Abstract
本发明涉及获得包含登革病毒血清型的衣壳蛋白的药物组合物,其能够在受者中诱导针对病毒攻击的保护性免疫应答,而不诱导抗体依赖性增强现象。
Description
本发明涉及生物技术和制药工业领域,特别是涉及获得能够诱导针对登革病毒(从现在开始称为DEN)感染的免疫应答的蛋白质,同时避免在重新感染这种病毒的个人中描述的抗体依赖性增强现象。
登革热(DF)和登革出血热(DHF)作为健康问题而获得越来越大的重要性,其影响几个热带和亚热带地区的国家。登革病毒已在超过100个国家中发现,并且估计有2500百万人生活在危险区域内。每年报道50-100百万例DF和250000-500000例DHF。(Guzmán M.G.和KouríG.2002.Dengue:an update.Lancet Infect.Dis.2:33-42)。
这种疾病的致病剂是黄病毒科黄病毒属的登革病毒,所其通过埃及伊蚊(Aedes aegypti)传播(Leyssen P.,De Clerco E.,NeytsJ.2000.Perspectives for the treatment of infections withFlaviviridae.Clin.Microbiol.Rev.13:67-82)。
迄今为止已报道了可以在相同区域中传播的4种血清型。登革病毒是正RNA包被病毒,其基因组仅包含1个读码框。该RNA被翻译成多蛋白,所述多蛋白被加工成3个结构蛋白和7个非结构蛋白。(Russell P.K.,Brandt W.E.,Dalrymple J.M.1980.Chemical andantigenic structure of flaviviruses.The togaviruses:biology,structure,replication.Schelesinger R.W.(ed.).503-529)。
已进行多个流行病学调查以确定造成登革疾病的最严重形式的危险因素。它的特征在于高热、液体外渗、出血和最终地登革休克。(Gubler D.J.1998.Dengue and Dengue Hemorrhagic Fever.Clin.Microbiol.Rev.11:480-496)。最重要的危险因素之一是经由异源血清型的继发感染。不存在不同血清型感染间的交叉保护。(KouríG.,Guzmán M.G.,Bravo J.,Trina C.1989.Dengue hemorrhagicfever/dengue shock syndrome:lessons from the Cuban epidemic.WHO Bulletin OMS.67:375-380)。
存在几种假设以解释这种现象。最重要的一种是抗体依赖性增强。(Halstead S.B.,Scanlon J.E.,Umpaivit P.,Udomsakdi S.1969.Dengue and Chikungunya virus infection in man in Thailand,1962-1964.IV.Epidemiologic studies in the Bangkokmetropolit anar ea.Am.J.Trop.Med.Hyg.18:997-1021)。
根据初步研究,提出DEN病毒在来自患者血液的外周单核细胞中更大量地复制,所述患者已经历该病毒的先前感染(Halstead S.B.,O’Rourke E.J.,Allison A.C.1977.Dengue viruses and mononuclearphagocytes.II.Identity of blood and tissue leukocytessupporting in vitro infection.J.Exp.Med.146:218-229)。后来,证实残留抗体负责这种效应(Morens DM,Halstead SB,Marchette NJ.1987.Profiles of antibody-dependent enhancementof dengue virus type 2 infection.Microb Pathog.Oc t;3(4):231-7)。
在其中不存在中和的抗体特异性或浓度的条件下,抗体-病毒复合物可以被在膜中呈现Fcγ受体的细胞如单核细胞和巨噬细胞内在化。称为抗体依赖性增强(antibody depend enhancement,ADE)的这种机制在继发感染期间出现(Morens DM,Halstead SB,Marchette NJ.1987.Profiles of antibody-dependent enhancement of denguevirus type 2 infection.Microb Pathog.Oct;3(4):231-7;Kliks S.C.,Nimmannitya S.,Nisalak A.,Burke D.S.1988.Evidencethat maternal dengue antibodies are important in thedevelopment of dengue hemorrhagic fever in infants.Am.J.Trop.Med.Hyg.38:411-419)。
Halstead等人(Halstead S.B.,Scanlon J.E.,Umpaivit P.,Udomsakdi S.1969.Dengue and Chikungunya virus infection inman in Thailand,1962-1964.IV.Epidemiologic studies in theBangkok metropolitan area.Am.J.Trop.Med.Hyg.18:997-1021)在泰国曼谷进行的3年研究中报道,在儿童中由于DEN感染的住院指数在7-8个月大的那些中达到最大。这些指数是在1-3个月的儿童中观察到的4-8倍,并且是在3岁儿童中的2倍。Kliks等人(KliksS.C.,Nimmannitya S.,Nisalak A.,Burke D.S.1988.Evidence thatmaternal dengue antibodies are important in the development ofdengue hemorrhagic fever in infants.Am.J.Trop.Med.Hyg.38:411-419)确定了针对DEN-2的母体中和抗体滴度与具有由同源病毒感染引起的DHF的13位儿童的年龄之间的关联。结果显示,当母体抗体水平减少至亚中和水平时,出现该病毒感染的严重病例。这些数据与这样的假设相一致,该假设为母体抗体具有双重作用,即首先防护和随后刺激DHF发展。
尽管具有这种免疫学现象,但现今全世界最先进的疫苗候选物基于包含包膜蛋白的4种不同血清型的减毒病毒。这些候选物在人志愿者中能够诱导针对暴露的蛋白质(PrM/M和包膜)的潜在扩大性抗体和针对4种病毒血清型的保护性中和抗体。(Kanesa-thasan N.,SunW.,Kim-Ahn G.,Van Albert S.,Putnak J.R.,King A.,Raengsakulsrach B.,Christ-Schmidt H.,Gilson K.,ZahradnikJ.M.,Vaughn D.W.,Innis B.L.,Saluzzo J.F.y Hoke C.H.2001.Safety and immunogenicity of attenuated dengue virus vaccines(Aventis Pasteur)in human volunteers.Vaccine.19:3179-3188)。
尽管诱导了增强抗体,但是免疫接种后高水平的中和抗体仍可以防止病毒复制。当就中和抗体而言对于疫苗中的4种血清型的总血清转化未获得或者在血液中减少至低水平时,该问题可以出现,并且随后个体将变得对于由其保护性抗体不存在的病毒血清型引起的严重继发感染易感。事实上,已在猴和人中进行了几种测试以确定疫苗制剂中的病毒量。(Guirakhoo F.,Arroyo J.,Pugachev K.V.,MillerC.,Zhang Z.-X.,Weltzin R.,Georgakopoulos K.,Catalan J.,Ocran S.,Soike K.,Raterree M.,Monath T.P.2001.Construction,safety,and immunogenicity in nonhuman primates of a chimericyellow fever-dengue viruste travalent vaccine.J.Virol.75:7290-7304)。
在某些情况下,未获得关于4种血清型的血清转化平衡(Sabchareon A,Lang J,Chanthavanich P,Yoksan S,Forrat R,Attanath P,Sirivichayakul C,Pengsaa K,Pojjaroen-Anant C,Chokejindachai W,Jagsudee A,Saluzzo JF,Bhamarapravati N.2002.Safety and immunogenicity of tetravalent live-attenuateddengue vaccines in Thai adult volunteers:role of serotypeconcentration,ratio,and multiple doses.Am J Trop Med Hyg.66(3):264-72)。此外,在儿童中对于就中和抗体而言的总血清转化必需施用高达3次剂量的减毒疫苗,并且这些是否将长期持续仍是未知的。(Sabchareon A,Lang J,Chanthavanich P,Yoksan S,Forrat R,Attanath P,Sirivichayakul C,Pengsaa K,Pojjaroen-Anant C,Chambonneau L,Saluzzo JF,BhamarapravatiN..2004.Safety and immunogenicity of a three dose regimen oftwo tetravalent live-attenuated dengue vaccines in five-totwelve-year-old Thai children.Pediatr Infect Dis J.;23(2):99-109)。在包含登革病毒的包膜蛋白的疫苗制剂中,从而在开发中的疫苗候选物中,这是最值得怀疑的关注之一。
目前在I/II期中的减毒疫苗的另一个缺点是安全性。已在几项研究中证实了,第一次剂量后,在成人和儿童中存在不良反应例如发热、肌痛、瘀斑和头痛(Sabchareon A,Lang J,Chanthavanich P,YoksanS,Forrat R,Attanath P,Sirivichayakul C,Pengsaa K,Po.jjaroen-Anant C,Chambonneau L,Saluzzo JF,BhamarapravatiN.2004.Safety and immunogenicity of a three dose regimen oftwo tetravalent live-attenuated dengue vaccines in five-totwelve-year-old Thai children.Pediatr Infect Dis J.;23(2):99-109)。一般而言,可能出现与活疫苗潜在相关的毒力回复现象。
在新的备选方案的研究中,已开发了通过重组方法获得的基于包膜蛋白或其片段的疫苗候选物的不同变体。这些重组候选物避免了与活病毒接种相关的安全性问题,并且如果没有诱导针对4种血清型的平衡应答,那么能够使个体致敏(Velzing J,Groen J,Drouet MT,van Amerongen G,Copra C,Osterhaus AD,Deubel V.1999.Inductionof protective immunity against Dengue virus type 2:comparisonof candidate live attenuated and recombinant vaccines.Vaccine.Mar 17;17(11-12):1312-20)。另一方面,这些候选物需要强效的佐剂--关于其在人中的使用仍未获得批准--以刺激血清型特异性的合适的保护性免疫应答(Hermida L,Rodriguez R,Lazo L,SilvaR,Zulueta A,Chinea G,Lopez C,Guzman MG,Guillen G.2004.A dengue-2 Envelope fragment inserted within the structure ofthe P64k meningococcal protein carrier enables a functionalimmune response against the virus in mice.J Virol Methods.2004Jan;115(1):41-9)。
中和抗体的体液应答已在动物中得到广泛研究,并且其保护效应已得到证实。在登革热中作为保护机制的细胞毒性细胞免疫应答仍未深入探究。相反地,存在几个报道,其中证实了细胞应答的诱导与疾病的最严重形式之间的关联(Rothman A.L.y Ennis F.A.1999.Immunopathogenesis of Dengue Hemorragic Fever.Virology.257:1-6)。这些研究基于在显示出DHF的那些个体中存在高水平的激活的T-细胞(Green S,Pichyangkul S,Vaughn DW,Kalayanarooj S,Nimmannitya S,Nisalak A,Kurane I,Rothman AL,Ennis FA.1999.Early CD69 expression on peripheral blood lymphocytes fromchildren with dengue hemorrhagic fever.J Infect Dis.180(5):1429-35)。
已报道T-细胞表位主要在非结构蛋白中(Kurane I,Zeng L,Brinton MA,Ennis FA.1998.Definition of an epitope on NS3recognized by human CD4+ cytotoxic T lymphocyte clonescross-reactive for dengue virus types 2,3,and 4.Virology.1998 Jan 20;240(2):169-74),但也存在于包膜和衣壳蛋白中(Bukowski,J.F.,I.Kurane,C.-J.Lai,M.Bray,B.Falgout和F.A.Ennis.1989.Dengue virus-specific cross-reactive CD8human cytotoxic T lymphocytes.J.Virol.63:5086 5091;Gagnon S.J.,Zeng W.,Kurane I.,Ennis F.A.1996.Identification of two epitopes on the dengue 4 virus capsidprotein recognized by a serotype-specific and a panel ofserotype-cross-reactive human CD4+ cytotoxic T-lymphocyteclones.J Virol.70:141-147)。然而,通过仅诱导细胞免疫应答的这些蛋白质中的一些蛋白质的保护特性仍未得到证实。
在避免免疫增强现象的疫苗候选物的研究中,已进行了使用非结构蛋白NS1和NS3的研究。在NS1的情况下,在用重组蛋白质免疫的小鼠中已达到了一定水平的保护。通过ADCC机制,使用包含NS1基因的裸露DNA已获得了类似结果(Wu SF,Liao CL,Lin YL,Yeh CT,Chen LK,Huang YF,Chou HY,Huang JL,Shaio MF,Sytwu HK.2003.Evaluation of protective efficacy and immune mechanisms ofusing a non-structural protein NS1 in DNA vaccine against dengue2 virus in mice.Vaccine.Sep 8;21(25-26):3919-29)。然而,还存在这样的报道,即由于诱导识别人内皮细胞的抗体,它们可能涉及自身免疫现象(Chiou-Feng Lin,Huan-Yao Lei,Ai-Li Shiau,Hsiao-Sheng Liu,Trai-Ming Yeh,Shun-Hua Chen,Ching-Chuan Liu,Shu-Chen Chiu和Yee-Shin Lin.2002.Endothelial Cell ApoptosisInduced by Antibodies against Dengue Virus nonstructuralProtein l via Production of Nitric Oxide.J.Immunol.657-664)。此外,存在使用包含NS3基因的裸露DNA制剂获得了保护的报道;然而,证实了这种保护由产生的抗体介导,因为使用被动免疫接种获得了相同的保护(Tan CH,Yap EH,Singh M,Deubel V,Chan YC.1990.Passive protection studies in mice with monoclonal antibodiesdirected against the non-struetural protein NS3 of dengue 1virus.J Gen Virol.1990 Mar;71(Pt 3):745-9)。此外,值得注意的是这样的假设,即基于NS3蛋白表位的研究,对于异源病毒感染来说细胞应答可以潜在地有害(Zivny J,DeFronzo M,Jarry W,Jameson J,Cruz J,Ennis FA,Rothman AL.1999.Partial agonisteffect influences the CTL response to a heterologous denguevirusserotype.J Immunol.Sep1;163(5):2754-60)。
在登革病毒的衣壳蛋白的情况下,没有报道在使用致死登革病毒的攻击中具有保护的证据。关于相关的黄病毒,公开了其中作者用包含日本脑炎(JE)衣壳蛋白的基因的裸露DNA制剂接种小鼠的报道。这种制剂在小鼠中不诱导针对使用致死JE攻击的保护性应答,尽管证实了细胞毒性应答(Konishi E,Ajiro N,Nukuzuma C,Mason PW,Kurane I.2003.Comparison of protective efficacies of plasmidDNAs encoding Japanese encephalitis virus proteins that induceneutralizing antibody or cytotoxic T lymphocytes in mice.Vaccine.Sep 8;21(25-26):3675-83)。
使用重组衣壳蛋白的保护仅在人乳头瘤病毒的情况下得到证实。然而,已提出它关于其他病毒如丙型肝炎病毒的保护作用。不过,在所有情况下,它们是慢性感染或肿瘤,其中细胞的细胞毒性应答是免疫系统清除病毒感染的唯一手段(Duenas-Carrera S,Alvarez-Lajonchere L,Alvarez-Obregon JC,Herrera A,LorenzoLJ,Pichardo D,Morales J.2000.A truncated variant of thehepatitis Cvirus core induces a slow but potent immune responsein mice following DNA immunization.Vaccine.Nov 22;19(7-8):992-7;Suzich JA,Ghin SJ,Palmer-Hill FJ,等人,1995.Systemicimmunization with papillomavirus L1 protein completelyprevents the development of viral mucosal papillomas.Proc NatlAcad Sci USA;92:11553-57)。这些疾病与在人中的登革感染所显示的急性特征不一致(Vaughn D.W.,Green S.,Kalayanarooj S.,Innis B.L.,Nimmannitya S.,Suntayakorn S.,Endy T.P.,Raengsakulrach B.,Rothman A.L.,Ennis F.A.y Nisalak A.2000.Dengue viremia titer,antibody response pattern,and virusserotype correlate with disea seseverity.J Infect Dis.181:2-9)。
登革病毒的衣壳蛋白具有9-12kDa(112-127个氨基酸)的分子量,并且具有显著的碱性特征,因为它的25%氨基酸是精氨酸和赖氨酸。由于多阳离子肽做到这点的能力,这些氨基酸的存在可以有利于向免疫系统呈递抗原。(Lingnau K.,Egyed A.,Schellack C.,MattnerF,Buschle M.,Schmidt W.2002.Poly-1-arginine synergizeswith oligodeoxynucleotides containing CpG-motifs(CpG-ODN)for enhanced and prolonged immune responses and prevents theCpG-ODN-induced systemic release of pro-inflammatory cytokines.Vaccine.20:3498-3508)。该蛋白质完全位于病毒粒子结构内而无任何暴露区域(Kuhn RJ,Zhang W,Rossmann MG,Pletnev SV,CorverJ,Lenches E,Jones CT,Mukhopadhyay S,Chipman PR,Strauss EG,Baker TS,Strauss JH.2002.Structure of dengue virus:implications for flavivirus organization,maturation,andfusion.Cell.Mar 8;108(5):717-25)。
Jones等人(Christopher T.Jones,Lixin Ma,John W.Burgner,Teresa D.Groesch,Carol B.Post和Richard J.Kuhn.2003.Flavivirus Capsid Is a Dimeric Alpha-Helical Protein.Journalof Virology,第7143-7149页,第77卷,No.12)纯化了在大肠杆菌(Escherichia coli)中通过重组方法获得的VD2的衣壳蛋白,并且证实这种蛋白质在不存在核酸的情况下在溶液中的表现如同二聚体。它的二级结构主要是α-螺旋的形式,并且由这些螺旋中的4个组成,在C-末端发现长度更长的螺旋。N-末端不呈现确定的结构,并且它的删除不影响该蛋白质的结构完整性。
本发明首次描述了,通过重组方法在大肠杆菌中获得且仅具有40%纯度的DEN-2病毒的衣壳能够在小鼠中诱导针对用致死DEN-2病毒的攻击的保护性免疫应答。证实了这种高度纯化的蛋白质保留了其保护能力,所述保护能力在用颗粒形式的分子免疫接种小鼠中被超过。此外,证实了所达到的保护由CD8+T-细胞介导,考虑到目前为止报道的关于衣壳的T-细胞表位由CD4+T细胞识别,这是新型元素(Gagnon SJ,Zeng W,Kurane I,Ennis FA.1996.Identificationof two epitopes on the dengue 4 virus capsid protein recognizedby a serotype-specific and a panel of serotype-cross-reactivehuman CD4+cytotoxic T-lymphocyte clones.J Virol.70(1):141-7;Simmons CP,Dong T,Chau NV,Dung NT,Chau TN,Thao leTT,Dung NT,Hien TT,Rowland-Jones S,Farrar J.2005.EarlyT-cell responses to dengue virus epitopes in Vietnamese adultswith secondary dengue virus infections.J Virol.79(9):5665-75)。此外,将这种重组分子与PD5蛋白相混合,所述PD5蛋白由脑膜炎奈瑟氏球菌(Neisseria meningitidis)的P64k蛋白和登革-2病毒的包膜蛋白的III结构域形成。这种融合蛋白能够产生高度血清型特异性的、保护性的和中和性的免疫应答,具有产生抗体依赖性增强现象的低可能性(Hermida L,Rodriguez R,Lazo L,Silva R,Zulueta A,Chinea G,Lopez C,Guzman MG,Guillen G.2004.Adengue-2 Envelope fragment inserted within the structure of theP64k meningococcal protein carrier enables a functional immuneresponse against the virus in mice.J Virol Methods.2004 Jan;115(1):41-9)。
还描述了获得通过使衣壳蛋白与包膜蛋白的III结构域融合而形成的遗传构建体以达到相同目的。因此,其中衣壳与DEN-2的III结构域相组合的这2种制剂在小鼠中产生比单独的衣壳更高的淋巴组织增生性应答,并且另外,产生比单独的PD5更高的血清型特异性抗体应答。后面这个结果证实登革病毒的衣壳蛋白在通过异源抗原的抗体产生中的免疫增强能力,这是对于来自其他病毒如乙型肝炎病毒的其他重组衣壳所描述的现象(Alvarez JC,Guillén G.Formulationscontaining virus like particles as immunoenhancers by mucosalroute.Cuban office of the Industrial property.CU 1998/183)。
发明详述
本发明的目的是获得相应于登革病毒的衣壳蛋白的重组蛋白质,所述重组蛋白质当在小鼠中接种时产生针对用致死病毒感染的保护性应答。
将编码登革病毒的衣壳蛋白的基因插入包含噬菌体T5启动子的质粒中。用该重组质粒转化的细胞XL-1Blue表达高水平的所得到的蛋白质。
将这种蛋白质大约纯化至40%的纯度,并且在氢氧化铝中佐剂化(adjuvated)以在Balb/c小鼠中进行接种。最后1次剂量后1个月,测量抗病毒抗体应答。同时测定在体外用登革病毒刺激的脾中的淋巴组织增生性应答。结果,没有诱导抗病毒抗体,而是检测到显著的淋巴组织增生性应答。平行地,在未出血的小鼠中,进行保护测定法。接种相应于100LD50的登革病毒的致死剂量,并在21天期间观察疾病症状和死亡。结果,在经免疫的小鼠中获得44.4%的存活,而在阴性对照组中所有小鼠都死亡。这是通过仅用衣壳蛋白的免疫接种而产生针对登革病毒的保护性应答的第一个证据。
随后,进行高分辨率的纯化过程,获得纯度>95%的重组蛋白质。
2种制剂即半纯化的和纯化的制剂通过HPLC进行分析,以了解每种样品中的蛋白质聚集状态。在半纯化的制剂中检测到具有更少保留时间的级分,而在纯化的样品中检测到相应于二聚体形式的分子的保留时间。
为了在纯化的变体中获得聚集状态,进行使用少量寡核苷酸的体外颗粒化过程。由于该过程,获得了直径21nm的颗粒。
均具有超过95%纯度的二聚化和颗粒化的制剂在小鼠中进行接种。二聚化制剂用弗氏佐剂和氢氧化铝进行佐剂化,而颗粒化的变体仅用氢氧化铝进行佐剂化。
类似于半纯化的制剂,检测到高水平的淋巴组织增生。在保护测定法中,用由弗氏佐剂和氢氧化铝佐剂化的二聚化制剂分别获得40和20%的存活;然而,用氢氧化铝佐剂化的颗粒化蛋白质诱导更高的保护百分比。
这些结果连同用半纯化的蛋白质获得的那些结果一起显示了衣壳蛋白在Balb/c小鼠中诱导保护性应答的能力,并且证实了颗粒化形式的蛋白质的优越性,使得其可连同作为佐剂的氢氧化铝一起在未来用于人类。此外,未诱导抗病毒应答将消除抗体依赖性增强现象,其作为关于出现疾病的最严重形式(登革出血热)的危险因素。
为了确定保护的可能机制(由于其证实不存在,所以所述机制与抗体的诱导无关),进行CD8+细胞耗竭的研究。结果,用每种变体的纯化蛋白质而达到的保护依赖于呈现这种标记物的细胞的存在,因为当消除它们时,诱导的保护效应消失。
类似地,进行研究以了解颗粒化的重组衣壳与诱导体液应答的抗原的组合是否不影响淋巴组织增生性应答的产生,并且计数能够促成免疫应答的这2种分支的免疫原混合物。为此,在小鼠中接种衣壳的纯化的颗粒化变体和包含登革-2病毒的包膜蛋白的III结构域的融合蛋白,所述小鼠能够产生减少ADE现象的血清型特异性的免疫应答(Hermida L,Rodriguez R,Lazo L,Silva R,Zulueta A,ChineaG,Lopez C,Guzman MG,Guillen G.2004.A dengue-2 Envelopefragment inserted within the structure of the P64kmeningococcal protein carrier enables a functional immuneresponse against the virus in mice.J Virol Methods.2004 Jan;115(1):41-9)。当施用3次剂量并分析产生的抗体时,证实了抗病毒的血清型特异性抗体的更高诱导。同样地,检测到比仅由衣壳诱导的那种更高且比由该融合蛋白诱导的那种显著更高的淋巴组织增生性应答。
平行地,为了了解使用这2种抗原的基因融合物是否能够获得组合效应,构建了包含DEN-2病毒的包膜蛋白的III结构域(其与衣壳蛋白基因的N-末端融合)的质粒。所得到的具有40%纯度的蛋白质在Balb/c小鼠中产生比由单独的衣壳诱导的那种更高的淋巴组织增生性应答,和产生比由PD5诱导的那种更高的血清型特异性抗体应答。
