Одним из часто используемых методов трансфекции в работе с дендритными клетками, является электропорация. Суть метода состоит в повышении проницаемости мембраны путем проведения электрического импульса через клетку. В связи с повышенной проницаемостью мембраны повышается шанс попадания ДНК или РНК конструкций внутрь клетки, но при этом снижается выживаемость клетки после воздействия тока на плазматическую мембрану клетки.</p><p>В исследовании использовали мышей самцов линии C57Bl/6 возраста 2-4 месяца. Из бедренной кости мышей выделяли 20 × 106 клеток костного мозга, после клетки культивировали в полной RPMI1640 среды в течение 7 суток. Для генерации дендритных клеток из клеток костного мозга, в культуральную среду добавляли 100 нг/мл rmFlt3-L на 0 день. После 7 дней культивирования, клеточную культуру электропорировали контрольными некодирующими плазмидами p5 (EP P5) или пламзмидами pmaxCCR9 (EP CCR9), кодирующими мышиный рецептор хемотаксиса CCR9. В качестве контролей выступали, клеточные культуры электропорированные без плазмид (mock EP) и культуры клеток без электропорации (none EP). Электропорировали 5 × 105 клеток и оставляли на 10 минут. После 10 минут клетки собирались и рассаживались в 24-луночном планшете в 1 мл культуральной среды и кондиционной среды (1:1). Затем добавляли по 50 нг/мл Flt3-L в каждую лунку. На следующий день трансфицированные клетки оценивались с помощью метода проточной цитофлуориметрии и количественной ПЦР.</p><p>Установлено, что после электропорации в группах mock EP, EP P5, EP CCR9 относительное количество живых CD11c+ дендритных клеток было достоверно меньше, чем в non EP группе. Более того, в группах EP P5 и EP CCR9 было достоверно меньше живых CD11c+ дендритных клеток, чем в группе mock EP. Экспрессия маркера CD86 было достоверно выше в группах EP P5 и EP CCR9, чем в группах non EP и mock EP. Экспрессия I-Ab среди cDC2s было достоверно выше в группе EP CCR9 по сравнению с группой non EP. У плазмацитоидных дендритных клеток и конвенциональных дендритных клеток 2-го типа, в группах EP CCR9, экспрессия CCR9 была достоверно выше, чем в группе non EP.</p><p>Таким образом, в данном исследовании продемонстрирована эффективность электропорации, сопровождающаяся снижением выживаемости и созреванием дендритных клеток. </p></abstract><trans-abstract xml:lang="en"><p>Today transfection of mammalian cell with DNA or RNA construction is the only method for delivering programmed information into the cell nucleus. Electroporation is most commonly used method of transfection in experiments with dendritic cell. The aim of electroporation is to permeabilize the membrane by passing electric impulse through the cell. Due to the increase permeability of the membrane chance DNA or RNA construction getting inside into the cell is increased, wherein survival of the cells is decreased.</p><p>In the study male mice C57Bl/6 line 2-4 months old were used. From femur bones was isolated 20 × 106 bone marrow cells, which were cultured in 20 mL of complete RPMI-1640 for 7 days. To generate dendritic cells from BM cells, 100 ng/mL of rmFlt3-L was added to culture media at day 0. After 7 days of cultivation, the cell cultures were electroporated with control noncoding plasmids p5 (EP P5) or pmaxCCR9 encoding mouse chemokine receptor CCR9 (EP CCR9). The controls were cell cultures electroporated without any plasmids (mock EP) and cell cultures without electroporation (none EP). 5 × 105 cells were electroporated and resting for 10 minutes. After 10 minutes, cells were harvested and seeded into 24-well plates in 1 mL of culture medium and conditioning medium (1:1). Then, 50 ng/mL of Flt3-L was added to each well. The next day, transfected cells were collected and used for flow cytometry, qRT-PCR analysis.</p><p>It was found that after electroporation in the groups mock EP, EP P5, EP CCR9 relative amount of live CD11c+ dendritic cells was significantly less than in the non EP group. Moreover, in the EP P5 and EP CCR9 groups the frequency of live CD11c+ dendritic cells was significantly less than in the mock EP group. Expression of the CD86 marker in the EP P5 and EP CCR9 groups was significantly higher than in the non EP and mock EP groups. Expression of the I-AB(MHCII) in the EP CCR9 group on cDC2s was significantly higher than in the non EP group. On plasmacytoid DCs (pDCs) and conventional type 2 DCs (cDC2s) in the EP CCR9 group expression of CCR9 was significantly higher than in the non EP group. Therefore, in this study, we demonstrated the effectiveness of electroporation, accompanied by the decrease in the survival rate and maturation of DCs. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>электропорация</kwd><kwd>плазмацитоидные дендритные клетки</kwd><kwd>конвенциональные дендритные клетки 2-го типа</kwd><kwd>ДНК конструкции</kwd><kwd>жизнеспособность</kwd><kwd>зрелость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electroporation</kwd><kwd>plasmacytoid dendritic cells</kwd><kwd>conventional dendritic cell type 2</kwd><kwd>DNA constructions</kwd><kwd>viability</kwd><kwd>maturity</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was supported by the Russian Science Foundation (Agreement No. 16-15-00086).</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">Baravalle G., Park H., McSweeney M., Ohmura-Hoshino M., Matsuki Y., Ishido S., Shin J.-S.
