Abstract
Poor prognosis in high-grade gliomas is mainly due to fatal relapse after surgical resection in the absence of efficient chemotherapy, which is severely hampered by the blood-brain barrier. However, the leaky blood-brain-tumour barrier forms upon tumour growth and vascularization, allowing targeted nanocarrier-mediated drug delivery. The homotypic targeting ability of cell-membrane fragments obtained from cancer cells means that these fragments can be exploited to this aim. In this experimental work, injectable nanoemulsions, which have a long history of safe clinic usage, have been wrapped in glioma-cell membrane fragments via co-extrusion to give targeted, homogeneously sized, sterile formulations. These systems were then loaded with three different chemotherapeutics, in the form of hydrophobic ion pairs that can be released into the target site thanks to interactions with physiological components. The numerous assays performed in two-dimensional (2D) and three-dimensional (3D) cell models demonstrate that the proposed approach is a versatile drug-delivery platform with chemo-tactic properties towards glioma cells, with adhesive interactions between the target cell and the cell membrane fragments most likely being responsible for the effect. This approach's promising translational perspectives towards personalized nanomedicine mean that furtherstudies are foreseen for the future.
Overview
- The study focuses on the poor prognosis of high-grade gliomas and the need for efficient chemotherapy after surgical resection. The blood-brain barrier is a significant barrier to chemotherapy, but the leaky blood-brain-tumor barrier formed during tumor growth allows targeted nanocarrier-mediated drug delivery. The study uses injectable nanoemulsions wrapped in glioma-cell membrane fragments via co-extrusion to create targeted, homogeneously sized, sterile formulations. These systems are loaded with three different chemotherapeutics in the form of hydrophobic ion pairs that can be released into the target site. The study demonstrates the versatility of the proposed approach as a drug-delivery platform with chemo-tactic properties towards glioma cells. The study aims to answer the question of whether the proposed approach can be used for personalized nanomedicine in the future. The hypothesis being tested is that the proposed approach can improve the efficacy of chemotherapy in high-grade gliomas. The methodology used for the experiment includes the use of two-dimensional (2D) and three-dimensional (3D) cell models to evaluate the chemo-tactic properties of the proposed approach.
