Advances in research on immune escape mechanism of glioma

Abstract

AbstractBackgroundGlioma is the most common primary intracranial malignancy in clinical practice, and in particular, IDH‐wildtype glioblastoma has the worst prognosis. In recent years, surgical resection combined with simultaneous radiotherapy and immune checkpoint inhibitors has made some progress, but the efficacy is still not satisfactory, which may be related to the low immunogenicity of glioma cells and the tumor immunosuppressive microenvironment.MethodsA comprehensive review of relevant literature was conducted to explore the mechanisms by which tumors suppress antitumor immune responses and produce escape, with a focus on the immune cells in the tumor microenvironment (TME).ResultsThe mechanisms involved in immune evasion of glioma cells are complex and involve with immune cell differentiation and function.ConclusionOur review emphasizes the need for a more profound comprehension of the mechanisms involved in immune response and immune evasion in glioma, to formulate more efficacious treatment modalities.
