Research on the Safety and Efficacy of Blocking Dural Blood Supply in Glioblastoma Patients

Glioblastoma is the most common primary malignancy of the central nervous system with a very poor prognosis. Most of the immunotherapies that have made significant breakthroughs in the treatment of other tumors in recent years are unsatisfactory in the application of glioblastoma, which is mainly inseparable from the highly inhibitory immune microenvironment formed by the latter. Therefore, how to change this "immune desert" and better activate immune effector cells to play an anti-tumor effect is currently a hot spot in glioma immune research. In recent years, there has been continuous research support that the myeloid cells of the central nervous system are partly derived from the bone marrow of the skull, and there is a special channel connection between the skull and the dura mater, through which immune cells can be transported. This suggests that some of the tumor-associated macroph
