В настоящее время становится все более очевидным, что монотерапия с помощью любого метода лечения не является столь же эффективной, как применение комбинированной терапии. Это обуславливает появление работ, посвященных совершенствованию уже существующих методов лечения и разработке новых, среди которых онколитическая иммунотерапия является одной из наиболее стремительно развивающихся. Благодаря современным методам генетической инженерии, открываются новые возможности использования онколитических вирусов в комбинированной терапии рака, что обусловлено их способностью, помимо прямого цитодеструктивного действия, влиять как на чувствительность опухолевых клеток к терапевтическому воздействию, так и на организм в целом, обеспечивая преодоление механизмов, обеспечивающих иммунорезистентность опухоли. Данная работа посвящена получению рекомбинантного вируса осповакцины, являющегося перспективной основой для создания противопухолевых препаратов. При помощи генно-инженерных методов произведены модификации вирусного генома: в область гена, кодирующего вирусную тимидинкиназу, произведена встройка гена, кодирующего гранулоцитарно-макрофагальный колониестимулирующий фактор человека, вирусный ген A34R, кодирующий мембанный гликопротеин, заменен на ген A34R с двумя нуклеотидными заменами, приводящими к аминокислотным заменам D110N и K151E и обусловливающими увеличение доли внеклеточных оболочечных вирионов при репродукции вируса. Кроме того, были изучены свойства полученного вируса в экспериментах in vitro: показаны продукция гранулоцитарно-макрофагального колониестимулирующего фактора, отсутствие влияния проведенных модификаций вирусного генома на репродуктивные свойства вируса, усиленная способность вируса образовывать внеклеточные оболочечные вирионы.</p></abstract><trans-abstract xml:lang="en"><p>The problems of oncological disease treatment are considered relevant and timely issues of the current research programs. Since monotherapy is increasingly clear to be less effective than combination therapy, the novel studies seek for advancement of current treatments and development of new ones employing oncolytic immunotherapy being among the most rapidly evolving approaches. Modern genetic engineering techniques enable new applications of oncolytic viruses in the frames of combined cancer therapy. These applications are feasible, due to the abilities of oncolytic viruses to destruct tumor cells, like as by changing susceptibility of cancer cells to anti-tumor drug, and upon the whole body, thus overcoming the mechanisms conferring immunoresistance of tumor cells. In the present work, we have developed a recombinant vaccinia virus which is a promising platform for designing the antitumor drugs. The following modifications of viral genome were made by means of genetic engineering: gene encoding granulocyte-macrophage colony-stimulating factor was inserted into the region of viral thymidine kinase gene; viral A34R gene encoding a membrane glycoprotein, was replaced by A34R gene with two nucleotide substitutions resulting into D110N and K151E mutations which cause increased proportion of extracellular enveloped virions during the virus reproduction. Some properties of the recombinant virus were studied in vitro. The virus was shown to produce granulocyte-macrophage colony stimulating factor, and high numbers of extracellular enveloped virions. The genome modifications had no effect upon viral replication.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус осповакцины</kwd><kwd>внеклеточные оболочечные формы вируса</kwd><kwd>рак</kwd><kwd>онколитический вирус</kwd><kwd>иммунотерапия</kwd><kwd>гранулоцитарно-макрофагальный колониестимулирующий фактор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vaccinia virus</kwd><kwd>extracellular envelope form</kwd><kwd>cancer</kwd><kwd>oncolytic virus</kwd><kwd>immunotherapy</kwd><kwd>granulocyte-macrophage colony-stimulating factor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (проект № 1615-10101)</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">Autio K., Knuuttila A., Kipar A., Pesonen S., Guse K., Parviainen S., Rajamaki M., Laitinen-Vapaavuori O., Vaha-Koskela M., Kanerva A., Hemminki A.
