Description

一种用基因编辑改造原代细胞的DNA模板及定点插入方法
技术领域
本发明涉及目的基因的定点插入,具体是利用电转技术结合基因编辑技术通过非病毒方法将目的基因定点整合到细胞系或原代细胞的基因组中,实施例中产生的嵌合抗原受体T(CAR-T)细胞可以用于白血病的治疗。
背景技术
目前主要是通过传统的慢病毒或逆转录病毒手段将目的基因整合到人原代T/NK细胞基因组中,但是该方法的不足之处是目的基因会被随机插入,如果能够将外源目的基因定点插入到细胞基因组中,能够在一定程度上提高基因工程改造过的人原代T/NK细胞的安全性和有效性,在临床上发挥更大的作用。目前,CRISPR-Cas9/Cpf1系统在实现对基因敲除方面已经运用的很成熟。但是通过CRISPR-Cas9/Cpf1系统实现将目的基因定点插入细胞系特别是原代细胞的基因组的技术,虽然已经有了一定的发展,但是插入的效率仍然很低。
目前在人原代T/NK细胞上,通过CRISPR-Cas9/Cpf1系统将目的基因定点整合到人原代T细胞的方法,主要是依赖于腺相关病毒(AAV)提供的单链DNA,作为Cas9/Cpf1定点切割基因组后同源重组修复(HDR)的供体DNA模板。但是腺相关病毒(AAV)在临床治疗过程中仍然可能会对机体产生潜在的危险、制备也较为复杂和不经济。目前还有研究将双链的线性DNA作为同源重组修复的供体DNA模板,对人原代T/NK细胞进行改造,但是双链的线性DNA制备较为复杂,且GMP制备不成熟。我们通过改造环状(circular)质粒载体DNA,使之成为同源重组修复的供体DNA模板,更高效地将目的基因定点插入到细胞系和人原代T/NK细胞的基因组中,从而实现目的基因在细胞系和人原代T/NK细胞基因组中的定点整合,增加免疫细胞治疗疾病的安全性和有效性。
发明内容
本发明的目的是提供一种用基因编辑改造原代细胞的DNA模板及定点插入方法,本发明主要通过对CRISPR-Cas9/Cpf1定点插入系统中依赖的同源重组修复的供体DNA质粒载体模板进行改造,减小质粒载体的长度并在同源臂两端加入guide RNA识别的DNA序列(Cas9/Cpf1-cleavage sequence,CCS),使得Cas9/Cpf1 RNP复合物能在定点切割基因组的同时把环状的供体DNA质粒载体切割成线性的供体DNA模板。该方法能够不依赖病毒递送同源重组修复的供体DNA模板,将基因定点整合到细胞系或人原代T/NK细胞的基因组中,此种方法制备的定点插入的CAR-T细胞与依赖AAV病毒产生的定点插入的CAR-T细胞具有同等的体外杀伤和体内抗肿瘤效果,实现了定点插入CAR-T技术的突破。
本发明采用以下技术方案:
一种用基因编辑改造原代细胞的DNA模板,包括质粒、构建于质粒上的需要导入的目的基因、靶序列上下游的同源性序列(同源臂)和guide RNA识别的DNA序列。
进一步地,所述质粒为pUC57、pUC57截短突变质粒pMini以及pMiniZ,pMini的核苷酸序列如SEQ ID NO:5所示,pMiniZ的核苷酸序列如SEQ ID NO:32所示。
进一步地,目的基因的每一侧均具有一个同源性序列和guide RNA识别的DNA序列。其中,基因编辑蛋白通常为Cas9/Cpf1,可将guide RNA的DNA序列表示为Cas9/Cpf1-cleavage sequence,CCS。
本发明还提供了一种基于权利要求1所述DNA模板的目的基因定点插入方法,包括如下步骤:
步骤1、选取要定点插入目的基因的基因组位点,并根据位点选择CRISPR-Cas9/Cpf1系统识别插入位点的guide RNA;
步骤2、设计合成供体DNA模板,供体DNA模板含有目的基因、目的基因两侧的同源臂序列以及guide RNA识别的DNA序列;
步骤3、合成识别插入位点的guide RNA,表达纯化基因编辑蛋白;
步骤4、将步骤3中的guide RNA和基因编辑蛋白体外结合后,再与步骤2中带有目的基因和同源臂以及识别位点的质粒载体混合,最后与细胞混合,电转,完成目的基因的定点插入和细胞的改造。
进一步地,所述步骤3中,质粒载体为pUC57截短突变质粒pMini,pMini的核苷酸序列如SEQ ID NO:5所示。
进一步地,基因编辑蛋白为SpCas9或LbCpf1或AsCpf1等。
进一步地,步骤1中插入位点为TCRα或RAB11a位点,步骤2目的基因为CAR或EGFP基因,步骤5中细胞为HEK293T或人原代T/NK细胞。
进一步地,步骤2中同源臂为任意大小。
进一步地,步骤5中guide RNA和Cas9/Cpf1蛋白在体外室温或37℃结合10-20min。
进一步地,步骤5中采用CeletrixTM或BTX电转系统。
上述方案中,可以采用流式细胞术检测目的基因的表达,并与依赖病毒提供DNA模板产生定点插入的人原代CAR-T细胞对比体外和体内的抗肿瘤功能。
本发明的有益效果是:
通过非病毒方法将目的基因定点整合到人原代T细胞中,避免了通过病毒感染和非定点整合带来的潜在的风险,如肿瘤致病性。同时,定点插入产生的CAR-T细胞与随机插入的细胞相比,有更好的安全性和有效性。此外,该方法简化了人原代CAR-T细胞的生产工艺,节约了生产成本,具有很大的临床应用潜力和商业价值。

5、3T3-CD19作为抗原靶标刺激CAR-T细胞富集,CAR-T细胞与3T3-CD19(APC)的比例大约为4:1,刺激一周后,CAR-T细胞的比例可以达到50%以上,如图8所示,并且临床上已有应用通过抗原刺激增殖后的CAR-T细胞的先例,本实施例可以通过APC刺激CAR-T细胞增殖,得到足够的CAR-T细胞应用于临床。
6、为了研究不同pMini-CCS-TRAC-CAR和RNP的比例对CAR基因插入效率的影响,本实施例主要探究了如图9所示的pMini-CCS-TRAC-CAR和RNP的比例,结果显示,不同比例的RNP和pMini-CCS-TRAC-CAR都可以使基因的插入效率达到10%左右,其中,180pmol RNP,25μg的质粒载体达到最大的插入效率,见图9a,b。
7、已有研究表明不同的Cas9进入细胞核内依赖于核定位信号(NLS)序列,在本实施例中Cas9-NLS蛋白有助于携带pMini-CCS-TRAC-CAR进入细胞核增加基因插入效率,所以本实施例探究了增加或者减少CCS位点或者增加Cas9蛋白上的核定位信号是否会影响基因插入效率,结果显示只有一个或者没有CCS,目的基因的插入效率大约只有0-3%,而有三个CCS位点与两个CCS位点相比,并没有增加目的基因的插入效率,见图10,而将NLS从2个增加到4个,CAR基因的插入效率并没有增高,见图11。
8、已有研究表明,不同同源臂长度也会影响基因插入的效率,故本实施例中构建了含有不同同源臂长度的pMini载体,结果表明100bp,300bp,500bp,800bp的同源臂长度都可以让目的基因的插入效率达到10%左右,其中800bp的同源臂长度基因插入效率较其他同源臂长度相对较高,见图12。
9、为了进一步探究跟细胞周期相关的小分子药物或者蛋白对T细胞基因插入效率的影响,本实施例中在RNP和pMini-CCS-TRAC-CAR载体共同电转到T细胞后,加入0.1μM的Brefeldin A,24小时后,换上不含Brefeldin A的培养基,6天后检测目的基因的插入效率,结果显示加入0.1μM Brefeldin A后,目的基因的插入效率有些许的降低,见图13a,而加入30ng/ml的纯化的CCND1蛋白后,目的基因的插入效率比不加CCND1的增加了大约15-20%,如图13b所示。
10、已有研究报道,带甲基硫代磷酸修饰的guide RNA能够增加人原代T细胞的敲除效率,本实施例中以上的结果用的guide RNA都是用的带甲基硫代磷酸修饰的guideRNA,为了节约成本,本实施例也检测不带修饰的guide RNA对目的基因插入效率的影响,结果显示,不带修饰的guide RNA比带修饰的guide RNA的插入效率大约低了15%左右,如图14所示。因此,在未来临床研究中,也可以用不带修饰guide RNA作为目的基因插入的原料。
11、本实施案例中通过本发明质粒载体作为CRISPR-Cas9切割后HDR的模板产生的CAR-T细胞命名为p-TRAC-CAR T细胞,传统的腺相关病毒作为CRISPR-Cas9切割后HDR的模板产生的CAR-T细胞命名为AAV-TRAC-CAR T细胞,对比两种CAR-T细胞的增殖能力,结果如图15a所示,p-TRAC-CAR T细胞在前3天的增殖能力比AAV-TRAC-CAR T细胞相对较弱,但在12天左右几乎与AAV-TRAC-CAR T细胞相同。
12、两种CAR-T细胞在遇到肿瘤抗原3T3-CD19细胞系时的增殖能力检测。在24孔板里铺上3T3-CD19细胞,用DMEM培养基培养过夜后,将表达CAR的T细胞调成CAR+细胞为1million/ml,用3T3-CD19细胞刺激CAR-T细胞增殖,检测两种方法产生的CAR-T细胞的增殖能力,如图15b所示,p-TRAC-CAR T细胞在遇到肿瘤抗原在起始时的增殖能力弱于AAV-TRAC-CAR T细胞,但是在经过5-6周刺激后,p-TRAC-CAR T细胞的增殖数量与AAV-TRAC-CART细胞基本一致。
13、两种CAR-T细胞在遇到靶标白血病肿瘤细胞系NALM6-EGFP-Luciferase时的杀伤能力检测。在每个96孔圆形细胞培养板里放10000个NALM6-EGFP-Luciferase肿瘤细胞,CAR-T细胞按Effector:Target比例为2:1,1:1,1:2,1:4,1:8,1:16,1:32加入,每组设三个重复,每个体积大约为100μl,共培养18小时后,加入荧光素底物,用酶标仪测量荧光素的发光情况,通过荧光素的发光情况计算p-TRAC-CAR T细胞和AAV-TRAC-CAR T细胞的杀伤能力。如图15c所示,p-TRAC-CAR T细胞的杀伤能力与AAV-TRAC-CAR T细胞的杀伤能力没有统计学差异。
14、通过质谱流式检测两种CAR-T细胞在经过抗原刺激前后40种标志物的变化,通过t-Distributed Stochastic Neighbor Embedding(t-SNE)分析发现在抗原刺激前后p-TRAC-CAR T与AAV-TRAC-CAR T细胞具有相似的集群模式,见图16。其中,跟T细胞激活相关的标志物CD25和CD69,跟分化相关的标志物如CD45RA、CD45RO、CCR7,颗粒酶B(GZMB),耗竭的标志物PD-1、LAG-3、TIM3的表达量在两种CAR-T细胞接受抗原刺激前后的表达量也基本一致,见图17。
15、p-TRAC-CAR与AAV-TRAC-CAR T细胞在白血病小鼠动物模型中的抗肿瘤能力检测。用NSG小鼠作为实验研究的动物模型,将6-8周的雌性或雄性NSG小鼠进行尾静脉注射50万个NALM6-EGFP-Luciferase肿瘤细胞,3-5天后注射10万个p-TRAC-CAR T细胞或AAV-TRAC-CAR T细胞,然后对小鼠进行活体成像,检测CAR-T细胞对小鼠体内肿瘤的杀伤能力,结果如图18a所示,小鼠的长期生存曲线如图18b所示,结果表明p-TRAC-CAR T细胞与AAV-TRAC-CAR T细胞在白血病小鼠模型体内的抗肿瘤能力没有统计学差异。
实施例4
合成识别插入TCRα位点的Cpf1的crRNA序列,表达纯化蛋白Cpf1,并分离人原代T细胞,分别将AsCpf1-RNP或LbCpf1-RNP电转人原代T细胞,AsCpf1-RNP和LbCpf1-RNP的比例为180pmol crRNA与30pmol的AsCpf1/LbCpf1蛋白,三天后检测TCR的敲除效率,如图19所示,结果显示AsCpf1的敲除效率优于LbCpf1的敲除效率,检测AsCpf1-RNP与pMini-CCS-TRAC-CAR供体DNA模板一起电转后的CAR的插入效率,结果如图20所示,CAR基因的插入效率大约为3.5%。
实施例5
将pMini-CCS-RAB11a-EGFP作为CRISPR-Cas9系统切割后HDR的模板,定点插入EGFP到人原代NK细胞的RAB11a位点。
一、人原代NK细胞的分离和培养
NK细胞无血清培养液配:KBM581培养液+自体血浆(后加)+IL-2(200μ/ml)+庆大霉素(80U/ml)。PBMC(20-30×106)+NK细胞无血清培养液(30ml)+自体血浆(1.5ml)+K562滋养细胞(37℃复苏后PBS清洗一次,350g离心5min,用培养液重悬加入培养瓶),在75cm2培养瓶中混合,置于37℃,5%CO2培养箱中培养。培养3天后离心换液,离心后的细胞沉淀+NK细胞无血清培养液(30ml)+自体血浆(1.5ml)。培养7天后,加液使NK细胞浓度在0.8-1.0×106Cell/ml,血浆按1%添加。11-12天检测NK细胞的富集情况,NK细胞上CD56阳性表达,CD3阴性表达,如图21所示。
二、电转培养11-12天的人原代NK细胞系
将guide RNA和Cas9蛋白体外结合成RNP后,再与pMini-CCS-RAB11a-EGFP质粒载体混合后,最后与人原代NK细胞混合,电转,将EGFP基因定点整合到细胞中。如图22所示,pMini-CCS-RAB11a-EGFP作为CRISPR-Cas9目的基因质粒载体。在人原代NK细胞中的插入效率为3.6%左右。
