Nature:治疗脑肿瘤新策略——突破脑屏障,对肿瘤实行免疫监视!

2020-01-18 不详 生物探索

众所周知,脑屏障可以保护人脑,防止危险病原体进入。而胶质母细胞瘤是成人颅内最常见的恶性肿瘤,目前尚无非常有效的治疗方法,临床治疗主要是手术切除,再辅以放化疗,但预后生存率仅为18个月,因此探索新的治疗途径非常重要。

众所周知,脑屏障可以保护人脑,防止危险病原体进入。而胶质母细胞瘤是成人颅内最常见的恶性肿瘤,目前尚无非常有效的治疗方法,临床治疗主要是手术切除,再辅以放化疗,但预后生存率仅为18个月,因此探索新的治疗途径非常重要。

近日,耶鲁大学的研究人员在《Nature》杂志上报道了一种新颖的脑肿瘤治疗策略,血管内皮生长因子C(Vascular EndothelialGrowth Factor C,VEGF-C)的异位表达有可能增加脑膜淋巴管,从而实现免疫监视,启动T细胞介导的脑肿瘤免疫,达到治疗效果。


DOI: 10.1038/s41586-019-1912-x

脑膜淋巴管分布于硬脑膜周围,将大脑与外周淋巴系统紧密维系。在此,研究者用C57BL/6同基因细胞系GL261构建小鼠胶质母细胞瘤模型,分别用腺相关病毒载体(AAV 9)和mRNA传递载体表达VEGF-C。


VEGF-C介导的对胶质母细胞瘤的保护作用依赖于引流淋巴结和T细胞

将VEGF-C注入患有胶质母细胞瘤的小鼠的脑脊液中,研究者发现脑肿瘤的T细胞反应水平增加。当与免疫治疗中常用的免疫系统检查点抑制剂联合使用时,VEGF-C治疗可显著延长小鼠的生存期。

该研究揭示了VEGF-C可以促进肿瘤免疫监视的能力,通过增加淋巴引流来克服中枢神经系统(central nervoussystem, CNS)对胶质母细胞瘤的免疫忽视,从而治疗胶质母细胞瘤。目前,研究人员正在建立新的实验模型,研究其他神经系统疾病的血管网络的功能机制,同时探究其治疗潜力。
