The data accumulated suggest that overt clinical types of this infection are associated with lost immunoregulation and increased pro-inflammatory cell-mediated immune response triggered by <italic>H. pylori</italic>-specific T helper cells. Here, we examined the degree of peripheral blood CD4<sup>+</sup> T cell maturity and related expression of chemokine receptors involved in migration to gastrointestinal tract (CCR9 and CCR6), as well as Тand B-cell zones of lymphoid organs (CCR7 and CXCR5). It was shown that overt <italic>H. pylori</italic>-infection was coupled to changes in expression pattern of chemokine receptors on T helper cells. In particular, percentage of mature CD4<sup>+</sup>CD45RO<sup>+</sup> T cells bearing CCR9 and immature CD4<sup>+</sup>CD45RO<sup>–</sup> Т cells expressing CXCR5 was increased in peripheral blood of patients with chronic gastroduodenitis. However, increased amount of activated mature CD4<sup>+</sup>CD45RO<sup>+</sup>ICOS<sup>+</sup> T cells was observed in patients with chronic gastroduodenitis comorbid with peptic ulcer that was also associated with elevated amount of mature CCR6<sup>+</sup> T helpers (mainly CD4<sup>+</sup>CD45RO<sup>+</sup>CCR7<sup>–</sup> CCR6<sup>+</sup> cells) and follicular T helper cells as well as emerging minor CD4<sup>+</sup>CD45RO<sup>+</sup>CXCR5<sup>+</sup>CCR6<sup>+.</sup>T cell subset, not affecting CD4<sup>+</sup>CCR9<sup>+</sup> Т cells. Thus, the data obtained evidence that tissue-specific T-helper cell migration is controlled separately in of <italic>H. pylori</italic>-associated diseases. </p></abstract><trans-abstract xml:lang="ru"><p><italic>Helicobacter pylori</italic> вызывает хроническую инфекцию приблизительно у половины населения планеты. Проявления инфекции, вызываемой этим микроорганизмом, варьируют от бессимптомного инфицирования до гастрита и язвенной болезни. Предполагается, что манифестные формы этой инфекции ассоциированы с утратой иммунорегуляции и усилением провоспалительного клеточного иммунного ответа, индукторами которого являются специфичные к <italic>H. pylori</italic> Т-хелперы. В этой работе мы оценивали степень зрелости СD4<sup>+ </sup>Т-лимфоцитов крови и экспрессию на них хемокиновых рецепторов, участвующих в миграции в желудочно-кишечный тракт (CCR9 и CCR6), Т- и В-клеточные зоны лимфоидных органов (CCR7 и CXCR5). Показано, что при манифестных формах <italic>H</italic><italic>. </italic><italic>pylori</italic><italic>-</italic>инфекции наблюдается изменение экспрессии хемокиновых рецепторов на Т-хелперах, которое зависит от формы заболевания. При хроническом гастродуодените в крови увеличивается содержание зрелых CD4<sup>+</sup>CD45RO<sup>+ </sup>клеток c рецептором CCR9, и незрелых CD4<sup>+</sup>CD45RO<sup>-</sup> клеток, несущих рецептор CXCR5. При сочетании хронического гастродуоденита с язвенной болезнью наблюдается усиление активации зрелых Т-хелперов, что проявляется в увеличении количества СD4<sup>+</sup>CD45RO<sup>+</sup>ICOS<sup>+</sup> клеток. Также у этих пациентов увеличивается содержание зрелых Т-хелперов, несущих рецептор CCR6 (в основном за счет наиболее зрелых CD4<sup>+</sup>CD45RO<sup>+</sup>CCR7<sup>-</sup>CCR6<sup>+ </sup>клеток) и клеток с фенотипом фолликулярных Т-хелперов, появляется минорная группа CD4<sup>+</sup>CD45RO<sup>+</sup>CXCR5<sup>+</sup>CCR6<sup>+ </sup>клеток. В то же время, у пациентов с язвенной болезнью отсутствует увеличение количества CD4<sup>+</sup>CCR9<sup>+ </sup>лимфоцитов в крови. Полученные данные свидетельствуют о различиях в управлении тканеспецифической миграцией Т-хелперов при данных заболеваниях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>T lymphocytes</kwd><kwd>chemokine receptors</kwd><kwd>peptic ulcer disease</kwd><kwd>gastritis</kwd><kwd>duodenitis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Т-лимфоциты</kwd><kwd>рецепторы хемокинов</kwd><kwd>язвенная болезнь</kwd><kwd>гастрит</kwd><kwd>дуоденит</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
