具体实施方式
为帮助了解本公开的目的、特征及功效,提供用于详细描述本公开的实施例及附图。
疫苗候选物的表达
首先,设计四个疫苗候选物的DNA序列,所述DNA序列分别编码重组蛋白RBD-Fc、重组蛋白S2△TM-Fc、重组蛋白S1-Fc和重组蛋白S△TM-Fc。图13示出RBD-Fc的DNA序列。图14示出S2△TM-Fc的DNA序列。图15示出S1-Fc的DNA序列。图16示出S△TM-Fc的DNA序列。
疫苗候选物是根据SARS-CoV-2棘蛋白(spike protein)(存取编号:NC_045512)的氨基酸序列所设计的。在此,RBD-Fc代表SARS-CoV-2的棘蛋白的受体结合域与IgG1重链恒定区2和重链恒定区3(Fc蛋白)融合,RBD-Fc的氨基酸序列在图1中示出;S2△TM-Fc代表SARS-CoV-2的棘蛋白的跨膜蛋白缺失的S2次单元与Fc蛋白融合,S2△TM-Fc的氨基酸序列在图2中示出;S1-Fc代表SARS-CoV-2的棘蛋白的S1次单元与Fc蛋白融合,S1-Fc的氨基酸序列在图3中示出;S△TM-Fc代表SARS-CoV-2的跨膜蛋白缺失的棘蛋白与Fc蛋白融合,S△TM-Fc的氨基酸序列在图4中示出。基于疫苗生产的目的,所有疫苗候选物的构建体皆与分泌信号肽(secreted signal peptide)融合,分泌信号肽位于重组蛋白的N端,Fc序列位于重组蛋白的C端。分泌信号肽的氨基酸序列在图5中示出。然而,在其他实施例中,分泌信号肽并非必要。
其次,上述四个疫苗候选物的DNA序列分别转殖到pFastBac 1载体中。在其他实施例中,所述载体可以选自痘疮病毒(vaccinia virus)、禽痘病毒(avipoxvirus)、腺病毒(adenovirus)、甲病毒(alphavirus)、棒状病毒(rhabdovirus)、疱疹病毒(herpesvirus)或其他已知适合的载体系统。
四个分别含有各个上述疫苗候选物DNA序列的pFastBac 1载体被转化(transformed)到大肠杆菌菌株DH10Bac中,用以产生含有上述四个疫苗候选物的DNA序列的重组Bacmid DNA。重组Bacmid DNA通过PCR分析鉴别。如图6所示,M表示分子量标记,数字“1”、“2”及“3”表示大肠杆菌菌株的编号,上述重组Bacmid DNA由上述大肠杆菌菌株中获得,RBD-Fc、S2△TM-Fc、S1-Fc和S△TM-Fc的理论重组Bacmid DNA大小分别为3,809bps、4,700bps、5,159bps和6,743bps。经确定的RBD-Fc、S2△TM-Fc、S1-Fc和S△TM-Fc的重组Bacmid DNA大小则分别为3,900bps、4,800bps、5,200bps和6,800bps,其与上述理论重组Bacmid DNA大小相对应。上述重组Bacmid DNA转化及PCR分析是根据Bac-to-BacTM杆状病毒表达系统用户指引(Bac-to-BacTMBaculovirus Expression System USER GUIDE)进行。
接着,分别将含有各个上述四个疫苗候选物的DNA序列的重组Bacmid DNA转染(transfected)到秋行军虫(S.frugiperda)细胞中(sf9细胞)用于杆状病毒生产。杆状病毒由DNA序列鉴别。上述重组Bacmid DNA的转染是根据Bac-to-BacTM杆状病毒表达系统用户指引进行。
最后,以分别具有0.1、0.001和0.0001的病毒感染复数(multiplicity ofinfection,MOI)的含有上述四个疫苗候选物DNA序列的杆状病毒感染sf9细胞持续五天,被病毒感染的细胞增生趋势于图7中示出。在感染后的第三天、第四天及第五天的时间点,收集被感染的sf9细胞以确认疫苗候选物的表达量,通过蛋白质印迹法检测在被感染的sf9细胞中合成的蛋白,结果示于图8,通过蛋白质基准点位置和以千道尔顿(kilodaltons,kda)表示的蛋白质大小指出,55kda(A:RBD-Fc)的重组蛋白、110kda(B:S2△TM-Fc)的重组蛋白、130kda(C:S1-Fc)的重组蛋白和170kda(D:S△TM-Fc)的重组蛋白部分为细胞中主要合成的蛋白。上述的蛋白质印迹法分析根据参考文献“A Guide to Polyacrylamide GelElectrophoresis and detection(Bio-Rad)”进行。
疫苗候选物的生产
准备sf9细胞,sf9细胞在insect-XPRESS无蛋白培养基(insect-XPRESS Protein-free media(Lonza Ltd))中,27℃环境下,生长到3.5~5×106细胞/mL的密度。sf9细胞被具有0.1~0.0001的病毒感染复数(MOI)的含有上述四个疫苗候选物DNA序列的杆状病毒表达载体感染,用以生产疫苗候选物。在感染sf9细胞期间,疫苗候选物在杆状病毒多角体蛋白启动子的转录控制下生产疫苗候选物。sf9细胞在感染后72~96小时通过以6,000x g离心15分钟被收取。sf9细胞的悬浮液储存在4℃环境中。
疫苗候选物RBD-Fc的纯化
在此实施例中,将纯化RBD-Fc,RBD-Fc为非变性的且适于作为将进行蛋白A亲和性层析(protein A affinity chromatography)的用于人类用途的冠状病毒疫苗成分。将使用下列流程来从被重组杆状病毒感染的sf9细胞中纯化出RBD-Fc。
根据上述“疫苗候选物的表达”流程,准备2L的含有RBD-Fc的受感染sf9细胞的培养液,被感染的sf9细胞的初始细胞浓度为1.0x 106细胞/mL,sf9细胞接着被感染持续三天,直到sf9细胞中的被感染细胞浓度达到4.0x 106细胞/mL(存活率40-60%,MOI=0.1)。受感染sf9细胞的培养液以9,000x g离心20分钟,以获得上清,以过滤器(0.22μm的孔径)过滤所述上清以获得样本液体。
准备填有20mL蛋白A树脂(Eshmuno A,Merck Millipore)的pharmacia XK 16/40管柱,并将其安装到AKTA纯化层析系统上。上述样本液体以20mL/分钟的流速(精确度(PreC):0.30Mpa)加入到管柱中,收集流经的液体。在将上述样本液体倒入到管柱中后,以PBS(pH 7.3)进一步清洗管柱,直到清洗液体在280nm的UV吸光值返回到基线。流经管柱的清洗液体也被收集。在清洗管柱之后,将作为洗脱液的柠檬酸溶液(0.3M)倒入管柱中以获得与蛋白A结合的含有RBD-Fc的洗脱液。
由于杂质蛋白也会流经管柱进到洗脱液中,因此将先前含有RBD-Fc的洗脱液再一次利用大约5倍管柱体积的100mM柠檬酸(pH 3.0)从蛋白A树脂管柱中洗脱出,并且所述洗脱液以1M Tris-HCl(pH 9.0)中和。样本液体、流经液体、清洗液体和洗脱液通过SDS-PAGE分析如下。将样本液体、流经液体、清洗液体和洗脱液中的蛋白置于存在有2%的十二烷基硫酸钠和5%的β-巯基乙醇的沸水浴中持续10分钟以打断(disrupte)蛋白质,接着通过SDS-PAGE(存在有0.1%SDS的10%的聚丙烯酰胺凝胶)分析样本液体、流经液体、清洗液体和洗脱液中的蛋白,最后以考马斯蓝(Coomassie blue)染色。SDS-PAGE分析是根据参考文献“A Guide to Polyacrylamide Gel Electrophoresis and detection(Bio-Rad)”进行。
S2△TM-Fc、S1-Fc和S△TM-Fc的纯化以与RBD-Fc纯化流程相同的流程进行。
四个疫苗候选物的纯化结果如图9所示。纯化的疫苗候选物通过上述流程获得。
在其他实施例中,其他已知的蛋白质纯化技术也可以应用于纯化上述疫苗候选物。
来自于已免疫化的小鼠其针对SARS-CoV-2病毒的抗血清的病毒蚀斑减少溶斑抑制中和试验(plaque reduction neutralization test,PRNT)
首先,准备十二组C57BL/6小鼠(7周大,雌性,重量为18~22克),每组含有十只小鼠,通过肌肉内注射20μg的疫苗候选物(溶于50μl的PBS)使五组小鼠被免疫化三次;通过肌肉内注射20μg的疫苗候选物(溶于50μl的PBS,PBS中含有作为佐剂的氢氧化铝)使五组小鼠被免疫化三次;一组小鼠被肌肉内注射含有氢氧化铝的50μl的PBS三次;一组小鼠仅被肌肉内注射50μl的PBS三次。上述免疫化条件在表1中列出。
表1
Figure BDA0003044954700000091
*佐剂的量为500μg/剂
其次,在免疫化的时间点,第1、6及7组的小鼠被采血以检测中和抗体效价。结果示出于图10中,被施用RBD-Fc和佐剂的第7组小鼠具有较高抗体效价。
最后,将十二组单层vero E6细胞预先接种于一24孔板中的12孔内作为实验组。将获自上述被免疫化三次的12组小鼠的0.1mL的测试血清分别与100PFU/0.1mL的SARS-CoV-2病毒(由台湾大学医学院医学检验暨生物技术学系Sui-Yuan Chang教授提供)混合,并且于37℃培养60分钟。接着,十二组SARS-CoV-2病毒和测试血清的混合物分别加入十二组实验组中。同时,设立用于各个检验的十二组阳性对照孔(vero E6细胞与100PFU的SARS-CoV-2病毒在不加入上述血清的条件下于37℃环境中共同培养60分钟)作为阳性对照组,以确定上述细胞单层的感染度。随后,去除十二个实验组和十二个阳性对照组中的培养基,接着将覆盖培养基(overlay medium)加入十二个实验组和十二个阳性对照组中。具有十二个实验组和十二个阳性对照组的24孔板在37℃、5%的CO2中持续培养六天,并且在第六天计算病毒蚀斑。病毒蚀斑减少中和试验的结果示于图11中,其证实当实验组含有与Fc蛋白融合的RBD结构域时(第1、3-5、7和9-10组),可以有效地诱导针对SARS-CoV-2病毒的中和抗体产生,含有与Fc蛋白融合的RBD结构域及佐剂的实验组的功效更好,并且与Fc蛋白融合的S2△TM-Fc及佐剂的组合也可以诱导针对SARS-CoV-2病毒的中和抗体产生。
此外,用于SARS-CoV-2的SARS-CoV-2重组蛋白片段也可以被设计成与RBD、S1蛋白、S2蛋白或棘蛋白具有至少80%、81%、82%、83%、84%、85%、86%、87%、88%、89%、90%、91%、92%、93%、94%、95%、96%、97%、98%或99%的相似度;用于SARS-CoV-2的Fc蛋白片段也可以被设计成具有至少六个氨基酸的长度,并且较佳地具有在12至18个氨基酸之间的长度。Fc蛋白片段的长度。Fc蛋白片段的长度可以是6、7、8、9、10、11、12、13、14、15、16、17或18个氨基酸。
图12示出SARS-CoV-2的核壳磷蛋白(nucleocapsid phosphoprotein protein)、包膜蛋白(envelope protein)和膜蛋白(membrane protein)。为了新冠肺炎疫苗的应用,SARS-CoV-2的核壳磷蛋白、包膜蛋白和膜蛋白也能够被设计成新冠肺炎疫苗的一部分,即SARS-CoV-2的核壳磷蛋白、包膜蛋白和膜蛋白可以与上述疫苗候选物融合。
如在本文中所使用的,两个氨基酸序列之间的“同源性百分比(percenthomology)”是使用在参考文献(Karlin and Altschul,Proc,Natl.Acad.Sci.USA87:2264-2268,1990)中描述的,并且如参考文献(Karlin and Altschul,Proc,Natl.Acad.Sci.USA90:5873-5877,1993)进行修改的算法来确定的。这种算法整合于参考文献(Altschul etal.,J.Mol.Biol.215:403-410,1990)的NBLAST和XBLAST程序中。BLAST蛋白质搜索以XBLAST程序执行,分数=50,字长度=3,以获得与参考多肽同源的氨基酸序列。为了用于比对目的的间隔对准,使用在参考文献(Altschul et al.,Nucleic Acids Res.25:3389-3402,1997)中描述的间隔的BLAST。当使用NBLAST和XBLAST程序时,使用各别程序的除错参数(例如,XBLAST和NBLAST)。见www.ncbi.nlm.nih.gov网站。
如上所述,与Fc蛋白融合的SARS-CoV-2重组蛋白诱导针对SARS-CoV-2病毒的中和抗体产生,并且其可以被用于作为针对新冠肺炎的疫苗(COVID-19)。
当本公开已经以具体实施例的方式描述,本领域技术人员可以在不脱离在权利要求中说明的本公开的范围和精神情况下,进行多种修改和变体。
