Aspergillus species (A. flavus and A. niger) are important sources of inhalant allergens. Current diagnostic modalities employ crude Aspergillus extracts which only indicate the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. We report a study on the identification of major and minor allergens of the two common airborne As...
The allergenicity of hazelnuts treated with different proteolytic enzymes was examined and compared by SDS-PAGE / immunoblotting and EASTinhibition experiments using sera of 16 hazelnut allergic individuals. 30 min treatment with the enzymes protease, elastase and trypsin eliminated the allergenicity of the hazelnut proteins, which can be shown by means of immunoblotting experiments. EASTinhibi...
BACKGROUND Trees belonging to the order of Fagales show a distinct geographical distribution. While alder and birch are endemic in the temperate zones of the Northern Hemisphere, hazel, hornbeam and oak prefer a warmer climate. However, specific immunotherapy of Fagales pollen-allergic patients is mainly performed using birch pollen extracts, thus limiting the success of this intervention in bi...
BACKGROUND Allergens are mostly composed of glycoprotein structures. It is believed that glycan-specific antibodies may lead to false-positive reactions in immunoassays. In this study we investigated the glycosylation state of grape allergens as well as the presence of antibodies to cross-reactive carbohydrate determinants (anti-CCDs) in sera from grape-sensitive individuals. METHODS Grape ex...
Skin inflammation in atopic dermatitis starts with Th2 and IgE-mediated responses against exogenous allergens and, for unknown reasons, resembles features of a Th1-driven reaction in the chronic stages. We report the characterization of a human protein, Hom s 4, recognized by IgE autoantibodies from atopic dermatitis patients. The complete Hom s 4 cDNA codes for a 54-kDa basic protein containin...
CD23, the low-affinity receptor for IgE, exists in membrane and soluble forms. Soluble CD23 (sCD23) fragments are released from membrane (m)CD23 by the endogenous metalloprotease a disintegrin and metalloprotease 10. When purified tonsil B cells are incubated with IL-4 and anti-CD40 to induce class switching to IgE in vitro, mCD23 is upregulated, and sCD23 accumulates in the medium prior to IgE...
BACKGROUND Art v 1, Amb a 4, and Par h 1 are allergenic defensin-polyproline-linked proteins present in mugwort, ragweed, and feverfew pollen, respectively. We aimed to investigate the physicochemical and immunological features underlying the different allergenic capacities of those allergens. METHODS Recombinant defensin-polyproline-linked proteins were expressed in E. coli and physicochemic...
