Glioblastoma insights: Focus on crosstalk with the suppressive tumor microenvironment and advanced therapeutic strategies.

Glioblastoma (GBM) is an extremely aggressive brain tumor for which there is currently no curative therapy available. The tumor microenvironment comprises an intricate interplay of various cells and molecules. Recent research has increasingly emphasized the inhibitory characteristics of the microenvironment, which significantly influence tumor growth, proliferation, and response to therapy through mechanisms including immunosuppression, hypoxia, and nutritional deficits. Comprehension of the crosstalk between GBM and the suppressive tumor microenvironment has the potential to advance future investigations aimed at surmounting this inhibitory microenvironment. Additionally, it could offer guidance for the formulation of novel therapeutic approaches. Significantly, we reviewed advanced therapeutic strategies to overcome GBM, such as immune checkpoint inhibitors, chimeric antigen receptor therapies, nanoparticles, small molecule inhibitors, and stem cell-based therapies. These strategies are continuously evolving and being improved, with the potential to significantly augment the therapeutic effectiveness against GBM.
