Newly designed hemagglutinin-Der p 2 chimera is a potential candidate for allergen specific immunotherapy

Publication date: Available online 21 October 2018Source: Life SciencesAuthor(s): Ivan Mrkić, Rajna Minić, Dragan Popović, Irena Živković, Marija Gavrović-JankulovićAbstractAimTo investigate the immunomodulatory potential of a chimera composed of the receptor-binding domain of hemagglutinin 1 (H1s) from Influenza virus and Der p 2 (D2) allergen for allergen-specific immunotherapy of house-dust mite allergy (HDM).Main methodsH1sD2 chimera and D2 allergen were produced by genetic engineering in E. coli. Recombinant antigens were extracted from inclusion bodies by urea, then refolded and purified by immobilized- metal affinity chromatography (IMAC). Purity was verified by 2D-PAGE and secondary structures were assessed by CD spectroscopy. IgE reactivity of H1sD2 and D2 was tested in wes...
