Важной характеристикой терапии модифицированными Т-клетками, экспрессирующими химерный антигенный рецептор (chimeric antigen receptor, CAR), является продолжительность персистенции CAR T-клеток в организме больного. Длительная рестимуляция CAR T-клеточного продукта in vitro с последующим анализом его субпопуляционного состава и цитотоксической активности является одним из способов моделирования поведения клеток в организме больных.</p></sec><sec><title>Цель</title><p>Цель: изучить иммунофенотип, показатели истощения и функциональные характеристики анти-CD19 CAR T-клеточных продуктов, полученных из клеток здоровых доноров и больных В-клеточным острым лимфобластным лейкозом (В-ОЛЛ), в условиях длительной рестимуляции in vitro.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Анти-CD19 CAR T-клеточный продукт получили из клеток 5 здоровых доноров и 3 больных B-ОЛЛ. Проведено изучение иммунофенотипа полученных клеточных продуктов в условиях повторяющейся антигенной рестимуляции in vitro с использованием таргетной клеточной линии NALM6, несущей антиген CD19, в течение 7–10 дней. В каждой точке эксперимента были оценены пролиферативная и цитотоксическая активность, экспрессия маркеров истощения и динамика изменения субпопуляционного состава CAR-Т-клеток памяти (иммунофенотип).</p></sec><sec><title>Результаты</title><p>Результаты. Анти-CD19 CAR T-лимфоциты обладали выраженной цитотоксической активностью вне зависимости от источника лимфоцитов (здоровые доноры/больные). В процессе длительной антигенной рестимуляции всех клеточных продуктов наблюдалось уменьшение доли наивных (TN) и эффекторных (TE) CAR T-клеток и увеличение доли клеток центральной (ТСМ) и эффекторной памяти (ТЕМ). CAR T-клетки демонстрировали повышение экспрессии маркеров истощения (PD1, TIM3) вне зависимости от происхождения клеток и соотношения эффектор : таргет.</p></sec><sec><title>Заключение</title><p>Заключение. Анализ цитотоксической активности и иммунофенотипического состава CAR T-клеточных продуктов в условиях длительной рестимуляции выявил тенденцию к снижению цитотоксической активности и отличия в динамике пролиферации и популяционного состава между клеточными продуктами, полученными от больных В-ОЛЛ и здоровых доноров.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. An important characteristic of therapy with modified T-cells expressing the chimeric antigen receptor (CAR) is the duration of CAR T-cell persistence in the patient’s body. Prolonged re-stimulation of CAR T-cell product in vitro with further analysis of its subpopulation composition and cytotoxic activity is one of the approaches to model cell behavior in patients.</p></sec><sec><title>Aim</title><p>Aim: to study the immunophenotype, exhaustion and functional characteristics of anti-CD19 CAR T-cell products derived from healthy donors and patients with B-cell acute lymphoblastic leukemia (B-ALL) at prolonged re-stimulation conditions in vitro.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Anti-CD19 CAR T-cell products were generated from 5 healthy donors and 3 patients with B-ALL. The immunophenotype of the obtained cell products was studied under conditions of repeated antigenic re-stimulation in vitro using the target cell line NALM6 carrying the CD19 antigen over 7-10 days. At each experimental timepoint, the following parameters were assessed: proliferative and cytotoxic activity, expression of exhaustion markers, and changes in the subpopulation composition of CAR T-memory cells (immunophenotype).</p></sec><sec><title>Results</title><p>Results. Anti-CD19 CAR T-cells had significant cytotoxic activity regardless of the lymphocyte source (healthy donors/patients). During prolonged antigenic re-stimulation of all products, a decrease in the proportion of naive (TN) and effector (TE) CAR T-cells, and an increase in the proportion of central (TCM) and effector memory (TEM) cells was observed. CAR T-cells showed increased expression of exhaustion markers (PD1, TIM3) irrespective of the origin of the cell and E:T ratio.</p></sec><sec><title>Conclusion</title><p>Conclusion. Analysis of cytotoxic activity and immunophenotypic composition of CAR T-cell products under conditions of prolonged re-stimulation revealed a trend toward decreased cytotoxicity, as well as differences in proliferation dynamics and population composition between cell products obtained from B-ALL patients and healthy donors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>анти-CD19 CAR T</kwd><kwd>CAR T-клеточная терапия</kwd><kwd>иммунофенотип</kwd><kwd>истощение</kwd><kwd>цитотоксичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anti-CD19 CAR T</kwd><kwd>CAR T-cell therapy</kwd><kwd>immunophenotype</kwd><kwd>exhaustion</kwd><kwd>cytotoxicity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в соответствии с государственным заданием «Разработка анти-BCMA CAR T-клеточного лекарственного препарата для нужд онкогематологии» РК № 125030703310–3 на выполнение научных исследований ФГБУ «НМИЦ гематологии» Минздрава России</funding-statement><funding-statement xml:lang="en">the study was performed in accordance with the State Assignment “Development of anti-BCMA CAR T-cell drug for the needs of oncohematology” RK № 125030703310-3 for the performance of scientiﬁ c research of the National Medical Research Center for Hematology</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">Maude S.L., Frey N., Shaw P.A., et al.
