Несмотря на достигнутые успехи в диагностике РМЖ и новейшие лекарственные режимы лечения, остается еще целый ряд нерешенных задач, связанных с  развитием опухолевой резистентности и, как следствие, прогрессированием заболевания. Одним из факторов, определяющих устойчивость опухоли к современным методам лечения, является ее способность уклоняться от иммунного ответа. Поэтому на сегодняшний день учеными всего мира достаточно много внимания уделяется изучению механизмов взаимодействия опухоли с иммунной системой организма.</p><p>Известно, что микроокружение опухоли вносит значительный вклад в формирование характера данного взаимодействия. Частью микроокружения опухоли являются иммунные клетки, которые могут быть опухольассоциированными макрофагами, супрессорными клетками миелоидного происхождения, опухоль-инфильтрирующими лимфоцитами. Лимфоциты, инфильтрирующие опухоль, представлены В-, Т-, NK-клетками, локализация которых и их субпопуляционный состав в опухоли могут иметь разное прогностическое и клиническое значение. Плотность инфильтрации отдельными видами эффекторных клеток до химиотерапии служит важным предиктором выживаемости больных. Иными словами, присутствие субпопуляций эффекторных лимфоцитов в опухоли характеризует степень напряженности противоопухолевого иммунного ответа и может определять успешность лекарственного лечения.</p><p>В данном исследовании проанализированы уровни инфильтрации CD3, CD4, CD20, СD38  лимфоцитами при нескольких молекулярных подтипах РМЖ. Иммунофенотипирование опухоли проведено на криостатных срезах методом иммунофлуоресценции (микроскоп Zeiss (Axioskop, Германия)). Проанализированы 96  образцов люминального РМЖ (37 (38,5  %)  — подтип А; 52 (54,2  %)  — В-Her2-негативный подтип; 7 (7,3  %)  — В-Her2-позитивный подтип) и нелюминального РМЖ (3 (14,3 %) — HER2+ подтип; 18 (85,7 %) — трижды негативный подтип). Оценивались характер инфильтрации и выраженность экспрессии антигенов. Анализ уровня инфильтрации субпопуляциями лимфоцитов установил, что при люминальном РМЖ выраженность инфильтрации меньше, чем при других подтипах, однако достоверной связи не обнаружено.</p></abstract><trans-abstract xml:lang="en"><p>Breast cancer (BC) is most prevalent female malignancy worldwide. Despite advances in BC diagnosis and progress in drug therapy, a series of challenges associated with emergent tumour resistance causing the disease escalation still remain. Immune evasion is among the driving forces of tumour resistance against modern treatments, which promotes world-active research into the mechanisms of tumour—immune interaction.</p><p>Tumour microenvironment is known to contribute greatly to the nature of this interaction. Immune cells are constitutive of tumour microenvironment as tumour-associated macrophages, myeloid-derived suppressor cells and tumour-infi ltrating lymphocytes. Tumour-infi ltrating lymphocytes are represented by B-, T- and NK-cells, which localisation and subpopulation structure in tumour may possess a prognostic and clinical significance. Th e infi ltration density by certain effector cell types prior to chemotherapy is an important predictor of patient survival. Putting otherwise, the presence of effector lymphocyte subpopulations in tumour defi nes the strength of antitumour immunity and may establish the success of drug treatment.</p><p>This study analysed the infiltration levels of CD3, CD4, CD20 and CD38 lymphocytes in several molecular BC subtypes. Tumour immunophenotyping was performed in cryosectioning and immunofl uorescence assays with a ZEISS AXIOSKOP microscope, Germany. We analysed 96 luminal BC (37 subtype A (38.5 %), 52 B-Her2-negative subtype (54.2 %), 7 B-Her2-positive subtype (7.3 %)) and non-luminal BC samples (3 HER2+ subtype (14.3 %), 18 triple-negative subtype (85.7 %)). The infiltration and antigen expression patterns have been assessed. Analyses of tumour-infi ltrating subpopulations revealed lower infiltration in luminal BC vs. other subtypes, albeit at no significance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>молекулярные подтипы</kwd><kwd>опухоль-инфильтрирующие лимфоциты</kwd><kwd>эффекторные лимфоциты</kwd><kwd>иммунофлюоресцентный анализ</kwd><kwd>иммунофенотипирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>molecular subtypes</kwd><kwd>tumour-infi ltrating lymphocytes</kwd><kwd>eff ector lymphocytes</kwd><kwd>immunofl uorescent assay</kwd><kwd>immunophenotyping</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">Ferlay J., Colombet M., Soerjomataram I., Parkin D.M., Piñeros M., Znaor A., et al.
