Glioblastoma multiform (GBM) is the most prevalent and deadliest primary brain malignancy in adults, whose median survival rate does not exceed 15 months after diagnosis. The conventional treatment of GBM, including maximal safe surgery followed by chemotherapy and radiotherapy, usually cannot lead to notable improvements in the disease prognosis and the tumor always recurs. Many GBM characteristics make its treatment challenging. The most important ones are the impermeability of the blood-brain barrier (BBB), preventing chemotherapeutic drugs from reaching in adequate amounts to the tumor site, intratumoral heterogeneity, and roles of glioblastoma stem cells (GSCs). To overcome these barriers, the recently-developed drug-carrying approach using nanoparticles (NPs) may play a significant role. NPs are tiny particles, usually less than 100 nm showing various diagnostic and therapeutic medical applications. In this regard, cell membrane (CM)-coated NPs demonstrated several promising effects in GBM in pre-clinical studies. They benefit from fewer adverse effects due to their specific targeting of tumor cells, biocompatibility because of their CM surfaces, prolonged half-life, easy penetrating of the BBB, and escaping from the immune reaction, making them an attractive option for GBM treatment. To date, CM-coated NPs have been applied to enhance the effectiveness of major therapeutic approaches in GBM treatment, including chemotherapy, immunotherapy, gene therapy, and photo-based therapies. Despite the promising results in pre-clinical studies regarding the effectiveness of CM-coated NPs in GBM, significant barriers like high expenses, complex preparation processes, and unknown long-term effects still hinder its mass production for the clinic. In this regard, the current study aims to provide an overview of different characteristics of CM-coated NPs and comprehensively investigate their application as a novel treatment approach in GBM.
多形性胶质母细胞瘤(GBM)是成人中最常见、最致命的原发性脑恶性肿瘤,其确诊后的中位生存期不超过15个月。GBM的传统治疗方法,包括最大限度的安全手术,随后进行化疗和放疗,通常无法显著改善疾病预后,肿瘤总是会复发。GBM的许多特性使其治疗具有挑战性。其中最重要的是血脑屏障(BBB)的不透性,这使得化疗药物无法足量到达肿瘤部位、肿瘤内异质性以及胶质母细胞瘤干细胞(GSCs)的作用。为了克服这些障碍,最近开发的使用纳米颗粒(NPs)的载药方法可能会发挥重要作用。NPs是微小颗粒,通常小于100纳米,具有多种诊断和治疗医学应用。在这方面,细胞膜(CM)包被的NPs在临床前研究中对GBM显示出几种有前景的效果。它们因对肿瘤细胞的特异性靶向而副作用较少,因其CM表面而具有生物相容性,半衰期延长,易于穿透血脑屏障,并能逃避免疫反应,使其成为GBM治疗的一个有吸引力的选择。迄今为止,CM包被的NPs已被应用于提高GBM治疗中主要治疗方法的有效性,包括化疗、免疫治疗、基因治疗和光基治疗。尽管在临床前研究中CM包被的NPs对GBM的有效性取得了有前景的结果,但高成本、复杂的制备过程和未知的长期影响等重大障碍仍然阻碍其大规模临床生产。在这方面,本研究旨在概述CM包被的NPs的不同特性,并全面研究它们作为GBM新型治疗方法的应用。
