Высокодозная химиотерапия (ВХТ) с  трансплантацией аутологичных гемопоэтических стволовых клеток (ауто-ТГСК) является стандартом лечения больных множественной миеломой (ММ). Таргетная терапия, направленная против ингибиторных сигнальных молекул, представляется перспективным методом лечения ММ в посттрансплантационном периоде.</p><p>Цель — изучение динамики восстановления Т-клеток, экспрессирующих ингибиторные сигнальные молекулы PD-1 и TIM-3, у больных ММ в условиях лимфопении после ВХТ с ауто-ТГСК, а также оценка их функциональных свойств.</p></sec><sec><title>Методы</title><p>Методы. В  исследование включено 40  больных ММ, перенесших ВХТ с  ауто-ТГСК. Количество PD-1- и TIM-3-позитивных CD8+  и CD4+  Т-клеток и их функциональную активность по внутриклеточной экспрессии Ki-67, продукции гранзима В и интерферона-γ оценивали методом проточной цитометрии.</p></sec><sec><title>Результаты</title><p>Результаты. Выявлено более высокое относительное содержание PD-1+  и TIM-3+  клеток в субпопуляциях CD8+  и CD4+ Т-лимфоцитов в образцах костного мозга больных по сравнению с периферической кровью. CD8+ PD-1+  и CD4+ PD-1+ Т-клетки больных ММ обладали выраженным цитотоксическим и  цитокин-продуцирующим потенциалами. Функциональная активность CD8+ TIM-3+  и CD4+ TIM-3+  Т-клеток была снижена по сравнению с TIM-3-негативными субпопуляциями. Низкая функциональная активность также была выявлена в популяциях CD8+  и CD4+  Т-лимфоцитов, ко-экспрессирующих PD-1 и  TIM-3. Относительное количество Т-клеток, экспрессирующих PD-1 и  TIM-3, увеличивалось на день выхода из лейкопении после ауто-ТГСК, также были увеличены пролиферативная активность PD-1+  и  TIM-3+  CD4+  и  CD8+  Т-клеток и  цитотоксический потенциал PD-1+  и  TIM-3+  CD8+  Т-клеток по  сравнению с показателями до ауто-ТГСК.</p></sec><sec><title>Заключение</title><p>Заключение. PD-1-позитивные Т-клетки у  больных ММ являются активированными либо «ранними дисфункциональными» субпопуляциями лимфоцитов, тогда как CD8+ TIM-3+  и  CD4+ TIM-3+  Т-клетки, а  также субпопуляции, ко-экспрессирующие PD-1 и  TIM-3, характеризуются признаками Т-клеточного истощения. Для идентификации состояния Т-клеточного истощения у больных ММ необходима оценка субпопуляций Т-клеток, коэкспрессирующих PD-1, TIM-3 и другие ингибиторные сигнальные молекулы, и/или исследование их функциональных свойств. В  раннем посттрансплантационном периоде доля Т-клеток, экспрессирующих PD-1 и  TIM-3, возрастает за счет усиления их пролиферативного потенциала.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. High-dose chemotherapy (HDC) with autologous hematopoietic stem cell transplantation (auto-HSCT) is the standard of treatment for multiple myeloma (MM) patients. The post-transplant period appears to be promising for targeted anti-checkpoint therapy in MM.</p><p>Aim — to study the dynamics and functional properties of T-cells expressing inhibitory checkpoint molecules PD-1 and TIM-3 in patients with MM under conditions of lymphopenia after HDC with auto-HSCT.</p></sec><sec><title>Methods</title><p>Methods. The study included 40 patients with MM who underwent HDC with auto-HSCT. The counts of PD-1- and TIM3-positive CD8+ and CD4+ T-cells and their functional activity on the intracellular expression of Ki-67, production of granzyme B, and interferon-γ were assessed by fl ow cytometry.</p></sec><sec><title>Results</title><p>Results. Relative counts of patient PD-1+ and TIM-3+ subsets of CD8+ and CD4+ T-cells obtained from bone marrow samples were higher compared to peripheral blood. CD8+ PD-1+ and CD4+ PD-1+ T-cells of MM patients had a pronounced cytotoxic and cytokine-producing potential. The functional activity of CD8+ TIM-3+ and CD4+ TIM-3+ T-cells was signifi cantly reduced compared with TIM-3-negative subsets. Low functional activity was also detected in populations of CD8+ and CD4+ T-lympho cytes, co-expressing PD-1 and TIM-3. The frequencies of T-cells expressing PD-1 and TIM-3 increased signifi cantly on the engraftment day after auto-HSCT. The proliferative activity of PD-1+ and TIM-3+ CD4+ and CD8+ T-cells and the cytotoxic potential of PD-1+ and TIM-3+ CD8+ T-cells were also signifi cantly increased compared to the data prior auto-HSCT.</p></sec><sec><title>Conclusions</title><p>Conclusions. PD-1-positive T-cells in MM patients are related to activated or “early dysfunctional” but not exhausted subsets, while T-cells exhaustion is more analogous with CD8+ TIM-3+ and CD4+ TIM-3+ T-cells, as well as with subsets co-expressing PD-1 and TIM-3. To identify the state of T-cells exhaustion, it is necessary to evaluate T-cells subsets co-expressing PD-1, TIM-3, and other ICMs, and/or to study their functional properties. In the early post-transplant period, the proportion of Tcells expressing PD-1 and TIM-3 increases due to an increase in their proliferative potential.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>множественная миелома</kwd><kwd>трансплантация аутологичных гемопоэтических стволовых клеток</kwd><kwd>ингибиторные сигнальные молекулы</kwd><kwd>PD-1</kwd><kwd>TIM-3</kwd><kwd>Т-клеточное истощение</kwd><kwd>гомеостатическая пролиферация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple myeloma</kwd><kwd>autologous hematopoietic stem cell transplantation</kwd><kwd>inhibitory checkpoint molecules</kwd><kwd>PD-1</kwd><kwd>TIM-3</kwd><kwd>T-cell exhaustion</kwd><kwd>homeostatic proliferation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>грант Российского научного фонда (проект №  18-75-00050), бюджетные средства НИИФКИ (темы №  1021032423630-5, 1021062512013-6).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>the Russian Science Foundation grant No. 18-75-00050, budget of Research Institute of Fundamental and Clinical Immunology (themes No. 1021032423630-5, 1021062512013-6).</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">Kazandjian D.
