Выделяют два клинических варианта дебюта саркоидоза: острое/подострое течения саркоидоза (ОС, или синдром Лефгрена) и хроническую форму течения саркоидоза (ХС, или «не Лефгрен-синдром») с высоким риском развития фиброза легких. Целью данного исследования было изучение субпопуляционного состава «поляризованных» Т-хелперов центральной и эффекторной памяти у больных с острым (n = 19) и хроническим (n = 63) дебютом саркоидоза, контролем служили образцы периферической крови, полученные от 48 условно здоровых добровольцев. С использованием многоцветной проточной цитометрии было показано, что при ХС наблюдается достоверное снижение CD3+CD4+ лимфоцитов относительно как больных с ОС, так и группы контроля (38,94% (31,33-44,24) против 48,96% (43,34-53,54) и 47,63% (43,82-52,73), при р &lt; 0,001 в обоих случаях). При ХС в циркуляции снижается как относительное, так и абсолютное содержание «наивных» Т-хелперов, а также СМ и ЕМ Т-хелперов при сравнении с контрольными значениями. У больных с ОС отмечено увеличение доли и концентрации в периферической крови ЕМ-клеток, способных к миграции в периферические воспаленные ткани, при сравнении с ХС. При анализе Т-хелперов популяции TEMRA отмечено увеличение как относительного, так и абсолютного содержания клеток данной популяции у больных с ОС относительно контрольных значений, так и пациентов с ХС. Достоверные различия по содержанию Th1- и Th2-клеток были отмечены только у пациентов с ХС (9,64% (7,06-13,65) против 13,80% (11,24-18,03) в контроле при р &lt; 0,001, а также 11,96% (9,86-14,78) против 10,67% (9,13-12,98) в контроле при р = 0,048 соответственно). Достоверных различий по относительному содержанию CXCR5-CCR6+Th17 и CXCR5+ фолликулярным Т-хелперам (Tfh) отмечено не было. Для обеих групп пациентов с саркоидозом было показано снижение доли «не классических» Th17 и DN Th17 на фоне увеличения уровня DP Th17-клеток в рамках общего пула CXCR5-CCR6+ СМ Th, тогда как «классические» Th17 у пациентов с хроническим дебютом заболевания повышались. Сходная динамика изменения баланса между отдельными субпопуляциями Th17 была отмечена при исследовании CCR6 позитивных EM Th, способных покидать циркуляцию и мигрировать на периферию. Таким образом, полученные нами результаты подчеркивают важность баланса между различными субпопуляциями Th17-клеток при различных течениях саркоидоза, а также указывают на высокую значимость этих клеток как перспективных мишеней в терапии саркоидоза.</p></abstract><trans-abstract xml:lang="en"><p>Sarcoidosis is a multisystemic granulomatous disorder of unknown cause, characterized by formation of immune granulomas in various organs, mainly in lungs. Currently, two main phenotypes of pulmonary sarcoidosis are described, i.e., Lofgren’s syndrome (LS) is an acute form with favorable outcome, and non-Lofgren’s syndrome (nLS) is a chronic type of disease with a high risk of pulmonary fibrosis. Our study was aimed to investigate the balance of main “polarized” CD4+ central and effector memory T cells from treatment-naive patients with pulmonary sarcoidosis (LS (n = 19) and nLS (n = 63)) compared to healthy volunteers (HC, n = 48). This marker might be used as immunological markers for predicting severity of this disorder. Multicolor flow cytometry analysis demonstrated that the patients with nLS showed significantly low levels of relative and absolute numbers of CD3+CD4+ lymphocytes if compared to patients with LS and control group (38.94% (31.33-44.24) versus 48.96% (43.34-53.54) and 47.63% (43.82-52.73), p &lt; 0.001 in both cases). Moreover, patients with nLS had reduced frequencies and absolute numbers of “naive”, CM and EM Th cells if compared with healthy controls. Furthermore, the patients with LS showed increased relative and absolute numbers of peripheral blood EM Th cells, capable for migration to peripheral inflamed tissues, when compared with nLS. Finally, patients with LS had increased frequencies and absolute numbers of effector TEMRA Th cells as compared to HC and nLS. Next, significant differences Th1 and Th2 cells frequencies were shown between the patients with nLS and HC (9.64% (7.06-13.65) versus 13.80% (11.24-18.03) with p &lt; 0.001, and 11.96% (9.86-14.78) versus 10.67% (9.13-12.98) with p = 0.048, respectively). But there were no significant differences in the relative numbers of CXCR5-CCR6+Th17 and CXCR5+ follicular T helper cells (Tfh) between the groups. Finally, both groups of patients with pulmonary sarcoidosis contained low proportions of “non-classical” Th17 and DN Th17 cell, but increased levels of DP Th17 cells within total CXCR5-CCR6+ CM Th if compared with HC. Nevertheless, patients with nLS had increased frequency of “classical” Th17 in comparison with healthy controls. A very similar imbalance between different Th17 cell subsets was observed within total CXCR5CCR6+ effector memory Th, that were able to migrate from the bloodstream to the sites of infection, or tissue injury. Taken together, the data suggest that the proportions of Th17 cell subsets in pulmonary sarcoidosis can be evaluated as a diagnostic and/or prognostic marker in clinical practice and these cells could serve as a new therapeutic target.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>саркоидоз</kwd><kwd>Т-хелперы</kwd><kwd>дифференцировка Т-хелперов</kwd><kwd>Т-хелперы 17</kwd><kwd>Th17.1</kwd><kwd>проточная цитометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sarcoidosis</kwd><kwd>CD4+T cells</kwd><kwd>Th cell differentiation</kwd><kwd>Th17 cell subsets</kwd><kwd>Th17.1</kwd><kwd>flow cytometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РНФ № 22-24-20013</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Визель А.А., Визель И.Ю., Амиров Н.Б.
