使用病毒和非病毒介导的离体基因转移可以成功地进行研究性治疗。事实上,最近的临床试验已经证实了转基因 T 细胞改善和恢复健康的潜力。最近,睡美人(SB)转座子/转座酶系统已应用于临床试验,以稳定插入嵌合抗原受体(CAR)来重定向T细胞特异性。我们讨论了 SB 系统可用于基因治疗的背景,并描述了 SB 修饰的 CAR+ T 细胞的人体应用。我们重点关注与自然受到转座子再动员的人类基因组背景下的插入突变有关的理论问题,以及过去十年使用 SB 转座子来定义诱发癌症的基因的实验证据。这些发现被纳入使用 SB 转座子治疗人类疾病的背景中。
Investigational therapy can be successfully undertaken using viral- and non-viral-mediated ex vivo gene transfer. Indeed, recent clinical trials have established the potential for genetically modified T cells to improve and restore health. Recently the Sleeping Beauty (SB) transposon/transposase system has been applied in clinical trials to stably insert a chimeric antigen receptor (CAR) to redirect T-cell specificity. We discuss the context in which the SB system can be harnessed for gene therapy and describe the human application of SB-modified CAR+ T cells. We have focused on theoretical issues relating to insertional mutagenesis in the context of human genomes that are naturally subjected to remobilization of transposons and the experimental evidence over the last decade of employing SB transposons for defining genes that induce cancer. These findings are put into the context of the use of SB transposons in the treatment of human disease.
