The tumor microenvironment (TME) in glioblastoma (GBM) is characterized by complex interactions between tumor cells and immune components, significantly influencing disease progression and treatment outcomes. Recent studies have highlighted the presence of tertiary lymphoid structures (TLSs) in a subset of gliomas, which are associated with a remodeled perivascular space and spatial redistribution of extracellular matrix components. In a cohort of 642 gliomas, TLSs were found in 15% of tumors, suggesting a potential role in modulating immune responses (ref: Cakmak doi.org/10.1016/j.immuni.2025.09.018/). Additionally, glioblastoma has been shown to disrupt calvarial bone and alter the immune landscape of skull marrow, leading to an increased number of neutrophils and changes in B cell subsets, which may contribute to the tumor's immunosuppressive environment (ref: Dubey doi.org/10.1038/s41593-025-02064-4/). This disruption underscores the importance of understanding the TME in developing effective immunotherapies. Moreover, glioblastoma stem cells (GSCs) play a pivotal role in the tumor's immune evasion strategies. Research has identified TNFAIP6 as a key factor that promotes GSC self-renewal and reprograms pro-inflammatory macrophages into an immunosuppressive phenotype, revealing a therapeutic vulnerability in glioblastoma (ref: Chen doi.org/10.1016/j.devcel.2025.06.011/). Furthermore, the inhibition of ICAM1 has been shown to diminish GSC stemness and enhance antitumor immunity through β-catenin/PD-L1 signaling pathways (ref: Guo doi.org/10.1038/s41467-025-63796-2/). These findings collectively emphasize the intricate relationship between the TME and immune responses in glioblastoma, highlighting potential targets for therapeutic intervention.

The development of effective therapeutic strategies for glioblastoma remains a significant challenge due to its aggressive nature and the presence of an immunosuppressive microenvironment. One innovative approach involves the use of biodegradable implants that release immune-modulating small molecules to reprogram tumor-infiltrating myeloid cells towards a pro-inflammatory phenotype, thereby preventing tumor recurrence (ref: Kaiser doi.org/10.1038/s41551-025-01533-2/). This strategy addresses the critical barrier posed by myeloid cells in the TME, which often contribute to tumor progression and resistance to conventional therapies. In addition to immunomodulation, novel drug screening methodologies have been employed to identify potential therapeutic agents. A recent study utilized a comprehensive in vitro/in vivo anti-tumor drug screening approach, revealing that PKC modulators can inhibit glioblastoma progression by targeting tumor microtubes, which are essential for tumor cell communication and invasion (ref: D Azorín doi.org/10.1158/2159-8290.CD-24-0414/). Moreover, the combination of BRD4 inhibitors with radiotherapy has shown promise in sensitizing glioblastoma cells to treatment by suppressing super-enhancer-driven COL1A1, thereby enhancing therapeutic efficacy (ref: Fan doi.org/10.1038/s41388-025-03596-6/). These findings highlight the potential of combining novel drug delivery systems and targeted therapies to improve outcomes for glioblastoma patients.

Understanding the genetic and molecular landscape of glioblastoma (GBM) is crucial for developing targeted therapies. Recent research employing single-cell CUT&Tag analysis has revealed significant heterogeneity in the core regulatory circuitry of GBM, particularly highlighting the role of HOXB3 condensation as a potential therapeutic target (ref: Zhang doi.org/10.1038/s41556-025-01758-y/). This study underscores the complexity of GBM's genetic makeup and the necessity for personalized treatment approaches that consider this variability. Furthermore, integrated genomic and transcriptomic profiling of GBM has identified extrachromosomal DNA (ecDNA) as a driver of heterogeneity and microenvironmental reprogramming, with amplified oncogenes such as EGFR and MYC being localized on ecDNA (ref: Tang doi.org/10.1016/j.celrep.2025.116426/). In addition, the activation of PEAKS by the PROTAC EPIC-0726 has been shown to potentiate temozolomide efficacy in GBM through K63/K48 ubiquitination-dependent ERK/AKT suppression (ref: Hong doi.org/10.1093/neuonc/). These findings collectively highlight the importance of genetic profiling in identifying therapeutic vulnerabilities and guiding treatment strategies for GBM.

Clinical outcomes for glioblastoma (GBM) patients are influenced by various prognostic factors, including tumor genetics, treatment modalities, and patient demographics. Recent statistical reports indicate that the average annual age-adjusted incidence rate of primary malignant brain tumors is 6.86 per 100,000 population, with a significant mortality rate of 4.41 per 100,000 (ref: Price doi.org/10.1093/neuonc/). Notably, the extent of surgical resection has been shown to correlate with improved survival outcomes, particularly in younger patients, emphasizing the importance of aggressive surgical strategies in managing GBM (ref: Teske doi.org/10.1093/neuonc/). Additionally, the role of re-resection in recurrent GBM has been explored, revealing that first re-resection can provide clinical benefits, although the effectiveness may vary based on tumor type and patient age (ref: Cheng doi.org/10.1016/j.medj.2025.100891/). Furthermore, neurofluid dynamics assessed through DTI-ALPS imaging have been associated with survival in IDH wild-type GBM, suggesting that advanced imaging techniques can serve as valuable prognostic tools (ref: Hagiwara doi.org/10.1093/neuonc/). These insights into clinical outcomes and prognostic factors are essential for optimizing treatment strategies and improving patient care in GBM.

Immunotherapy, particularly checkpoint inhibition, has emerged as a promising strategy for treating glioblastoma (GBM), although challenges remain in achieving effective responses. Recent studies have demonstrated that bispecific T cell-engaging antibodies can trigger protective immune memory and remodel the glioma microenvironment in preclinical models, suggesting a potential avenue for enhancing anti-tumor immunity (ref: Zannikou doi.org/10.1136/jitc-2025-011714/). However, the efficacy of checkpoint blockade therapies in GBM has been limited, necessitating the exploration of combination strategies to overcome the immunosuppressive TME. One such strategy involves inhibiting Wnt signaling to enhance the effectiveness of checkpoint blockade in GBM. Active Wnt/β-catenin signaling has been linked to reduced T cell infiltration, indicating that targeting this pathway may improve immunotherapeutic outcomes (ref: Melssen doi.org/10.1073/pnas.2523639122/). Additionally, innovative approaches such as size-variable self-feedback nanomotors have been developed to target glioblastoma through mitochondrial mineralization, showcasing the potential of nanotechnology in enhancing immunotherapeutic efficacy (ref: Chen doi.org/10.1038/s41467-025-64020-x/). These findings highlight the need for continued research into novel immunotherapeutic strategies and their integration with existing treatment modalities.

The biology and pathophysiology of glioblastoma (GBM) are characterized by complex interactions between tumor cells and their microenvironment, significantly influencing tumor growth and treatment resistance. Chronic inflammation has been identified as a key factor shaping the TME, with studies revealing that TNFAIP6 promotes self-renewal of glioblastoma stem cells and reprograms macrophages towards an immunosuppressive phenotype, thereby facilitating tumor progression (ref: Chen doi.org/10.1016/j.devcel.2025.06.011/). This highlights the critical role of inflammatory cues in driving GBM pathophysiology. Moreover, the identification of NR4A1 as a regulator of ferroptosis in GBM has provided insights into the paradoxical roles of this gene, which can act as both an oncogene and a tumor suppressor depending on its context (ref: Tao doi.org/10.1002/acn3.70173/). Additionally, the carcinogenic role of environmental factors such as benzo[a]pyrene has been explored, revealing its potential mechanisms in GBM through integrated toxicology and transcriptomic approaches (ref: Yi doi.org/10.1016/j.ecoenv.2025.119155/). These findings underscore the multifaceted nature of GBM biology and the need for comprehensive approaches to understand its pathophysiology.

Nanotechnology has emerged as a transformative approach in the treatment of glioblastoma (GBM), particularly in enhancing drug delivery and therapeutic efficacy. Recent advancements include the development of size-variable self-feedback nanomotors that utilize the high-calcium microenvironment of glioblastoma for targeted therapy through mitochondrial mineralization (ref: Chen doi.org/10.1038/s41467-025-64020-x/). This innovative system demonstrates the potential for precise targeting of tumor cells while minimizing off-target effects. Additionally, engineered exosomes encapsulating near-infrared II (NIR-II) nanoaggregates have been developed for photothermal therapy, addressing the challenges posed by the blood-brain barrier and enhancing therapeutic outcomes in GBM (ref: Bai doi.org/10.1021/acs.analchem.5c05448/). Furthermore, the integration of NIR-II fluorescence imaging with piezodynamic therapy has shown promise in improving the efficacy of cancer theranostics, indicating a significant advancement in non-invasive treatment modalities (ref: Ullah doi.org/10.1002/smll.202510697/). These developments highlight the potential of nanotechnology in revolutionizing treatment strategies for glioblastoma.

Radiotherapy remains a cornerstone in the treatment of glioblastoma (GBM), yet treatment resistance poses a significant challenge. Recent studies have explored various strategies to enhance the efficacy of radiotherapy, including the use of BRD4 inhibitors, which sensitize GBM cells to radiation by suppressing super-enhancer-driven COL1A1, thereby prolonging survival in preclinical models (ref: Fan doi.org/10.1038/s41388-025-03596-6/). This approach highlights the potential for combining targeted therapies with radiotherapy to overcome resistance mechanisms. Moreover, the role of environmental carcinogens, such as benzo[a]pyrene, has been investigated to understand their contribution to GBM pathogenesis and treatment resistance. By employing network toxicology and single-cell transcriptomics, researchers have begun to elucidate the molecular mechanisms underlying GBM's response to environmental factors (ref: Yi doi.org/10.1016/j.ecoenv.2025.119155/). Additionally, the application of Tumor Treating Fields (TTFields) in combination with stereotactic radiosurgery has demonstrated efficacy in prolonging time to intracranial progression in patients with brain metastases, indicating a potential strategy for enhancing radiotherapy outcomes (ref: Mehta doi.org/10.1016/j.ijrobp.2025.08.066/). These findings underscore the importance of addressing treatment resistance in glioblastoma through innovative therapeutic strategies.
