摘要
胶质瘤是最常见的恶性脑肿瘤类型。尽管医学取得了重大进展,但胶质瘤仍然无法治愈,并且死亡率很高。尽管已经确定了许多具有诊断价值的生物标志物,并且在预后预后方面取得了重大进展,但在过去的 30 年中,治疗并没有得到平行改善。本综述总结并讨论了与胶质瘤相关的最新发现的三个方面,目的是突出胶质瘤特异性药物针对起源细胞、微环境和代谢的优势。鉴于胶质瘤的异质性,各种细胞群被认为是肿瘤的可能来源。根据细胞获得的突变,据信神经干细胞/祖细胞,少突胶质祖细胞、成熟神经元和神经胶质细胞可以启动细胞转化为恶性表型。致瘤性水平似乎与给定细胞群的成熟度呈负相关。胶质瘤的微环境包括免疫细胞、成纤维细胞和血管细胞等非癌细胞,以及分泌分子和细胞外基质,所有这些成分在肿瘤的发生和发展过程中都起着至关重要的作用。我们将详细讨论肿瘤微环境如何刺激和驱动非肿瘤细胞群向肿瘤支持细胞或神经胶质瘤细胞的转化。代谢重编程是神经胶质瘤的一个关键特征,被认为反映了对肿瘤细胞增殖、生长、和生存。IDH 基因的突变可以影响代谢重编程,并可能在神经胶质瘤细胞中产生一些脆弱性,例如异常的脂质代谢和对内质网应激 (ERS) 的敏感性。我们将分析恶性胶质瘤的突出代谢特征和调控胶质瘤代谢的关键途径。本综述旨在为基于肿瘤细胞群、微环境和代谢特性的神经胶质瘤疗法的开发提供概念背景。
