В процессе эволюции антропогенный вирус натуральной оспы (Variola virus, VARV) освоил эффективные механизмы преодоления иммунологических барьеров человека, кодируя в своем геноме белки, способные взаимодействовать с рецепторами цитокинов организма-хозяина, блокируя таким образом их активность. В частности, ген G2R этого вируса кодирует белок CrmB, который эффективно связывает TNF человека и мышей. При этом данный белок является двухдоменным и наряду с TNF-связывающим N-концевым доменом содержит С-концевой хемокин-связывающий домен. При использовании методологии молекулярного клонирования нами ранее получен рекомбинантный бакулови-рус, продуцирующий в клетках насекомых рекомбинантный белок CrmB вируса натуральной оспы (VARV-CrmB), и показан его TNF-нейтрализующий потенциал в различных тестах in vitro и in vivo. С целью снижения иммуногенности этого вирусного белка при его многократном введении для терапии хронических воспалительных заболеваний получена рекомбинантная плазмида, направляющая в клетках Escherichia coli биосинтез укороченного однодоменного TNF-связывающего (TNF-BD) белка VARV. Методом металл-хелатной аффинной хроматографии из клеток выделен рекомбинантный белок TNF-BD. Терапевтический потенциал белка TNF-BD изучен в экспериментальной модели септического шока, индуцированного в организме мышей введением бактериального липополисахарида (ЛПС). После индукции септического шока животным вводили разные дозы рекомбинантного белка TNF-BD и регистрировали их гибель в течение 7 сут. Все мыши, не получавшие препарат белка TNF-BD после инъекции ЛПС, погибли через 3 сут, а в группах животных, которым вводили TNF-BD, в зависимости от дозы этого белка выжили 30, 40 или 60 % мышей. Результаты исследования демонстрируют наличие специфической фармакологической активности у рекомбинантного белка TNF-BD, синтезированного в бактериальных клетках, в мышиной модели ЛПС-индуцированного септического шока.</p></abstract><trans-abstract xml:lang="en"><p>Tumor necrosis factor (TNF) is one among the key cytokines that mediate the immune system to protect humans against viral infections. Throughout evolution, anthropogenic Variola virus (VARV) has developed effective mechanisms to overcome human defense reactions. The viral genome encodes soluble proteins imitating the structure of cellular cytokine receptors. These proteins compete with cellular receptors for cytokine binding, thus blocking the antiviral immune response. In particular, the G2R gene of VARV encodes the TNF decoy receptor, VARV-CrmB protein. This protein consists of N-ended TNF-biding (TNF-BD) and C-ended chemokine binding (Ch-BD) domains. Recombinant VARV-CrmB protein has been produced in insect cells using molecular cloning methods and its TNF neutralizing activity has been shown in vitro and in vivo. To decrease the immunogenicity of this protein, a recombinant plasmid coding for shortened TNF-BD protein of VARV in Escherichia coli cells has been constructed. Using the method of immobilized metal affinity chromatography, recombinant TNF-BD protein corresponding to the TNF-biding domain of VARV-CrmB protein was purified from E. coli cells. The therapeutic potential of TNF-BD was studied using an experimental model of LPS-induced septic shock. After septic shock induction, several doses of recombinant TNF-BD were injected and the mortality of experimental animals was observed during 7 days. All mice not injected with TNF-BD had been dead by day 3 of the experiment, but 30, 40 and 60 % of the experimental animals, who received different TNF-BD doses, survived in a dose-dependent manner. Data obtained demonstrate that recombinant TNF-BD protein is pharmacologically active in the experimental model of LPS-induced septic shock.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>белок VARV-CrmB</kwd><kwd>вирус натуральной оспы</kwd><kwd>ЛПС</kwd><kwd>септический шок</kwd><kwd>TNF-связывающий домен</kwd></kwd-group><kwd-group xml:lang="en"><kwd>VARV-CrmB protein</kwd><kwd>variola virus</kwd><kwd>LPS</kwd><kwd>septic shock</kwd><kwd>TNF-biding domain</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This work was supported by State Budgeted Project 0324-2019-0041 for ICG and the Russian Foundation for Basic Research, project 18-04-00022A.
