Сравнительная оценка субпопуляций опухолеассоциированных макрофагов при раке молочной железы в зависимости от ответа на химиотерапию

Abstract

The key cells of the immune system that determine the relationship between tumor cells and the microenvironment, beginning with early stages of tumor growth, including regulation of neoangiogenesis and the terminal stage of malignant process, are tumor-associated macrophages (TAM). In the present study, identification of TAM markers in breast tumors in patients with neoadjuvant chemotherapy and a comparative assessment of the differences in the macrophages subpopulation in tumors with different response to chemotherapy were carried out. The data we obtained indicate the functional differences between TAM subpopulations that have various phenotypes, that are confirmed at the level of associative links with the effectiveness of chemotherapy.
