Develop in vitro model for studying production of cytokines by monocyte cells infected
with Chlamydia trachomatis mediated by type III secretion system (TTSS). Materials and methods.
Strain C. trachomatis L2/434/Bu was used in the experiments, culture of human monocytes U-937
was infected by this strain. Level of inflammatory cytokines was measured on flow analyzer Bio-
Plex 200 (Bio-Rad Laboratories). Low molecular compound LHC-342 which belongs to the class
of heterocyclic compounds was used as TTSS inhibitor. Results. 24 hours after the infection with
C. trachomatis culture 8 analyzed cytokines are induced in U-937 cells (IL-1, IL-4, IL-6, IL-8,
IL-10, GM-CSF, IFN-, TNF). The most pronounced increase was observed for IL-8, GM-CSF
and IFN-. Introduction of TTSS inhibitor into the culture of infected cells suppressed chlamydia
growth, but addition of FeSO4 restored the growth of chlamydiae. And activity associated
with translocation of effector TTSS protein IncA to inclusion membrane was suppressed. Under
the conditions of the obtained model of TTSS inhibition during intracellular development of C.
trachomatis a significant decrease of 2 pro-inflammatory cytokines - IL-6 and IL-1 - was observed.
Conclusion. Cytokine response plays a key role in the protective immune response in
chlamydia infection but at the same time induces immunopathologic conditions. The data obtained
give reasons to assume role of C. trachomatis TTSS in the induction of this component of immune
response that requires further detailed studies.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Разработать модель in vitro для изучения продукции цитокинов моноцитарными
клетками, инфицированными Chlamydia trachomatis, опосредованную системой секреции
III типа (ССТТ). Материалы и методы. В экспериментах использовали штамм C.trachomatis
L2/434/Bu, которым заражали культуру человеческих моноцитов U-937. Уровень
воспалительных цитокинов измеряли на проточном анализаторе Bio-Plex 200 (Bio-Rad
Laboratories). В качестве ингибитора ССТТ использовали низкомолекулярное соединение
LHC-342, относящееся к классу гетероциклических соединений. Результаты. Через 24
часа после инфицирования культурой C.trachomatis в клетках U-937 индуцируются 8 анализируемых цитокинов (ИЛ-1, ИЛ-4, ИЛ-6, ИЛ-8, ИЛ-10, ГМ-КСФ, -Инф, ФНО-).
Наиболее выраженное увеличение наблюдали в случае ИЛ-8, ГМ-КСФ и -Ифн. Внесение
ингибитора ССТТ к культуре инфицированных клеток подавляло хламидийный рост, но
при добавлении FeSO4 рост хламидий восстанавливался. При этом активность, связанная
с транслокацией эффекторного белка CCTT IncA на мембрану включения, была подавлена. В условиях полученной модели ингибирования ССТТ при внутриклеточном развитии
C.trachomatis наблюдали значительное снижение уровня 2 провоспалительных цитокинов,
ИЛ-6 и ИЛ-1. Заключение. Цитокиновый ответ играет ключевую роль в протективном
иммунном ответе при хламидийной инфекции, но в тоже время, индуцирует иммунопатологические состояния. Полученные данные дают основание предполагать участие ССТТ
C.trachomatis в индукции данного звена иммунного ответа, что требует дальнейшего детального изучения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>type III secretion system</kwd><kwd>cytokines</kwd><kwd>Chlamydia infection</kwd><kwd>heterocyclic compounds</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>система секреции III типа</kwd><kwd>цитокины</kwd><kwd>хламидийная инфекция</kwd><kwd>гетероциклические соединения</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Buchholz K.R., Stephens R.S.
