Objective::Glioma is the most common and aggressive primary brain tumor. Here, we aimed to establish a nano-drug carrier system to traverse the blood-brain barrier for the treatment and inhibition of glioma migration.Methods::The synthesis of bovine serum albumin protected-silver nanoclusters (BSA-AgNCs) was performed using chemical reduction. The drug paclitaxel (PTX) can be loaded into BSA-AgNCs through electrostatic and hydrophobic interactions to formulate spherical BSA-AgNC-PTX nanoparticles (BSA-AgNC-PTX NPs). A glioma mouse model was established by injecting U251-GFP-Luc cells into the mouse striatum, and all surgical procedures were approved by the Animal Ethics Committee of Nanchang University (SYXK2019-0003) on December 29, 2019.Results::The BSA-AgNC-PTX NPs were able to efficiently pass through the blood-brain barrier, both in vitro and in vivo, to deliver the drug to the tumor site. The in vivo assessment of BSA-AgNC-PTX NPs in glioblastoma multiforme-bearing mice revealed the significant inhibition of tumor growth and migration, prolonging the survival of the mice.Conclusion::These results indicated that BSA-AgNCs might represent an ideal nanocarrier for the treatment of glioma and has the potential to be used in the treatment of a variety of central nervous system diseases.“,”Objective::Glioma is the most common and aggressive primary brain tumor.
