Кукурбитурилы являются макроциклическими кавитандами с определенным количеством гликолурильных фрагментов (n), определяющих размер полости данного соединения. На данный момент существует шесть синтезированных гомологов: 5, 6, 7, 8, 10 и 14. Отличаются друг от друга портальным размером и размером полостей. Характеризуются особыми физико-химическими и биологическими свойствами, такими как биосовместимость, стабильность, высокая способность к инкапсуляции химических соединений. Известно, что кукурбитурилы инкапсулируют молекулы путем формирования комплексов по типу «гость–хозяин», что позволяет высвобождать вещество из комплекса, повышать растворимость соединений и использовать кукурбитурилы как системы доставки лекарственных веществ. Иммуномодуляторная активность зависит от его специфических наноразмерных характеристик: функциональные группы, форма, размер, поверхность, растворимость в различных средах. Каждая наночастица, в зависимости от этих свойств, оказывает различные эффекты на клетки. Эффекты кукурбитурилов могут быть различными даже для одной субпопуляции клеток в зависимости от гомолога или дозировки. Взаимодействие клеток врожденного иммунитета с кукурбитурилами пока еще недостаточно изучены.</p><p>Целью этого исследования была оценка влияния кукурбит[n]урилов (n = 6, n = 7, n = 8) на клетки врожденного иммунитета – моноциты, NK-клетки, NKT-клетки.</p><p>Иммунологическое исследование включало выделение мононуклеарных клеток периферической крови условно здоровых доноров (n = 8) на градиенте плотности фиколл-урографина и проточную цитометрию с определением количества иммунокомпетентных клеток по классическим маркерам дифференциации этих клеток – CD3- CD16+CD56+ для NK-клеток, CD3+CD16+CD56+ для NKTклеток и CD3- CD14+ для моноцитов. Активацию моноцитов определяли по экспрессию поверхностного маркера HLA-DR.</p><p>Клетки культивировали 72 часа с добавлением кукурбитурилов CB[<xref ref-type="bibr" rid="cit6">6</xref>], CB[<xref ref-type="bibr" rid="cit7">7</xref>] в концентрациях 0,1, 0,3, 0,5 мМ и CB[<xref ref-type="bibr" rid="cit8">8</xref>] в концентрации 0,01 мМ, поскольку он имеет плохую растворимость. Было отмечено достоверное снижение количества NK-клеток (p &lt; 0,01 для исследуемых концентраций CB[<xref ref-type="bibr" rid="cit7">7</xref>]), увеличение количества NKT-клеток (p &lt; 0,04 и p &lt; 0,02 для концентраций CB[<xref ref-type="bibr" rid="cit6">6</xref>] и CB[<xref ref-type="bibr" rid="cit7">7</xref>] соответственно). Также наблюдалась тенденция к повышению экспрессии HLA-DR на моноцитах (p = 0,06 для CB[<xref ref-type="bibr" rid="cit6">6</xref>]).</p><p>Учитывая такое разностороннее действие кукурбитурилов, в перспективе можно рассматривать возможность использования кукурбитурилов в качестве иммуномодуляторов, противоопухолевых агентов, при аутоиммунных заболеваниях. </p></abstract><trans-abstract xml:lang="en"><p>Nanotechnology in immunology is a prospectively developing area in fundamental and practical medicine. Cucurbiturils are macrocyclic cavitands with a definite amount of glycoluril fragments (n) that determine the size of the cavity of these compounds. Nowadays, there are six synthesized homologues: 5, 6, 7, 8, 10 and 14. They differ from each other in the portal size and the size of the cavities. They are characterized by special physicochemical and biological properties, such as biocompatibility, stability, high ability to encapsulate chemical compounds. It is known that cucurbiturils encapsulate molecules by forming guest-host complexes, which allow the substance to be released from the complex and increase the solubility of the compounds. These advantages allow using cucurbiturils as drug delivery systems. Immunomodulatory activity of cucurbiturils depends on its specific nanoscale characteristics: functional groups, shape, size, surface, solubility in various media. Each nanoparticle depending on these properties has different effects on cells. The effects of cucurbiturils can be different even for one subpopulation of cells, depending on the homologue or dosage. The interaction of innate immune cells with cucurbiturils are not yet sufficiently characterized.</p><p>The aim of this study was to assess the effects of cucurbit[n]urils (n = 6, n = 7, n = 8) on innate immune cells – monocytes, NK-cells, NKT-cells.</p><p>The immunological recearch included the isolation of peripheral blood mononuclear cells from healthy donors (n = 8) on the density gradient of ficoll-urografin and flow cytometry with the determination of the amount of immunocompetent cells according to the classic markers of differentiation of these cells – CD3- CD16+CD56+ for NK-cells, CD3+CD16+CD56+ for NKT-cells and CD3- CD14+ for monocytes. Monocyte activation was determined by the expression of surface HLA-DR.</p><p>The cells were cultured for 72 hours with the addition of cucurbiturils CB[<xref ref-type="bibr" rid="cit6">6</xref>], CB[<xref ref-type="bibr" rid="cit7">7</xref>] at concentrations of 0.1 mM, 0.3 mM, 0.5 mM and CB[<xref ref-type="bibr" rid="cit8">8</xref>] at concentration of 0.01 mM, due to its poor solubility.</p><p>There were a significant decrease in the quantity of NK-cells (p &lt; 0.01 for the test concentrations of CB[<xref ref-type="bibr" rid="cit7">7</xref>]), an increase in the quantity of NKT-cells (p &lt; 0.04 and p &lt; 0.02 respectively for the concentrations of CB[<xref ref-type="bibr" rid="cit6">6</xref>] and CB[<xref ref-type="bibr" rid="cit7">7</xref>]). There was a tendency to increase the expression of HLA-DR on monocytes (p = 0.06 for CB[<xref ref-type="bibr" rid="cit6">6</xref>]).</p><p>Considering a variative effects of cucurbiturils, in the future it is possible to consider a possibility of using cucurbiturils as an immunomodulators, antitumor agents, in autoimmune diseases. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>кукурбитурилы</kwd><kwd>макроциклические соединения</kwd><kwd>иммунитет</kwd><kwd>врожденный иммунитет</kwd><kwd>моноциты</kwd><kwd>NK-клетки</kwd><kwd>NKT-клетки</kwd><kwd>проточная цитометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cucurbiturils</kwd><kwd>macrocyclic compounds</kwd><kwd>immunity</kwd><kwd>innate immune system</kwd><kwd>monocytes</kwd><kwd>NK-cells</kwd><kwd>NKT-cells</kwd><kwd>flow cytometry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Российский Научный Фонд</funding-statement><funding-statement xml:lang="en">This study was supported by the Russian Science Foundation according to the research project No. 19-15-00192.</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">Alam A., Saxena R.K.
