Description
技术领域
本发明涉及免疫学和分子病毒学技术领域,具体地说,涉及一种新型冠状病毒及其突变体的单克隆抗体及其应用。
背景技术
严重急性呼吸综合征冠状病毒2(SARS-CoV-2),即新型冠状病毒,传播快速、广泛,致死率高,对公众的生命和健康造成重大威胁。
与此同时,以SARS-CoV-2的Alpha、Beta、Gamma和Delta为代表的各种变种快速传播,本领域正努力应对新的病毒变种。之前已经报道了针对SARS-CoV-2的S蛋白及其RBD的研究,最近的几项研究也已经确定了一些可以逃逸某些单克隆抗体的病毒突变,这些突变发生在中和抗体与病毒结合的关键位置,从而影响中和抗体的效果。
SARS-CoV-2是导致新型冠状病毒肺炎(COVID-19)的病原体,是一种具有囊膜结构的单链正链RNA病毒,它与重症急性呼吸综合征冠状病毒(SARS-CoV)以及中东呼吸综合征冠状病毒(MERS-CoV)同属冠状病毒科。该病毒表面的刺突蛋白(Spike,S蛋白)在感染宿主的过程中,通过结合宿主细胞受体血管紧张素转换酶2(ACE2),从而触发病毒膜与宿主细胞膜融合机制,导致宿主细胞感染病毒。其中S蛋白分为S1和S2两部分,已有研究证实S1的C端(CTD)的受体结合结构域(RBD)与ACE2结合,从而介导膜融合过程。
迄今为止,中和抗体已被证明是治疗病毒性疾病的有效方法。目前已经上市的治疗和预防病毒感染的药物有预防小儿呼吸道合胞病毒(RSV)感染的帕利珠单抗(Synagis),治疗HIV感染的艾巴利珠单抗(Trogarzo),以及用于狂犬病毒暴露后预防的Rabishield。此外,还有多种针对不同病毒的单抗处于临床研究的不同阶段(https://clinicaltrials.gov/)。抗体主要通过两方面起作用。一方面,具有中和活性的抗体可通过结合病毒囊膜蛋白,阻断病毒与细胞受体的结合,从而阻断病毒感染。另一方面,抗体依赖的细胞介导的细胞毒性作用(ADCC)和补体依赖的细胞毒性作用(CDC)可募集巨噬细胞或是补体等免疫细胞和免疫分子,从而清除游离的病毒以及被感染的细胞。
因此,筛选出具有更高亲和力并且能够对各种突变体表现出中和活性的单克隆抗体是紧迫而重要的,它在提供一种新的有效预防和治疗新型冠状病毒感染的手段的同时,还可以更广泛的保护公众的生命和健康安全。
发明内容
在本发明中,除非另有说明,否则其所使用的科学和技术名词具有本领域技术人员所通常理解的含义。并且,本发明中(若有涉及)所用的细胞培养、分子遗传学、核酸化学、免疫学实验室操作步骤均为相应领域内广泛使用的常规步骤。同时,为了更好地理解本发明,下面提供相关术语的定义和解释。
如本发明中所使用的,术语“抗体”是指,通常由两对多肽链(每对具有一条“轻”(L)链和一条“重”(H)链)组成的免疫球蛋白分子。抗体轻链可分类为κ和λ轻链。重链可分类为μ、δ、γ、α或ε,并且分别将抗体的同种型定义为IgM、IgD、IgG、IgA和IgE。在轻链和重链内,可变区和恒定区通过大约12或更多个氨基酸的“J”区连接,重链还包含大约3个或更多个氨基酸的“D”区。各重链由重链可变区(VH)和重链恒定区(CH)组成。重链恒定区由3个结构域(CH1、CH2和CH3)组成。各轻链由轻链可变区(VL)和轻链恒定区(CL)组成。轻链恒定区由一个结构域CL组成。抗体的恒定区可介导免疫球蛋白与宿主组织或因子,包括免疫系统的各种细胞(例如,效应细胞)和经典补体系统的第一组分(C1q)的结合。VH和VL区还可被细分为具有高变性的区域(称为互补决定区(CDR)),其间散布有较保守的称为构架区(FR)的区域。各VH和VL由按下列顺序:FR1、CDR1、FR2、CDR2、FR3、CDR3、FR4从氨基末端至羧基末端排列的3个CDR和4个FR组成。各重链/轻链对的可变区(VH和VL)分别形成抗体结合部位。氨基酸至各区域或结构域的分配遵循Kabat Sequences of Proteins of ImmunologicalInterest(National Institutes of Health,Bethesda,Md.(1987and 1991)),或Chothia&Lesk(1987)J.Mol.Biol.196:901-917;Chothia等人(1989)Nature 342:878-883的定义。术语“抗体”不受任何特定的产生抗体的方法限制。例如,其包括,重组抗体、单克隆抗体和多克隆抗体。抗体可以是不同同种型的抗体,例如,IgG(例如,IgG1,IgG2,IgG3或IgG4亚型),IgA1,IgA2,IgD,IgE或IgM抗体。
如本发明中所使用的,术语抗体的“抗原结合片段”是指包含全长抗体的片段的多肽,其保持特异性结合全长抗体所结合的相同抗原的能力,和/或与全长抗体竞争对抗原的特异性结合,其也被称为“抗原结合部分”。通常参见,Fundamental Immunology,Ch.7(Paul,W.,ed.,第2版,Raven Press,N.Y.(1989),其以其全文通过引用合并入本发明,用于所有目的。可通过重组DNA技术或通过完整抗体的酶促或化学断裂产生抗体的抗原结合片段。在一些情况下,抗原结合片段包括Fab、Fab'、F(ab')2、Fd、Fv、dAb和互补决定区(CDR)片段、单链抗体(例如,scFv)、嵌合抗体、双抗体(diabody)和这样的多肽,其包含足以赋予多肽特异性抗原结合能力的抗体的至少一部分。
在一些情况下,抗体的抗原结合片段是单链抗体(例如,scFv),其中VL和VH结构域通过使其能够产生为单个多肽链的连接体配对形成单价分子(参见,例如,Bird等人,Science 242:423 426(1988)和Huston等人,Proc.Natl.Acad.Sci.USA 85:5879 5883(1988))。此类scFv分子可具有一般结构:NH2-VL-接头-VH-COOH或NH2-VH-接头-VL-COOH。合适的现有技术接头由重复的GGGGS氨基酸序列或其变体组成。例如,可使用具有氨基酸序列(GGGGS)4的接头,但也可使用其变体(Holliger等人(1993),Proc.Natl.Acad.Sci.USA 90:6444-6448)。可用于本发明的其他接头由Alfthan等人(1995),Protein Eng.8:725-731,Choi等人(2001),Eur.J.Immunol.31:94-106,Hu等人(1996),Cancer Res.56:3055-3061,Kipriyanov等人(1999),J.Mol.Biol.293:41-56和Roovers等人(2001),Cancer Immunol.描述。
在一些情况下,抗体的抗原结合片段是双抗体,即,双价抗体,其中VH和VL结构域在单个多肽链上表达,但使用太短的连接体以致不允许在相同链的两个结构域之间配对,从而迫使结构域与另一条链的互补结构域配对并且产生两个抗原结合部位(参见,例如,Holliger P.等人,Proc.Natl.Acad.Sci.USA 90:6444 6448(1993),和Poljak R.J.等人,Structure 2:1121 1123(1994))。
可使用本领域技术人员已知的常规技术(例如,重组DNA技术或酶促或化学断裂法)从给定的抗体(例如本发明提供的单克隆抗体9K)获得抗体的抗原结合片段(例如,上述抗体片段),并且以与用于完整抗体的方式相同的方式就特异性筛选抗体的抗原结合片段。
在本发明中,除非上下文明确指出,否则当提及术语“抗体”时,其不仅包括完整抗体,而且包括抗体的抗原结合片段。
如本发明中所使用的,术语“单克隆抗体”是指,来自一群高度同源的抗体分子中的一个抗体或抗体的一个片段,也即,除可能自发出现的自然突变外,一群完全相同的抗体分子。单抗对抗原上的单一表位具有高特异性。多克隆抗体是相对于单克隆抗体而言的,其通常包含至少2种或更多种的不同抗体,这些不同的抗体通常识别抗原上的不同表位。单克隆抗体通常可采用Kohler等首次报道的杂交瘤技术获得(Nature,256:495,1975),但也可采用重组DNA技术获得(如参见Journal of virological methods,2009,158(1-2):171-179)。
如本发明中所使用的,“中和抗体”是指,能清除或显著降低目标病毒的毒力(例如,感染细胞的能力)的抗体或抗体片段。
如本发明中所使用的,术语“载体(vector)”是指,可将多聚核苷酸插入其中的一种核酸运载工具。当载体能使插入的多核苷酸编码的蛋白获得表达时,载体称为表达载体。载体可以通过转化,转导或者转染导入宿主细胞,使其携带的遗传物质元件在宿主细胞中获得表达。载体是本领域技术人员公知的,包括但不限于:质粒;噬菌粒;人工染色体,例如酵母人工染色体(YAC)、细菌人工染色体(BAC)或P1来源的人工染色体(PAC);噬菌体如λ噬菌体或M13噬菌体及动物病毒等。可用作载体的动物病毒包括但不限于,逆转录酶病毒(包括慢病毒)、腺病毒、腺相关病毒、疱疹病毒(如单纯疱疹病毒)、痘病毒、杆状病毒、乳头瘤病毒、乳头多瘤空泡病毒(如SV40)。一种载体可以含有多种控制表达的元件,包括但不限于,启动子序列、转录起始序列、增强子序列、选择元件及报告基因。另外,载体还可含有复制起始位点。
如本发明中所使用的,术语“宿主细胞”是指,可用于导入载体的细胞,其包括但不限于,如大肠杆菌或枯草芽孢杆菌等的原核细胞,如酵母细胞或曲霉菌等的真菌细胞,如S2果蝇细胞或Sf9等的昆虫细胞,或者如纤维原细胞,CHO细胞,COS细胞,NSO细胞,HeLa细胞,BHK细胞,HEK293细胞或人细胞等的动物细胞。
如本发明中使用的,术语“特异性结合”是指,两分子间的非随机的结合反应,如抗体和其所针对的抗原之间的反应。在某些实施方式中,特异性结合某抗原的抗体(或对某抗原具有特异性的抗体)是指,抗体以小于大约10-5M,例如小于大约10-6M、10-7M、10-8M、10-9M或10-10M或更小的亲和力(KD)结合该抗原。
如本发明中所使用的,术语“KD”是指特定抗体-抗原相互作用的解离平衡常数,其用于描述抗体与抗原之间的结合能力。平衡解离常数越小,抗体-抗原结合越紧密,抗体与抗原之间的亲和力越高。通常,抗体(例如,本发明的单克隆抗体9K)以小于大约10-5M,例如小于大约10-6M、10-7M、10-8M、10-9M或10-10M或更小的解离平衡常数(KD)结合抗原(例如,新型冠状病毒S蛋白的RBD),此数值使用表面等离子体共振术(SPR)在BIACORE 8K设备中测定。
在本发明中,氨基酸通常用本领域公知的单字母或三字母缩写来表示。例如,丙氨酸可用A或Ala表示。
如本发明中所使用的,术语“中和活性”是指抗体或抗体片段具有与病毒上的抗原蛋白相结合,从而阻止病毒感染细胞和/或病毒子代的成熟和/或病毒子代的释放的功能活性,具有中和活性的抗体或抗体片段可以阻止病毒的扩增,从而抑制或消除病毒的感染。
如本发明中所使用的,术语“新型冠状病毒”和“SARS-CoV-2”是指,国际病毒分类委员会(International Committee on Taxonomy of Viruses,ICTV)正式分类名的严重急性呼吸综合征冠状病毒2(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2),二者具有相同的含义,可互换使用。
如本发明中所使用的,术语“新型冠状病毒肺炎”和“COVID-19”是指,因SARS-CoV-2感染而导致的肺炎,二者具有相同的含义,可互换使用。
针对现有技术的问题,本发明的目的在于提供一种与新型冠状病毒及其各突变株亲和力高的单克隆抗体及其应用。
为了实现该目的,本发明经过大量的实验研究后发现了一种抗体,其能够特异性识别并靶向新型冠状病毒及几种主要流行突变株的S蛋白,特别是S蛋白的受体结合结构域(RBD),并且能够阻断S蛋白的RBD与细胞受体血管紧张素转换酶2(ACE2)的结合,显示出了高效的中和病毒的能力。因此,本发明的抗体特别适合用于诊断、预防和治疗新型冠状病毒以及几种流行突变株感染或与新型冠状病毒感染相关的疾病(例如新型冠状病毒肺炎)。
