Glioblastoma (GBM) is the most aggressive tumor in central nervous system and contains a highly immunosuppressive microenvironment (TME). Tumor-associated macrophages microglia (TAMs) are dominant population of immune cells GBM TME that contribute to hallmarks, including immunosuppression. The understanding TAMs has been limited by lack powerful tools characterize them. However, recent progress on single-cell technologies offers an opportunity precisely at level identify new TAM subpopulations with specific tumor-modulatory functions GBM.

Abstract Glioblastoma (GBM), the predominant and primary malignant intracranial tumor, poses a formidable challenge due to its immunosuppressive microenvironment, thereby confounding conventional therapeutic interventions. Despite established treatment regimen comprising surgical intervention, radiotherapy, temozolomide administration, exploration of emerging modalities such as immunotherapy integration medicine engineering technology therapy, efficacy these approaches remains constrained, resulting in suboptimal prognostic outcomes. In recent years, intensive scrutiny inhibitory milieu within GBM has underscored significance cellular constituents microenvironment their interactions with cells neurons. Novel immune targeted therapy strategies have emerged, offering promising avenues for advancing treatment. One pivotal mechanism orchestrating immunosuppression involves aggregation myeloid-derived suppressor (MDSCs), glioma-associated macrophage/microglia (GAM), regulatory T (Tregs). Among these, MDSCs, though constituting minority (4–8%) CD45 + GBM, play central component fostering evasion propelling tumor progression, angiogenesis, invasion, metastasis. MDSCs deploy intricate mechanisms that adapt dynamic (TME). Understanding interplay between provides compelling basis This review seeks elucidate inherent explore existing targets, consolidate insights into MDSC induction contribution immunosuppression. Additionally, comprehensively surveys ongoing clinical trials potential strategies, envisioning future where targeting could reshape landscape GBM.

Here, we expand mechanism involved angiogenesis, another critical hallmark, as potential basis underlying CLOCK's pro-tumor effect GBM. Mechanistically, CLOCK-directed olfactomedin like 3 (OLFML3) expression results hypoxia-inducible factor 1-alpha (HIF1α)-mediated transcriptional upregulation periostin (POSTN). As result, secreted POSTN promotes tumor angiogenesis via activation TANK-binding kinase 1 (TBK1) signaling endothelial cells. In mouse patient-derived xenograft models, blockade POSTN-TBK1 axis inhibits progression angiogenesis. Thus, CLOCK-POSTN-TBK1 circuit coordinates key tumor-endothelial cell interaction represents an actionable therapeutic target for

Abstract Abundant macrophage infiltration and altered tumor metabolism are two key hallmarks of glioblastoma. By screening a cluster metabolic small-molecule compounds, we show that inhibiting glioblastoma cell glycolysis impairs migration lactate dehydrogenase inhibitor stiripentol emerges as the top hit.

Integrated analyses of data from transcriptome profiling, single-cell RNA sequencing, TCGA datasets, coupled with functional studies, identified legumain (LGMN) as a direct transcriptional target CLOCK–BMAL1 complex GSCs. Moreover, CLOCK-directed olfactomedin-like 3 (OLFML3) upregulates LGMN GSCs via hypoxia-inducible factor 1-alpha (HIF1α) signaling. Consequently, promotes microglial infiltration into GBM TME upregulating CD162 polarizes infiltrating microglia toward an immune-suppressive phenotype.
