Description

一种新型冠状病毒疫苗及其制备方法
技术领域
本发明涉及生物疫苗技术领域，具体而言，涉及一种新型冠状病毒疫苗及其制备方法。
背景技术
新冠肺炎疫情造成了全世界范围内社会和经济的极大损失。该种非典型肺炎被世界卫生组织定名为COVID-19，是由一种新型冠状病毒(SARS-CoV-2,或称2019-nCoV)引起的。针对新型冠状病毒(SARS-CoV-2，或称2019-nCoV)，目前没有特异的治疗方法，只能根据患者的临床状况进行一些对症处理。
近年来mRNA疫苗成为新兴热点，将体外合成的、带有特定抗原蛋白编码序列的mRNA递送进细胞后，使得细胞成为制造抗原蛋白的工厂，引发免疫反应，从而起到疫苗的防护作用。相比传统的灭活、减毒病毒疫苗和DNA疫苗，mRNA疫苗有很多优越性。以mRNA技术来生产疫苗，不仅可以极大缩短研发时间，降低研发成本，实现疫苗的标准化生产，还可以利用mRNA简便的生产工艺随用随制，降低贮存难度。更重要的是，和灭活病毒疫苗比起来，mRNA产品的制剂极大地提高了疫苗的稳定性，因此在产品质量和安全性上，mRNA疫苗具有极大的优势，可以解决传统疫苗行业的痛点，将为疫苗市场带来一场革新。新冠病毒作为RNA病毒，存在极易变异的特点。
新冠病毒作为RNA病毒，存在极易变异的特点。自2020年7月起，变异株相继出现，如包括：Alpha、Beta、Gamma和Delta等。5月31日，世界卫生组织(WHO)宣布，将改用希腊字母命名变异新冠病毒，以避免对最早检测和发现变异病毒的国家造成污名化。依照新命名系统，最早在英国发现的B117变种病毒将改称Alpha变种病毒，最早在南非发现的B1351将改称Beta变种病毒，最早在巴西发现的P1将改称Gamma变种病毒，而最早在印度发现的B1617有两个分支——属于应关注变种的B16172将改称Delta变种病毒，属于待观察变种的B16171将改称Kappa。
研究发现，现有疫苗均是针对2019年的新型冠状病毒SARS-CoV-2进行的抗原设计，对变异株的保护效果出现不同程度的下降。因此，针对变异株具有更好保护效果的新冠疫苗亟待研发。
鉴于此，特提出本发明。

本发明的目的在于提供一种新型冠状病毒疫苗及其制备方法。
本发明是这样实现的：
第一方面，本发明实施例提供了一种分离的mRNA，其编码区核酸序列如SEQ IDNo.2～6中任一项所示，或与如SEQ ID No.2～6中任一项所示的核苷酸序列具有至少99％～80％同一性。

第三方面，本发明实施例提供了如前述实施例所述的新型冠状病毒疫苗的制备方法，其包括：将所述mRNA和递送制剂混合，以形成新型冠状病毒疫苗。
本发明具有以下有益效果：
本发明实施例对编码SARS-CoV-2病毒抗原的mRNA的编码区序列改进，使得制备出来的mRNA疫苗递送到体内可以产生免疫反应，限制提高疫苗对变异株B.1.351.1(Beta株)毒株的保护效率，为变异株B.1.351.1的研究和治疗提供了新的途径。

以下结合实施例对本发明的特征和性能作进一步的详细描述。
实施例1
提供了如表1所示的mRNA，信息见表1所示。
表1 mRNA序列
将表1所示的mRNA转染细胞，检测S全长蛋白在细胞中的表达，结果如图1所示。详细方法如下：转染各mRNA24小时后的HEK293细胞进行裂解，按10μg的总蛋白在SDS-PAGE胶上样，用抗SARS-S1蛋白抗体进行免疫印迹，使用羊抗鼠-HRP二抗进行标记，然后显色。蛋白表达量使用内参b-actin进行标化定量，比较不同mRNA转染细胞后表达的蛋白量差异。未转染mRNA的细胞作为阴性对照。S蛋白全长、S1亚基均可以检测到表达。综合6个不同序列设计的mRNA转染后的蛋白表达效果可得出以下结论：
6个不同序列设计的mRNA转染细胞中的S蛋白表达均有表达，根据分子量大小均可见S蛋白全长和S1亚基这两个条带。
基于SF mRNA序列，S6P mRNA分别在第2400-2800号核苷酸位点上进行了5个核苷酸的优化、在第2910-2920号核苷酸位点上进行了4个核苷酸的优化，相对的翻译后氨基酸序列中6个位点的氨基酸残基被脯氨酸残基取代，具体来说，优化后的S6P mRNA翻译的氨基酸序列在出现了F817P、A882P、A889P、A942P、K986P、V987P共计6个位点的突变。
基于SF mRNA序列，S2P mRNA仅在第2910-2920号核苷酸位点上进行了4个核苷酸的优化，相对的翻译后氨基酸序列中2个位点的氨基酸残基被脯氨酸残基取代，具体来说，优化后的S2P mRNA翻译出的氨基酸序列出现了K986P、V987P共计2个位点的突变。
基于SF mRNA序列，S2P-Beta mRNA和S6P-Beta mRNA分别包含了S2P mRNA和S6PmRNA的优化序列，且增加了在第1200-190号核苷酸位点上进行了4个核苷酸的优化。
含有S6P mRNA和S6P-Beta mRNA转染细胞后，同等情况下的S蛋白含量远远低于其他mRNA转染后的样品，说明S6P mRNA和S6P-Beta mRNA包含的优化位点会导致S蛋白表达量下降，S6P mRNA和S6P-Beta mRNA不适合作为潜在的疫苗选择；SF mRNA、SF-Beta mRNA、S2PmRNA和S2P-Beta mRNA四个序列在HEK293细胞中表达量都较强，这四个mRNA适合做为潜在的疫苗选择。
本实施例还结合其他公开报道对SarS-COV-2的全长S蛋白的其他位点进行了突变，如G614S等，并以SF-Beta mRNA序列为基础设计了相应的mRNA序列，检测mRNA转染细胞后的蛋白表达免疫印迹结果，发现这些突变以及对应的mRNA序列的优化，相比于SF-BetamRNA和S2P-Beta mRNA序列会导致表达量的降低。
参考WOUS21032609、GB2002166、WOUS21016979等公开的SARS-COV-2的全长S蛋白mRNA，以及SF-Beta mRNA、S2P-Beta mRNA、S6P-Beta mRNA的优化方式进行设计，检测mRNA转染细胞后的蛋白表达免疫印迹结果，发现这些突变以及对应的mRNA序列的优化，相比于SF-Beta mRNA和S2P-Beta mRNA序列会导致表达量的降低。
实施例2
实验方案A假病毒病毒株的中和活性实验。
将SF mRNA、S2P-Beta mRNA两种mRNA分别制备成LNP制剂(Dlin-MC3-DMA 50％，cholesterol 29％，DOPC 20％，PEG-DMG 1％。Lipid/mRNA(w/w)＝10:1)，LNP制剂经检测包封率均90％以上，粒径约为70nm。
将所得2组疫苗制剂用于C57小鼠免疫实验，每只小鼠通过后肢外侧大腿肌肉注射5微克(以mRNA计)，在间隔7天后进行二次免疫。首次免疫后14天抽取小鼠血清送第三方实验室进行SARS-CoV-2假病毒中和活性测试。
在96孔板内将小鼠血清按照不同比例稀释后(初始稀释倍数为30)加入可感染SARS-CoV-2假病毒，并同时设置细胞对照和病毒对照，孵育1小时候，加入事先准备好的细胞，于细胞培养箱中培养20～28小时，吸弃一部分上清，加入荧光素酶检测试剂，室温避光反应后，反复吹吸孔内细胞，使细胞充分裂解后，置于化学发光检测仪中读取发光值。确保病毒对照和细胞对照成立的前提下，采用Reed-Muench法计算ID50值。血清对应分组编号及结果如表2所示。
表2 小鼠血清对不同假病毒病毒株的中和活性
由表2可知，SF mRNA和S2P-Beta mRNA两种mRNA制备而成疫苗制剂均可刺激小鼠产生对武汉株(WT)和B.1.351.1(Beta株)株两种假病毒具有中和能力的抗体，但包含S2P-Beta mRNA的疫苗制剂更优，产生的抗体对两种毒株假病毒的中和活性均比SF mRNA强。
实验方案B活病毒病毒株的中和活性实验。
为进一步验证抗原设计中S2P对免疫原性的影响，同时验证小鼠血清对活病毒的中和活性，本实施例增加了一组抗原为S2P的疫苗制剂，同样的免疫方式、免疫程序以及采血时间，对免疫后小鼠血清经ELISA法检测后，根据ELISA结果，随机选取3～4份阳性血清送第三方P3实验室按照新型冠状病毒“微量血清中和试验(CPE法)”技术规范进行操作，同时检测血清对SARS-CoV-2武汉株(WT株)和B.1.351.1(Beta株)株活病毒的中和活性。结果如表3所示。
表3 小鼠血清对不同活病毒病毒株的中和活性
由表3可知，1)SF mRNA、S2P mRNA、S2P-Beta mRNA三种mRNA制备而成疫苗制剂均可刺激小鼠产生对武汉株(WT)和B.1.351.1(Beta株)株两种活病毒具有中和能力的抗体；
2)对比SF mRNA和S2P mRNA的中和活性结果可知，包含SF mRNA的疫苗制剂更优，产生的抗体对两种毒株活病毒的中和活性均比S2P mRNA强。对比SF mRNA和S2P-Beta mRNA的中和活性结果可知，包含S2P-Beta mRNA的疫苗制剂更优，产生的抗体对两种毒株活病毒的中和活性均比S2P mRNA强。
实施方案A的假病毒数据和实验方案B的活病毒中和数据呈现直接对应性。
实施例3
将SF mRNA、SF-Beta mRNA、S2P-Beta mRNA分别和递送制剂制成疫苗，将不同组别mRNA混合物分别制备成LNP制剂(Dlin-MC3-DMA50％，cholesterol 29％，DOPC 20％，PEG-DMG 1％。Lipid/mRNA(w/w)＝10:1)，LNP制剂经检测包封率均90％以上，粒径约为70nm。
将所得三组疫苗制剂用于C57小鼠免疫实验，每只小鼠通过后肢外侧大腿肌肉注射5微克(以mRNA计)，在间隔7天后进行二次免疫。首次免疫后14天抽取小鼠血清送第三方P3实验室按照新型冠状病毒“微量血清中和试验(FRNT法)”技术规范进行操作，同时检测血清对SARS-CoV-2武汉株(WH株)、B.1.351.1(Beta株)株的中和活性。结果如表4所示。
表4 小鼠血清对不同活病毒病毒株的中和活性
实验结果显示：1)含有这3种mRNA的疫苗均能够使小鼠体内产生抗体，该抗体对SARS-CoV-2原始毒株(WT)和变异毒株(Beta毒株)均有中和效果；
2)SF mRNA的疫苗在小鼠体内产生对SARS-CoV-2原始毒株(WT)抗体的抗体滴度高于对SARS-CoV-2变异毒株(Beta毒株)抗体的抗体滴度；SF-Beta mRNA和S2P-Beta mRNA的疫苗在小鼠体内产生对SARS-CoV-2原始毒株(WT)和变异毒株(Beta毒株)抗体的抗体滴度相当；但是综合而言，S2P-Beta mRNA的疫苗针对2个病毒株产生抗体的抗体滴度最优高，可以同时对SARS-CoV-2原始毒株(WT)和变异毒株(Beta毒株)产生较好的中和效果。
实施例4
本实施例提供了一种mRNA核酸疫苗，利用脂质纳米颗粒包裹如SEQ ID NO.1所示的mRNA，其中脂质纳米颗粒按照摩尔百分比计包括Dlin-MC3-DMA 50％、DOPG 10％、胆固醇38.5％和PEG-DMG 1.5％。
制备方法如下：
(a)将如SEQ ID NO.1所示的mRNA溶解于pH4的柠檬酸盐缓冲液，将浓度调整为0.1mg/ml，得到水相。
(b)按照配方量将Dlin-MC3-DMA、DOPG、胆固醇和PEG-DMG按照配方量溶解于无水乙醇，将有机相中的脂质成分的浓度调整至6mg/mL，得到有机相。
(c)将步骤(a)的水相和步骤(b)的有机相按照1:3的体积比，使用微流控设备，按照12mL/min的流速混合，混合液立刻用pH7.4的PBS溶液稀释100倍，并使用切向流过滤(TFF)除去溶液中乙醇成分，然后浓缩至体系中的mRNA的浓度为100μg/ml，得到包裹如SEQID NO.1所示的mRNA的脂质纳米颗粒。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
