Description

抗人PCSK9单克隆抗体
技术领域
本发明为基因工程抗体药物领域,特别是抗人PCSK9的单克隆抗体领域。本发明涉及人源性功能性抗人PCSK9单克隆抗体,以及这类抗体在治疗人PCSK9介导的疾病中的用途。
背景技术
心血管疾病是目前我国首位的死亡原因,其中动脉粥样硬化引起的心脏病、脑卒中和外周动脉疾病是导致死亡的主要原因,而低密度脂蛋白胆固醇(LDL-C)水平升高是动脉粥样硬化性心血管疾病最大的危险因素。他汀类药物是目前降低LDL-C最有效的药物,但是仍有部分患者的血脂水平未能达标,以及有些患者不能耐受他汀类药物。因此,需要寻找他汀以外的强效降胆固醇药物,以降低动脉粥样硬化性心血管疾病的风险。
前蛋白枯草溶菌素转化酶9(proproteinconvertasesubtilisinkexin9,PCSK9),又称为神经凋亡调节转化酶1(neuralapoptosis-regulatedconvertase1,NARC-1)。PCSK9蛋白主要在肝脏中合成和分泌,PCSK9蛋白进入血液循环后,在肝脏与低密度脂蛋白受体(thelow-densitylipoproteinreceptor,LDLR)结合,介导LDLR降解,从而降低肝脏对LDL-C的清除能力,升高血浆LDL-C水平。PCSK9基因敲除的小鼠表现出血浆胆固醇水平大约降低50%,而且使他汀类药物降低血浆胆固醇的灵敏度变高(RashidS,etal2005,ProcNathAcadSci102:5374-5379)。
抗PCSK9单克隆抗体可有效阻止PCSK9与LDL-R结合,从而发挥强效降胆固醇的作用,可用于他汀治疗未达标或他汀不耐受的高胆固醇血症的患者。
目前安进研发的PCSK9抑制剂Repatha(Evolocumab)和赛诺菲/再生元研发的PCSK9抑制剂Praluent(Alirocumab)都已经获得欧洲和美国FDA的批准上市,用于治疗原发性高胆固醇血症、混合型高脂血症和家族性高胆固醇血症。但是本领域仍然需要更多适于治疗患者的改善的抗PCSK9抗体。

具体实施方式
以下实施例仅仅对本发明进行进一步的说明,不应理解为对本发明的限制。
实施例1:各种重组蛋白的制备。
制备抗PCSK9单抗的过程中需要用到多种不同的重组蛋白,包括人PCSK9(huPCSK9,SeqIDNo:1),小鼠PCSK9(moPCSK9,SeqIDNo:2)和猕猴PCSK9(mmPCSK9,SeqIDNo:3),人LDLR胞外区(EGF-AB,SeqIDNo:4),以及重组抗体。而这些蛋白都有大量的翻译后修饰(如:糖基化或二硫键等),因而利用哺乳动物细胞表达系统将更有利于保持重组蛋白的结构和功能。此外,为了方便纯化,非抗体类的重组蛋白在C端添加了His-tag(SeqIDNo:5)或者鼠抗体的Fc段(mFc,SeqIDNo:6)。重组抗体制备时,抗体重链恒定区可以是IgG1亚型(SeqIDNo:7),IgG2亚型(SeqIDNo:8)或者IgG4亚型(SeqIDNo:9),轻链恒定区可以是kappa亚型(SeqIDNo:10)或者Lambda亚型(SeqIDNo:11)。
根据Uniprot数据库的各种目的重组蛋白的氨基酸序列,设计并合成上述各种重组蛋白的基因(包含His-tag或者mFc编码基因)。利用常规的分子生物学技术将合成的各种重组蛋白基因克隆至合适的真核表达载体(如invitrogen公司的pcDNA3.1等),然后利用脂质体(如invitrogen公司的293fectin等)或其它转染试剂(如PEI等)将制备的重组蛋白表达质粒转染入HEK293细胞(如invitrogen公司的HEK293F),在无血清悬浮培养条件下培养3-4天。然后通过离心等方式收获培养上清。
His-tag融合表达的重组蛋白利用金属螯合亲和层析柱(如GE公司的HisTrapFF等)对培养上清中的重组蛋白进行一步纯化。而mFc融合表达的重组蛋白和重组抗体用ProteinA/G亲和层析柱(如GE公司的MabselectSURE等)进行一步纯化。然后利用脱盐柱(如GE公司的Hitrapdesaulting等)将重组蛋白保存缓冲液置换为PBS(pH7.0)或者其它合适的缓冲液。必要时,可以对抗体样品进行过滤除菌,然后分装保存于-20°C。
实施例2:利用噬菌体呈现抗体库技术筛选和优化抗人PCSK9单抗。
以制备的重组huPCSK9-his(以下简写为PCSK9-His)为抗原,参照文献(抗人IL-17单克隆抗体,专利申请号201510097117.0),利用固相筛选策略筛选呈现人单链抗体库的噬菌体,获得多株序列不同但特异性结合人PCSK9的人抗体,包括克隆:S2B8(SeqIDNo:12),S2F5(SeqIDNo:13),S2G1(SeqIDNo:14),S3A12(SeqIDNo:15)。其中重组全抗体S3A12能够有效抑制PCSK9结合重组人LDLR胞外区EGF-AB结构域(图1)。
然后参照文献(抗人IL-17单克隆抗体,专利申请号201510097117.0)利用轻链置换和重链CDRs突变的策略对抗体进行体外亲和力成熟,最终获得四株亲和力提高的抗人PCSK9的单抗,具体序列信息见表1。

实施例3:BIacore3000测定全抗体的亲和力。
Aminecoulingkit和humanantibodycapturekit以及CM5芯片和pH7.4的10×HBS-EP均购自GEHealthcare。
根据试剂盒中的说明书,将抗人FC段的抗体偶联至芯片CM5的表面上,稀释抗体蛋白至合适浓度,保证200RU左右的抗体被抗人Fc的抗体捕获。将huPCSK9设置一系列的浓度梯度(ex.100nm,50nm,25nm,12.5nm,6.25nm,3.125nm,1.5625nm,0nm)流经固定相表面,测定各单克隆抗体的亲和力,用同样的方法测定Evolocumab(SeqIDNo:21,SeqIDNo:22)和Alirocumab(SeqIDNo:23,SeqIDNo:24)的亲和力作为对照。结果如表2所示。

实施例4:抗人PCSK9单克隆抗体竞争PCSK9受体LDLR结合PCSK9。
功能性的抗PCSK9单抗应该能在蛋白水平上阻断LDLR和PCSK9之间的结合,本实施例分析了6种不同抗PCSK9单抗(H4H4,H7B12,H8A7,H8F4,Evolocumab和Alirocumab)抑制LDLR与PCSK9结合的能力。
用5.6ug/ml的PCSK9-his对各单克隆抗体进行梯度稀释,共11个稀释浓度,前6个梯度1:1稀释,后5个梯度1:2稀释,各抗体起始浓度调整为30ug/ml。利用HRP-mouse-anti-hisIgG单抗检测LDLR与PCSK9的结合信号,然后利用GraphPadPrism6进行数据分析和作图(图2)。
实施例5:抗PCSK9单抗在人血清中的稳定性分析。
为了初步分析不同抗PCSK9单抗分子的特异性及血清稳定性,进行了抗PCSK9单抗在人血清中的稳定性分析。此研究包括6种不同抗PCSK9单抗,分别为H4H4,H7B12,H8A7,H8F4,Evolocumab和Alirocumab。取过滤去菌的单抗样品,分别稀释于200ul无菌的正常人混合血清或PBS至终浓度30ug/ml,混匀后置37℃水浴放置12天(288小时)。12天后,利用ELISA分析血清样品(A:Ab/normalhumanserum),PBS样品(B:Ab/PBS)和冻存的单抗样品(C:Ab)与huPCSK9的结合(图3),并分别比较各单抗样品结合huPCSK9能力的变化(A/C)。结果(表3)表明本发明中的四株抗huPCSK9单抗具有好的血清稳定性。
表3:不同处理条件下单抗样品结合huPCSK9能力的变化。
实施例6:抗PCSK9单抗抑制PCSK9诱导HEK293细胞表面LDLR受体的下调。
本实施例研究用悬浮培养于293Freestyle培养基(Invitrogen)的HEK293细胞。将HEK293细胞密度调整至8*10E5cells/ml,接种于24孔板(500ul/孔)。然后按照表4所列方式处理细胞,悬浮培养3h。然后分别收集各孔中细胞,用1%BSA-PBS洗涤2次,然后与FITC-anti-LDLR单抗(SinoBiologicalInc.Cat#10231-R301-F)于冰上孵育45分钟,用PBS洗涤2次后,用BD公司的AccuriC6流式细胞仪分析FITC信号。以未处理的HEK293细胞为对照,比较各种处理后细胞表面LDLR的水平。结果(图4)显示:10ug/ml的PCSK9处理HEK293细胞后导致细胞表明LDLR水平明显下降,而多种抗PCSK9单抗(20ug/ml)能够明显抑制PCSK9诱导的LDLR水平下调。
表4:HEK293细胞的不同处理方式。
实施例7:抗PCSK9单抗抑制PCSK9诱导HEK293细胞摄取LDL-C能力的下调。
