ABSTRACT
@#Myeloid-derived suppressor cells (MDSCs) are a group of highly heterogeneous immunosuppressive cells produced in the bone marrow, which accumulate in large amounts under pathological conditions such as malignant tumors. MDSCs are the significant cell subsets that reduce patients' response to traditional treatment and promote tumor progression. In recent years, immune checkpoint blockade and adoptive transfusion of engineered T cells have significantly prolonged the survival of many patients with advanced malignant tumors, but the effective rate from 15% to 40% in some solid tumors including lung cancer, colorectal cancer etc., which is closely related to the immunosuppressive microenvironment in solid cancers. With the accumulation in tumor microenvironment, MDSCs reduce the anti-tumor immune response of patients by inhibiting T cell or NK cell proliferation and function, which is the key mechanism for patients tolerating to immunotherapy. Therefore, clarifying the accumulation and functional characteristics of MDSCs is an important research direction to explore the improvement of restoring immunotherapy. This article will systematically elaborate the regulatory mechanism of MDSC production, aggregation and immunosuppressive function, and outline the latest research progress of targeted MDSC therapy
