The tumor microenvironment (TME) plays a critical role in glioblastoma (GBM) progression and immune evasion. Recent studies have shown that microglia, the brain's resident immune cells, are mobilized ahead of GBM invasion, forming structures known as 'oncostreams' that facilitate collective tumor cell migration (ref: Kang doi.org/10.1038/s43018-025-00985-4/). This interaction between GBM cells and tumor-associated macrophages (TAMs) is further complicated by the presence of glioblastoma-enriched glycosphingolipids, which modulate the function of invariant natural killer T (iNKT) cells, contributing to the immunosuppressive environment characteristic of GBM (ref: Coombs doi.org/10.1093/neuonc/). Additionally, glioma-neuronal circuit remodeling has been shown to induce regional immunosuppression, with areas of enhanced neuronal connectivity exhibiting distinct immune cell compositions, including an increase in anti-inflammatory TAMs (ref: Nejo doi.org/10.1038/s41467-025-60074-z/). These findings highlight the intricate interplay between tumor cells and the immune landscape, suggesting that targeting these interactions may enhance therapeutic efficacy. Moreover, innovative approaches such as the development of a nose-to-brain delivery system for nano-vaccines aim to circumvent the blood-brain barrier and improve glioblastoma immunotherapy (ref: Wang doi.org/10.1021/acsnano.5c06051/). The role of gabapentinoids in providing survival benefits in GBM patients has also been explored, emphasizing the importance of neuronal interactions in tumor progression (ref: Bernstock doi.org/10.1038/s41467-025-59614-4/). Furthermore, the stabilization of SOX9 by USP18 has been identified as a mechanism promoting glioblastoma stemness and malignant progression, underscoring the potential for targeting these pathways in future therapies (ref: Liu doi.org/10.1038/s41420-025-02522-9/).
