В настоящее время выделяют два основных клинических варианта дебюта саркоидоза: вариант острого/подострого течения саркоидоза (ОС, или синдром Лёфгрена) c более благоприятным прогнозом, а также хроническая форма течения саркоидоза (ХС, или «не Лёфгрен-синдром») с высоким (около 20%) риском развития фиброза легких. Целью данного исследования было изучение фенотипических характеристик регуляторных Т-лимфоцитов (Treg) периферической крови больных с острым (n = 11) и хроническим (n = 46) дебютом саркоидоза, контролем служили образцы периферической крови, полученные от 26 условно здоровых добровольцем. С использованием многоцветной проточной цитометрии было показано, что при ОС уровень Т-клеток снижается относительного группы контроля, а при ХС уменьшается уровень CD3+CD4+ клеток при сравнении с контролем. Более того, при ХС как относительное, так абсолютное содержание Treg в периферической крови достоверно ниже значений контрольной группы (2,83% (2,47; 3,36) против 3,33% (2,79; 3,84) при p = 0,021 и 37 кл/мкл (29; 52) против 50 кл/мкл (42; 65) при p = 0,004 соответственно). Относительное содержание CD39-позитивных клеток в рамках общей популяции Treg возрастает с 39,52% (11,55; 46,34) как при хроническом (до 51,02% (38,20; 61,62), p &lt; 0.001), так и при остром (до 48,64% (41,46; 63,72), p = 0,007) дебюте саркоидоза. Анализ экспрессии CD39 и CD73 основными субпопуляциям Treg не выявил достоверных различий по относительному содержанию позитивных клеток между всеми группами в рамках «наивных» CD45R0-CD62L+) клеток. Вместе с тем уровень CD39+ клеток среди CD45R0+CD62L+ Treg у больных как ОС, так и ХС достоверно (p &lt; 0,001 и p = 0,004 соответственно) превышал контрольные значения (69,66% (61,92; 79,34) и 67,62% (61,92; 79,34), соответственно, против 47,55% (15,74; 65,32)). В случае CD45R0+CD62LTreg, способных покидать кровоток и мигрировать в очаги воспаления, увеличение относительного содержания CD39-позитивных Treg было отмечено лишь при сравнении ХС и группы контроля (61,79% (55,12; 73,09) и 57,27% (16,03; 66,98) соответственно, при p = 0,006). Полученные нами результаты указывают, что при саркоидозе в циркуляции увеличивается уровень CD39+Treg, способных эффективно подавлять иммунные реакции за счет утилизации провоспалительного АТФ и инициации каскада реакций, приводящих к формированию противоспалительного аденозина.</p></abstract><trans-abstract xml:lang="en"><p>Sarcoidosis is a disorder of unknown etiology characterized by development of necrosis-free epithelioid cell granulomas in various tissues. There are two main phenotypes of pulmonary sarcoidosis (PS): Lofgren’s syndrome (LS) is an acute form with favorable outcome, while non-Lofgren’s syndrome (nLS) is a chronic type of disease that can lead to pulmonary fibrosis in 20% of cases.</p><p>Our study was aimed at investigating changes in the main cell-surface differentiation antigens on peripheral blood regulatory T cells (Tregs) from the patients with first diagnosed PS without treatment (LS, n = 11) and nLS (n = 46) compared to healthy volunteers (HC, n = 26).</p><p>These indexes might be used as immunological markers for predicting severity of this disorder. Flow cytometry analysis of peripheral blood cell samples demonstrated that the nLS patients had decreased relative numbers of CD3+ cells vs healthy controls, as well as diminished CD3+CD4+ cells vs HC and LS patients. Furthermore, the relative and absolute Treg numbers were also decreased in nLS group vs HC (2.83% (2.47; 3.36) vs 3.33% (2.79; 3.84), p = 0.021), and 37 (29; 52) cells vs 50 (42; 65), p = 0.004, respectively) per one microliter of peripheral blood. Relative number of CD39-positive Тregs in chronic vs acute sarcoidosis patients was associated with 51.02% (38.20; 61.62) vs 48.64% (41.46; 63.72) that was significantly (p &lt; 0.001 and p = 0.007, respectively) higher than in HC (39.52% (11.55; 46.34). We have found that “naïve” (CD45R0-CD62L+) Тregs did not significantly differ in percentage of CD39- and CD73-positive cells in all the groups tested. Moreover, CD45R0+CD62L+ Тregs in LS and nLS patients contained significantly more CD39-positive cells (69.66% (61.92; 79.34) and 67.62% (61.92; 79.34), respectively, compared to 47.55% (15.74; 65.32) in HC (p &lt; 0.001 and p = 0.004, respectively). In case of CD45R0 + CD62LTregs able to exit from the circulation and migrate to the site of inflammation, an increased percentage of CD39-positive subset was noted only in patients with chronic sarcoidosis and HC (61.79% (55.12; 73.09) and 57.27% (16.03; 66.98), p = 0.006). Enhanced CD39 expression on Tregs seems to be related to chronic immune response, so that antigen elimination becomes impossible due to Treg overactivation, as shown in patients with sarcoidosis and some other chronic autoimmune and infectious disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>саркоидоз</kwd><kwd>регуляторные Т-лимфоциты</kwd><kwd>экспрессия CD39</kwd><kwd>проточная цитометрия</kwd><kwd>многоцветный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sarcoidosis</kwd><kwd>regulatory T cells</kwd><kwd>CD39 expression</kwd><kwd>flow cytometry</kwd><kwd>multi-color immunophenotyping</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">Визель И.Ю.
