The progress of immune escape-related molecule B7-H1 on malignant tumors with multidrug resistance / 医学研究生学报

Malignant tumors with multidrug resistance is one of the major reasons for the failure of tumor treatment, and it is also an important issue in the field of cancer treatment. In recent years, with the continuous research on tumor immune microenvironment, the status of tumor immune escape is deeply understood. The close relationship between the abnormal expression of related molecules B7-H1 and tumor resistance is constantly recognized that multidrug resistant tumor may be more sensitive to immune system surveillance and killing than chemotherapy-sensitive tumor. The article reviews the progress of immune escape-related molecule B7-H1 in multidrug resistance of malignant tumors.
