Creation of recombinant proteins, containing profilin and signal peptides which provide proteasomal and lysosomal degradation pathways of proteins. Materials and methods. Plasmid pET-Bet v 2, encoding Bet v 2 allergen, was used as a base vector. Two signal peptides: C-terminal fragment of ornithine decarboxylase (ODCsig) and N-terminal fragment of human invariant chain (Ii) — were cloned into this vector. Recombinant proteins were produced in BL21 (DE3) strain of E. coli. The recombinant protein was purified using NiNTA agarose. Immunological specificity of the recombinant proteins was estimated by means of immune-enzyme methods using sera of patients suffering from birch pollen allergy. Results. Bet v 2 allergen (profilin) of Betula pendula pollen was modified by immunoregulatory peptides in order to change the IgE/IgG response ratio. Ornithine decarboxylase proteasome degradation signal was used to enhance the Th1 response and human invariant chain signal directed to lysosomes was used in order to enhance Th2 response. The production system of recombinant allergen Bet v 2 preparation suitable for immunological tests was developed. The produced highly purified chimeric proteins preparations bound IgE antibodies of allergic to birch pollen patients' sera efficiently. Conclusion. The new chimeric allergens based on Bet v 2 protein of Betula pendula pollen were created and isolated.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. создание рекомбинантных белков, содержащих профилин и сигнальные пептиды, обеспечивающие протеасомный или лизосомный пути деградации белков. Материалы и методы. Б качестве базового вектора использовали плазмиду pET-Bet v 2, кодирующую аллерген Bet v 2. Б данный вектор клонировали два сигнальных пептида: C-концевой фрагмент орнитиндекарбоксилазы (ODCsig) и N-концевой фрагмент инвариантной цепи человека (Ii). Рекомбинантные белки нарабатывали в E. coli штамма BL21(DE3). Рекомбинантный белок очищали с использованием Ni-NTA агарозы. Оценку иммунологической специфичности рекомбинантных белков проводили иммуноферментным методом c использованием сывороток крови пациентов, страдающих аллергией на пыльцу березы. Результаты. Для изменения соотношения IgE/IgG ответа аллерген Bet v 2 (профилин) пыльцы березы повислой модифицирован иммунорегуляторными пептидами. Для усиления Тh1-ответа использован сигнал деградации на протеасоме орнитиндекарбоксилазы и для Тh2-ответа — сигнал направления в лизосомы инвариантной цепи человека. Разработана система по наработке препаратов рекомбинантного аллергена Bet v 2, пригодного для иммунологических тестов. Полученные высокоочищенные препараты химерных белков эффективно связывали антитела изотипа IgE сывороток крови больных с гиперчувствительностью к пыльце березы. Заключение. Были созданы и выделены новые химерные аллергены на основе белка Bet v 2 пыльцы березы повислой.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Betula pendula</kwd><kwd>Bet v 2</kwd><kwd>profilm</kwd><kwd>immunoregulatory signals</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>береза повислая</kwd><kwd>Bet v 2 профилин</kwd><kwd>иммунорегуляторные сигналы</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gafvelin G., Parmley S., Neimert-Andersson T. et al.
