Our previous work has demonstrated the efficacy of TRL-3 agonists, which include Poly(I:C) and Ridostin Pro, as part of peptide neoantigen vaccines against murine melanoma B16-F10.</p><p><bold>Aim.</bold> To evaluate the antitumor efficacy of Ridostin Pro or Poly(I:C) against murine lymphoma E.G7-OVA.</p><p><bold>Materials and methods.</bold> The study was performed on C57Bl / 6 mice with subcutaneously transplanted E.G7-OVA lymphoma containing the complete chicken ovalbumin sequence. The antitumor effects of Ridostin Pro and Poly(I:C) were evaluated in monotherapy as well as in vaccines containing chicken ovalbumin in addition to the adjuvant. The antitumor effect of Ridostin Pro and Poly(I:C) was evaluated when used in different vaccination regimens: in one case treatment was started after tumour transplantation and in the other case before tumour transplantation. The criteria of antitumor response were inhibition of tumour growth, increased survival of mice and cure.</p><p><bold>Results.</bold> Ridostin Pro and Poly(I:C) both as part of the vaccine and when administered without ovalbumin increased the percentage of tumour growth inhibition and survival of mice with E.G7-OVA lymphoma. In a regime where  vaccination with ovalbumin and Ridostin Pro or Poly(I:C) was started before tumour transfection, a complete cure of the mice was shown.</p><p><bold>Conclusion.</bold> Ridostin Pro and Poly(I:C) enhance the antitumor effect of a peptide vaccine against E.G7-OVA lymphoma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Адъювант необходим для усиления эффективности противоопухолевых пептидных вакцин. В наших предыдущих работах показана эффективность агонистов Toll-подобных рецепторов 3, к которым относятся Poly(I:C) и Ридостин Про, в составе пептидных неоантигенных вакцин против мышиной меланомы B16-F10.</p><p><bold>Цель исследования</bold> – оценить противоопухолевую эффективность адъювантов Ридостин Про и Poly(I:C) в отношении лимфомы мышей E.G7-OVA.</p><p><bold>Материалы и методы.</bold> Исследование проводили на мышах C57Bl / 6 с подкожно перевитой лимфомой E.G7-OVA, содержащей полную последовательность куриного овальбумина. Оценивали противоопухолевый эффект применения препаратов Ридостин Про и Poly(I:C) в монотерапии, а также в вакцинах, содержащих помимо адъюванта куриный овальбумин. Противоопухолевый эффект препаратов Ридостин Про и Poly(I:C) оценивали при применении в разных режимах вакцинации: в одном случае лечение начинали после перевивки опухоли, а в другом случае – до перевивки опухоли. Критериями противоопухолевого ответа служили торможение роста опухоли, увеличение продолжительности жизни и излечение мышей.</p><p><bold>Результаты.</bold> Ридостин Про и Poly(I:C) и в составе вакцины, и при введении без овальбумина увеличивали процент торможения роста опухоли и продолжительность жизни мышей с лимфомой E.G7-OVA. В режиме, когда вакцинация овальбумином с препаратом Ридостин Про или Poly(I:C) начиналась до перевивки опухоли, показано полное излечение мышей.</p><p><bold>Заключение.</bold> Ридостин Про и Poly(I:C) усиливают противоопухолевый эффект пептидной вакцины против лимфомы E.G7-OVA.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ridostin Pro</kwd><kwd> Poly(I:C)</kwd><kwd> peptide vaccine</kwd><kwd> ovalbumin</kwd><kwd> E.G7-OVA</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Ридостин Про</kwd><kwd> Poly(I:C)</kwd><kwd> пептидная вакцина</kwd><kwd> овальбумин</kwd><kwd> E.G7-OVA</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation within the framework of research work No 075-15-2021-1060 “Creation and development of a bioresource collection of genetically and phenotypically characterized human cell lines and primary tumors”.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках научно-исследовательской работы № 075-15-2021-1060 «Создание и развитие биоресурсной коллекции генетически и фенотипически охарактеризованных клеточных линий и первичных опухолей человека».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Baryshnikova M.A., Kosorukov V.S.
