Myeloid-derived suppressor cells (MDSCs) are a subgroup of immunosuppressive heterogeneous cells derived from bone marrow (BM) stem cells. They not only strongly inhibit T cell-mediated antitumor immune response but also directly induce tumorigenesis and promote tumor growth and metastasis. Besides, the nonresolving inflammation (NRI), a prime cause of tumor development, is present in the glioma microenvironment. However, the relationship between MDSCs and NRI, especially in the view of relevant molecular regulatory networks, has not been fully elucidated in gliomas. In the present study, the MDSC- and NRI-associated molecular regulatory network and key regulatory points are reviewed, and the targeted therapeutic strategies against gliomas are further discussed.
