摘要

高效、安全地将静脉化疗药物通过血脑屏障（BBB）输送到脑肿瘤的精确位置是胶质瘤治疗的关键因素。在这里，我们介绍了一种生物仿生纳米平台（T7-M-C/S），它由盐酸伊立替康（CPT11）及其生物活性代谢物7-乙基-10-羟基喜树碱（SN38）组成的核心，周围是一层T7肽修饰的巨噬细胞膜。CPT11 自发地与 SN38 组装成稳定的水分散纳米颗粒（C/S），大大提高了 SN38 的水溶性。经过修饰的多肽与巨噬细胞表达的固有蛋白相结合，使纳米平台具有更高的生物利用度和强大的胶质瘤靶向能力，最终实现卓越的治疗效果。这些发现凸显了一种利用巨噬细胞膜、具有高载药量特点的给药系统，有望为胶质瘤治疗带来巨大潜力。

T7 Peptide-modified macrophage membrane-coated nanoplatform for enhanced glioma treatment

The efficient and secure delivery of intravenous chemotherapeutic agents across the blood–brain barrier (BBB) to the precise location of a brain tumor is a crucial element in glioma treatment. Herein, we introduce a biomimetic nanoplatform (T7-M-C/S) comprising a core made up of irinotecan hydrochloride (CPT11) and its bioactive metabolite, 7-Ethyl-10-hydroxycamptothecin (SN38), surrounded by a layer of T7-peptide-modified macrophage membrane. CPT11 spontaneously assembles with SN38 into stable and water-dispersible nanoparticles (C/S), greatly enhancing the water solubility of SN38. The integration of the modified peptide with the inherent proteins expressed by macrophage cells confers the nanoplatform with enhanced bioavailability and robust glioma-targeting abilities, ultimately resulting in superior therapeutic outcomes. These discoveries highlight a drug delivery system characterized by a high drug loading capacity, leveraging the macrophage membrane, and promising significant potential for glioma treatment.
