The tumor microenvironment (TME) in glioblastoma (GBM) is characterized by complex interactions between tumor cells and immune components, significantly influencing tumor progression and treatment response. Recent studies have identified distinct populations of tumor-associated macrophages (TAMs) that play critical roles in modulating the immune landscape. For instance, Wang et al. utilized single-cell transcriptomics to uncover a hypoxic subset of monocyte-derived TAMs that are localized to the peri-necrotic niche, suggesting their potential for therapeutic targeting to normalize tumor vasculature (ref: Wang doi.org/10.1016/j.ccell.2024.03.013/). Furthermore, Yabo et al. demonstrated that GBM-instructed microglia transition to heterogeneous phenotypic states, which are crucial for supporting tumor growth and altering immune cell interactions, particularly following temozolomide treatment (ref: Yabo doi.org/10.1186/s13073-024-01321-8/). This highlights the dynamic nature of the TME and its impact on treatment efficacy. In addition to macrophage dynamics, the role of galectin-3 in shaping the TME has been emphasized by Rivera-Ramos et al., who found that galectin-3 depletion can restrain cancer cell growth by taming pro-tumoral microglia (ref: Rivera-Ramos doi.org/10.1016/j.canlet.2024.216879/). The interplay between glioblastoma stem cells (GSCs) and TAMs is further underscored by Li et al., who identified IFI35 as a key regulator of non-canonical NF-κB signaling that maintains GSCs and recruits TAMs, thereby contributing to the immunosuppressive TME (ref: Li doi.org/10.1038/s41418-024-01292-8/). Collectively, these findings underscore the importance of targeting the TME and its cellular components to enhance therapeutic outcomes in GBM.
