摘要:
Aim: To assess the chemo-immunomodulatory effects of doxorubicin-loaded cerium oxide nanoparticles coated with oleyl amine-linked cyclic RGDfK peptide (CeNP+Dox+RGD) to target both gliomas and its tumor microenvironment (TME) via integrin receptors. Materials & methods: CeNP+Dox+RGD nanoparticles are synthesized by the sequential addition of cerium III chloride heptahydrate, beta-cyclodextrin, oleic acid, and F127 micelle (CeNP). Doxorubicin was then loaded into CeNPs and coated with oleyl amine-linked cyclic RGDfK peptide to form stable CeNP+Dox+RGD nanoparticles. Results: CeNP+Dox+RGD nanoparticles crossed blood-brain barrier (BBB) effectively and demonstrated threefold enhanced survivability in glioma-bearing mice. The IHC profiling of glial tumor cross-sections showed increased CD80 expression (M1 TAMs) and decreased arginase-1 expression (M2 TAMs). Conclusion: CeNP+Dox+RGD can be an immunotherapeutic treatment option to combat glioblastoma.
