脑肿瘤严重威胁人类生命,其特有的屏障结构阻碍了药物有效进入。以脑胶质瘤为例,对现有脑肿瘤主要靶向策略作一简要综述,并提出了脑肿瘤靶向递药的新理念——系统靶向(或全过程靶向)递药,即集脑肿瘤发生发展各阶段特征靶向策略于一体,设计对脑肿瘤发生发展各阶段具有靶向功能的纳米递药系统,以实现更为有效的脑肿瘤靶向治疗目标。
Brain tumor poses a serious threat to human health. Its unique barrier substantially prevents drug entry. This review summarizes recent advances in brain tumor-targeting strategies and puts forward a new concept thereof, namely systematic targeting or whole-process targeting. This new concept combines targeting strategies aiming at each development stage of brain cancer in order to design nanoscale drug delivery system targeting each development stage of brain cancer and realize effective targeted treatment on brain cancers.
