美国药监局批准了CRISPR人体试验计划

2016-06-23 佚名 生物谷

上周,美国宾夕法尼亚大学的研究人员们提出了一项计划,他们希望能够用CRISPR来编辑人体的免疫细胞,进而来治疗相关的疾病。该计划最近已经获得了美国食品药品监督管理局(FDA)的批准。如果该计划能够顺利实施,将是第一次用CRISPR系统进行的人体基因编辑试验。CRISPR/Cas9是一种基于细菌防御系统改造而来的基因编辑系统,可以利用gRNA引导DNA剪切蛋白在特定位点完成剪切,因而具有很好的特异性

上周,美国宾夕法尼亚大学的研究人员们提出了一项计划,他们希望能够用CRISPR来编辑人体的免疫细胞,进而来治疗相关的疾病。该计划最近已经获得了美国食品药品监督管理局(FDA)的批准。如果该计划能够顺利实施,将是第一次用CRISPR系统进行的人体基因编辑试验。

CRISPR/Cas9是一种基于细菌防御系统改造而来的基因编辑系统,可以利用gRNA引导DNA剪切蛋白在特定位点完成剪切,因而具有很好的特异性。该基因编辑系统从提出到现在已经历经四年,而且在很多生物体上面都进行了实验,而且从原型到现在的CRISPR基因剪切系统已经有了很多的优化。同时,该系统的专利之争也从未停歇。

CRISPR基因编辑系统的人体试验面临着诸多的问题,例如伦理、法律、安全等等。同时对于该基因编辑系统用于人体实验也存在监管问题。上周,美国宾夕法尼亚大学的研究人员们,向美国FDA提交了一项申请,本网站也已经在《 利用CRISPR基因编辑技术治疗癌症? 》中进行了相关报道。该申请主要目的在于,抽取人体的免疫细胞(T淋巴细胞),经过CRISPR基因改造后的这些免疫细胞,被重新导入到人体中,进而可以用来治疗癌症。值得注意的是,该项目并非是编辑人体胚胎细胞,因此不会有“转基因人”的出现。

尽管美国FDA已经批准了该研究申请,该研究项目还需要同时获得项目所在医疗单位的批准。如果顺利的话,该项目还会得到科技大亨 西恩·帕克的资助,将通过他在今年四月成立的 帕克癌症免疫治疗研究所对这个计划给予资助。虽然,目前宾夕法尼亚大学的课题组还没有正式给出该项目执行的时间表,但是在可以预见的未来,我们或许会看到CRISPR给人们带来更多的惊喜。

张锋:利用CRISPR发现未知基因功能

基因编辑,尤其是CRISPR/Cas9系统,从某种意义上来说就像是一辆正在生产的闪亮新车,在构建主要框架的同时也开始启动,而且还准备开始一路飚车。 自2012年底CRISPR/Cas9最初被用于基因编辑之后,这个前途光明的技术已经被应用到了许多研究领域,而且随着技术的改良,越来越多的研究团队利用CRISPR进行大规模的遗传筛选,比如用于识别导致癌症抵抗治疗的突变,或者加速药物靶标评估。RNA

Cancer Discovery:细胞对CRISPR的应答不容忽视

这两年几乎人人都在谈论CRISPR基因组编辑,那么细胞对这个系统的闯入作何感想呢?Cancer Discovery杂志最近发表的一项研究指出,细胞会对CRISPR-Cas9产生一种不容忽视的应答。 细菌一直在与病毒或入侵核酸进行斗争,为此它们演化出了多种防御机制,CRISPR-Cas适应性免疫系统就是其中之一。规律成簇的间隔短回文重复CRISPR与内切酶Cas9的组合,可以在引导RNA的指引
