Ингибиторные рецепторы и их лиганды (чек-поинт молекулы) являются негативными регуляторами иммунного ответа. Однако их роль в иммунной адаптации при беременности остается малоизученной. Цель исследования – оценить уровень экспрессии чек-поинт молекул (PD-1, CTLA-4, Tim-3) на периферических Т-клетках у беременных в сравнении с фертильными небеременными женщинами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование были включены 36 женщин во второй половине беременности без гестационных осложнений, у 12 из которых имелась экстрагенитальная патология. Контрольную группу составили 28 сопоставимых по возрасту фертильных небеременных. Относительное содержание CD8+PD-1+, CD8+TIM-3+, CD8+PD-1+TIM-3+, CD4+PD-1+, CD4+TIM-3+, CD4+PD-1+TIM-3+ T-клеток крови оценивали методом проточной цитометрии с использованием соответствующих моноклональных антител (BDBiosciences, США).</p></sec><sec><title>Результаты</title><p>Результаты. Относительное содержание CD4+Tim-3+ и CD8+PD-1+ Т-клеток, а также CD4+ и CD8+ Т-лимфоцитов, коэкспрессирующих PD-1 и Tim-3 в периферической крови беременных, статистически значимо превышало аналогичные показатели у небеременных. Возрастание CD4+Tim-3+ и CD8+PD-1+ Т-клеток регистрировалось как у беременных с наличием, так и отсутствием экстрагенитальной патологии. Однако беременные с экстрагенитальной патологией отличались более высоким содержанием CD8+PD-1+ и меньшим количеством CD8+Tim-3+ клеток, а также отсутствием (характерного для беременных) возрастания PD-1+Tim-3+ Т-клеток. Количество сопутствующих патологий прямо коррелировало с долей CD8+PD-1+ лимфоцитов и обратно – с долей CD8+Tim-3+ и CD4+PD-1+Tim-3+ клеток. Кроме того, экспрессия чек-поинт молекул ассоциировалась со сроком гестации (прямая корреляция выявлялась с содержанием CD8+Tim-3+, CD4+PD-1+Tim-3+ и CD8+PD-1+Tim-3+ клеток) и в меньшей степени с возрастом беременных (обратная зависимость с долей CD8+Tim-3+ клеток).</p></sec><sec><title>Заключение</title><p>Заключение. Беременные во второй половине гестации характеризуются повышенной экспрессией молекул PD-1 и Tim-3 на периферических Т-клетках. При этом сопутствующая экстрагенитальная патология влияет на характер экспрессии указанных молекул.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Inhibitory receptors and their ligands (also called checkpoint molecules) are important feedback regulators of the immune response. However, their role in immunological adaptation during pregnancy remains poorly understood.</p><p>The aim of the study was to evaluate the level of checkpoint molecule (PD-1, CTLA-4, Tim-3) expression in peripheral T cells in pregnant women compared with fertile non-pregnant women.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 36 women in the second half of pregnancy without pregnancy complications, 12 of whom had extragenital pathology. The control group consisted of 28 age-matched fertile non-pregnant women. The proportion of CD8+PD-1+, CD8+TIM-3+, CD8+PD-1+TIM-3+, CD4+PD-1+, CD4+TIM-3+, and CD4+PD-1+TIM-3+ was evaluated by flow cytometry using the corresponding monoclonal antibodies (BD Biosciences, USA).</p></sec><sec><title>Results</title><p>Results. The proportion of CD4+Tim-3+ and CD8+PD-1+ Т cells and CD4+ and CD8+ Т lymphocytes co-expressing PD-1 and Tim-3 in the peripheral blood of pregnant women was statistically significantly higher than in non-pregnant women. An increase in CD4+Tim-3+ and CD8+PD-1+ T cells was observed both in pregnant women with and without extragenital pathology. However, pregnant women with extragenital pathology were characterized by a higher CD8+PD-1+ count and a smaller number of CD8+Tim-3+ cells, as well as by a lack of an increase in PD-1+Tim-3+ T cells typical of pregnant women. The number of comorbidities was directly correlated with the proportion of CD8+PD-1+ lymphocytes and inversely correlated with the proportion of CD8+Tim-3+ and CD4+ PD-1+Tim-3+ cells. In addition, the expression of checkpoint molecules was associated with gestational age (a direct correlation was found with the proportion of CD8+Tim-3+, CD4+PD-1+Tim-3+, and CD8+PD-1+Tim-3+ cells) and to a lesser extent – with the age of pregnant women (an inverse relationship was found with the proportion of CD8+Tim-3+ cells).</p></sec><sec><title>Conclusion</title><p>Conclusion. Pregnant women in the second half of pregnancy are characterized by increased expression of PD-1 and Tim-3 molecules in peripheral T cells. At the same time, concomitant extragenital pathology affects the expression of these molecules.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Т-клетки</kwd><kwd>беременность</kwd><kwd>ингибиторные PD-1</kwd><kwd>TIM-3</kwd><kwd>CTLA-4 чек-поинт молекулы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>T cells</kwd><kwd>pregnancy</kwd><kwd>inhibitory PD-1</kwd><kwd>TIM-3</kwd><kwd>CTLA-4 checkpoint molecules</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках научной работы НИИФКИ (тема № 122011800353-4)</funding-statement><funding-statement xml:lang="en">The study was carried out within the research project of the Research Institute of Fundamental and Clinical Immunology (topic No.122011800353-4)</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">Schnell A., Bod L., Madi A. et al.
