Abstract
Glioma treatment remains a challenge owing to unsatisfactory targeted chemotherapy, where the blood–brain barrier (BBB) hinders the efficient uptake of therapeutics into the brain. Vasculogenic mimicry (VM) formed by invasive glioma cells negatively affects the treatment of glioma. Herein, we developed a targeted biomimetic drug delivery system comprising a doxorubicin-loaded platelet membrane-coated nanogel (DOX@PNGs). The nanogels provide great redox/pH dual responsiveness, while the platelet membrane (PLTM) promotes stability and circulation time. In vitro cellular uptake and in vivo imaging experiments demonstrated that the DOX@PNGs delivery system could penetrate the BBB, target gliomas, and destruct VM. DOX@PNGs increased drug penetration and prolonged mouse survival time during the treatment of orthotopic gliomas. These results indicate this biomimetic drug delivery system to be promising for glioma treatment and may be clinically translated in the future.
