В геноме НР присутствуют гены группы СagA (cytotoxin-associated genes) - гены, ассоциированные с цитотоксином. Инфицирование CagA+ штаммами НР сопровождается продукцией провоспалительных цитокинов, имеющих ключевое значение в поддержании и развитии деструктивно-воспалительных изменений в организме. Целью настоящего исследования явилось изучение роли белков CagA в регуляции иммунного ответа и оценка иммунокорригирующего эффекта полипренилфосфата (ППФ) у мышей. Материалы и методы. Эксперименты выполнены на мышах самцах DBA весом 18-20 г. Использованы генно-модифицированные родственные штаммы живых бактерий E coli, отличающиеся наличием островка генов, кодирующего синтез белков CagA НР. В качестве источника ППФ использован препарат Фоспренил. Оценку субпопуляционного состава клеток селезенки проводили методом проточной цитофлуориметрии с использованием моноклональных антител. Количественное определение IL 10, TGF-β выполняли иммуноферментным методом. Пролиферативную активность спленоцитов определяли стандартным методом по включению3Н-тимидина в ДНК клеток. Результаты исследований свидетельствуют, что белки CagA НР вызывают поляризацию иммунного ответа по Th1-доминантному типу, что выражается в увеличении популяции CD4+клеток, Т-клеток экспрессирующих СD25+, и CD25+ Foxp3+ и усилении пролиферативного потенциала иммунокомпетентных Т-лимфоцитов. Введение CagA+ бактерий сопровождается увеличением уровня TGF-β, продуцируемого активированными Тreg клетками. Введение ППФ приводило к нормализации содержания CD4 и CD8 Т-клеток, снижению популяций CD25+, Foxp3+, CD25+ Foxp3+, увеличению IL- 10 в сыворотке. Таким образом, ППФ оказывает корригирующее воздействие на клеточные иммунные реакции, препятствует выраженной поляризации Th1 иммунного ответа, снижает популяционную активацию Тreg клеток. Полученные результаты свидетельствуют о возможном снижении провоспалительного иммунного ответа под воздействием ППФ.</p></abstract><trans-abstract xml:lang="en"><p>Helicobacter pylori (HP) bacteria have a wide range of pathogenicity factors. The HP genome contains genes of the CagA group (cytotoxin-associated genes). Infection with CagA-positive HP strains is associated with the production of pro-inflammatory cytokines, which are involved in the maintenance and development of destructive and inflammatory changes in the organism. Here we studied the role of CagA proteins in the regulation of the immune response in DBA mice and evaluated the corrective effect of polyprenyl phosphate (PP) on this process. Genetically modified strains of E. coli were used, differing by the presence of an island of genes encoding the synthesis of HP CagA proteins. The drug Phosprenyl was used as a source of PP. The subpopulation composition of spleen cells was evaluated by flow cytofluorimetry using monoclonal antibodies. The level of IL 10, TGF-β in blood serum was determined by the enzyme immunoassay. The proliferative activity of splenocytes was measured by the standard procedure based on the inclusion of3H-thymidine in the DNA. CagA HP proteins caused the polarization of the immune response by the Th1-dominant type, which was expressed by an increase in the population of CD4+cells, CD25+ and CD25+ Foxp3+ T cells and increase proliferation T- limphocytes. Inoculation of CagA + bacteria was accompanied by a quantitative increase in TGF-β produced by activated Treg cells. PP inoculation led to the normalization of the CD4 and CD8 T cells, a decrease in the populations of CD25+, Foxp3+, CD25+ Foxp3+ cells, and further increase in the IL-10 levels. Thus, PP corrected cellular immune response, prevented the pronounced polarization of the Th1 immune response, and reduced the activation of Treg population. The results obtained indicate a possible decrease in the pro-inflammatory immune response under the influence of PP.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Helicobacter pylori</kwd><kwd>белки CagА</kwd><kwd>полипренилфосфат натрия</kwd><kwd>иммунный ответ</kwd><kwd>регуляторные Т-клетки</kwd><kwd>цитокины</kwd><kwd>мыши</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helicobacter pylori</kwd><kwd>CagА proteins</kwd><kwd>sodium polyprenyl phosphate</kwd><kwd>immune response</kwd><kwd>regulatory T cells</kwd><kwd>cytokines</kwd><kwd>mice</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Shiota S., Suzuki R., Yamaoka Y.
