Естественные киллеры выявлены в различных органах и тканях и могут отличаться по фенотипическим и функциональным характеристикам в зависимости от локализации. Например, естественные киллеры являются преобладающей популяцией лимфоцитов децидуальной оболочки матки на ранних сроках беременности, их доля может составлять до 70%. В матке NK-клетки могут контактировать с клетками трофобласта плода, в отношении которых также могут проявлять цитотоксичность. Естественные киллеры регулируют инвазию клеток трофобласта в матку, способствуют ремоделированию спиральных артерий и установлению физиологичного кровотока между организмами матери и плода. Обсуждается вклад нарушения функциональной активности NK-клеток в патогенез ранних репродуктивных потерь и бесплодия, вызванного иммунными факторами. Для лечения бесплодия применяют различные препараты, среди которых иммуноглобулины для внутривенного введения (ВВИГ) и рекомбинантный гранулоцитарный колониестимулирующий фактор (G-CSF). Показано увеличение вероятности имплантации эмбриона и частоты успешных вынашиваний плода у женщин, получавших терапию этими препаратами. Предполагают, что эти препараты могут оказывать влияние на фенотип и функциональную активность NK-клеток. Актуально изучение эффектов препаратов ВВИГ и G-CSF на рецепторный профиль NK-клеток. Целью настоящей работы была оценка экспрессии цитотоксических рецепторов клеток линии NK-92 в присутствии препаратов ВВИГ и рекомбинантного G-CSF. В работе использовали клетки линии NK-92 в качестве эффекторов и клетки трофобласта линии JEG-3 в качестве клеток-мишеней. Клетки культивировали совместно в присутствии одного из препаратов, а также без добавления препаратов. С помощью проточной цитометрии оценивали экспрессию клетками NK-92 рецепторов CD45, CD56, CD215, KIR2DL3, KIR2DS4, NKG2D, NKp44, NKp30. Установлено, что количество клеток линии NK-92, экспрессирующих рецепторы NKG2D, NKp30, KIR2DL3 и интенсивность экспрессии рецепторов NKG2D и NKp30, снижены в присутствии препаратов ВВИГ. В присутствии препарата G-CSF и клеток трофобласта снижено количество KIR2DL3+ и NKp44+ NK-клеток. Полученные результаты могут быть связаны как с непосредственным, так и с косвенным влиянием исследуемых препаратов на фенотип NK-клеток.</p></abstract><trans-abstract xml:lang="en"><p>Natural killer cells (NK cells) are a population of innate immune lymphocytes capable of cytolysis of infected or transformed cells without prior sensitization. Natural killers are detected in various organs and tissues and may differ in phenotypic and functional characteristics depending on localization. For example, NK cells are the dominant population (up to 70%) of decidual lymphocytes in early pregnancy. NK cells are able to contact with trophoblast cells, exert cytotoxicity towards them, as well as regulate their invasion, contributing to spiral arteries remodeling and establishment of physiological blood flow between mother and fetus. The contribution of impaired NK cell functional activity to immune mechanisms of the reproductive disorders is widely discussed. Various drugs are used to treat infertility, including intravenous immunoglobulins (IVIG) and recombinant granulocyte colony stimulating factor (G-CSF). Increased rates of embryo implantation and higher frequency of successful gestation have been shown after treatment with these drugs. The effect of these drugs on NK cells phenotype and functional activity is assumed, thus requiring further studies on the effects of IVIG and G-CSF on the receptor profile of NK cells. The aim of this work was to evaluate expression of cytotoxic receptors on the NK-92 cells in presence of IVIG and recombinant G-CSF preparations. NK-92 cells were used as effectors, and trophoblast-derived JEG-3 line served as target population. The cells were co-cultured in presence of drugs, as well as without them. Expression of CD45, CD56, CD215, KIR2DL3, KIR2DS4, NKG2D, NKp44, NKp30 receptors by NK-92 cells was evaluated by flow cytometry. The number of NK-92 cells expressing NKG2D, NKp30, KIR2DL3 receptors and the expression intensity of NKG2D and NKp30 receptors were reduced in presence of IVIG preparations. The numbers of KIR2DL3+ and NKp44+ NK cells were reduced when supplied with G-CSF and trophoblast cells. The obtained results may be associated with both direct and indirect effects of the studied drugs on the NK cell phenotype.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>NK-клетки</kwd><kwd>NK-92</kwd><kwd>трофобласт</kwd><kwd>JEG-3</kwd><kwd>иммуноглобулины для внутривенного введения</kwd><kwd>гранулоцитарный колониестимулирующий фактор</kwd><kwd>цитотоксические рецепторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>NK cells</kwd><kwd>NK-92</kwd><kwd>trophoblast</kwd><kwd>JEG-3</kwd><kwd>intravenous immunoglobulins</kwd><kwd>granulocyte colony stimulating factor</kwd><kwd>cytotoxic receptors</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This research was supported by the the Ministry of Science and Higher Education of the Russian Federation, Research Program No. 122041500061-8.</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">Arefi S., Fazeli E., Esfahani M., Borhani N., Yamini N., Hosseini A., Farifteh F.
