В исследование включены биологические образцы больных злокачественными новообразованиями, получавших вакцинотерапию на основе аутологичных дендритных клеток (ДК). Для индукции пролиферации антигенспецифических Т-лимфоцитов (n=227) использовали незрелые ДК (n=46) и зрелые ДК (n=56). Для изучения противоопухолевой цитотоксической активности in vitro генерированных ЦТЛ (n=18) использовали аутологичные опухолевые клетки меланомы кожи (n=10) или сарком (n=8) пациентов в аналитической системе xCELLigence®. Секрецию цитокинов и цитолитических белков изучали методом мультиплексного анализа, субпопуляционный состав эффекторных Т-лимфоцитов определяли методом проточной цитометрии.</p></sec><sec><title>Результаты</title><p>Результаты. В работе показано, что зрелые ДК (CD83+CD1a-) отличаются высокой экспрессией молекул, презентирующих антиген (HLA-DR) и обеспечивающих миграцию ДК в лимфатические узлы (CCR7), а также костимулирующих молекул CD80 и CD86, по сравнению с незрелыми ДК (CD83-CD1a+). Установлено, что индукция зрелыми ДК стимулирует рост относительного содержания пролиферирующих Т-клеток по сравнению со стимуляцией незрелыми ДК (р&lt;0,001) и специфическим РТА+ опухолевым лизатом (р&lt;0,001). При изучении цитотоксической активности эффекторных Т-лимфоцитов разработана 2D in vitro модель с использованием аналитической системы xCELLigence® и выявлено 2 типа взаимодействия: 1) лабораторная модель № 1 – снижение клеточного индекса (CI) культуры клеток аутологичной опухоли в присутствии активированных эффекторных Т-лимфоцитов; 2) лабораторная модель № 2 – отсутствие изменений CI культуры клеток аутологичной опухоли при ее кокультивировании с активированными эффекторными Т-клетками по сравнению с контролем (72 ч наблюдения). Результаты демонстрируют цитотоксическую активность антиген-специфических Т-лимфоцитов, что обусловлено высоким содержанием терминальнодифференцированных цитотоксических Т-лимфоцитов (TEMRA), ЦТЛ, продуцирующих GrB, и профилем секреции цитокинов.</p></sec><sec><title>Заключение</title><p>Заключение. Разработаны требования к качеству персонализированной аутологичной ДКВ, включающие контроль иммунофенотипических характеристик, проведена оценка функциональной активности Т-лимфоцитов при индукции зрелыми вакцинными ДК. Разработан лабораторный регламент количественной оценки цитотоксической активности антиген-специфических Т-лимфоцитов в отношении аутологичной опухоли с использованием аналитической системы xCELLigence®, что позволит проводить персонализированный мониторинг и может прогнозировать эффективность проводимого лечения ДКВ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study: development of in vitro laboratory models to evaluate quality parameters and specific efficacy of dendritic cell vaccine (DCV).</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Biological samples of malignant tumor patients treated with autologous dendritic cell vaccine (DC) were included into the study. Immature DCs (n=46) and mature DCs (n=56) were used to induce proliferation of antigen-specific T lymphocytes (n=227). Autologous tumor cells from skin melanoma (n=10) or sarcoma (n=8) patients in the xCELLigence® assay system were used to study the in vitro antitumor cytotoxic activity of generated CTLs (n=18). The secretion of cytokines and cytolytic proteins was studied by multiplex analysis. The subpopulation composition of effector T-lymphocytes was determined by flow cytometry.</p></sec><sec><title>Results</title><p>Results. We revealed that mature DCs (CD83+CD1a-) had a high expression of antigen presenting molecules (HLA-DR) and those providing migration of DCs into lymph nodes (CCR7) as well as costimulatory molecules CD80 and CD86 as compared to immature DCs (CD83-CD1a+). Induction of mature DCs was found to stimulate an increase in the relative content of proliferating T cells compared with stimulation of immature DCs (p&lt;0.001) and specific PTA+ tumor lysate (p&lt;0.001). When studying cytotoxic activity of effector T-lymphocytes, we developed 2D in vitro models using xCELLigence® analytical system and revealed 2 types of interaction: 1) in vitro model № 1 – decrease in cell index (CI) of autologous tumor cell culture in the presence of activated effector T lymphocytes; 2) in vitro model № 2 – no change in CI of autologous tumor cell culture when co-cultured with activated effector T cells compared to control (72 h observation). The results demonstrated cytotoxic activity of antigen-specific T lymphocytes due to high content of terminally differentiated cytotoxic T lymphocytes (TEMRA), GrB-producing CTLs, and cytokine secretion profile.</p></sec><sec><title>Conclusion</title><p>Conclusion. Requirements for the quality of personalized autologous DCs, including control of immunophenotypic characteristics were developed, and functional activity of Tlymphocytes during induction of mature vaccine DCs was evaluated. A laboratory procedure was developed for quantitative assessment of cytotoxic activity of antigen-specific T-lymphocytes against autologous tumor using the xCELLigence® analytical system, thus allowing for personalized monitoring and predicting the effectiveness of DСV treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>клеточный продукт</kwd><kwd>параметры качества</kwd><kwd>раково-тестикулярные антигены</kwd><kwd>дендритные клетки</kwd><kwd>антиген-специфические Т-лимфоциты</kwd><kwd>лабораторная модель</kwd><kwd>xCELLigence</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cell product</kwd><kwd>quality parameters</kwd><kwd>cancer testicular antigens</kwd><kwd>dendritic cells</kwd><kwd>antigen-specific T-lymphocytes</kwd><kwd>laboratory model</kwd><kwd>xCELLigence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РНФ в рамках научного проекта № 22-25-00723 (Соглашение №22-25-00723 от 29.12.2021)</funding-statement><funding-statement xml:lang="en">This study was supported fnancially by the Russian Science Foundation within the scientifc project № 22- 25-00723 (Agreement № 22-25-00723 of 29.12.2021)</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">Мельникова Е.В., Меркулова О.В., Чапленко А.А., Меркулов В.А.
