Вместе с тем, NET играют важную роль в патогенезе многих аутоиммунных и воспалительных заболеваний, а также злокачественных новообразований. Кролики являются одним из наиболее часто используемых видов лабораторных животных в медицинских и биологических исследованиях. На кроликах разработано большое количество моделей различных заболеваний сердечно-сосудистой, иммунной и других систем человека. Однако в научной литературе отсутствуют сведения о способности нейтрофилов кролика подвергаться NETозу (программируемой гибели клеток в процессе образования NET) в ответ на известные фармакологические стимулы. Целью представленной работы было изучение в системе in vitro способности нейтрофилов кролика породы Советская шиншилла образовывать NET в ответ на миметик диацилглицерола форбол-12-миристат-13-ацетат (ФМА) и кальциевый ионофор А23187. Для выделения нейтрофилов кролика использовали метод центрифугирования в одноступенчатом градиенте плотности Ficoll-Hypaque с модификациями. Окислительный взрыв оценивали методом регистрации люминол-зависимой хемилюминесценции, а образование NET – с помощью иммунофлуоресцентного анализа. В работе впервые показано, что нейтрофилы кролика Советская шиншилла не образуют NET в ответ на ФМА, но формируют ловушки в ответ на А23187, а также обладают низким уровнем окислительного взрыва в ответ на ФМА, А23187 и хемоаттрактант N-формил-метионил-лейцил-фенилаланин.</p></abstract><trans-abstract xml:lang="en"><p>Neutrophil extracellular traps (NETs) are decondensed nuclear chromatin, decorated with bactericidal proteins of various cell organelles and performing an effector function aimed to combat pathogens at the site of inflammation. At the same time, NETs play an important role in the pathogenesis of many autoimmune and inflammatory diseases as well as malignancies. Rabbits are one of the most commonly used species of laboratory animals in medical and biological research. A large number of models of various diseases of the cardiovascular, immune and other human systems have been developed in rabbits. However, there is no information in the scientific literature about the ability of rabbit neutrophils to undergo NETosis in response to well-known pharmacological stimuli. The purpose of the present work was to study in in vitro system the ability of neutrophils of Soviet chinchilla rabbit to form NETs in response to mimetic of diacylglycerol phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187. To isolate rabbit neutrophils, the one-step density gradient centrifugation on Ficoll-Hypaque method with modifications was used. Oxidative burst was assessed with luminol-amplified chemiluminescence method, and NET formation was assessed with immunofluorescence analysis. The work shows for the first time that neutrophils of Soviet chinchilla rabbit do not form NETs in response to PMA, but form traps in response to A23187, as well as have a low level of oxidative burst in response to PMA, A23187 and chemoattractant N-formyl-methionylleucyl- phenylalanine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нейтрофилы кролика</kwd><kwd>нейтрофильные внеклеточные ловушки</kwd><kwd>NET</kwd><kwd>окислительный взрыв</kwd><kwd>форбол-12-миристат-13-ацетат</kwd><kwd>А23187</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rabbit neutrophils</kwd><kwd>neutrophil extracellular traps</kwd><kwd>NETs</kwd><kwd>oxidative burst</kwd><kwd>phorbol 12-myristate 13-acetate</kwd><kwd>A23187</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта «Молекулярные и клеточные основы иммунитета» (проект 21-1-21, номер ЦИТИС 121042600047-9).</funding-statement><funding-statement xml:lang="en">The research was carried out within the framework of the Scientific Project of the State Order of the Government of Russian Federation to Lomonosov Moscow State University (project No. 121042600047-9) and Interdisciplinary Scientific and Educational School of Lomonosov Moscow State University “Molecular Technologies of the Living Systems and Synthetic Biology.”</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">Brinkmann V., Reichard U., Goosmann C., Fauler B., Uhlemann Y., Weiss D.S., Weinrauch Y., Zychlinsky A.
