Один из двух сформировавшихся ксенографтов использовали для лечения рекомбинантным вирусом осповакцины, а второй служил искусственным метастазом. В работе использовали аттенуированный рекомбинантный вирус осповакцины (ВОВ) VVdGF-GFP2, штамм Л-ИВП (GenBank accession number KP233807), с делециями двух генов вирулентности – вирусного ростового фактора и тимидинкиназы, в район которой был встроен ген зеленого флюоресцентного белка GFP2. Лечение проводили путем однократного введения внутрь опухоли рекомбинантного ВОВ в дозе 107 БОЕ/мышь. Вирус обнаруживался в клетках искусственного метастаза уже через двое суток после инфицирования, а через 8 сут достигал концентраций, сравнимых с инфицированной опухолью (~109 БОЕ/мл). Ультраструктурное исследование показало избирательное размножение рекомбинантного виру­са в опухолевых клетках. Адресное накопление GFP2 в узлах опухоли и метастаза продемонстрировано на УФО-изо­бражениях мышей, полученных с использованием In-vivo Multispectral Imaging System (Bruker, Германия). Полная деструкция ткани опухоли регистрировалась через 12 сут, а метастаза – через 20 сут после инъекции VVdGF-GFP2. В обоих случаях деструкция сопровождалась выраженным отеком и лейкоцитарной инфильтрацией ксенографтов. Рекомбинантный вирус индуцировал значимое уменьшение размеров опухоли и метастаза, к окончанию эксперимента (35-е сут) размер ксенографтов контрольных мышей в 10 раз превышал аналогичный параметр леченных (5000 против 500 мм3). Проведенное исследование показы­вает, что аттенуированный ВОВ даже при локальном периферическом способе введения не только способен разрушать ткань первичного опухолевого узла, но и обладает отчетливым антиметастатическим действием.</p></abstract><trans-abstract xml:lang="en"><p>Human carcinoma A431 cells were subcutaneously injected into nude mice at points remote from each other. One of the two xenografts developed after­wards was used for treatment with a recombinant vaccinia virus, while another served as an artificial metastasis. We used the attenuated recombinant vaccinia virus (VACV) VVdGF-GFP2 of the L-IVP strain (GenBank accession number KP233807), with deletion of two virulence genes: the virus growth factor and thymidine kinase, with the gene for the green fluorescent protein (GFP2) inserted in an area of the latter. Treatments were performed by a single intratumoral injection of the recombinant VACV at a dose of 107 PFU/mouse. VACV was detected in cells of the artificial metastasis as early as two days following infection, and after 8 days virus concentrations were com- parable with those in the infected tumor (~109 PFU/ml). Electron microscopy revealed selective replication of the recombinant in tumor cells. Targeted accumulation of GFP2 in both tumor and metastasis was shown in the UV-images of the mice obtained using the In-vivo Multispectral Imaging System (Bruker, Germany). Complete destruction of the tumor was registered after 12 days, and that of metastasis, after 20 days post injection of VVdGF-GFP2. The destruction process was accompanied by pronounced edema and leukocyte infiltration of tumor tissue. The recombinant virus induced a significant reduction in the sizes of the tumor and metastasis: by the end of the experiment (35 days) the xenografts in the control mice were 10 times larger than those in the treated mice (5000 vs. 500 mm3). Our study showed that the attenuated VACV administered by the peripheral route not only is able to destroy the primary tumor, but also has a distinct antimeta­static action.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рекомбинантный вирус осповакцины</kwd><kwd>карцинома человека А431</kwd><kwd>ксенографт</kwd><kwd>модельный метастаз</kwd><kwd>онколитическая активность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>recombinant vaccinia virus</kwd><kwd>human carcinoma A431</kwd><kwd>xenografts</kwd><kwd>metastasis model</kwd><kwd>oncolytic activity</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>РФФИ, Российский грант по государственной поддержке ведущих научных школ Российской Федерации, Минобрнауки</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">Кочнева Г.В., Бабкина И.Н., Лупан Т.А., Гражданцева А.А., Юдин П.В., Сиволобова Г.Ф., Швалов А.Н., Попов Е.Г., Бабкин И.В., Нетесов С.В., Чумаков П.М.
