摘要

针对Diamond-Blackfan贫血(DBA)的基因治疗策略一直受到多重和异质性致病突变的阻碍。现在的一项研究表明,调节GATA1表达足以解决DBA模型和患者来源样本中的红细胞成熟阻滞。Voit等人首先发现了内源性调控元件(hG1E-GATA1)在人造血细胞中引导GATA1的红细胞限制性表达,然后表明hG1E-GATA1治疗支持红细胞生成而不影响造血干细胞功能。随后,他们证明hG1E-GATA1治疗可以改善DBA模型中的红细胞输出,以及来自DBA个体的样本,包括体内,正如异种移植试验所表明的那样。Voit等人利用单细胞转录组学发现,hG1E-GATA1治疗可逆转dba特有的红系转录失调。最后,整合位点分析显示,hG1E-GATA1慢病毒载体的基因组整合谱与其他慢病毒基因治疗产品的基因组整合谱相当,因此支持该方法作为临床测试的良好候选方法。
