Description

识别NY-ESO-1抗原的高亲和力T细胞受体
技术领域
本发明涉及生物技术领域;更具体地,涉及能够识别衍生自NY-ESO-1蛋白多肽的T细胞受体(T cell receptor,TCR)。本发明还涉及所述受体的制备和用途。
背景技术
仅仅有两种类型的分子能够以特异性的方式识别抗原。其中一种是免疫球蛋白或抗体;另一种是T细胞受体(TCR),它是由α链/β链或者γ链/δ链以异二聚体形式存在的细胞膜表面的糖蛋白。免疫系统的TCR总谱的组成是在胸腺中通过V(D)J重组,然后进行阳性和阴性选择而产生的。在外周环境中,TCR介导了T细胞对主组织相容性复合体-肽复合物(pMHC)的特异性识别,因此其对免疫系统的细胞免疫功能是至关重要的。
TCR是呈递在主组织相容性复合体(MHC)上的特异性抗原肽的唯一受体,这种外源肽或内源肽可能会是细胞出现异常的唯一迹象。在免疫系统中,通过抗原特异性的TCR与pMHC复合物的结合引发T细胞与抗原呈递细胞(APC)直接的物理接触,然后T细胞及APC两者的其他细胞膜表面分子就发生相互作用,这就引起了一系列后续的细胞信号传递和其他生理反应,从而使得不同抗原特异性的T细胞对其靶细胞发挥免疫效应。
与TCR相对应的MHC I类和II类分子配体也是免疫球蛋白超家族的蛋白质但对于抗原的呈递具有特异性,不同的个体有不同的MHC,从而能呈递一种蛋白抗原中不同的短肽到各自的APC细胞表面。人类的MHC通常称为HLA基因或HLA复合体。
短肽SLLMWITQC源自于被多种肿瘤细胞表达的NY-ESO-1蛋白(Chen et al.,(1997)PNAS USA 94 1914-1918)。肿瘤细胞的Ⅰ型HLA分子呈递包括SLLMWITQC在内的源自于NY-ESO-1的短肽。因此,SLLMWITQC-HLA A0201复合物提供了一种TCR可靶向肿瘤细胞的标记。能够结合SLLMWITQC-HLA A0201复合物的TCR对肿瘤的治疗具有很高的应用价值。例如,能够靶向该肿瘤细胞标记的TCR可用于将细胞毒性剂或免疫刺激剂递送到靶细胞,或被转化入T细胞,使表达该TCR的T细胞能够破坏肿瘤细胞,以便在被称为过继免疫治疗的治疗过程中给予患者。对于前一目的,理想的TCR是具有较高的亲和力的,从而使该TCR能够长期驻留在所靶向的细胞上面。对于后一目的,则优选使用中等亲和力的TCR。因此,本领域技术人员致力于开发可用于满足不同目的的靶向肿瘤细胞标记的TCR。

虽然在本发明的实施或测试中可以使用与本发明中所述相似或等价的任何方法和材料,本文在此处例举优选的方法和材料。
术语
T细胞受体(T cell receptor,TCR)
可以采用国际免疫遗传学信息系统(IMGT)来描述TCR。天然αβ异源二聚TCR具有α链和β链。广义上讲,各链包含可变区、连接区和恒定区,β链通常还在可变区和连接区之间含有短的多变区,但该多变区常视作连接区的一部分。通过独特的IMGT的TRAJ和TRBJ确定TCR的连接区,通过IMGT的TRAC和TRBC确定TCR的恒定区。
各可变区包含嵌合在框架序列中的3个CDR(互补决定区),CDR1、CDR2和CDR3。在IMGT命名法中,TRAV和TRBV的不同编号分别指代不同Vα类型和Vβ的类型。在IMGT系统中,α链恒定结构域具有以下的符号:TRAC*01,其中“TR”表示T细胞受体基因;“A”表示α链基因;C表示恒定区;“*01”表示等位基因1。β链恒定结构域具有以下的符号:TRBC1*01或TRBC2*01,其中“TR”表示T细胞受体基因;“B”表示β链基因;C表示恒定区;“*01”表示等位基因1。α链的恒定区是唯一确定的,在β链的形式中,存在两个可能的恒定区基因“C1”和“C2”。本领域技术人员通过公开的IMGT数据库可以获得TCRα与β链的恒定区基因序列。
TCR的α和β链一般看作各有两个“结构域”即可变域和恒定结构域。可变域由连接的可变区和连接区构成。因此,在本申请的说明书和权利要求书中,“TCRα链可变域”指连接的TRAV和TRAJ区,同样地,“TCRβ链可变域”指连接的TRBV和TRBD/TRBJ区。TCRα链可变域的3个CDR分别为CDR1α、CDR2α和CDR3α;TCRβ链可变域的3个CDR分别为CDR1β、CDR2β和CDR3β。本发明TCR可变域的框架序列可以为鼠源的或人源的,优选为人源的。TCR的恒定结构域包含胞内部分、跨膜区和胞外部分。为获得可溶性TCR,以便测定TCR与SLLMWITQC-HLA A0201复合物之间的亲和力,本发明TCR优选地不包含跨膜区。更优选地,本发明TCR的氨基酸序列是指TCR的胞外氨基酸序列。
本发明中所用的TCR序列为人源的。本发明中所述“野生型TCR”的α链氨基酸序列及β链胞外氨基酸序列分别为SEQ ID NO:123和SEQ ID NO:124,如图11a和11b所示。本发明中所述“参比TCR”的α链氨基酸序列及β链氨基酸序列分别为SEQ ID NO:54和SEQ ID NO:55,如图8a和8b所示。本发明中所述“野生型TCR”的α链氨基酸序列及β链氨基酸序列分别为SEQ ID NO:125和SEQ ID NO:126,如图19a和19b所示。本发明中,能够结合SLLMWITQC-HLAA0201复合物的野生型TCR的α与β链可变域氨基酸序列分别为SEQ ID NO:1和SEQ ID NO:2,如图1a和1b所示。在本发明中,术语“本发明多肽”、“本发明的TCR”、“本发明的T细胞受体”可互换使用。
天然链间二硫键与人工链间二硫键
在天然TCR的近膜区Cα与Cβ链间存在一组二硫键,本发明中称为“天然链间二硫键”。在本发明中,将人工引入的,位置与天然链间二硫键的位置不同的链间共价二硫键称为“人工链间二硫键”。
为方便描述,本发明中TRAC*01与TRBC1*01或TRBC2*01氨基酸序列的位置编号按从N端到C端依次的顺序进行位置编号,如TRBC1*01或TRBC2*01中,按从N端到C端依次的顺序第60个氨基酸为P(脯氨酸),则本发明中可将其描述为TRBC1*01或TRBC2*01外显子1的Pro60,也可将其表述为TRBC1*01或TRBC2*01外显子1的第60位氨基酸,又如TRBC1*01或TRBC2*01中,按从N端到C端依次的顺序第61个氨基酸为Q(谷氨酰胺),则本发明中可将其描述为TRBC1*01或TRBC2*01外显子1的Gln61,也可将其表述为TRBC1*01或TRBC2*01外显子1的第61位氨基酸,其他以此类推。本发明中,可变区TRAV与TRBV的氨基酸序列的位置编号,按照IMGT中列出的位置编号。如TRAV中的某个氨基酸,IMGT中列出的位置编号为46,则本发明中将其描述为TRAV第46位氨基酸,其他以此类推。本发明中,其他氨基酸的序列位置编号有特殊说明的,则按特殊说明。
肿瘤
术语“肿瘤”指包括所有类型的癌细胞生长或致癌过程,转移性组织或恶性转化细胞、组织或器官,不管病理类型或侵染的阶段。肿瘤的实施例非限制性地包括:实体瘤,软组织瘤,和转移性病灶。实体瘤的实施例包括:不同器官系统的恶性肿瘤,例如肉瘤,肺鳞癌和癌症。例如:感染的前列腺,肺,乳房,淋巴,肠胃(例如:结肠),和生殖泌尿道(例如:肾脏,上皮细胞),咽头。肺鳞癌包括恶性肿瘤,例如,多数的结肠癌,直肠癌,肾细胞癌,肝癌,肺部的非小细胞癌,小肠癌和食道癌。上述癌症的转移性病变可同样用本发明的方法和组合物来治疗和预防。
发明详述
众所周知,TCR的α链可变域与β链可变域各含有3个CDR,类似于抗体的互补决定区。CDR3与抗原短肽相互作用,CDR1和CDR2与HLA相互作用。因此,TCR分子的CDR决定了其与抗原短肽-HLA复合物的相互作用。能够结合抗原短肽SLLMWITQC与HLA A0201复合物(即,SLLMWITQC-HLA A0201复合物)的野生型TCR的α链可变域氨基酸序列与β链可变域氨基酸序列分别为SEQ ID NO:1和SEQ ID NO:2。其具有下列CDR区:
α链可变域,包括CDR1α:TSINNCDR;2α:IRSNERECDR;3α:ATDANGKII和β链可变域CDR,包括CDR1β:SGHDY;CDR2β:FNNNVP;CDR3β:ASSLGSNEQY。
本发明通过对上述CDR区进行突变筛选,获得了与SLLMWITQC-HLA A0201复合物的亲和力是野生型TCR与SLLMWITQC-HLA A0201复合物亲和力至少2倍的高亲和力TCR。
本发明提供了一种T细胞受体(TCR),其具有结合SLLMWITQC-HLA A0201复合物的活性。
本发明中野生型TCRα链可变域SEQ ID NO:1的3个CDR即CDR1、CDR2和CDR3分别位于SEQ ID NO:1的第27-31位、第49-55位和第90-98位。据此,氨基酸残基编号采用SEQ IDNO:1所示的编号,27T即为CDR1α的第1位T,28S即为CDR1α的第2位S,29I即为CDR1α的第3位I,30N即为CDR1α的第4位N,51S即为CDR2α的第3位S,52N即为CDR2α的第4位N,53E即为CDR2α的第5位E,54R即为CDR2α的第6位R,90A即为CDR3α的第1位A,91T即为CDR3α的第2位T,93A即为CDR3α的第4位A,94N即为CDR3α的第5位N,95G即为CDR3α的第6位G,96K即为CDR3α的第7位K,97I即为CDR3α的第8位I,98I即为CDR3α的第9位I。

本发明提供具有结合SLLMWITQC-HLA A0201复合物的特性的TCR,并包含α链可变域和β链可变域,其特征在于,所述TCR在SEQ ID NO:1所示的α链可变域中发生突变,所述突变的氨基酸残基位点包括27T、28S、29I、30N、51S、52N、53E、54R、90A、91T、93A、94N、95G、96K、97I和98I中的一个或多个,其中,氨基酸残基编号采用SEQ ID NO:1所示的编号;和/或所述TCR在SEQ ID NO:2所示的β链可变域中发生突变,所述突变的氨基酸残基位点包括51N、52N、53V、54P、93A、95S、96L、97G、98S、99N、100E、101Q和102Y中的一个或多个,其中,氨基酸残基编号采用SEQ ID NO:2所示的编号;
优选地,突变后的所述TCRα链可变域包括选自下组的一个或多个氨基酸残基:27G或27Q或27V、28W或28T或28N、29A或29P、30Q、51T、52G、53Q、54A、90G或90L或90M、91F或91W或91Y、93E或93H或93M或93Q或93R或93S、94A或94D或94F或94H或94S或94W、95A、96R或96Q或96S或96L或96T或96W、97W或97V或97M或97P和98F或98E或98D或98H或98L或98Q或98R或98T或98Y,其中,氨基酸残基编号采用SEQ ID NO:1所示的编号;和/或突变后的所述TCRβ链可变域包括选自下组的一个或多个氨基酸残基:51H、52G、53A、54L、93S、95Q、96R或96K或96H或96Q、97A、98A或98G或98P、99G、100P、101W和102I,氨基酸残基编号采用SEQ ID NO:2所示的编号。
更具体地,α链可变域中所述突变的具体形式包括T27G/Q/V、S28W/T/N、I29A/P、N30Q、S51T、N52G、E53Q、R54A、A90G/L/M、T91F/W/Y、A93E/H/M/Q/R/S、N94A/D/F/H/S/W、G95A、K96R/Q/S/L/T/W、I97W/V/M/P和I98F/E/D/H/L/Q/R/T/Y中的一组或几组;β链可变域中所述突变的具体形式包括N51H、N52G、V53A、P54L、A93S、S95Q、L96R/K/H/Q、G97A、S98A/G/P、N99G、E100P、Q101W、Y102I中的一组或几组。
进一步,本发明所述TCR是αβ异质二聚TCR,所述TCR的α链可变域包含与SEQ IDNO:1所示的氨基酸序列有至少85%,优选地,至少90%;更优选地,至少92%;最优选地,至少94%(如,可以是至少88%、89%、90%、91%、92%、93%、94%、95%、96%、97%、98%、99%的序列同源性)的序列同源性的氨基酸序列;和/或所述TCR的β链可变域包含与SEQ IDNO:2所示的氨基酸序列有至少90%,优选地,至少92%;更优选地,至少94%;最优选地,至少97%;(如,可以是至少91%、92%、93%、94%、95%、96%、97%、98%、99%的序列同源性)的序列同源性的氨基酸序列。
进一步,本发明所述TCR是单链TCR,所述TCR的α链可变域包含与SEQ ID NO:3所示的氨基酸序列有至少85%,优选地,至少90%;更优选地,至少92%;最优选地,至少94%(如,可以是至少88%、89%、90%、91%、92%、93%、94%、95%、96%、97%、98%、99%的序列同源性)的序列同源性的氨基酸序列;和/或所述TCR的β链可变域包含与SEQ ID NO:4所示的氨基酸序列有至少90%,优选地,至少92%;更优选地,至少94%;最优选地,至少97%;(如,可以是至少91%、92%、93%、94%、95%、96%、97%、98%、99%的序列同源性)的序列同源性的氨基酸序列。
优选地,所述TCR包含(i)除其跨膜结构域以外的全部或部分TCRα链,和(ii)除其跨膜结构域以外的全部或部分TCRβ链,其中(i)和(ii)均包含TCR链的可变域和至少一部分恒定域。
根据本领域技术人员熟知的定点突变的方法,将野生型TCRα链恒定区TRAC*01外显子1的Thr48突变为半胱氨酸,β链恒定区TRBC1*01或TRBC2*01外显子1的Ser57突变为半胱氨酸,即得到参比TCR,其氨基酸序列分别如图8a和8b所示,突变后的半胱氨酸残基以加粗字母表示。上述半胱氨酸取代能使参比TCR的α与β链的恒定区之间形成人工链间二硫键,以形成更加稳定的可溶性TCR,从而能够更加方便地评估TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力和/或结合半衰期。应理解,TCR可变区的CDR区决定了其与pMHC复合物之间的亲和力,因此,上述TCR恒定区的半胱氨酸取代并不会对TCR的结合亲和力和/或结合半衰期产生影响。所以,在本发明中,测得的参比TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力即认为是野生型TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力。同样地,如果测得本发明TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力是参比TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力的至少10倍,即等同于本发明TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力是野生型TCR与SLLMWITQC-HLA A0201复合物之间的结合亲和力的至少10倍。
可通过任何合适的方法测定结合亲和力(与解离平衡常数KD成反比)和结合半衰期(表示为T1/2)。如采用表面等离子共振技术进行检测。应了解,TCR的亲和力翻倍将导致KD减半。T1/2计算为In2除以解离速率(Koff)。因此,T1/2翻倍会导致Koff减半。优选采用相同的试验方案检测给定TCR的结合亲和力或结合半衰期数次,例如3次或更多,取结果的平均值。在优选的实施方式中,采用本发明实施例中的表面等离振子共振方法检测可溶性TCR的亲和力,条件为:温度25℃,PH值为7.1-7.5。该方法检测到参比TCR对SLLMWITQC-HLA A0201复合物的解离平衡常数KD为4.3E-05M,即43μM,本发明中即认为野生型TCR对SLLMWITQC-HLAA0201复合物的解离平衡常数KD也为43μM。由于TCR的亲和力翻倍将导致KD减半,所以若检测到高亲和力TCR对SLLMWITQC-HLA A0201复合物的解离平衡常数KD为4.3E-06M,即4.3μM,则说明该高亲和力TCR对SLLMWITQC-HLA A0201复合物的亲和力是野生型TCR对SLLMWITQC-HLA A0201复合物的亲和力的10倍。本领域技术人员熟知KD值单位间的换算关系,即1M=1000μM,1μM=1000nM,1nM=1000pM。
在本发明的一个优选例中,所述TCR与SLLMWITQC-HLA A0201复合物的亲和力是野生型TCR的至少2倍;优选地,至少5倍;更优选地,至少10倍。
在另一优选例中,所述TCR与SLLMWITQC-HLA A0201复合物的亲和力是野生型TCR的至少50倍;优选地,至少100倍;更优选地,至少500倍;最优选地,至少1000倍。
在另一优选例中,所述TCR与SLLMWITQC-HLA A0201复合物的亲和力是野生型TCR的至少104倍;优选地,至少105倍;更优选地,至少106倍。
具体地,所述TCR对SLLMWITQC-HLA A0201复合物的解离平衡常数KD≤20μM;
在另一优选例中,所述TCR对SLLMWITQC-HLA A0201复合物的解离平衡常数5μM≤KD≤10μM;优选地,0.1μM≤KD≤1μM;更优选地,1nM≤KD≤100nM;
在另一优选例中,所述TCR对SLLMWITQC-HLA A0201复合物的解离平衡常数100pM≤KD≤1000pM;优选地,10pM≤KD≤100pM。
可采用任何合适的方法进行突变,包括但不限于依据聚合酶链式反应(PCR)的那些、依据限制性酶的克隆或不依赖连接的克隆(LIC)方法。许多标准分子生物学教材详述了这些方法。聚合酶链式反应(PCR)诱变和依据限制性酶的克隆的更多细节可参见Sambrook和Russell,(2001)分子克隆-实验室手册(Molecular Cloning-A Laboratory Manual)(第三版)CSHL出版社。LIC方法的更多信息可见(Rashtchian,(1995)Curr Opin Biotechnol 6(1):30-6)。
产生本发明的TCR的方法可以是但不限于从展示此类TCR的噬菌体颗粒的多样性文库中筛选出对SLLMWITQC-HLA-A0201复合物具有高亲和性的TCR,如文献(Li,et al(2005)Nature Biotech 23(3):349-354)中所述。
应理解,表达野生型TCRα和β链可变域氨基酸的基因或者表达略作修饰的野生型TCR的α和β链可变域氨基酸的基因都可用来制备模板TCR。然后在编码该模板TCR的可变域的DNA中引入产生本发明的高亲和力TCR所需的改变。
本发明的高亲和性TCR包含α链可变域氨基酸序列SEQ ID NO:56-107之一和/或β链可变域氨基酸序列SEQ ID NO:108-122之一。因此,含有野生型TCR的α链可变域氨基酸序列(SEQ ID NO:1)的TCRα链可与包含SEQ ID NO:108-122之一的TCRβ链组合形成异质二聚TCR或单链TCR分子。或者,含有野生型TCR的β可变域氨基酸序列(SEQ ID NO:2)的TCRβ链可与包含SEQ ID NO:56-107之一的TCRα链组合形成异质二聚TCR或单链TCR分子。又或者,包含TCRα链可变域氨基酸序列SEQ ID NO:56-107之一的TCRα链可与包含TCRβ链可变域氨基酸序列SEQ ID NO:108-122之一的TCRβ链组合形成异质二聚TCR或单链TCR分子。本发明中,形成异质二聚TCR分子的α链可变域与β链可变域的氨基酸序列优选自下表1:

基于本发明的目的,本发明TCR是具有至少一个TCRα和/或TCRβ链可变域的部分。它们通常同时包含TCRα链可变域和TCRβ链可变域。它们可以是αβ异源二聚体或是单链形式或是其他任何能够稳定存在的形式。在过继性免疫治疗中,可将αβ异源二聚TCR的全长链(包含胞质和跨膜结构域)进行转染。本发明TCR可用作将治疗剂递送至抗原呈递细胞的靶向剂或与其他分子结合制备双功能多肽来定向效应细胞,此时TCR优选为可溶形式。
对于稳定性而言,现有技术中公开了在TCR的α与β链恒定域之间引入人工链间二硫键能够获得可溶且稳定的TCR分子,如专利文献PCT/CN2015/093806中所述。因此,本发明TCR可以是在其α和β链恒定域的残基之间引入人工链间二硫键的TCR。半胱氨酸残基在所述TCR的α和β链恒定域间形成人工链间二硫键。半胱氨酸残基可以取代在天然TCR中合适位点的其他氨基酸残基以形成人工链间二硫键。例如,取代TRAC*01外显子1的Thr48和取代TRBC1*01或TRBC2*01外显子1的Ser57来形成二硫键。引入半胱氨酸残基以形成二硫键的其他位点还可以是:TRAC*01外显子1的Thr45和TRBC1*01或TRBC2*01外显子1的Ser77;TRAC*01外显子1的Tyr10和TRBC1*01或TRBC2*01外显子1的Ser17;TRAC*01外显子1的Thr45和TRBC1*01或TRBC2*01外显子1的Asp59;TRAC*01外显子1的Ser15和TRBC1*01或TRBC2*01外显子1的Glu15;TRAC*01外显子1的Arg53和TRBC1*01或TRBC2*01外显子1的Ser54;TRAC*01外显子1的Pro89和TRBC1*01或TRBC2*01外显子1的Ala19;或TRAC*01外显子1的Tyr10和TRBC1*01或TRBC2*01外显子1的Glu20。即半胱氨酸残基取代了上述α与β链恒定域中任一组位点。可在本发明TCR恒定域的一个或多个C末端截短最多15个、或最多10个、或最多8个或更少的氨基酸,以使其不包括半胱氨酸残基来达到缺失天然链间二硫键的目的,也可通过将形成天然链间二硫键的半胱氨酸残基突变为另一氨基酸来达到上述目的。
如上所述,本发明的TCR可以包含在其α和β链恒定域的残基间引入的人工链间二硫键。应注意,恒定域间含或不含上文所述的引入的人工二硫键,本发明的TCR均可含有TRAC恒定域序列和TRBC1或TRBC2恒定域序列。TCR的TRAC恒定域序列和TRBC1或TRBC2恒定域序列可通过存在于TCR中的天然链间二硫键连接。
另外,对于稳定性而言,专利文献PCT/CN2016/077680还公开了在TCR的α链可变区与β链恒定区之间引入人工链间二硫键能够使TCR的稳定性显著提高。因此,本发明的高亲和力TCR的α链可变区与β链恒定区之间还可以含有人工链间二硫键。具体地,在所述TCR的α链可变区与β链恒定区之间形成人工链间二硫键的半胱氨酸残基取代了:TRAV的第46位氨基酸和TRBC1*01或TRBC2*01外显子1的第60位氨基酸;TRAV的第47位氨基酸和TRBC1*01或TRBC2*01外显子1的61位氨基酸;TRAV的第46位氨基酸和TRBC1*01或TRBC2*01外显子1的第61位氨基酸;或TRAV的第47位氨基酸和TRBC1*01或TRBC2*01外显子1的第60位氨基酸。优选地,这样的TCR可以包含(i)除其跨膜结构域以外的全部或部分TCRα链,和(ii)除其跨膜结构域以外的全部或部分TCRβ链,其中(i)和(ii)均包含TCR链的可变域和至少一部分恒定域,α链与β链形成异质二聚体。更优选地,这样的TCR可以包含α链可变域和β链可变域以及除跨膜结构域以外的全部或部分β链恒定域,但其不包含α链恒定域,所述TCR的α链可变域与β链形成异质二聚体。
对于稳定性而言,另一方面,本发明TCR还包括在其疏水芯区域发生突变的TCR,这些疏水芯区域的突变优选为能够使本发明TCR的稳定性提高的突变,如在公开号为WO2014/206304的专利文献中所述。这样的TCR可在其下列可变域疏水芯位置发生突变:(α和/或β链)可变区氨基酸第11、13、19、21、53、76、89、91、94位,和/或α链J基因(TRAJ)短肽氨基酸位置倒数第3、5、7位和/或β链J基因(TRBJ)短肽氨基酸位置倒数第2、4、6位,其中氨基酸序列的位置编号按国际免疫遗传学信息系统(IMGT)中列出的位置编号。本领域技术人员知晓上述国际免疫遗传学信息系统,并可根据该数据库得到不同TCR的氨基酸残基在IMGT中的位置编号。
更具体地,本发明中疏水芯区域发生突变的TCR可以是由一柔性肽链连接TCR的α与β链的可变域而构成的高稳定性单链TCR。TCR可变区的CDR区决定了其与短肽-HLA复合物之间的亲和力,疏水芯的突变能够使TCR更加稳定,但并不会影响其与短肽-HLA复合物之间的亲和力。应注意,本发明中柔性肽链可以是任何适合连接TCRα与β链可变域的肽链。本发明实施例1中构建的用于筛选高亲和性TCR的模板链即为上述含有疏水芯突变的高稳定性单链TCR。采用稳定性较高的TCR,能够更方便的评估TCR与SLLMWITQC-HLA-A0201复合物之间的亲和力。
该单链模板TCR的α链可变域及β链可变域的CDR区与野生型TCR的CDR区完全相同。即α链可变域的3个CDR分别为CDR1α:TSINN,CDR2α:IRSNERE,CDR3α:ATDANGKII和β链可变域的3个CDR分别为CDR1β:SGHDY,CDR2β:FNNNVP,CDR3β:ASSLGSNEQY。该单链模板TCR的氨基酸序列(SEQ ID NO:52)及核苷酸序列(SEQ ID NO:53)分别如图7a和7b所示。以此筛选出对SLLMWITQC-HLA A0201复合物具有高亲和性的由α链可变域和β链可变域构成的单链TCR。
本发明中单链模板TCRα链可变域SEQ ID NO:3的1个CDR即CDR3位于SEQ ID NO:3的第90-98位。据此,氨基酸残基编号采用SEQ ID NO:3所示的编号,90A即为CDR3α的第1位A,91T即为CDR3α的第2位T,93A即为CDR3α的第4位A,94N即为CDR3α的第5位N,95G即为CDR3α的第6位G,96K即为CDR3α的第7位K,97I即为CDR3α的第8位I,98I即为CDR3α的第9位I。

通常,可将治疗性组合物制成可注射剂,例如液体溶液或悬液;还可制成在注射前适合配入溶液或悬液中、液体载体的固体形式。
一旦配成本发明的组合物,可将其通过常规途径进行给药,其中包括(但并不限于):眼内、肌内、静脉内、皮下、皮内、或局部给药,优选为胃肠外包括皮下、肌肉内或静脉内。待预防或治疗的对象可以是动物;尤其是人。

本发明的药物组合物还可以缓释剂形式给药。例如,本发明TCR可被掺入以缓释聚合物为载体的药丸或微囊中,然后将该药丸或微囊通过手术植入待治疗的组织。作为缓释聚合物的例子,可例举的有乙烯-乙烯基乙酸酯共聚物、聚羟基甲基丙烯酸酯(polyhydrometaacrylate)、聚丙烯酰胺、聚乙烯吡咯烷酮、甲基纤维素、乳酸聚合物、乳酸-乙醇酸共聚物等,较佳地可例举的是可生物降解的聚合物如乳酸聚合物和乳酸-乙醇酸共聚物。
当本发明的药物组合物被用于实际治疗时,作为活性成分的本发明TCR或TCR复合物或呈递本发明TCR的细胞,可根据待治疗的每个病人的体重、年龄、性别、症状程度而合理地加以确定,最终由医师决定合理的用量。
