摘要: 恶性脑胶质瘤是最常见的成人原发性肿瘤,具有手术无法完全切除、复发率高的特点。随着分子生物技术的发展,基因治疗逐渐成为一种有望治愈脑胶质瘤的新手段。基因载体是将治疗基因导入肿瘤细胞的载体,在基因治疗中起关键的作用。目前,常用基因治疗载体分为生物载体和非生物载体两大类。生物载体包括病毒载体、细菌载体和干细胞载体,研究显示虽然生物载体靶向性好,转导效率高但存在遗传安全隐患;非生物载体包括脂质体和纳米材料类载体,这类载体制备简单,安全可控但转导效率低。因此建立安全有效的脑胶质瘤治疗基因导入系统,寻找具有良好靶向性的基因载体,成为研究者们关注的问题。

Abstract: With the development of biomolecular technology, gene therapy has been demonstrated to be a promising treatment for the malignant glioma which is the most common type of primary brain tumor in adults. The vectors play important roles in gene therapy by transporting the therapy gene into target tumor cells. The vectors employed for glioma gene therapy are widely developed and used in clinical trials. There are mainly two kinds of gene vectors, biological and non-biological vectors. Biological vectors, including virus-like, bacterial, and stem cells, can efficiently delivery the gene into target tumor cells, but have potential genetic dangers. However, non-biological vectors, including liposomes and nanoparticles, which are of highly genetic safety can not transport the gene efficiently. Therefore, it is important to find targetable and genetically-safe vectors to establish highly-efficient gene therapy methods.
