В настоящее время все больше внимания уделяется детекции и оценке динамики содержания МВ лейкоцитарного происхождения. В этой связи большой интерес представляет определение МВ, образуемых NK-клетками, основной функцией которых является индукция апоптоза вирус-инфицированных и опухолевых клеток. В настоящее время нет прямых свидетельств о способности NK-клеток продуцировать МВ. Целью настоящей работы явилась оценка содержания МВ NK-клеток при помощи метода высокоточной проточной цитофлуориметрии. Установлено, что с помощью метода высокоточной проточной цитофлуориметрии возможно выявление МВ размером от 200 нм до 1000 нм, образуемых NK-клетками. Показано, что инкубация NK-клеток в присутствии TNFα не влияла на относительное количество МВ, однако приводила к повышению интенсивности экспрессии CD95 на МВ. Таким образом, метод высокоточной проточной цитофлуориметрии может быть использован для определения МВ и их фенотипа. </p></abstract><trans-abstract xml:lang="en"><p>As a result of activation and/or apoptosis, the cells can form microvesicles (MV) from 100 nm up to 1000 nm in size. Nowadays, the attention is being increasingly focused on dynamic detection and evaluation of leukocyte-derived microvesicles by their contents. In this regard, determination of microvesicles formed by NK cells is of utmost interest. The main function of these population is to induce apoptosis of virus-infected and tumor cells. At the present time, there is no direct evidence of the NK cells ability to produce microvesicles. This investigation was performed in order to estimate contents of NK cell-derived microvesicles using highprecision flow cytometric approach. It has been shown that the high-precision flow cytometry allows to detect microvesicles formed by NK cells, ranging from 200 to 1000 nm in size. It was demonstrated that incubation of NK cells in the presence of TNFα did not affect the relative value of microvesicles, however, being associated with increased intensity of CD95 expression on microvesicles. Hence, the high-precision flow cytometry can be used to detect microvesicles and to determine their phenotype. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>NK-клетки</kwd><kwd>проточная цитофлуориметрия</kwd><kwd>микровезикулы</kwd><kwd>микрочастицы</kwd><kwd>клеточная культура</kwd><kwd>NK-92</kwd><kwd>поверхностные рецепторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>NK cells</kwd><kwd>flow cytometry</kwd><kwd>microvesicles</kwd><kwd>microparticles</kwd><kwd>cell culture</kwd><kwd>NK-92</kwd><kwd>cell surface receptors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана грантом РФФИ № 17-04- 00679 (культивирование клеток) и грантом РНФ № 17-15-01230 (оценка фенотипических характеристик линии NK-92 и их микрочастиц).</funding-statement><funding-statement xml:lang="en">The present work was supported by the Russian Foundation for Basic Research grant No. 17-04- 00679 (cell cultures) and the Russian Science Foundation grant No. 17-15-01230 (evaluation of the NK-92 cell line phenotype and their microvesicles).</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">Agouni A., Ducluzeau P.
