WebMay 8, 2024 · GBM is one of the most malignant brain tumours. Although patients receive active treatment, the 5-year survival rate is less than 5 %. GBM is characterized by a lack of T cell infiltration but abundant tumour-associated macrophage (TAM) infiltration [].M2 TAMs are the main TAMs in most malignant tumours and play important roles in … WebFeb 8, 2024 · Spatiotemporal regulation of tumor immunity remains largely unexplored. Here we identify a vascular niche that controls alternative macrophage activation in glioblastoma (GBM). We show that tumor-promoting macrophages are spatially proximate to GBM-associated endothelial cells (ECs), permissive for angiocrine-induced …
Tumor progression is independent of tumor-associated macrophages …
WebFeb 4, 2024 · The fact that modulating the macrophage compartment is indeed a promising approach was shown a couple of years ago by the administration of a brain penetrating CSF1R inhibitor in mice, which repolarized TAM into a more anti-tumoral phenotype resulting in a reduced GBM progression (Pyonteck et al., 2013). WebMar 25, 2024 · In human GBM, microglia and macrophages more resemble the expression profile of non-polarized M0 macrophages .

WebJul 27, 2024 · Glioblastoma (GBM) is the most common and malignant primary brain tumor in adults. Currently, the standard treatment of glioblastoma includes surgery, … WebMar 7, 2024 · Schematic representation of GBM-EVs effects on the myeloid immune cells mediated by transfer of the cargo molecules (mostly RNAs). GBM-EVs (on the top) fuse with or get phagocytosed by macrophages, myeloid-derived suppressor cells (MDSC) and dendritic cells (DC) causing changes in phenotype of recipient cells. To understand the heterogeneity of cellular profiles in GBM, we collected single-cell RNA-seq data from nine GBM cases and combined it with 41 GBM cases from previously published studies for a total of 79,968 single-cell transcriptomes (Additional file 1: Table S1). To reduce the batch effect, we filtered … See more We next investigated whether this macrophage subpopulation could also be observed in lower-grade gliomas (LGGs), which include grade … See more To determine if the anti-inflammatory properties of MARCO+ macrophages play a role in PD1 checkpoint inhibitor therapies, we … See more To uncover the source of this mesenchymal signature, we went back to our single-cell expression data. The mesenchymal expression signature was found primarily in the … See more One important question for the potential targeting of MARCO+ macrophages is where they originate from and how they are recruited to the tumor.
