技术背景
白细胞介素-2(IL2)是调节淋巴细胞增殖和活化的细胞因子。它具有133个氨基酸的长度,结构包括四个反平行的两亲性C-螺旋。IL2通过与IL2受体(IL2R)结合介导其作用,所述受体包括多达三个单独的亚单位。所有三个亚单位(白细胞介素-2受体α链(IL2Rα,或CD25)、白细胞介素-2受体β链(IL2Rβ,或CD122)和白细胞介素-2受体γ链(IL2Rγ,或CD132))的缔合产生了三聚体IL2Rαβγ,其为IL2的高亲和力受体。IL2Rβ与IL2Rγ亚单位的缔合产生二聚体受体IL2Rβγ,并被称为中间亲和力IL2R。IL2Rα亚单位形成单体低亲和力IL2受体。IL2Rα的表达参与免疫抑制调节性T细胞(Treg)的扩增;而二聚体IL2Rβγ在IL2Rα不存在的情况下可导致细胞裂解性CD8+T细胞和NK细胞增殖和杀伤。

具体实施方式
IL2一直是有前景的新免疫疗法,但基于野生型人IL2的疗法除了活化效应T细胞和NK细胞以外,还可活化调节性T细胞。IL2对调节性T细胞的活化可阻碍原本可由IL2引发的抗癌反应。因此,需要基于IL2的疗法,其具有减少的调节性T细胞活化和/或效应T细胞、NK细胞或其组合的优先活化。
本文提供了合理设计的IL2Rβ激动剂,其为在IL2Rβ结合区2中具有增强与IL2Rβ的结合的氨基酸取代的工程化的IL2多肽。与野生型IL2相比,工程化的IL2Rβ激动剂提供了增加对NK细胞和效应T细胞刺激的有利方面,但不能增加对调节性T细胞的刺激。因此,工程化的IL2Rβ激动剂可用于调节或活化免疫反应,例如用于治疗癌症。

制造工程化的IL2多肽的方法
工程化的IL2多肽或工程化的IL2融合多肽可以通过本领域公知的遗传或化学方法以及通过下面实施例中公开的方法来制备。遗传方法可以包括,例如,编码多肽的DNA的位点特异性诱变、PCR和基因合成。预期的核苷酸变化可以通过测序来验证。天然IL2的核苷酸序列已由Taniguchi等人(Nature 302,305-10(1983))描述,并且编码天然人IL2的核酸可从例如美国典型培养物保藏中心(Rockville Md.)获得。
工程化的IL2多肽或工程化的IL2融合多肽可以例如通过重组产生或固态肽合成获得。对于重组产生,可以分离编码工程化的IL2多肽或工程化的IL2融合多肽的多核苷酸,并将其插入一个或多个载体,用于在宿主细胞中克隆和/或表达。此类多核苷酸可以通过常规方法容易地分离和测序。在某些实施方案中,提供了包含一种或多种本公开的多核苷酸的载体,诸如表达载体。本领域技术人员公知的方法可用于构建含有编码工程化的IL2多肽或工程化的IL2融合多肽的编码序列以及适当的转录/翻译控制信号的表达载体。这些方法包括体外重组DNA技术、合成技术和体内重组/基因重组。参见,例如,Maniatis等人,MOLECULAR CLONING:A LABORATORY MAN UAL(第4版),Cold Spring Harbor Laboratory,N.Y.(2012);以及Ausubel等人,CURRENT PROTOCOLS IN MOLECULAR BIOLOG Y,GreenePublishing Associates and Wiley Interscience,N.Y(1993)中描述的技术。表达载体可以是质粒、病毒的一部分,或者可以是核酸片段。表达载体包括表达盒,编码工程化的IL2多肽或工程化的IL2融合多肽的多核苷酸(即,编码区)可被克隆到所述表达盒中而与启动子和/或其它转录或翻译控制元件可操作地关联。如本文中所用,“编码区”是由翻译成氨基酸的密码子组成的核酸的一部分。虽然“终止密码子”(TAG、TGA或TAA)没有翻译成氨基酸,但如果存在,其可被认为是编码区的一部分,但任何侧翼序列,例如启动子、核糖体结合位点、转录终止子、内含子、5’和3’非翻译区等,都不是编码区的一部分。两个或更多个编码区可以存在于单个多核苷酸构建体中,例如,存在于单个载体上,或者存在于单独的多核苷酸构建体中,例如,存在于单独的(不同的)载体上。此外,任何载体可以包含单个编码区,或者可以包含两个或更多个编码区,例如,本文公开的载体可以编码一个或多个多蛋白,所述多蛋白通过蛋白水解切割在翻译后分离成最终的蛋白质或通过蛋白水解切割共翻译分离成最终的蛋白质。另外,本公开的载体、多核苷酸或核酸可以编码与编码本文公开的多肽或其变体或衍生物的第一或第二多核苷酸融合或未与其融合的异源编码区。异源编码区包括但不限于特化的元件或基序,诸如分泌信号肽或异源功能域。可操作的关联是当基因产物(例如,多肽)的编码区以将基因产物的表达置于一个或多个调节序列的影响或控制之下的方式与一个或多个调控序列关联时。如果启动子功能的诱导导致编码所需基因产物的mRNA的转录,并且如果两个DNA片段之间的键联性质不干扰表达调控序列指导基因产物表达的能力或干扰DN A模板被转录的能力,则两个DNA片段(诸如多肽编码区和与其相关联的启动子)是“可操作地关联的”。因此,如果启动子能够影响编码多肽的核酸的转录,那么启动子区域将可操作地与该核酸相关联。启动子可以是细胞特异性启动子,其仅在预定的细胞中指导DNA的大量转录。除了启动子之外,其它转录控制元件,例如增强子、操纵子、阻遏物和转录终止信号也可与多核苷酸可操作地关联,以指导细胞特异性转录。本文公开了合适的启动子和其它转录控制区。本领域技术人员已知多种转录控制区。这些包括但不限于在脊椎动物细胞中起作用的转录控制区,诸如但不限于来自巨细胞病毒(例如,立即早期启动子,与内含子-A连接)、猿猴病毒40(例如,早期启动子)和逆转录病毒(例如,劳斯肉瘤病毒)的启动子和增强子区段。其它转录控制区包括来源于脊椎动物基因诸如肌动蛋白、热休克蛋白、牛生长激素和兔β-珠蛋白的那些转录控制区,以及能够控制真核细胞中基因表达的其它序列。其它合适的转录控制区包括组织特异性启动子和增强子以及诱导型启动子(例如,四环素类诱导型启动子)。类似地,本领域普通技术人员已知多种翻译控制元件。这些包括但不限于核糖体结合位点、翻译起始和终止密码子,以及来源于病毒系统的元件(特别是内部核糖体进入位点或IRES,也称为CITE序列)。表达盒还可以包括其它特征,诸如复制起点,和/或染色体整合元件,诸如逆转录病毒长末端重复序列(LTR),或腺相关病毒(AAV)反向末端重复序列(ITR)。
本公开的多核苷酸和核酸编码区可以与编码分泌肽或信号肽的附加编码区相关联,所述附加编码区指导由本公开的多核苷酸编码的多肽的分泌。例如,如果需要分泌工程化的IL2多肽或工程化的IL2融合多肽,则可以将编码信号序列的DNA置于编码工程化的IL2多肽或工程化的IL2融合多肽的成熟氨基酸的核酸的上游。本领域普通技术人员知道,脊椎动物细胞分泌的多肽通常具有与多肽的N末端融合的信号肽,所述信号肽从翻译的多肽上被切割下来,产生分泌或“成熟”形式的多肽。例如,天然人IL2在多肽的N末端与20个氨基酸的信号序列一起翻译,所述信号序列随后被切掉,产生成熟的133个氨基酸的人IL2。在一些实施方案中,使用天然信号肽,例如IL2信号肽或免疫球蛋白重链或轻链信号肽,或该序列的功能衍生物,所述功能衍生物保留指导与其可操作地关联的多肽分泌的能力。
在一些实施方案中,编码工程化的IL2多肽或工程化的IL2融合多肽的多核苷酸还包括编码有利于纯化的序列(例如,组氨酸标签)或用于在编码工程化的IL2多肽或工程化的IL2融合多肽的多核苷酸内或末端标记工程化的IL2多肽或工程化的IL2融合多肽的DNA序列。
在某些实施方案中,提供了包含一种或多种编码工程化的IL2多肽或工程化的IL2融合多肽的多核苷酸的宿主细胞。在某些实施方案中,宿主细胞包含一种或多种编码工程化的IL2多肽或工程化的IL2融合物的载体。宿主细胞可以是可用于产生工程化的IL2多肽或工程化的IL2融合多肽的任何类型的细胞系统。此类细胞可用编码工程化的IL2多肽或工程化的IL2融合物的特定表达载体转染或转导,并且可以生长大量含有载体的细胞以用于接种大规模发酵罐,以获得足够数量的编码工程化的IL2多肽或工程化的IL2融合物用于临床应用。合适的宿主细胞包括原核微生物,诸如大肠杆菌(E.Coli),或各种真核细胞,或各种真核细胞,诸如中国仓鼠卵巢细胞(CHO)、昆虫细胞等。例如,可以在细菌中产生多肽,特别是在不需要糖基化时。表达后,可将多肽以可溶性级分从细菌细胞中分离出来,并可进一步纯化。除了原核生物之外,真核微生物诸如丝状真菌或酵母是适合于编码抗体的载体的克隆性或表达宿主,包括其糖基化途径已被“人源化”从而导致产生具有部分或完全人糖基化模式的多肽的真菌和酵母菌株。用于表达(糖基化的)多肽的适合宿主细胞也源自多细胞生物体(无脊椎动物和脊椎动物)。无脊椎动物细胞的实例包括植物和昆虫细胞。已经鉴定出许多杆状病毒株,其可以与昆虫细胞结合使用,特别是用于转染草地贪夜蛾(Spodopterafrugiperda)细胞。也可以利用植物细胞培养物作为宿主。参见,例如,美国专利第5,959,177号、第6,040,498号、第6,420,548号、第7,125,978号和第6,417,429号(其描述了用于在转基因植物中生产抗体的PLANTIBODIESTM技术)。也可使用脊椎动物细胞作为宿主。例如,适于在悬浮液中生长的哺乳动物细胞系可能是有用的。有用的哺乳动物宿主细胞系的其它实例是由SV40转化的猴肾CV1细胞系(COS-7);人胚胎肾系(如例如Graham等人,J Gen Virol36,59(1977)中所述的293或293T细胞)、幼仓鼠肾细胞(BHK)、小鼠支持细胞(如,例如Mather,Biol Reprod 23,243-251(1980)中所述的TM4细胞)、猴肾细胞(CV1)、非洲绿猴肾细胞(VERO-76)、人宫颈癌细胞(HELA)、犬肾细胞(MDCK)、buffalo大鼠肝细胞(BRL 3A)、人肺细胞(W138)、人肝细胞(Hep G2)、小鼠乳腺肿瘤细胞(MMT060562)、TRI细胞(如,例如,Mather等人,Annals N.Y.Acad Sci 383,44-68(1982)中所描述的)、MRC 5细胞和FS4细胞。其它有用的哺乳动物宿主细胞系包括中国仓鼠卵巢(CHO)细胞,包括dhfr-CHO细胞(Urlaub等人,Proc Natl Acad Sci USA 77,4216(1980));和骨髓瘤细胞系诸如YO、NS0、P3X63和Sp2/0。关于某些适于蛋白质产生的哺乳动物宿主细胞系的综述,参见,例如,Yazaki和Wu,Methods inMolecular Biology,第248卷(B.K.C.Lo,编辑,Humana Press,Totowa,N.J.),第255-268页(2003)。宿主细胞包括培养细胞,例如,哺乳动物培养细胞、酵母细胞、昆虫细胞、细菌细胞和植物细胞,仅举几个实例,还包括转基因动物、转基因植物或培养的植物或动物组织内包含的细胞。在一个实施方案中,宿主细胞是真核细胞,优选哺乳动物细胞,诸如中国仓鼠卵巢(CHO)细胞、人胚胎肾(HEK)细胞或淋巴样细胞(例如,Y0、NS0、Sp20细胞)。

本文所述的工程化的IL2多肽和工程化的IL2融合多肽可以以有效实现预期目的的量使用。为了用于治疗或预防疾病状况,以治疗有效量施用工程化的IL2多肽或工程化的IL2融合多肽或其药物组合物。治疗有效量的确定,尤其是根据本文提供的细节的确定,在本领域技术人员的能力范围内。
对于全身性施用,治疗有效量最初可以从体外测定诸如细胞培养测定中来估计。然后可在动物模型中配制剂量来实现包括如在细胞培养中测定的IC50的循环血浆浓度范围。这样的信息可用于更准确地测定人中的有用剂量。还可使用本领域公知的技术,从体内数据(例如,动物模型)估计初始剂量。基于动物数据,本领域普通技术人员可以容易地优化向人的施用。剂量量和间隔可各自被调节,以提供足以维持治疗效果的工程化的IL2多肽和工程化的IL2融合多肽的血浆水平。血浆中的水平可以例如通过HPLC来测量。

IL2Rβ激动剂克隆的选择和鉴定
mRNA展示技术平台被用于从三个IL2诱变文库鉴定IL2Rβ激动剂。首先将DNA文库转录成mRNA文库,然后通过嘌呤霉素通过接头通过共价偶联将其翻译成mRNA-IL2突变体融合文库。然后将文库纯化并转化为mRNA/cDNA融合文库(参见,例如,美国专利第6,258,558号,据此通过引用并入)。首先用人IgG(阴性蛋白)对融合文库进行反向选择以去除非特异性结合物,然后进行反向选择以去除IL2Rα结合剂,随后针对捕获在蛋白G磁珠上的重组IL2Rβ/Fc蛋白进行选择。回收IL2Rβ结合剂并通过PCR扩增进行富集。总共进行了五轮选择来产生与IL2Rβ结合的高度富集的工程化的IL2突变体。
经五轮选择后,将富集的文库克隆到细菌周质表达载体pET22b中,并将其转化到TOP10感受态大肠杆菌细胞中。每种工程化的IL2分子被工程化为具有C末端flag标签和6xHIS标签以用于纯化和测定检测。汇集来自TOP10细胞的克隆,制备miniprep DNA,随后将其转化到大肠杆菌Rosetta II菌株中进行表达。挑选、生长单个克隆,并用0.25mM IPTG在96孔平板中诱导表达。在30℃下诱导16至24小时后收集上清液,用于鉴定结合剂的测定。

接下来筛选了单个克隆的IL2Rβ结合。IL2Rβ结合筛选ELISA被开发用来鉴定单个工程化的IL2突变体。简言之,分别以2μg/mL的于1X PBS中的终浓度用总体积为每孔50μL的人Fc和人IL2Rβ固定96孔平板。将平板在4℃孵育过夜,然后用每孔200μL的superblock封闭1小时。将100μl上清液加入到Fc和IL2Rβ固定的孔中,并振荡孵育1小时。通过加入50μL的以1:5000于1X PBST中稀释的抗Flag HRP来检测工程化的IL2突变体结合。在每一步之间,在洗板机中用1X PBST洗涤平板三次。然后用50μL TMB底物对平板显影5分钟,并通过加入50μL 2N硫酸停止显影。使用Biotek平板读数器在OD450 nm处读取平板,并分析结合和选择性。用Prism8.1软件绘制表达与IL2Rβ结合的相关性。
从文库5中鉴定出高IL2Rβ结合克隆(显示在垂直OD450 nm截止线的右侧),以进一步表征为工程化的IL2Rβ激动剂(图6)。克隆的IL2Rβ结合活性通常与克隆的表达水平相关。与IL2 WT相比,IL2Rβ结合区2的多重序列比对揭示了高度保守和高度变化的氨基酸,以及独立鉴定多次的克隆序列(图7)。从文库4和6中没有鉴定出特异性IL2Rβ结合克隆。
