunotherapy while maintaining efficacy. Much of the literature supporting its...

Various allergens are implicated in the pathogenesis of allergic diseases in different regions. This study attempted to identify the most common allergens among patients with allergies based on the results of skin prick tests in different parts of Iran. Relevant studies conducted from 2000 to 2016 were identified from the MEDLINE database. Six common groups of allergen types, including animal, ...

Pollen allergens play important roles in plant development in addition to their allergenic nature for human. More than 10 groups of pollen allergens have been reported. Among them, Pollen_Ole_e_I (Ole), Pollen_allerg_1 (Allerg1) and Pollen_allerg_2 (Allerg2) domain-containing proteins are the majority of allergens. We have identified 114 pollen-allergen-like genes in rice genome by bioinformati...
