Description
技术领域
本发明涉及生物技术领域,具体是指一种通过CRISPR/Cas9系统快速筛选重组鸡痘病毒的方法及其应用。
背景技术
鸡痘病毒基因组的高保守区的非复制区域可以整合外源DNA,已经成为普遍的表达载体,在病毒分子生物学、载体疫苗生产等领域得到广泛应用。鸡痘病毒载体疫苗不仅能预防鸡痘的发生,而且还能通过插入其他病原的保护性抗原基因,诱导表达插入基因提高相对应病原的免疫抵抗力。由于重组鸡痘病毒所表达的外源基因在机体内随载体病毒的复制而表达,与灭活疫苗相比,免疫剂量小,接种方法简单,免疫一次能获得长期的免疫效果,很大程度上降低了生产成本。目前,国内外已有多种表达外源基因的重组鸡痘疫苗得到生产应用。
CRISPR/Cas9是继第一代人工核酸内切酶—锌指核酸酶(zinc-fingernucleases,ZFN)和第二代人工核酸内切酶—转录激活因子样效应因子核酸酶(transcription activator-like effectornucleases,TALEN)后产生的第三代人工核酸内切酶,可用于各种复杂基因组的定点修饰,修饰类型包括基因的定点突变、基因定点插入、多个位点同时突变和小片段的缺失(Tremblay JP.The CRISPR system can corrector modify the expression of genes responsible for hereditary diseases.Med Sci(Paris)2015;31(11):1014-22.)(Spencer NY,Yan Z,Cong L,Zhang Y,Engelhardt JF,Stanton RC.Definitive localization of intracellular proteins:Novel approachusing CRISPR-Cas9genome editing,with glucose 6-phosphate dehydrogenase as amodel.Anal Biochem 2016;494:55-67.)。目前,CRISPR/Cas9已成功应用于小鼠、斑马鱼和人类细胞甚至细菌的基因组精确编辑(Li JF,Zhang D,Sheen J.Targeted plant genomeediting via the CRISPR/Cas9technology.Methods Mol Biol 2015;1284:239-55.)。由于CRISPR/Cas9技术具有突变效率高、制作简单而且成本低廉等优势,已被公认为是一种具有广阔应用前景的基因组定点改造分子工具。
CRISPR/Cas9系统的工作原理是crRNA(CRISPR-derived RNA)通过碱基配对与tracrRNA(trans-activating RNA)结合形成tracrRNA/crRNA复合物,此复合物引导核酸酶Cas9蛋白在与crRNA配对的序列靶位点剪切双链DNA。而通过人工设计这两种RNA,可以改造形成具有引导作用的sgRNA(short guide RNA),足以引导Cas9对DNA的定点切割。目前,有报道显示通过CRISPR/Cas9对痘病毒进行切割抑制病毒复制,但在提高重组鸡痘病毒筛选方面还没有报道(王娇娇,张新敏,倪爱民等CRISPR/Cas9切割痘病毒DNA抑制病毒复制中国细胞生物学学报Chinese Journal of Cell Biology 2016,38(4))。在重组鸡痘病毒的构建过程中,目前使用的方法是使用脂质体或电转等方法将含有表达外源基因的质粒与鸡痘病毒共转染,再通过报告基团EGFP、lacz进行空斑筛选,要经过十几代的筛选才能得到纯的重组鸡痘病毒,生产周期长。足见,现有技术有待改善。

2.4 阳性质粒判断
将抽提的质粒使用试剂盒中引物dGuide-it Sequencing Primer 1(序列NO:8)送测序公司测序,根据测序所得序列寻找CCGG碱基后面20个碱基是否为序列:AATGGACTATCATATGCTTACCGT,若是则为阳性质粒,即为表达sgRNA的CRISPR/Cas9表达质粒。
2.5 将表达FADV4 fiber2重组鸡痘病毒转移质粒pMD22-TYB-lacz-F4、表达sgRNA的CRISPR/Cas9表达质粒与鸡痘病毒共转染CEF细胞,同时设置单独的转移质粒pMD22-TYB-lacz-F4与鸡痘病毒共转染CEF细胞作为对照,具体操作如下:
先制备好CEF细胞:①将选好的两枚9-10日龄的发育良好的SPF胚用5%的碘棉消毒蛋壳气室部位,再用酒精棉脱碘;②无菌取出鸡胚,放入灭菌的玻璃皿内,用PH7.2的PBS冲洗一次,去头,四肢和内脏;③再用PH7.2的PBS冲洗两次;④用手术剪剪成小块(2-3mm),用PH7.2的PBS冲洗两次;⑤约加20ml0.25%胰酶溶液,37℃消化15min,期间5min轻摇一次;⑥消化结束,将细胞消化倒入带6-8层纱布的100ml烧杯中过滤;⑦将过滤液2000rpm离心5min,弃去上清液,将细胞用含10%FCS的DMEM培养基溶解;⑧用适当体积接于细胞培养皿中,37℃,5%CO2培养箱培养;
待CEF细胞长满单层后,接种鸡痘病毒液,37℃,5%CO2培养箱孵育2h,去病毒液,洗两遍,按照Lipofectamine 2000试剂使用说明方法将质粒pMD22-TYB-lacz-F4和CRISPR/Cas9表达质粒以1:1比例与鸡痘病毒共转染CEF细胞,同时设单独的质粒pMD22-TYB-lacz-F4与鸡痘病毒共转染CEF细胞,待细胞产生80%病变时收集细胞,反复冻融三次,收集重组病毒液。
2.6 重组鸡痘病毒的纯化
将上述收集的病毒液用X-gal进行蓝白斑筛选纯化,挑取蓝斑,进行数代纯化直至出现的空斑全部为蓝斑,如图2所示;同时抽提纯化的不同代次的病毒液DNA,用鸡痘病毒同源臂上引物TYB-JC-F/R(见表1)及FADV4 fiber2引物F4-fiber2-F/R(见表1)分别对样本进行PCR检测,结果如图3、4所示。
图3为引物TYB-JC-F/R PCR扩增图:编号8为以转移载体pMD22-TYB-lacz-F4为模板的阳性对照,片段大小为5315bp,编号9为以FPV抽提DNA为模板的对照,大小为703bp,若是PCR结果只出现5315bp条带,则说明病毒为rFPV-FADV4 fiber2重组病毒,若是只出现703bp片段,则说明病毒为FPV病毒,若同时出现两条带则说明病毒为rFPV-FADV4 fiber2重组病毒与FPV病毒混合病毒,rFPV-FADV4 fiber2重组病毒不纯,编号1至4为单独的质粒pMD22-TYB-lacz-F4与鸡痘病毒共转染CEF细胞纯化第4、7、9、12代抽提的DNA,可看出重组病毒纯化至12代才纯化好,编号5、6、7为质粒pMD22-TYB-lacz-F4和CRISPR/Cas9表达质粒以1:1比例与鸡痘病毒共转染CEF细胞纯化第3、4、5代后抽提DNA,由此结果可看出使用CRISPR/Cas9表达系统从第3代开始就只有5315bp出有一条条带,及已纯化,可见本发明方法筛选的效率要高很多,节省了时间。
图4为FADV4 fiber2引物F4-fiber2-F/RPCR检测结果图:编号1为单独的质粒pMD22-TYB-lacz-F4与鸡痘病毒共转染CEF细胞纯化第7代抽提的DNA,编号2为质粒pMD22-TYB-lacz-F4和CRISPR/Cas9表达质粒以1:1比例与鸡痘病毒共转染CEF细胞纯化第4代抽提的DNA,从PCR结果可看出FADV4 fiber2基因已重组到FPV病毒中。
实施例3本发明方法筛选重组鸡痘病毒的方法在制备抗鸡4型腺病毒FPV载体疫苗中的应用
按照图1所示构建好rFPV-FADV4 fiber2转移载体,将构建好的载体与上述构建的表达sgRNA的CRISPR/Cas9质粒按1:1比例共转染已感染鸡痘病毒的CEF细胞,培养,通过X-GAL进行蓝白斑筛选,经过四代筛选得到了纯化好的rFPV-FADV4 fiber2病毒,将其在CEF细胞上进行数次传代,收集好病毒液,作为制备抗鸡4型腺病毒FPV载体疫苗提供病毒液,将所收集的病毒液按常规操作制备方法操作,制得抗鸡4型腺病毒FPV载体疫苗。
表达鸡4型腺病毒fiber2基因的重组鸡痘病毒表达效果的验证:
将上述病毒液中的表达鸡4型腺病毒fiber2基因的重组鸡痘病毒(rFPV-FADV4fiber2)进行多次筛选纯化,将纯化得到的rFPV-FADV4 fiber2接种于用24孔板培养的CEF细胞中,置于37℃、5%的二氧化碳培养箱培养,待出现明显病变后,用PBS洗两遍;冷甲醇固定,PBS洗三遍;加1%BSA封闭1h,用PBS洗三遍;加入1:100稀释的鸡抗FADV4的一抗37℃孵育2h,用PBST洗三遍;再加入1∶200稀释的兔抗鸡IgG-FITC荧光二抗,室温孵育1h,PBST洗三遍;置于倒置荧光显微镜下观察结果,同时以正常CEF细胞及感染了鸡痘病毒的CEF细胞经同样的方式处理,作为对照。结果如图5-7所示,可以看出只有感染了rFPV-FADV4 fiber2的CEF细胞上出现了特异性的绿色荧光,表明重组鸡痘病毒rFPV-FADV4 fiber2感染了CEF细胞后有效的表达了FADV4的fiber2抗原。
抗鸡4型腺病毒FPV载体疫苗临床试验验证
本发明还验证了重组鸡痘病毒rFPV-FADV4 fiber2(纯化得到的疫苗)在动物体内的免疫效果,结果显示该重组病毒在动物体内可产生良好的免疫效果。
用重组病毒(rFPV-FADV4 fiber2)(5×105PFU/羽)经翅皮下注射接种于10天龄的SPF鸡上,同时设空白组、免疫某公司灭活疫苗组做对照,分别于免疫前、免后三周采血,通过ELISA方法检测机体抗体水平变化,步骤如下:用包被缓冲液将表达FADV4 fiber2的蛋白稀释至3μg/ml,每孔加100ul,包被于96孔板中37℃2h,1%BSA,37℃封闭1h,加入所采的稀释了200倍的血清,37℃孵育2h,用PBST洗三遍,每次洗3min,再加入羊抗鸡HRP酶标记二抗37℃孵育1h,用PBST洗三遍,每次洗3min,加底物显色,37℃20min,最后加终止液终止,将板置于酶标仪中,在OD450下读数;结果如下:免疫前整体抗体水平OD值为0.31,免疫后三周,空白组平均OD值为0.27,某公司灭活疫苗为0.75,rFPV-FADV4 fiber2重组病毒为0.77,结果显示该重组病毒在动物体内可产生良好免疫应答。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
