Extraction of house dust mite allergen, Der p 1, from dust.
A recent article in this journal found that the type of extraction buffer did not affect measured levels of the major group one allergen (Der p 1) from the house dust mite, Dermatophagoides pteronyssinus, in household dust samples (1). This differed from a previous study where about twice the levels of Der p 1 were found in borate-buffered saline extracts, compared to ammonium bicarbonate buffe...
متن کاملMolecular, Structural and Immunological Characterization of Der p 18, a Chitinase-Like House Dust Mite Allergen
BACKGROUND The house dust mite (HDM) allergen Der p 18 belongs to the glycoside hydrolase family 18 chitinases. The relevance of Der p 18 for house dust mite allergic patients has only been partly investigated. OBJECTIVE To perform a detailed characterization of Der p 18 on a molecular, structural and immunological level. METHODS Der p 18 was expressed in E. coli, purified to homogeneity, t...
متن کاملConversion of Der p 23, a new major house dust mite allergen, into a hypoallergenic vaccine.
Der p 23, a new, major house dust mite (HDM) allergen that is recognized by >70% of HDM-allergic patients, has high allergenic activity and, therefore, must be considered an important component for HDM-specific immunotherapy. We constructed and characterized a hypoallergenic Der p 23 vaccine for HDM immunotherapy. Three nonallergenic peptides from the C-terminal IgE epitope-containing part of D...
متن کاملThe Proinflammatory Potential of Nitrogen Dioxide and Its Influence on the House Dust Mite Allergen Der p 1.
Asthma and allergies are both major global health problems with an increasing prevalence, and environmental data implicate an influence of air pollutants on their development. The present study focuses on the influence of nitrogen dioxide (NO2) and the major allergen of the house dust mite Der p 1 on human nasal epithelial cells of nonallergic patients in vitro. Nasal epithelial mucosa samples ...
متن کاملSequence analysis of cDNA coding for a major house dust mite allergen, Der p 1. Homology with cysteine proteases
A cDNA clone coding for Der p 1, a major allergen from the house dust mite Dermatophagoides pteronyssinus, has been sequenced. It codes for a 222 residue mature protein with a derived molecular weight of 25,371 and contains 1 potential N-glycosylation site. In addition, the cDNA appears to code for a 13 residue proregion, and an incomplete signal peptide. The deduced sequence shows a high degre...
