摘要
Glioblastoma multiforme(GBM)is a highly aggressive and lethal brain tumor with limited treatment options.To improve therapeutic efficacy,we developed a novel multifunctional nanoplatform,GM@P(T/S),comprised of polymeric nanoparticles coated with GBM cell membranes as well as co-loaded with temozolomide(TMZ)and superparamagnetic iron oxide(SPIO)nanoparticles.The successful preparation was confirmed in terms of particle size,morphology,stability,the in vitro drug release,and cellular uptake assays.We demonstrated that GM@P(T/S)exhibited the enhanced homotypic targeting,the prolonged blood circulation,and efficient bloodbrain barrier penetration in both in vitro and in vivo studies.The combination of TMZ and SPIO nanoparticles within GM@P(T/S)synergistically improved chemo-radiation therapy,leading to a reduced tumor growth,an increased survival,and minimal systemic toxicity in the orthotopic GBM mouse models.Our findings suggest that GM@P(T/S)holds a great promise as a targeted and efficient therapeutic strategy for GBM.
