Glioblastoma (GBM) has been an aggressive brain tumor and it demonstrates poor prognosis and resistance to the traditional therapeutics. GBM is characterized by abnormal proliferation, high growth, and a significantly immunosuppressive tumor microenvironment (TME), making immunotherapy as an ideal treatment for GBM. The recent advances in the field of immunotherapy such as vaccines, and CAR-T cell treatments, have demonstrated significant efficacy in accelerating anticancer immune responses and improving survival outcomes. Immune checkpoint drugs targeting CTLA-4 and PD-1/PD-L1 have demonstrated synergistic effects in enhancing T cell activation and infiltration. Vaccines such as DCVax-L and oncolytic viruses including G47 have demonstrated promising outcomes in the clinical studies. CAR-T cell treatments have been directed against particular antigens such as EGFRvIII and IL13R 2 and have demonstrated considerable antitumor efficacy. Nonetheless, there are a number of challenges to be considered including the immunosuppressive TME, the blood-brain barrier (BBB), and the molecular heterogeneity of GBM. Addressing these challenges requires a versatile strategy, encompassing the development of innovative combination drugs, complicated imaging methodologies to evaluate treatment efficacy, and the discovery of biomarkers to predict patient responses to immunotherapy. The future research can focus on highlighting the complicated connections between the immune system and GBM, utilizing perspectives from preclinical models and clinical studies to formulate more effective and customized treatment options. This review emphasizes on the recent research results and clinical data, providing insights into prospective developments in GBM immunotherapy and highlighting the necessity of a comprehensive strategy to enhance patient outcomes.
