Study the effect of components of destroyed streptococci on human blood monocyte functions related to processes of trans-endothelial migration in vitro. Materials and methods. Mononuclear leukocytes, isolated from blood of healthy donors, endothelial cells of EA.hy 926 line and supernatant of ultrasound disintegrated Streptococcus pyogenes (DSS) were the objects of the study. Evaluation of adhesion and monocyte migration, level of expression of adhesion molecules and phosphokinases on monocytes was carried out by flow cytometry using monoclonal antibodies. Cytokine concentration was determined by using standard commercial test systems in enzyme immunoassay. Results. Under the effect of DSS, expression of adhesion molecules CD162 and CD11b, as well as phospho-p38 MAPK changed, IL-6 and IL-8 secretion induction took place. DSS caused enhancement of migration and adhesive activity of monocytes, however, inhibited intensity of trans-endothelial migration. Conclusion. Products of destroyed streptococci have a multi-directional effect on human blood monocytes, that could be explained by the presence of components with varying biological activity in DSS.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучение влияния компонентов разрушенных стрептококков на функции моноцитов крови человека, связанные с процессами трансэндотелиальной миграции in vitro. Материалы и методы. Объектами исследования являлись мононуклеарные лейкоциты, выделенные из крови здоровых доноров, эндотелиальные клетки линии EA.hy 926 и супернатант разрушенных ультразвуковой дезинтеграцией Streptococcus pyogenes (СРС). Оценку адгезии и миграции моноцитов, уровня экспрессии адгезионных молекул и фосфокиназ на моноцитах проводили методом проточной цитометрии с использованием моноклональных антител. Концентрацию цитокинов определяли с использованием стандартных коммерческих тест-систем в иммуноферментном анализе. Результаты. Под влиянием СРС на моноцитах изменялась экспрессия адгезионных молекул CD162 и CD11b, а также фосфо-р38 МАРК, происходила индукция секреции IL-6 и IL-8. СРС вызывал усиление миграционной и адгезивной активности моноцитов, однако ингибировал интенсивность трансэндотелиальной миграции. Заключение. Продукты разрушенных стрептококков оказывают на функции моноцитов крови человека разнонаправленное действие, что может объясняться присутствием в составе СРС компонентов с разной биологической активностью.</p></trans-abstract><kwd-group xml:lang="en"><kwd>S. pyogenes</kwd><kwd>monocytes</kwd><kwd>endothelial cells</kwd><kwd>S. pyogenes</kwd><kwd>adhesion</kwd><kwd>transmigration</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>моноциты</kwd><kwd>эндотелиальные клетки</kwd><kwd>адгезия</kwd><kwd>трансмиграция</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Лебедева А.М., Старикова Э.А., Бурова Л.А. и др.
