Все CD3+CD8+ лимфоциты периферической крови на основании экспрессии CD45RA и CD62L были разделены на «наивные» клетки, клетки центральной (СМ) и эффекторной (ЕМ) памяти, а также «терминально-дифференцированные» CD45RA-позитивные эффекторные клетки (TEMRA). С использованием многоцветного анализа на указанных субпопуляциях проведен анализ коэкспрессии эффекторных (перфорин, гранзим В и CD57) и регуляторных (CD27, CD28, CD244 [2B4], CD279 [PD-1] и KLRG1) молекул. CD57 был выявлен на поверхности 2,39±0,31% «наивных» клеток и 5,45±0,91% клеток центральной памяти, тогда как среди CD45RA–CD62L– Тцит и TEMRA Тцит уже 26,53±2,20% и 51,43±2,55% клеток, соответственно, экспрессировали данный антиген. Среди «наивных» Тцит гранзим B и перфорин были обнаружены в составе цитоплазматических гранул у 4,22±0,36% и 5,30±0,43% клеток соответственно. Для СМ Тцит эти значения составили 10,09±1,17% и 24,90±3,10% клеток соответственно. Существенное увеличение экспрессии гранзима В и перфорина также было отмечено в линии «клетки эффекторной памяти → клетки TEMRA», когда эти величины достигли значений в 41,05±2,63% и 66,73±3,29%, а также 59,33±4,26% и 75,08±3,12% клеток соответственно. Для регуляторных молекул CD244 и KLRG1 также отмечена сходная тенденция к увеличению экспрессии по мере перехода клеток в эффекторные фазы созревания, тогда как костимуляционные молекулы CD27 и CD28 снижались в линии N → CM → EM → TEMRA. Максимальный уровень CD279 был отмечен в рамках клеток ЕМ. Показано, что CD57-позитивные клетки обычно содержат перфорин и гранзим B в составе своих цитоплазматическх гранул и не экспрессируют CD28 на своей поверхности, что позволяет использовать CD57 в качестве маркера зрелых эффекторных клеток для проведения многоцветного иммунофенотипирования. Полученные нами результаты по коэкспрессии указанных выше молекул позволяют предполагать, что на роль зрелых эффекторных цитотоксических Т-клеток периферической крови могут претендовать CD45RA+CD62L– лимфоциты, позитивные по CD244 и CD57, но не экспрессирующие костимуляционных молекул CD27 и CD28, а также не несущие на своей поверхности ингибиторных рецепторов CD279 и KLRG1.</p></abstract><trans-abstract xml:lang="en"><p>Cytotoxic T lymphocytes (CD3+CD8+, Tcyt) play a major role in protective immunity against intracellular pathogens and can eradicate malignant cells. As based on CD45RA and CD62L expression, the peripheral CD3+CD8+ blood lymphocytes were divided into "na ve" (N) cells, central memory (CM) and effector memory (EM), as well as "terminally-differentiated" CD45RA-positive effector cells (TEMRA). Using multicolor flow cytometry, a co-expression of effector (perforin, granzyme B and CD57) and regulatory (CD27, CD28, CD244 (2B4), CD279 (PD-1) and KLRG1) molecules was studied on all these subsets. CD57 was expressed in 2.39±0.31% “na ve” and 5.45±0.91% of central memory Tcyt. Meanwhile, within EM and TEMRA Tcyt subset, its expression was identified on the cell membranes of 26.53±2.20% and 51.43±2.55% of cells, respectively. Cytolytic effector molecules (granzyme B and perforin) were detected in cytoplasmic granules of 4.22±0.36% and 5.30±0.43% of na ve Tcyt, respectively. For CM cells, these values were 10.09±1.17% and 24.90±3.10%, respectively. Dramatic increases of granzyme B and perforin expression were observed in the “EM → TEMRA” cell lineage, when the relative number of granzyme B-positive cells increased to 41.05±2.63% and 66.73±3.29%, respectively, while perforin was detected in 59.33±4.26% and 75.08±3.12% of cells, respectively. For regulatory molecules, CD244 and KLRG1, the similar dynamics were observed, their expression increased from “na ve” to late maturation stages, while the expression of two main costimulatory molecules – CD27 and CD28, decreased in the lineage N → CM → EM → TEMRA cells. The highest level of CD279 was observed in EM cells. It was shown that CD57-positive cells contain perforin and granzyme B in their cytoplasmic granules and lack CD28 expression. Furthermore, CD57 can be used as a surrogate marker for multicolor immunophenotyping to identify most mature effector cells containing cytolytic enzymes. Our results on the co-expression of all the beforementioned molecules suggest that the most mature CD45RA+CD62L– effector peripheral blood cytotoxic T cells express CD244 and CD57, lack costimulation molecules CD27 and of CD28, as well as inhibitory receptors KLRG1 and CD279.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>проточная цитофлуориметрия</kwd><kwd>многоцветный анализ</kwd><kwd>цитотоксические Т-лимфоциты</kwd><kwd>дифференцировка</kwd><kwd>маркеры эффекторных клеток</kwd><kwd>ингибиторные рецепторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flow cytometry</kwd><kwd>multicolor immunophenotyping</kwd><kwd>cytotoxic T cell subsets</kwd><kwd>CD3+CD8+ maturation</kwd><kwd>effector molecules</kwd><kwd>inhibitory receptors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кудрявцев И.В.
