Увеличение толщины эпикардиальной жировой ткани (ЭЖТ) ассоциируется с развитием воспаления и сердечно-сосудистых осложнений, однако данные о взаимосвязи между утолщением ЭЖТ и количеством регуляторных Т-лимфоцитов отсутствуют.</p><p>Целью исследования являлось изучение содержания циркулирующих T-регуляторных лимфоцитов и  ядерной транслокации фактора FoxP3 у пациентов со стабильной ишемической болезнью сердца (ИБС) в зависимости от толщины эпикардиальной жировой ткани.</p></sec><sec><title>Методы</title><p>Методы. Обследовано 30 пациентов с хронической стабильной ИБС. Толщину ЭЖТ измеряли методом эхокардиографии. Пациенты были разделены на группы в зависимости от отсутствия и наличия утолщения ЭЖТ более 5  мм (группы  1 и  2 соответственно). Методом проточной цитометрии с  визуализацией определяли содержание T-регуляторных лимфоцитов и  уровень ядерной транслокации FoxP3. Методом иммуноферментного анализа в  сыворотке крови определяли содержание цитокинов и  высокочувствительного С-реактивного белка (вчСРБ).</p></sec><sec><title>Результаты</title><p>Результаты. В группе  2 выявлено увеличение содержания холестрола липопротеинов низкой плотности (р = 0,043), соотношения холестерола липопротеинов низкой плотности к холестеролу липопротеинов высокой плотности (р = 0,017) и концентрации вчСРБ (р = 0,044) и IL-1β (р = 0,005) и  снижение относительного и  абсолютного содержания T-регуляторных лимфоцитов (р = 0,020 и р = 0,026 соответственно), а также количества клеток с ядерной транслокацией FoxP3 (р = 0,018) по сравнению с группой 1. По данным множественной логистической регрессии концентрации вчСРБ, IL-1β и доля Т-регуляторных лимфоцитов в совокупности являлись предикторами наличия утолщения ЭЖТ.</p></sec><sec><title>Заключение</title><p>Заключение. Утолщение эпикардиальной жировой ткани у  пациентов с ИБС ассоциируется со снижением содержания T-регуляторных лимфоцитов в крови и ядерной транслокации фактора FoxP3 в них при сопоставимых антропометрических параметрах ожирения и выраженности коронарного атеросклероза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Increase ofthe epicardial adipose tissue (EAT) thickness isassociated with development of inflammation and cardiovascular complications, however, there is no data on the relationship between EAT thickening and the number of immunosuppressive regulatory T lymphocytes.</p></sec><sec><title>The aim</title><p>The aim. To study the number of circulating T regulatory lymphocytes and nuclear translocation ofthe FoxP3 transcription factor in patients with stable coronary heart disease (CHD) depending on the epicardial adipose tissue thickness.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. We examined 30 patients with chronic stable CHD. The EAT thickness was measured by echocardiography. Patients were divided into groups depending on the presence and absence of EAT thickening above 5 mm (groups 1 and 2, respectively). Imaging flow cytometry was used to determine the number of T regulatory lymphocytes and the level of FoxP3 nuclear translocation. The concentration of cytokines and high sensitivity C-reactive protein (hsCRP) was determined using enzyme-linked immunosorbent assay in blood serum.</p></sec><sec><title>Results</title><p>Results. Anthropometric indicators of obesity and the severity of atherosclerosis were comparable between groups. In group 2, there was an increase in low-density lipoprotein cholesterol concentration (p = 0.043), ratio of low-density lipoprotein cholesterol tohigh-density lipoprotein cholesterol (p = 0.017) and the concentration ofhsCRP (p = 0.044) andIL-1β (p = 0.005), adecrease in the number and relative count of Tregulatory lymphocytes (p = 0.020 andp = 0.026, respectively), aswellas thenumber of cells withFoxP3 nuclear translocation (p = 0.018) compared togroup1. According tomultiple logistic regression, the concentration ofhsCRP, IL-1β and T regulatory lymphocytes relative count in total were the predictors of EAT thickening (accuracy 80 %; sensitivity 75 %; specificity 84,6 %; AUC = 0.89).</p></sec><sec><title>Conclusions</title><p>Conclusions. Thickening of epicardial adipose tissue inpatients withcoronary heart disease is associated with a decrease in the number of T regulatory lymphocytes andFoxP3 nuclear translocation inthem in presence of comparable anthropometric parameters of obesity and the severity of coronary atherosclerosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эпикардиальная жировая ткань</kwd><kwd>Т-регуляторные лимфоциты</kwd><kwd>FoxP3</kwd><kwd>интерлейкин-1β</kwd><kwd>липиды</kwd><kwd>проточная цитометрия с визуализацией</kwd><kwd>атеросклероз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>epicardial adipose tissue</kwd><kwd>T regulatory lymphocytes</kwd><kwd>FoxP3</kwd><kwd>interleukin 1β</kwd><kwd>lipids</kwd><kwd>imaging flow cytometry</kwd><kwd>atherosclerosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда (грант № 23-25-00010).</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">Iacobellis G.
