Polymeric nanoparticles (PNPs) may efficiently deliver in vivo therapeutics to tumors when conjugated to specific targeting agents. Gint4.T aptamer specifically recognizes platelet-derived growth factor receptor β and can cross the blood–brain barrier (BBB). We synthesized Gint4.T-conjugated PNPs able of high uptake into U87MG glioblastoma (GBM) cells and with astonishing EC50 value (38 pM) when loaded with a PI3K-mTOR inhibitor. We also demonstrated in vivo BBB passage and tumor accumulation in a GBM orthotopic model.

通过血脑屏障靶向胶质母细胞瘤的纳米系统的适体功能化。

当与特定的靶向剂偶联时,聚合物纳米颗粒(PNP)可以有效地将体内治疗剂传递给肿瘤。Gint4.T适体可特异性识别血小板衍生的生长因子受体β,并可穿过血脑屏障(BBB)。我们合成了Gint4.T偶联的PNP,能够在U87MG胶质母细胞瘤(GBM)细胞中高摄取,并在装载PI3K-mTOR抑制剂时具有惊人的EC 50值(38 pM)。我们还证明了在GBM原位模型中的体内BBB传递和肿瘤蓄积。
