since 20th  century, when allergy was defined, an ongoing attempt for discovering the mechanisms underlying it and its treatment began. defining allergens as well as cells such as regulatory t-cells and characterizing the antibodies involved in the pathogenesis (including blocking antibodies) have helped very much towards a better understanding of the immunologic process.however, allergen speci...

Background Serine protease inhibitors (SPI) comprising 60-90 amino acid residues, are frequent in plants, and belong to the protein family PR-6. It has recently been shown that a SPI-variant of wheat acts as an important allergen in baker’s asthma but not in persons suffering from wheatinduced food allergy. The aim of this study was to elucidate the role of a recombinant SPI-variant of Hevea br...

Profilin from wheat (Triticum aestivum) has been identified as an allergen (Tri a 12). The recombinant 14 kDa protein was produced in Escherichia coli, purified and crystallized using the hangingdrop vapour-diffusion method. A diffraction-data set was collected in-house from a single crystal to a resolution of 3.3 Å. The crystals belonged to space group P3221, with unit-cell parameters a = b = ...

OBJECTIVE Allergic disease caused by airborne pollen is a major health problem in China. Intensive study on pollen allergens can be of great help for preventing and treating pollinosis. Four aspects of the study on pollen allergens in China including major allergic pollen in our country, analysis and purification of pollen allergen composition, recombinant pollen allergens and clinical applicat...

Type I allergy is a major health problem in industrialized countries where up to 15% of the population suffer from allergic symptoms (rhinitis, conjunctivitis, and asthma). Previously, we identified a cDNA clone that encoded a birch pollen allergen as profilin. Profilins constitute a ubiquitous family of proteins that control actin polymerization in eukaryotic cells; in particular, profilin par...

In Europe, hazelnuts (Corylus avellana) are a frequent cause of food allergies. Several important hazelnut allergens have been previously identified and characterized. Specific N-glycans are known to induce strong IgE responses of uncertain clinical relevance, but so far the allergenic potential of glycoproteins from hazelnut has not been investigated. The aim of the study was the molecular cha...

Children putatively immune to the large roundworm Ascaris lumbricoides were identified in an area of Nigeria where infection is hyperendemic. Immunity was associated with higher levels of serum ferritin, C-reactive protein, and eosinophil cationic protein, indicating ongoing acute phase or inflammatory processes. In contrast, children who were susceptible to the infection had little serological...
