Этих изменений недостаточно для того, чтобы иммунная система распознала и уничтожила мутировавшие клетки. Причина этого явления - слабая иммуногенность опухолево-ассоциированных антигенов (ТАА) .Противоопухолевая вакцинация является наиболее эффективным специфическим методом  как профилактики рецидива заболевания , так и терапевтическим инструментом лечения в онкологии. Одним из главных условий эффективности противоопухолевой иммунотерапии является повышение иммуногенности  опухолевых клеток. Иммунизация моно - или олиго-ТАА-производными пептидами  не обеспечивает общее подавление развития опухоли и даже создает благоприятные условия для селективного роста отдельных клонов опухолевых клеток, не имеющих общих АГ с вакцинальными клетками.  Ксеногенные АГ обладают высокой иммуногенностью и эффективны в разрушении иммунной толерантности к человеческим аналогам, представленным на опухолевых клетках. В нашей работе мы использовали тестикулярные АГ барана в качестве источника ксеногенных ТАА. Яички овец содержат большой набор ТАА. Экспериментальные мыши были иммунизированы липосомальной тестикулярной вакциной, полученной из яичек барана. Через месяц после вакцинации мышам подкожно имплантировали опухолевые клетки карциномы LLC. Обнаружено, что продолжительность жизни мышей опытной группы была в 2 раза выше по сравнению с сингенным контролем, при этом, у 20% из них опухоль не развилась вообще. В спленоцитах мышей , у которых не было опухолей , определяли Т-регуляторные клетки и Т-клетки памяти. Мы обнаружили достоверное снижение как наивных Т-регуляторных ( CD4+CD25+) , так и активированных (CD4+CD25+FoxP3+), а также Т-памяти( CD4+CD44+), в том числе популяцию центральных Т- памяти (CD4+CD44+CD62L+) в селезенке предварительно иммунизированных мышей по сравнению с лимфоцитами мышей, полученных из интактной селезенки. Исследование содержания ИФН-гамма и ИЛ-10 в супернатантах мышиных спленоцитов , полученных от вакцинированных мышей без опухолей показало достоверное снижение количества ИЛ-10, но не ИФН-гамма. На основании полученных результатов мы полагаем, что иммунизация ксеногенными опухолевыми АГ может привести к формированию эффективного противоопухолевого ответа, направленного на опухолеассоциированные АГ, имеющиеся на собственной опухоли.</p></abstract><trans-abstract xml:lang="en"><p>Аppearance of a malignant tumor is associated with impaired mechanisms of proliferation, differentiation, apoptosis ability. However, these changes are not enough for immune system to recognize and destroy mutated cells. Weak immunogenicity of tumor-associated antigens (TAA) and the insufficiency of co-stimulating molecules on the surface of tumor cells is a reason for this phenomenon Since biochemical processes of tumor cells and healthy tissue cells are identical, therefore creation of effective chemotherapeutic drugs is limited not by selectivity of their action. So antitumor vaccination is the most effective specific method for both preventing recurrence of a disease and a therapeutic treatment tool in oncology. Xenogeneic proteins are highly immunogenic and effective in breaking immune tolerance to human analogs. In our work, we used sheep testicular AG as a source xenogenic TAAs. Sheep testicles contain a large set of TAAs. Experimental mice were immunized with type liposomal testicular vaccine from sheep, one month after vaccination, to induce tumor growth, cells of carcinoma LLC were implanted in mouse. The life expectancy of the experimental group of mice was 2 times higher compared to the syngenetic control and 20% of them did not develop the tumor at all. In the spleen of mice who did not have tumors after pre-vaccination sheep liposomal testicular AG, T-regulatory cells and T-memory cells were measured. We found a credible decrease in both naive Treg (CD4+CD25+), activated (CD4+CD25+FoxP3+) and both T-memory (CD4+CD44+) and central memory (CD4+CD44+CD62L+) in spleen pre-vaccination mice with compared to the contral intact spleen. Content of IFNg and IL-10 in supernatants of mouse slenocytes derived from vaccinated mice with no tumors was investigated and showed a reliable decrease in the amount of IL-10, but not IFNg. We believe that immunization with xenogenic tumor AGs can lead to the formation of a protective antitumor response. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Противопухолевые вакцины</kwd><kwd>карцинома легких Льюиса (LLC)</kwd><kwd>опухолеспецифические антигены</kwd><kwd>тестикулярные антигены</kwd><kwd>иммунотерапия</kwd><kwd>иммунный ответ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cancer vaccines</kwd><kwd>Lewis lung carcinoma (LLC)</kwd><kwd>tumor-specific antigens</kwd><kwd>testis antigens</kwd><kwd>immunotherapy</kwd><kwd>immune response</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bode P.K., Thielken A., Brandt S. et al.
