ТКР изучались на клетках опухоли и эндотелия, однако наличие данных рецепторов на лимфоцитах не было показано. Целью настоящего исследования было изучение экспрессии рецепторных тирозинкиназ на субпопуляциях лимфоцитов у здоровых добровольцев и больных ПКР до и после удаления первичной опухоли.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: в исследование были включены 19 больных ПКР рТ1-Т3N0/N+M0/M+, подвергнутых нефрэктомии, и 10 здоровых добровольцев. Образцы крови собирали однократно у здоровых доноров и дважды у больных ПКР непосредственно перед и через 180 дней после хирургического вмешательства. Выделение лимфоцитов и проточная цитометрия выполнялись по стандартным методикам. Проводился сравнительный анализ уровней экспрессии ТКР на периферических лимфоцитах здоровых добровольцев и больных ПКР, а также при ПКР в динамике до и после операции. Выполнялся поиск корреляций между исходной экспрессией ТКР на лимфоцитах больных ПКР и характеристиками опухолевого процесса, а также прогнозом заболевания.</p></sec><sec><title>Результаты</title><p>Результаты: на CD45+ мононуклеарных клетках периферической крови, а также субпопуляциях лимфоцитов CD3+ и CD8+ у здоровых добровольцев и больных ПКР, не получавших лечение, экспрессируются ТКР VEGFR-1, -2, -3, FGFR2, PDGFRα, β. Различий уровней экспрессии всех изученных ТКР между субпопуляциями лимфоцитов у пациентов с ПКР не выявлено (p &gt; 0,05 для всех). Уровень экспрессии ТКР на периферических клетках CD45+ у больных ПКР до лечения достоверно ниже, чем у здоровых добровольцев (р &lt; 0,05 для всех). Степень снижения экспрессии ТКР коррелировала с категорией рТ и наличием опухолевого венозного тромбоза. Через 180 дней после удаления первичной опухоли у больных ПКР отмечено достоверное увеличение уровней экспрессии VEGFR1 (на СВ45+) и VEGFR2 (на CD8+, CD3+) (р &lt; 0,05 для всех). Других значимых изменений продукции ТКР не выявлено. Выявить влияние экспрессии ТКР на исход ПКР не удалось.</p></sec><sec><title>Выводы</title><p>Выводы: лимфоциты экспрессируют ТКР, их экспрессия более выражена у здоровых людей, чем у больных ПКР. После хирургического лечения наблюдается восстановление экспрессии ТКР.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: tyrosine kinases receptors (RTKs) play an important role in the pathogenesis of renal cell carcinoma (RCC). RTKs were studied on tumor and endothelial cells, but the presence of these receptors on lymphocytes was not confirmed. The objective of this study was to investigate the expression of tyrosine kinases receptors on lymphocyte subpopulations in healthy volunteers and RCC patients before and after removal of the primary tumor.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: the study included 19 patients with pT1‑T3N0 / N+M0 / M+ RCC, subjected to nephrectomy, and 10 healthy volunteers. Blood samples were collected once from healthy donors and twice from RCC patients, immediately before and 180 days after surgery. Isolation of lymphocytes and flow cytometry were carried out using standard methods. A comparative analysis of RTKs expression levels in peripheral lymphocytes from healthy volunteers and RCC patients, as well as in RCC patients before and after the operation, was carried out. A search was performed for correlations between the initial RTKs expression on lymphocytes from RCC patients and characteristics of the tumor development, as well as the disease prognosis.</p></sec><sec><title>Results</title><p>Results: VEGFR-1, -2, -3, FGFR2, PDGFRα, β RTKs are expressed on CD45+ peripheral blood mononuclear cells, as well as subpopulations of CD3+ and CD8+ lymphocytes in healthy volunteers and untreated patients with RCC. No differences in the expression levels of all studied RTKs between subpopulations of lymphocytes were found in RCC patients (p &gt; 0.05 for all). The level of RTKs expression on CD45+ peripheral cells in RCC patients before treatment is significantly lower than in healthy volunteers (p &lt; 0.05 for all). The degree of a decrease in RTKs expression correlated with the pT status and the presence of tumor-associated venous thrombosis. A significant increase in the expression levels of VEGFR1 (on CB45+) and VEGFR2 (on CD8+, CD3+) (p &lt; 0.05 for all) was noted 180 days after the removal of the primary tumor in patients with RCC. No other significant changes in RTKs production were identified. We were not able to determine the effect of RTKs expression on the RCC outcome.</p></sec><sec><title>Conclusions</title><p>Conclusions: lymphocytes express RTKs, their expression is more pronounced in healthy people than in patients with RCC. After surgical treatment, the RTKs expression becomes restored.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лимфоциты</kwd><kwd>экспрессия тирозинкиназных рецепторов</kwd><kwd>VEGFR</kwd><kwd>FGFR</kwd><kwd>PDGFR</kwd><kwd>почечно-клеточный рак</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lymphocytes</kwd><kwd>receptor of tyrosine kinase expression</kwd><kwd>VEGFR</kwd><kwd>FGFR</kwd><kwd>PDGFR</kwd><kwd>renal cell carcinoma</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке Российского научного фонда (грант № 19-15-00442)</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">Tsimafeyeu I, Zolotareva T, Varlamov S, et al.
