胶质母细胞瘤(GBM)是一种无法治愈的原发性星形细胞脑肿瘤,由与血管龛密切相关的胶质瘤干细胞(GSC)隔室驱动。GSC表型是异质的,范围从前神经到间充质样,后者的特点是更大的侵袭性。在这里,我们记录的分泌(血管分泌)的作用,内皮细胞及其衍生的细胞外囊泡(EV)作为驱动程序的原神经间充质重编程的GSC。这些变化涉及基质金属蛋白酶(MMPs)和NFκB的激活以及NOTCH的失活,同时改变对化疗的反应性并驱动脑中的浸润性生长。我们的研究结果表明,EV介导的血管分泌相互作用影响GBM中细胞干性的性质,并对疾病生物学和治疗产生影响。胶质瘤干细胞样细胞(GSC)在前神经向间充质转化过程中表现出可塑性。在这里,作者表明,来自内皮细胞的细胞外囊泡可以通过激活MMP和NFkB以及灭活NOTCH来促进GSC的这种转变。
Glioblastoma (GBM) is an incurable form of primary astrocytic brain tumor driven by glioma stem cell (GSC) compartment closely associated with the vascular niche. GSC phenotypes are heterogeneous and range from proneural to mesenchymal-like, the latter characterised by greater invasiveness. Here we document the secretory (angiocrine) role of endothelial cells and their derived extracellular vesicles (EVs) as drivers of proneural-to-mesenchymal reprogramming of GSCs. These changes involve activation of matrix metalloproteinases (MMPs) and NFκB, and inactivation of NOTCH, while altering responsiveness to chemotherapy and driving infiltrative growth in the brain. Our findings suggest that EV-mediated angiocrine interactions impact the nature of cellular stemness in GBM with implications for disease biology and therapy. Glioma stem-like cells (GSCs) exhibit plasticity during proneural-to-mesenchymal transition. Here the authors show that extracellular vesicles from endothelial cells can promote this transition of GSCs through activation of MMPs and NFkB, and inactivation of NOTCH.
