Значимый проопухолевый эффект оказывают гранулоцитарные (Г-МС) и моноцитарные миелоидные супрессорные клетки (М-МС). Т-клеточный иммунный ответ может быть снижен в связи с развитием Т-клеточного истощения, характеризующегося экспрессией ингибиторных рецепторов PD-1, TIM-3 и др. Гранулоцитарный колониестимулирующий фактор (Г-КСФ) поддерживает генерацию и экспансию МС и может влиять на функциональные свойства Т-клеток. Целью нашей работы было исследовать возможное влияние стимуляции препаратами Г-КСФ на индукцию экспрессии PD-1 и TIM-3 Т-клетками больных ММ.</p><p>В исследование были включены 40 больных ММ, которым была проведена мобилизация гемопоэтических клеток-предшественников препаратами Г-КСФ (5 мкг/кг/день) в течение 4-5 дней. Содержание CD4+PD-1+, CD4+TIM-3+, CD8+PD-1+, CD8+TIM-3+Т-клеток, Lin-HLA-DR-CD33+CD66b+ГМС, CD14+HLA-DR-М-МС оценивали перед началом курса инъекций Г-КСФ (n = 33), после курса Г-КСФ в первый день сепарации гемопоэтических клеток-предшественников (n = 28) и через 3-6 мес. (n = 40) методом проточной цитометрии.</p><p>Относительное содержание Г-МС и М-МС было значимо выше у больных ММ после курса Г-КСФ. Через 3-6 мес. содержание Г-МС и М-МС снижалось до исходных значений. После курса Г-КСФ было отмечено увеличение содержания CD4+PD-1+Т-клеток по сравнению со значениями перед исследованием. Через 3-6 мес. после курса Г-КСФ содержание этой популяции не отличалось от исходных значений. Относительное количество CD4+TIM-3+, CD8+PD-1+, CD8+TIM-3+Т-клеток не изменялось после курса Г-КСФ. Не было выявлено значимых корреляционных связей между содержанием популяций МС и Т-клеток, экспрессирующих PD-1 и TIM-3, после курса Г-КСФ.</p><p>Мобилизация гемопоэтических стволовых клеток препаратами Г-КСФ у больных ММ сопровождается транзиторным увеличением популяций МС и изолированным увеличением CD4+PD-1+Тклеток.</p></abstract><trans-abstract xml:lang="en"><p>All types of immune cells are involved in the pathogenesis of multiple myeloma (MM). Granulocytic (G-MDSCs) and monocytic myeloid-derived suppressor cells (M-MDSCs) have significant protumor effects. The T cell immune response may be reduced due to the development of T cell exhaustion, characterized by the expression of inhibitory receptors PD-1, TIM-3, etc. Granulocyte colony-stimulating factor (G-CSF) supports the generation and expansion of MDSCs and can influence the functional properties of T cells. The purpose of our work was to investigate the possible effect of stimulation with G-CSF drugs on the induction of PD-1 and TIM-3 expression by T cells in patients with MM. The study included 40 patients with MM who underwent mobilization of hematopoietic progenitor cells with G-CSF drugs (5 mcg/kg/day) for 4-5 days. Content of CD4+PD-1+, CD4+TIM-3+, CD8+PD-1+, CD8+TIM-3+T cells, Lin-HLA-DR-CD33+CD66b+G-MDSCs, and CD14+HLA-DR-M-MDSCs was assessed before the start of a course of G-CSF injections (n = 33), after a course of G-CSF on the first day of separation of hematopoietic progenitor cells (n = 28) and after 3-6 months (n = 40) by flow cytometry. The relative content of G-MDSCs and M-MDSCs was significantly higher in patients with MM after a course of G-CSF. After 3-6 months, the content of G-MDSCs and M-MDSCs decreased to the initial values. After the course of G-CSF, an increase in the content of CD4+PD-1+T cells was noted compared to the values before the study. After 3-6 months, the content of this population did not differ from the initial values. The relative numbers of CD4+TIM-3+, CD8+PD-1+, and CD8+TIM-3+T cells did not change after a course of G-CSF. There were no significant correlations between the content of the populations of MDSCs and T cells expressing PD-1 and TIM-3 after a course of G-CSF.</p><p>Mobilization of hematopoietic stem cells by G-CSF in patients with MM is accompanied by a transient increase in MM populations and an isolated increase in CD4+PD-1+T cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гранулоцитарный колониестимулирующий фактор</kwd><kwd>миелоидные супрессорные клетки</kwd><kwd>Т-клетки</kwd><kwd>PD-1</kwd><kwd>TIM-3</kwd><kwd>множественная миелома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>granulocyte colony-stimulating factor</kwd><kwd>myeloid-derived suppressor cells</kwd><kwd>T cells</kwd><kwd>PD-1</kwd><kwd>TIM-3</kwd><kwd>multiple myeloma</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 20-75-10132.</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">Busch A., Zeh D., Janzen V., Mügge L.O., Wolf D., Fingerhut L., Hahn-Ast C., Maurer O., Brossart P., von Lilienfeld-Toal M.
