hybrid-targeting nanoparticle for penetrable delivery of temozolomide to enhance glioblastoma therapy

英文摘要

hemotherapy for glioblastoma (GBM) has not achieved the desired outcome due to inefficient bloodbrain barrier (BBB) penetration and limited tumor-specific drug accumulation. Strategies that employ bioinspired nanoparticles to enhance targeted drug accumulation can help improve therapeutic efficacy. In this work, a novel nanoparticle, PCM@TMA-lip, exhibiting hybrid-targeting capabilities, is presented, with an engineered cell membrane coated on a lipid core. The membrane modified with a biologically derived peptide enables PCM@TMA-lip to evade immune clearance and enable precise tumor targeting. The lipid core with docosahexaenoic acid (DHA)-conjugated temozolomide (TMZ) enhances FABP7-mediated uptake, promotes lysosomal escape via lipid peroxidation, and reduces tumor migration and drug resistance. In vitro, PCM@TMA-lip inhibited tumor cell malignancy and suppressed the growth of 3D spheroids. In vivo, it suppressed tumorprogression, reduced Ki67+ proliferation, increased TUNEL+ apoptosis, and prolonged survival in GBM-bearing mice, highlighting its potential as an effective strategy to improve GBM chemotherapy.
