发明详述
定义
除非另有指示或定义,否则所有所用术语均具有本领域中的通常含义,该含义将为本领域技术人员所了解。参考例如标准手册,如Sambrook et a1.,“Molecular Cloning:A Laboratory Manual”;Lewin,“Genes VIII”;及Roitt et a1.,“Immunology”(第8版),以及本文中引用的一般现有技术;此外,除非另有说明,否则未具体详述的所有方法、步骤、技术及操作均可以且已经以本身已知的方式进行,该方式将为本领域技术人员所了解。亦参考例如标准手册、上述一般现有技术及其中引用的其他参考文献。
除非另有说明,否则可互换使用的术语“抗体”或“免疫球蛋白”在本文中无论是指重链抗体还是指常规4链抗体,均用作一般术语以包括全长抗体、其单个的链以及其所有部分、结构域或片段(包括但不限于抗原结合结构域或片段,分别例如VHH结构域或VH/VL结构域)。此外,本文所用的术语“序列”(例如在“免疫球蛋白序列”、“抗体序列”、“单一可变结构域序列”、“VHH序列”或“蛋白序列”等的术语中)一般应理解为既包括相关氨基酸序列,又包括编码所述序列的核酸序列或核苷酸序列,除非本文需要更限定的解释。
如本文所用,术语(多肽或蛋白的)“结构域”是指折叠蛋白结构,其能够独立于蛋白的其余部分维持其三级结构。一般而言,结构域负责蛋白的单个的功能性质,且在许多情况下可添加、移除或转移至其他蛋白而不损失蛋白的其余部分和/或结构域的功能。
如本文所用的术语“免疫球蛋白结构域”是指抗体链(例如常规4链抗体的链或重链抗体的链)的球形区域,或是指基本上由这类球形区域组成的多肽。免疫球蛋白结构域的特征在于其维持抗体分子的免疫球蛋白折叠特征,其由排列在两个β折叠中任选由保守二硫键稳定的约7个反平行β折叠股的2层夹层组成。
如本文所用的术语“免疫球蛋白可变结构域”是指基本上由本领域及下文中分别称为“框架区1”或“FR1”、“框架区2”或“FR2”、“框架区3”或“FR3”、及“框架区4”或“FR4”的四个“框架区”组成的免疫球蛋白结构域,其中所述框架区由本领域及下文中分别称为“互补决定区1”或“CDR1”、“互补决定区2”或“CDR2”、及“互补决定区3”或“CDR3”的三个“互补决定区”或“CDR”间隔开。因此,免疫球蛋白可变结构域的一般结构或序列可如下表示为:FR1-CDR1-FR2-CDR2-FR3-CDR3-FR4。免疫球蛋白可变结构域因具有抗原结合位点而赋予抗体对抗原的特异性。
如本文所用的术语“免疫球蛋白单一可变结构域”是指能够在不与其他免疫球蛋白可变结构域配对的情况下特异性结合抗原表位的免疫球蛋白可变结构域。本发明含义中的免疫球蛋白单一可变结构域的一个实例为“结构域抗体”,例如免疫球蛋白单一可变结构域VH及VL(VH结构域及VL结构域)。免疫球蛋白单一可变结构域的另一实例为如下文定义的骆驼科的“VHH结构域”(或简称为“VHH”)。
“VHH结构域”,亦称为重链单域抗体、VHH、VHH结构域、VHH抗体片段和VHH抗体,是称为“重链抗体”(即“缺乏轻链的抗体”)的抗原结合免疫球蛋白的可变结构域(Hamers-Casterman C,Atarhouch T,Muyldermans S,Robinson G,Hamers C,Songa EB,BendahmanN,Hamers R.:“Naturally occurring antibodies devoid of light chains”;Nature363,446-448(1993))。使用术语“VHH结构域”以将所述可变结构域与存在于常规4链抗体中的重链可变结构域(其在本文中称为“VH结构域”)以及存在于常规4链抗体中的轻链可变结构域(其在本文中称为“VL结构域”)进行区分。VHH结构域特异性结合表位而无需其他抗原结合结构域(此与常规4链抗体中的VH或VL结构域相反,在该情况下表位由VL结构域与VH结构域一起识别)。VHH结构域为由单一免疫球蛋白结构域形成的小型稳定及高效的抗原识别单元。
在本发明的上下文中,术语“重链单域抗体”、“VHH结构域”、“VHH”、“VHH结构域”、“VHH抗体片段”、“VHH抗体”以及

及“
Figure BDA0002041250900000052
结构域”(“Nanobody”为Ablynx N.V.公司,Ghent,Belgium的商标)可互换使用。
例如Riechmann及Muyldermans,J.Immunol.Methods 231,25-38(1999)的图2中所示,对于骆驼科的VHH结构域所应用的氨基酸残基,根据Kabat等人给出的VH结构域的一般编号法来编号(“Sequence of proteins of immunological interest”,US PublicHealth Services,NIH Bethesda,MD,公开案第91号)。根据该编号法,
-FR1包含在位置1-30处的氨基酸残基,
-CDR1包含在位置31-35处的氨基酸残基,
-FR2包含在位置36-49处的氨基酸,
-CDR2包含在位置50-65处的氨基酸残基,
-FR3包含在位置66-94处的氨基酸残基,
-CDR3包含在位置95-102处的氨基酸残基,且
-FR4包含在位置103-113处的氨基酸残基。
然而应注意,如本领域中对于VH结构域及VHH结构域所公知的,各CDR中的氨基酸残基的总数可能不同,且可能不对应于由Kabat编号指示的氨基酸残基的总数(即根据Kabat编号的一个或多个位置可能在实际序列中未被占据,或实际序列可能含有多于Kabat编号所允许数目的氨基酸残基)。这意味着一般而言,根据Kabat的编号可能对应或可能不对应于实际序列中氨基酸残基的实际编号。
本领域中已知还有对VH结构域的氨基酸残基进行编号的其他系统,如Chothia编号系统。Chothia的氨基酸编号与Kabat相同,但其将对CDR区划分是基于抗体可变区结构中的环(loop)区来进行的,因此在CDR区所包含的氨基酸区域上会与Kabat的有所不同。此外还有AbM编码系统等。所述其他编码系统也可以类似地应用于VHH结构域。然而,除非另有说明,否则在本说明书、权利要求书及附图中,将遵循如上所述的根据Kabat且适于VHH结构域的编号,或者综合Kabat与Chothia的编号。
VHH结构域中的氨基酸残基的总数将通常在110至120范围内,常常介于112与115之间。然而应注意较小及较长序列也可适于本文所述的目的。
VHH结构域及含有其的多肽的其他结构特性及功能性质可总结如下:
VHH结构域(其已经天然“设计”以在不存在轻链可变结构域且不与轻链可变结构域相互作用的情况下与抗原功能性结合)可用作单一且相对较小的功能性抗原结合结构单元、结构域或多肽。此区分VHH结构域与常规4链抗体的VH及VL结构域,这些VH及VL结构域自身通常不适于作为单一抗原结合蛋白或免疫球蛋白单一可变结构域进行实际应用,但需要以某种形式或另一形式组合以提供功能性抗原结合单元(如以诸如Fab片段等常规抗体片段的形式;或以由与VL结构域共价连接的VH结构域组成的scFv的形式)。
由于这些独特性质,使用VHH结构域一单独或作为较大多肽的一部分一提供许多优于使用常规VH及VL结构域、scFv或常规抗体片段(例如Fab-或F(ab’)2-片段)的显著优势:仅需要单一结构域以高亲和力及高选择性结合抗原,从而使得既不需要存在两个单独结构域,也不需要确保该两个结构域以适当空间构象及构型存在(例如scFv一般需要使用经特别设计的接头);VHH结构域可自单一基因表达且不需要翻译后折叠或修饰;VHH结构域可容易地改造成多价及多特异性格式(格式化);VHH结构域高度可溶且无聚集趋势;VHH结构域对热、pH、蛋白酶及其他变性剂或条件高度稳定,且因此可在制备、储存或运输中不使用冷冻设备,从而达成节约成本、时间及环境;VHH结构域易于制备且相对廉价,甚至在生产所需的规模上亦如此;VHH结构域与常规4链抗体及其抗原结合片段相比相对较小(大约15kDa或大小为常规IgG的1/10),因此相比于常规4链抗体及其抗原结合片段,显示较高的组织渗透性且可以较高剂量给药;VHH结构域可显示所谓腔结合性质(尤其由于与常规VH结构域相比其延长的CDR3环),从而可到达常规4链抗体及其抗原结合片段不可到达的靶及表位。
获得结合特定抗原或表位的VHH的方法,先前已公开于以下文献中:R.van derLinden et a1.,Journal of Immunological Methods,240(2000)185-195;Li et al.,JBiol Chem.,287(2012)13713-13721;Deffar et a1.,African Journal ofBiotechnologyVol.8(12),pp.2645-2652,17June,2009;WO94/04678;US7790367,2006-09-14,METHOD FORSCREENING A LIBRARY OF VHH POLYPEPTIDES,Casterman,Cecile,Hamers,Raymond;和US7786047,2006-02-10,IMMUNOGLOBULINS DEVOID OF LIGHTCHAINS,Casterman,Cecile,Hamers,Raymond。
此外,本领域技术人员还将了解,有可能将一个或多个上述CDR“移植”于其他“支架”(包括但不限于人支架或非免疫球蛋白支架)上。适于所述CDR移植的支架及技术在本领域中是已知的。
如本文所用,术语“表位”或可互换使用的术语“抗原决定簇”指抗体的互补位所结合的抗原上的任何抗原决定簇。抗原决定簇通常包含分子的化学活性表面基团,例如氨基酸或糖侧链,并且通常具有特定的三维结构特征以及特定的电荷特征。例如,表位通常以独特的空间构象包括至少3、4、5、6、7、8、9、10、11、12、13、14或15个连续或非连续的氨基酸,其可以是“线性”表位或“构象”表位。参见,例如,Epitope Mapping Protocols in Methodsin Molecular Biology,第66卷,G.E.Morris,Ed.(1996)。在线性表位中,蛋白质与相互作用分子(例如抗体)之间的所有相互作用的点沿着蛋白质的一级氨基酸序列线性存在。在构象表位中,相互作用的点跨越彼此分开的蛋白质氨基酸残基而存在。
可使用本领域中熟知的许多表位定位技术鉴别给定抗原的表位。参见例如Epitope Mapping Protocols in Methods in Molecular Biology,第66卷,G.E.Morris,Ed.(1996)。举例而言,线性表位可通过例如以下方法来确定:在固体支持物上同时合成大量肽,其中这些肽对应于蛋白质分子的各部分,且使这些肽在仍然与支持物连接的情况下与抗体反应。这些技术在本领域中为已知的且描述于例如美国专利第4,708,871号;Geysen等人(1984)Proc.Natl.Acad.Sci.USA 81:3998-4002;Geysen等人(1986)Molec.Immunol.23:709-715中。类似地,构象表位可通过诸如通过例如x射线结晶学及2维核磁共振确定氨基酸的空间构形加以鉴别。参见例如Epitope Mapping Protocols(同上)。
可使用本领域技术人员已知的常规技术,就与相同表位的结合竞争性筛选抗体。例如,可进行竞争和交叉竞争研究,以获得彼此竞争或交叉竞争与抗原结合的抗体。基于它们的交叉竞争来获得结合相同表位的抗体的高通量方法描述于国际专利申请WO03/48731中。因此,可使用本领域技术人员已知的常规技术,获得与本发明的抗体分子竞争结合KN044上的相同表位的抗体及其抗原结合片段。
一般而言,术语“特异性”是指特定抗原结合分子或抗原结合蛋白(例如本发明的免疫球蛋白单一可变结构域)分子可结合的不同类型抗原或表位的数目。可基于抗原结合分子的亲和力和/或亲合力确定其特异性。由抗原与抗原结合蛋白的解离平衡常数(KD)所表示的亲和力,是表位与抗原结合蛋白上抗原结合位点之间结合强度的量度:KD值越小,表位与抗原结合分子之间的结合强度越强(或者,亲和力也可表示为缔合常数(KA),其为1/KD)。如本领域技术人员将了解,取决于具体感兴趣的抗原,可以以已知方式测定亲和力。亲合力为抗原结合分子(例如免疫球蛋白、抗体、免疫球蛋白单一可变结构域或含有其的多肽)与相关抗原之间结合强度的量度。亲合力与以下两者有关:与其抗原结合分子上的抗原结合位点之间的亲和力,以及存在于抗原结合分子上的相关结合位点的数目。
如本文所用,术语“针对KN044的结合分子”意指任何能够以高亲和力结合KN044的分子。针对KN044的结合分子可以包括针对KN044的如本文定义的抗体或其缀合物。针对KN044的结合分子还涵盖免疫球蛋白超家族抗体(IgSF)或CDR移植分子。

相比于其天然生物来源和/或获得该多肽或核酸分子的反应介质或培养基,当其已与至少一种在该来源或介质(培养基)中通常与之相关的其他组分(例如另一蛋白/多肽、另一核酸、另一生物组分或大分子或至少一种污染物、杂质或微量组分)分离时,多肽或核酸分子视为“基本上分离的”。特别地,多肽或核酸分子在其已纯化至少2倍、特别是至少10倍、更特别是至少100倍且多达1000倍或1000倍以上时被视为“基本上分离的”。经适合的技术(例如适合色谱技术,如聚丙烯酰胺凝胶电泳)确定,“基本上分离的”多肽或核酸分子优选基本上为均质的。
“亲和力成熟”的针对KN044的抗体,特别是VHH或结构域抗体,在一个或多个CDR中具有一个或多个变化,所述变化导致对KN044的亲和力相比于其各自的亲本针对KN044的抗体有所增加。亲和力成熟的针对KN044的抗体可通过例如由以下所述的本领域中已知的方法来制备:Marks等人,1992,Biotechnology 10:779-783或Barbas等人,1994,Proc.Nat.Acad.Sci,USA 91:3809-3813.;Shier等人,1995,Gene 169:147-155;Yelton等人,1995,Immunol.155:1994-2004;Jackson等人,1995,J.Immunol.154(7):3310-9;及Hawkins等人,1992,J.MoI.Biol.226(3):889896;KS Johnson及RE Hawkins,“Affinitymaturation of antibodies using phage display”,Oxford University Press 1996。

将2.1构建获得载体转染至HEK293细胞进行抗体的瞬时表达。将重组表达质粒用Freestyle293培养基稀释并加入转化所需聚乙烯亚胺(PEI)溶液,将每组质粒/PEI混合物分别加入HEK293细胞悬液中,放置在37℃,5%CO2,130rpm培养。四小时后补加EX-CELL293培养基,130rpm悬浮培养。24小时后加3.8mM VPA,72小时后加入4g/L葡萄糖。培养5~6天后,收集瞬时表达培养上清液,通过Protein A亲和层析法,纯化目标针对KN044的单域抗体-Fc融合蛋白和/或针对KN044的单域抗体-muFc融合蛋白。通过SDS-PAGE以及SEC-HPLC检测所获得的蛋白质的纯度。各蛋白质表达情况和纯度分析见下表2:
表2:所获得的针对KN044的单域抗体-FC融合蛋白瞬转后一步纯化结果
抗体 表达量(mg/L) SDS-PAGE纯度% 单体比例%
nKN044-19-3-Fc 358.5 >95% 98.97
nKN044-19-3-muFc 384 >95% 96.47
nKN044-97-Fc 93.6 >95% 95.69
可见,针对KN044的单域抗体-Fc融合蛋白nKN044-19-3-Fc和nKN044-19-3-muFc表达量均在300mg/L以上,且经过Protein A亲和层析柱一步纯化后,获得了具有稳定浓度以及高纯度的目的蛋白质;nKN044-97-Fc表达量相对低一些,但纯度很高,满足实验需求。
实施例3:鉴定针对KN044的单域抗体-Fc融合蛋白的功能
3.1针对KN044的单域抗体-Fc融合蛋白与抗原KN044的结合曲线
以0.5μg/孔的量用实施例2所得的针对KN044的单域抗体-Fc融合蛋白包被平板,同时设置阳性对照,4℃过夜。加入KN044-Biotin的梯度稀释系列,室温下反应2小时。洗涤之后加入辣根过氧化物酶标记链霉亲和素(streptavidin-HRP,SIGMA),室温反应1.5小时。洗涤之后加入显色液,读取450nm和650nm波长的吸光度值,450nm波长的吸光度值减去650nm波长的吸光度值为最终的吸光度值。应用软件SotfMax Pro v5.4进行数据处理和作图分析,通过四参数拟合,得到针对KN044的单域抗体-Fc融合蛋白与KN044的结合曲线及EC50值,以反映抗体对KN044的亲和能力。
结果见图3,其中纵坐标为OD值,横坐标为KN044-Biotin蛋白的浓度(单位ng/mL);圆形、方形、正三角、倒三角分别代表针对KN044的单域抗体-Fc融合蛋白:nKN044-19-3-Fc、nKN044-19-3-muFc、nKN044-97-Fc、阳性对照。抗体nKN044-19-3-Fc和nKN044-19-3-muFc对KN044均有很高的亲和力,且与阳性对照相差不大;抗体nKN044-97-Fc对KN044没有结合。
3.2竞争ELISA考察针对KN044的单域抗体-Fc融合蛋白对CTLA4和KN044相互作用的阻断效果
以0.5μg/孔的量用CTLA4-muFc融合蛋白包被平板,同时设置阴性对照,4℃过夜。加入实施例2所得的融合蛋白nKN044-19-3-muFc的梯度稀释系列(对照组只是缓冲液)以及20ng/孔KN044(空白组不加入任何抗体或蛋白,只加入等体积缓冲液),室温下反应2小时。之后加入山羊抗人IgG(Fc特异性)-HRP(购自Sigma公司),室温反应2小时。洗涤之后加入显色液,读取450nm和650nm波长吸光度值,450nm波长的吸光度值减去650nm波长的吸光度值为最终的吸光度值。当样品OD值比对照OD值<0.8时,则认为抗体有阻断效果。结果显示,抗体nKN044-19-3-muFc对CTLA4和KN044相互作用无阻断效应。
3.3 Bridging ELISA验证针对KN044的单域抗体-Fc融合蛋白作为KN044抗药抗体(ADA)检测中的阳性抗体
用KN044包被平板,4℃过夜。加入实施例2所得的融合蛋白nKN044-19-3-muFc的梯度稀释系列,稀释液分别为1%BSA-0.05%PBST、1X人空白血浆、1X食蟹猴空白血浆,同时设空白对照组,室温下反应2小时。之后加入KN044-Biotin,室温反应2小时。洗涤之后加入辣根过氧化物酶标记链霉亲和素(streptavidin-HRP,SIGMA),室温反应1.5小时。洗涤之后加入显色液,读取450nm和650nm波长吸光度值,450nm波长的吸光度值减去650nm波长的吸光度值为最终的吸光度值。应用软件SotfMax Pro v5.4进行数据处理和作图分析,通过四参数拟合,得到不同稀释液稀释后的抗体与KN044的结合曲线及EC50值,以反映不同稀释液中成分对抗体的中和作用。
结果见表3。由结果可知,nKN044-19-3-Fc能够通过ADA bridging ELISA的方法检出,且保持较好的灵敏度。而其在未稀释的人空白血浆和食蟹猴空白血浆中仍然能被检出,且其灵敏度与在PBST稀释液中时基本一致。因此,抗体nKN044-19-3-Fc可以作为KN044抗药抗体(ADA)检测中的阳性抗体。
