К числу таких соединений относятся проникающие в клетки пептиды (Cell-Penetrating Peptides), которые легко транслоцируются через мембраны эукариотических клеток и могут служить переносчиками разнообразных терапевтических агентов в клетки. Целью данной работы явилось изучение способности антимикробного пептида системы врожденного иммунитета – аципенсина 1 – проникать в опухолевые клетки человека in vitro. Аципенсин 1 – катионный пептид, выделенный нами ранее из лейкоцитов русского осетра Acipenser gueldenstaedtii. В рамках данного исследования впервые установлено, что аципенсин 1 может проникать в эукариотические клетки без их повреждения. Разработана процедура получения рекомбинантного препарата аципенсина 1, проведена конъюгация пептида с флуоресцентным маркером BODIPY FL. С использованием конфокальной микроскопии показано, что меченый аципенсин 1 быстро транслоцируется в клетки эритромиелоидного лейкоза человека линии К-562 и детектируется во внутриклеточном пространстве уже чрез 5 мин после добавления его в культуру клеток. С помощью проточной цитометрии изучена кинетика проникновения меченых пептидов (в нетоксических микромолярных концентрациях) в клетки К-562, получены данные о быстрой интернализации меченого пептида в исследуемые клетки, подтверждающие результаты микроскопического анализа: несущий флуоресцентную метку пептид выявлялся в клетках К-562 через 2-3 секунды после внесения препарата инкубационную среду, максимум флуоресценции достигался на сроке около 45 секунд, с дальнейшим выходом «на плато» на сроках свыше 100 секунд после стимуляции клеток исследуемым соединением. Установленные факты подтверждают концепцию о том, что антимикробные пептиды врожденного иммунитета обладают свойствами проникающих в клетки пептидов, а также позволяют рассматривать исследуемый антимикробный пептид аципенсин 1 как перспективное соединение, на основе которого могут быть разработаны новые лекарственные препараты с повышенной способностью проникать в клетки-мишени, участвующие в патологических процессах и, следовательно, с более высокой эффективностью терапевтического действия. </p></abstract><trans-abstract xml:lang="en"><p>Search for new compounds providing delivery of drugs into infected or neoplastic cells, is an important direction of biomedical research. Cell-penetrating peptides are among those compounds, due to their ability to translocate through membranes of eukaryotic cells, serving as potential carriers of various therapeutic agents to the target cells. The aim of present work was to investigate the ability of acipensin 1, an antimicrobial peptide of innate immune system, for in vitro penetration into human tumor cells. Acipensin 1 is a cationic peptide that we have previously isolated from leukocytes of the Russian sturgeon, Acipenser gueldenstaedtii. Capability of acipensin 1 to enter the human erytroleukemia K-562 cells has been investigated for the first time. A biotechnological procedure for producing a recombinant acipensin 1 peptide has been developed. The obtained peptide was conjugated with a fluorescent probe BODIPY FL. By means of confocal microscopy, we have shown that the tagged acipensin 1 rapidly enters into K-562 cells and can be detected in the intracellular space within 5 min after its addition to the cell culture. Using flow cytometry technique, penetration kinetics of the labeled peptide into K-562 cells (at nontoxic micromolar concentrations) has been studied. We have observed a rapid internalization of the peptide to the target cells, thus confirming the results of microscopic analysis, i.e, the labeled acipensin was detectable in K-562 cells as soon as wihin 2-3 seconds after its addition to the incubation medium. The maximum of fluorescence was reached within a period of approx. 45 seconds, with further “plateau” at the terms of &gt;100 seconds following cell stimulation with the test compound. These data support the concept, that the antimicrobial peptides of innate immunity system possess the features of cell-penetrating peptides, and allow us to consider the studied sturgeon peptide a promising template for development of new drugs with increased ability to enter the cells implicated into pathological processes, and, therefore, higher therapeutic efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>проникающие в клетки пептиды</kwd><kwd>антимикробные пептиды</kwd><kwd>аципенсин 1</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cell-penetrating peptides</kwd><kwd>antimicrobial peptides</kwd><kwd>acipensin 1</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шамова О.В., Сакута Г.А., Орлов Д.С., Зенин В.В., Штейн Г.И., Колодкин Н.И., Афонина И.Н., Кокряков В.Н.
