摘要
基因治疗被认为是治愈疾病的最佳方式,但是本世纪初一系列不良事件发生,使基因治疗一度受挫。通过几年来研究和改进,慢病毒以其高转染率、靶细胞中稳定的表达和良好的安全性,为基因治疗又带来了新的曙光。目前慢病毒载体在HIV感染、地中海贫血、X连锁的肾上腺脑白质营养不良等疾病中已开展了相关的临床试验,获得了一定的治疗效应,尚未观察到严重的与基因治疗相关的不良事件。初步取得的成果使基因治疗再次成为人们关注的热点。本文就基因治疗为何受阻于病毒载体问题,慢病毒载体的高效安全特征和慢病毒载体的制备问题进行了综述。
Gene therapy has been considered as one of the optimal treatments. Although, at the beginning of this century, a series of unexpected side effects brought gene therapy into depression, the improved lentiviral vectors, which characterised by high efficiency transfection, stable expression in target cells and good biosafety, have been applied in clinical trials in recent years and acquired a certain clinical improvements. Nowadays gene therapy becomes an eye-catch- ing field. This review discusses the gene therapy how blocked by lentiviral vectors, the high efficiency and biosatety of lentiviral vectors, the improvement of lentiviral vector preparation and so on.
