The tumor immune cycle regulates the normal antitumor immune response, and it’s disruption is responsible for the development of immunological tolerance. This article provides a review of russian and foreign literature published in databases such as PubMed, Medline, and Cochrane, eLibrary in the last 5 years, focusing on the emergence of immunological tolerance in breast cancer from the perspective of disrupted regulation of tumor immune cycle phases: expression of antigens on the surface of tumor cells, cancer antigen presentation, priming and activation T cells, immune infiltration of the tumor site, recognition, and elimination of tumor cells. Understanding the mechanisms underlying tumor immune cycle disruption is important for identifying new immunopathogenetic links in the development of breast cancer, as well as identifying targets to improve the effectiveness of therapy for advanced breast cancer.</p></abstract><trans-abstract xml:lang="ru"><p>Иммунологическая толерантность является одной из причин возникновения и прогрессирования злокачественных опухолей. Противоопухолевый иммунный цикл регулирует нормальный противоопухолевый иммунный ответ, а его нарушение вызывает развитие иммунологической толерантности. В статье представлен обзор отечественной и зарубежной литературы, опубликованной за последние 5 лет в базах PubMed, Medline, Cochrane, eLibrary и посвященой вопросам возникновения иммунологической толерантности при раке молочной железы с позиции нарушения регуляции фаз противоопухолевого иммунного цикла. В настоящее время выделяют следующие этапы противоопухолевого иммунного цикла: экспрессия антигенов на поверхности опухолевых клеток, созревание антигенпрезентирующих клеток и распознавание опухолевых антигенов, праймирование и активация Т-клеток, иммунная инфильтрация опухолевого очага, распознавание и уничтожение опухолевых клеток. Понимание механизмов, лежащих в основе противоопухолевого иммунного цикла, важно для выявления новых иммунопатогенетических звеньев развития рака молочной железы и таргетируемых мишеней с целью улучшения эффективности терапии распространенного рака молочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immune tolerance</kwd><kwd>breast cancer</kwd><kwd>tumor immune cycle</kwd><kwd>metabolome</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>иммунологическая толерантность</kwd><kwd>рак молочной железы</kwd><kwd>противоопухолевый иммунный цикл</kwd><kwd>метаболом</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ghorani E., Swanton C., Quezada S.A.
