Description
本发明涉及对生物标志物的测定,其可用于纤维化疾病的诊断和其发展的预后,包括指示慢性损伤后发生纤维化之风险的生物标志物。
特别地,根据本发明,发现如下所述生物标志物是可用的:与I、III、IV、V和VI型胶原、弹性蛋白、C-反应蛋白,以及蛋白聚糖,包括双糖链蛋白聚糖(Biglycan)、饰胶蛋白聚糖(Decorin)、多功能蛋白聚糖(Versican)和基底膜蛋白聚糖(Perlecan)的降解片段有关的生物标志物。
纤维化疾病(包括表1中列出的那些疾病)是发病和死亡的一个主要原因,例如,在全世界范围内,每年有800,000人死于肝硬化1。
表1.不同的纤维化疾病2
“纤维化疾病”是产生纤维化的任何疾病,无论是主要或是次要症状。
纤维化是由多种刺激诱导的慢性炎症反应的最后结果,所述刺激包括持续感染、自身免疫反应、变态反应、化学损伤、辐射和组织损伤。纤维化的特征是细胞外基质(ECM,extracellular matrix)的积聚和再组织。尽管具有明显的病因学和临床差异,大多数慢性纤维化疾病都具有持续性的刺激物,所述刺激物使得下列项持续产生:生长因子、蛋白水解酶、血管生成因子和纤维化细胞因子,其共同刺激结缔组织成分(尤其是胶原和蛋白聚糖)的沉积,所述成分进展性地重塑并破坏正常组织架构3,4。尽管对人类健康影响巨大,但目前尚没有获得批准的直接靶向纤维化机制的治疗5。
纤维化的关键细胞介导物是成肌纤维细胞,其在被激活时作为主要的产胶原细胞。
细胞外基质(ECM,Extracellular Matrix)
纤维发生是一个涉及复杂的细胞和分子机制的动力学过程,其通常来源于组织损伤6。纤维发生是正常ECM调节失衡的结果,所述失衡改变大分子的浓度,导致组织的大小和密度增加,伴有进展性的功能受损。这些大分子主要是具有结构和粘附功能的纤维蛋白,例如胶原和蛋白聚糖。
胶原
胶原在人体内分布广泛,即人体内蛋白质量的~30%是由胶原构成的。胶原负责大多数结缔组织之ECM的结构完整性。ECM含量来自合成和降解之间的精细平衡,所述平衡不仅通过基因表达和蛋白质分泌的调节而受到严格控制,而且还通过内源性蛋白酶抑制以及金属蛋白酶和半胱氨酸蛋白酶对蛋白质的降解而受到严格控制7-9。表2列出了主要的胶原类型及其主要的组织分布。
表2.主要胶原类型及其组织分布。
I型胶原是含量最丰富的胶原,其见于大多数结缔组织中。其对于主要的胶原组分是I和III型胶原的骨和皮肤的结构来说尤其重要10。
I和III型胶原是肝和肺的主要组分,其在健康组织中的比例为1∶1。此外,IV和VI型胶原见于大多数组织的基底膜中。V型胶原的最常见定位是在特征性的胶原原纤维中,与I和III型胶原相关联10。
有些胶原具有有限的组织分布:例如,II型,几乎仅见于软骨中11。
在纤维发生的过程中,胶原的净量增加12-14。表3以示例的方式显示了肝纤维化的过程中胶原的增加。
表3.从正常到硬化的人肝脏的胶原组分的变化15。
弹性蛋白
弹性蛋白存在于很多结缔组织中,主要是那些有弹性的结缔组织。其具有非常高的氨基酸甘氨酸、缬氨酸、丙氨酸和脯氨酸的含量,分子量为64至66kDa。其组织成为由830个氨基酸组成的不规则或随机的卷曲构象。弹性蛋白的形成如下所述:在由赖氨酰氧化酶催化的反应中,很多可溶性弹性蛋白原蛋白分子相连接,产生了巨大的、不可溶的、耐久的交联阵列。
弹性蛋白在动脉中作为压力波传播的介导物而发挥重要功能,以帮助血液流动,并且在大的弹性血管(例如主动脉)中尤其丰富。弹性蛋白在肺、弹性韧带和皮肤中也非常重要。
尽管在研究弹性蛋白的合成和周转中投入了很多的努力,但目前为止尚未将来自蛋白水解切割该基质分子的新表位与纤维化的疾病发生相关联。
波形蛋白
波形蛋白是中间丝蛋白质家族的成员。中间丝是真核细胞的重要结构特征。它们与微管和肌动蛋白微丝一起组成细胞骨架。尽管多数中间丝是稳定的结构,但是在成纤维细胞中,波形蛋白以动态结构的形式存在。该中间丝被用作中胚层来源组织的标志物,并因此被用作肉瘤的免疫组织化学的标志物。
Hertig及合作者(Hertig等,J Am Soc Nephrol.2008 Aug;19(8):1584-91)研究了,在患有慢性同种异体移植物肾病的受试者肾小管上皮细胞中,上皮向间质的转变是否能够预测同种异体移植物中纤维化的进展,并在来自这些的83个活检样品中测量了波形蛋白的表达。他们的确发现了波形蛋白表达升高与手术后1年时肠纤维化评分之间的相关性。
在肝纤维化另一项研究中,Meriden及其同事(Meriden等,ClinGastro & Hepatol 2010;8:289-296)发现波形蛋白表达(在F0期获取的活检样品中)与纤维化发展之间的显著相关性,其水平的升高预测肝纤维化的快速进展。
因此,我们想要研究,循环中波形蛋白片段是否可以充当灵敏且特异性的纤维化生物标志物。
蛋白聚糖
蛋白聚糖是一组多种多样的大分子,其将不同数目的糖胺聚糖(GAG,glycosaminoglycan)侧链与核心蛋白共价连接16。这些GAG是二糖重复(例如N-乙酰葡糖胺或N-乙酰半乳糖胺)的聚合物,由于二糖单元上的羟基、羧基化和硫酸化的侧基,其是酸性的(带负电荷)。这使它们高度亲水,因而协助水和阳离子(例如来自细胞外液的钠)的扩散17。另外,GAG具有以下能力:与例如透明质酸链形成非共价连接,以形成甚至更大的分子复合物16。表4列出了研究最多的与结缔组织相关的蛋白聚糖。
表4.结缔组织之细胞外基质的蛋白聚糖
C-反应蛋白
C-反应蛋白(CRP,C-reactive protein)是应答于不同的临床疾病(例如炎症、感染或外伤)而由肝所产生的急性期血清蛋白29。CRP的产生是由受影响的或损伤的组织释放的细胞因子(例如IL-6)所诱导的。CRP的生理学作用尚不清楚,且对其促炎或抗炎作用的讨论仍在进行中。
蛋白酶
纤维发生过程中,ECM的合成与降解间的失衡是由低密度的内皮下基质转化成为富含间质胶原的基质所导致的。这种胶原和蛋白聚糖的增加可能是如下原因中的一种或两种所引起的:(1)蛋白质产生的减少,和(2)蛋白质降解减少,因此基质降解较少。蛋白质降解的减少最近获得了越来越多的关注。在该过程的调节中,基质金属蛋白酶(MMP,matrixmetalloproteinase)及其组织抑制剂(TIMP)与其他蛋白酶及其抑制剂(例如半胱氨酸蛋白酶和胱抑素)一起发挥重要的作用。
MMP
MMP是一大组内肽酶,其能够降解大多数(如果不是所有)ECM组分。目前,已发现超过25种MMP。MMP的特征在于包含金属原子(一般为锌)的活性位点,其以酶原的形式分泌。不同的MMP在不同的组织中表达。表5中显示肝脏中的MMP。
表5.肝脏中的MMP30-32。
TIMP通过以底物和组织特异性的方式结合MMP以及三分子复合物中的膜-1型金属蛋白酶来阻断MMP的蛋白酶水解活性(表6)。在纤维化过程中,TIMP水平显著增加,而MMP水平中等增加或保持相对稳定(除了MMP-2以外),其总体上使得胶原降解减少。
表6.肝中的TIMP31
成纤维细胞激活蛋白
成纤维细胞激活蛋白α亚基(FAPa或FAP,α)是属于丝氨酸蛋白酶家族的膜整合明胶酶。FAPa是异二聚化膜结合蛋白酶复合物(也被称为170kDa黑素瘤膜明胶酶、整合膜丝氨酸蛋白酶和Seprase)的α亚基,而DPP4(CD26)是β亚基。有些细胞仅产生FAPa同二聚体,有些仅产生DPP4同二聚体。单体是无活性的。FAP,α在上皮癌的反应性间质成纤维细胞、愈合中伤口的肉芽组织以及骨和软组织肉瘤的恶性细胞中选择性表达33。该蛋白被认为参与成纤维细胞生长的控制或者发育、组织修复和上皮癌变过程中上皮-间质的相互作用。已证明,FAP的表达随纤维化的阶段而增加34,35。
纤维化生物标志物
已经提出了许多针对纤维化疾病的生物化学标志物,但不是该疾病的特异性产物。表7中是临床试验中使用的肝脏纤维化的生物化学标志物的例子。此外,有其他纤维化疾病的生物标志物的很多例子12,36-42。
表7 一些已知的肝纤维化标志物的总结。
US5387504描述了通过溶基质蛋白酶(stromelysin)在聚集蛋白聚糖(aggrecan)位点N341-F342的作用所释放的新表位VDIPEN,以及应用所述新表位的特异性单克隆抗体的RIA测定。更一般地说,描述了特异性针对聚集蛋白聚糖片段的单特异性抗体,其由特异性的溶基质蛋白酶切割所产生。在骨关节炎、类风湿性关节炎、粥样硬化病变、痛风、炎性肠病(inflammatory bowel disease,IBD)、特发性肺纤维化(idiopathicpulmonary fibrosis,IPF)、某些癌症、关节损伤和多种炎性疾病中发生溶基质蛋白酶的升高。据报道,在特发性肺纤维化中溶基质蛋白酶升高,据说所述测定可在血液或其他生物流体中进行,以检测聚集蛋白聚糖的溶基质蛋白酶切割产物,对所述片段的定量可用于诊断IPF和其他疾病。然而,对此没有提供证据,并且据我们所知,没有后续的出版物来验证这一预测。此RIA测定已经商业化很多年了,没有出现其成功用于诊断或监测任何纤维化疾病的报道。
美国专利7,225,080公开了在患者中诊断炎症、纤维化或癌症疾病的方法,其通过下述步骤进行:测量选自下列的至少四个生物化学标志物的值:所述患者的血清或血浆中的α2-巨球蛋白、AST(天冬氨酸氨基转移酶,aspartate aminotransferase)、ALT(丙氨酸氨基转移酶,alanineaminotransferase)、GGT(γ谷氨酰转肽酶,gammaglutamyltranspeptidase)、γ-球蛋白、总胆红素、白蛋白、α1球蛋白、α2球蛋白、结合珠蛋白、β-球蛋白、apoA1、IL-10、TGF-β1、apoA2和apoB,以及随后综合所述值,以确定所述患者中肝纤维化和/或坏死性炎症病变的存在。该专利没有教导对携带纤维化疾病过程中产生的新表位的肽片段进行定量测量。
美国专利6,060,255描述了用于诊断肝纤维化程度的方法,所述方法包括以下步骤:在样品中使用特异性结合IV型胶原的抗体测量高分子量形式的IV型胶原浓度,以及将测量结果与肝纤维化的程度相关联。同样,没有利用体内发挥作用的蛋白水解酶所产生的新表位。所述样品事实上是被胃蛋白酶所消化的,其可掩盖样品中胶原切割的天然模式。
美国专利4,628,027(Gay)公开了结缔组织蛋白特异性抗体的生产,更具体来说,公开了通过针对人胶原和参与胶原降解之酶的融合细胞杂合体来生产单克隆抗体。描述了使用针对结缔组织蛋白的单克隆抗体来建立组织学、细胞学和生物学流体样品的胶原特征谱。然而,该专利没有描述基于抗体与所述结缔组织蛋白上新表位的结合来测量结缔组织蛋白。
N等,J BoneMiner Res,199898在患有原发性胆汁性肝硬化(伴有肝纤维化增加的疾病)的患者中评价了骨周转标志物I型胶原N-端肽(NTX,N-telopeptide of type I collagen)、I型胶原C-端肽(CTX,C-telopeptide of type I collagen)和I型胶原的N-末端前-肽(PINP,N-terminal pro-peptide of collagen type I)。与对照相比,在患者中,NTX、CTX和PINP的水平升高,并与所述疾病的组织学阶段相关。在NTX中使用的抗体是针对组织蛋白酶K在I型胶原的N-末端的切割位点而产生的,并依赖于新表位JYDGKGVG↓。在CTX中使用的抗体是针对组织蛋白酶K在I型胶原的C-末端的切割位点而产生的,并依赖于新表位EKAHDGGR↓。这些标志物位于I型胶原的端肽中,且不在I型胶原的内部。PINP测定所使用的单克隆抗体是针对PINP序列中的内部表位而产生的,其不是新表位。
S等,Gut.,199999证明,与对照相比,I型胶原的C-末端交联的端肽(ICTP)在酒精性肝硬化患者中升高。所描述的研究表明生物化学标志物可以反映肝纤维化。已经针对胰蛋白酶和胶原酶切割的I型胶原产生了ICTP的多克隆抗体。然而,所述抗体并不结合新表位。
Rosen HN等,Calcif Tissue Int,2004100在接受激素替代治疗(HRT,hormone replacement treatment)的女性中评价了骨周转标志物I型胶原的N-端肽(NTX)和I型胶原的C-端肽(CTX)。在该研究中,观察到了骨周转标志物随着治疗而降低。NTX中使用的抗体是针对组织蛋白酶K在I型胶原的N-末端中的切割位点而产生的,并依赖于新表位JYDGKGVG↓。CTX中使用的抗体是针对组织蛋白酶K在I型胶原的C-末端中的切割位点而产生的,并依赖于新表位EKAHDGGR↓。与本发明不同,这些抗体被用于评价骨代谢而非评价纤维化。
Lein M等,Eur Urol,2007101在接受唑来膦酸治疗的前列腺癌患者中评价了新表位特异性的骨周转标志物I型胶原的N-端肽(NTX)和I型胶原的C-端肽(CTX)。在该研究中,观察到了骨周转标志物随着治疗而降低。NTX中使用的抗体是针对组织蛋白酶K在I型胶原的N-末端中的切割位点而产生的,并依赖于新表位JYDGKGVG↓。CTX中使用的抗体是针对组织蛋白酶K在I型胶原的C-末端中的切割位点而产生的,并依赖于新表位EKAHDGGR↓。与本发明不同,这些抗体被用于评价骨转移的侵袭过程中的骨代谢,而非纤维化。
PIIINP已在很多研究中用于评价纤维化疾病的严重性102,用于严重烧伤后患有皮肤纤维化的患者中103,用于在非硬化性原发性胆汁性肝硬化中评价疾病的进展104,用于原发性胆汁性肝硬化和慢性丙型病毒性肝炎中105。
在患有心肌纤维化的患者中测量PIIINP和ICTP106。
很多报道将一组生物化学标志物进行联合以改善生物化学指标的预测。在205位患有F0至F4期纤维化的患者中测量了11种不同的血清标志物,提供最多信息的标志物是α2巨球蛋白、α2球蛋白(或触珠蛋白)、γ球蛋白、载脂蛋白A1、γ谷氨酰转肽酶和总胆红素107。获得了这些标志物的指标具有评分在0至0.10范围内(全部患者的12%[41])的阴性预测值(100%确定没有F2、F3或F4),和评分在0.60至1.00范围内(全部患者的34%[115])的高阳性预测值(>90%确定存在F2、F3或F4)。
然而,上述的报道中没有一个如本发明所主张的那样提出,基于与新表位结合的抗体来测量肽片段可用于评价患有纤维化疾病的患者。
本发明现在提供诊断纤维化的方法,其包括:进行免疫测定以测量患者体液样品中天然存在的包含新表位的蛋白质片段,以及将所述患者中所述测量值相对于正常值的升高与纤维化的存在相关联,其中所述免疫测定通过包括如下步骤的方法进行:将所述样品中天然存在的蛋白质片段与免疫结合伴侣(immunological binding partner)相接触,所述免疫结合伴侣与蛋白酶切割蛋白质所形成的新表位反应,以及测量肽片段与所述免疫结合伴侣的结合程度从而测量其中的包含所述新表位的蛋白质片段,并且其中所述蛋白质是I型胶原、III型胶原、IV型胶原、V型胶原或VI型胶原、双糖链蛋白聚糖、饰胶蛋白聚糖、光亮蛋白聚糖、多功能蛋白聚糖、基底膜蛋白聚糖、神经蛋白聚糖(neurocan)、短小蛋白聚糖(brevican)、纤调蛋白聚糖(fibromodulin)、丝甘蛋白聚糖(serglycin)、黏结蛋白聚糖(syndecan)、β蛋白聚糖(betaglycan)、CRP或波形蛋白,前提是当切割I型胶原形成新表位时,该切割不在组织蛋白酶K切割I型胶原的位点处。公开于2009年5月14日(在本申请优先权日之后)的WO2009/059972公开了针对III型胶原新表位的测定,但没有公开此测量水平的升高与纤维化的存在或程度相关联。任选地,根据本发明的测定是基于上文所述蛋白质中除III型胶原之外的一种,或者如果基于III型胶原,则应用针对在下述切割位点形成的新表位之一的免疫结合伴侣:PGIPGRNGDP*SEQ ID NO1、*ESCPTGPQNY SEQ ID NO2或PKGDTGPRGP*SEQ ID NO3(其中,*指示切割位点)。
为了这些目的,心血管疾病可能不被认为是纤维化,或根据本发明检测的纤维化可以是除伴有心血管疾病的纤维化之外的纤维化。任选地,根据本发明的免疫测定中升高的结果与皮肤纤维化、肺纤维化或肝纤维化相关联。
该方法可包括获得患者生物流体样品的预备步骤。
本发明包括免疫测定方法,其测量在体液样品中天然存在的包含新表位的蛋白质片段,其中所述免疫测定通过包括如下步骤的方法进行:
将所述样品中天然存在的蛋白质片段与免疫结合伴侣相接触,所述免疫结合伴侣与蛋白酶切割蛋白质所形成的新表位反应,以及测量肽片段与所述免疫结合伴侣的结合程度从而测量其中的包含所述新表位的蛋白质片段,并且其中所述蛋白质是神经蛋白聚糖、短小蛋白聚糖、纤调蛋白聚糖、丝甘蛋白聚糖、黏结蛋白聚糖、β蛋白聚糖、I型胶原、IV型胶原、V型胶原、VI型胶原、CRP或波形蛋白,前提是当切割I型胶原形成新表位时,该切割不在组织蛋白酶K切割I型胶原的位点处。任选地,根据本发明的测定是基于上文所述蛋白质中除III型胶原之外的一种,或者如果基于III型胶原,则应用针对在下述切割位点处形成的新表位之一的免疫结合伴侣:PGIPGRNGDP*SEQ ID NO1、*ESCPTGPQNY SEQ IDNO2或PKGDTGPRGP*SEQ ID NO3(其中*指示切割位点)。
所述免疫结合伴侣可具有对肽片段的特异性结合亲和力,所述肽片段包含C-末端新表位或N-末端新表位。
与新表位的特异反应性或对新表位的免疫亲和力暗示相关的免疫结合伴侣不与所述新表位所来源的完整蛋白质反应。优选地,如果所述序列延长越过各自的切割位点,则所述免疫结合伴侣不与新表位序列(例如下文列出的序列)反应。
本文中使用的术语“免疫结合伴侣”包括多克隆和单克隆抗体以及抗体的特异性结合片段,例如Fab或F(ab’)2。因此,所述免疫结合伴侣可为单克隆抗体或具有特异性结合亲和力的单克隆抗体片段。
优选地,所述肽片段是I、III、IV、V或VI型胶原、弹性蛋白、C-反应蛋白或者是下列蛋白聚糖之一的片段:双糖链蛋白聚糖、饰胶蛋白聚糖、多功能蛋白聚糖和基底膜蛋白聚糖。结缔组织蛋白是优选的。优选地,免疫结合伴侣所结合的新表位序列不存在于任何其他蛋白中,或者不存在于本发明方法相关的任何其他蛋白质中。
多个候选蛋白酶可负责消化纤维化组织中的蛋白质。很可能地,这是大范围的复杂过程的结果,其导致依赖于疾病水平的不同新表位特征谱。

实施例1:用MMP-9降解的III型胶原
方法
切割:将从人胎盘中分离的III型胶原溶于10mM醋酸(1mg/ml)中。随后让该蛋白溶液通过滤器(Microcon Ultracel YM-10)以除去片段杂质。在37℃下,用4-氨基苯汞乙酸盐(APMA,Sigma)预活化MMP-93小时。活化后,以100∶1混合III型胶原和MMP-9,并在37℃下振摇孵育3天。
用液相色谱/质谱(LC/MS,liquid chromatography/massspectrometry)分析该溶液,通过进行Mascot检索来鉴定片段。通过同源性检索选择肽序列,确保与其他的或相关的蛋白没有交叉反应性,并且没有物种间的交叉反应性。
抗体设计:合成肽序列并将其与卵清蛋白(OVA,ovalbumin)相缀合。每2-3周免疫小鼠,共免疫5次。用筛选肽(选择(selection)和去选择(de-selection))检查抗体效价。当达到足够的抗体效价时,选择阳性小鼠用于融合,实施安乐死,分离脾脏,取出B-细胞用于与骨髓瘤细胞融合。通过培养并再接种单细胞克隆中存活的嵌合细胞来选择抗体生成细胞。通过选择和去选择肽选择克隆,然后进行天然反应性检测(图1),这是由于新表位是由合成的小肽序列产生的,其可能不反映天然蛋白的性质。选择IgG亚型克隆用于抗体的生产。通过蛋白-G柱完成抗体的纯化。
测定的开发:在竞争性ELISA中,通过棋盘式分析,通过对包被抗体和筛选肽的稀释来确定最优抗体浓度。表24中显示以MMP-9降解胶原(CO3)检测的不同测定。
检出限 | 0.5ng/ml |
平均测定间变异 | 3.71% |

实施例2:生物相关样品的CO3:
与假手术大鼠相比,胆管结扎大鼠的CO3水平。
方法:在Nordic Bioscience的动物研究设施中安置40只雌性Sprague-Dawley大鼠(6月龄)。该实验经丹麦司法部实验动物委员会批准,并按照欧洲标准的临床试验规范(2008/561-1450)进行。在18-22℃下,将所述大鼠安置在标准的III-H笼中,有寝具和巢材(Altromin 1324;Altromin,Lage,Germany)并自由摄取纯水(Milli-Q system;Millipore,Glostrup,Denmark)。将大鼠安置于12小时明/暗周期的环境中。
用常规BDL诱导肝纤维化。简而言之:麻醉大鼠,找到胆管,在胆管附近进行两处结扎,然后在两处结扎之间切开,关腹。在假手术大鼠中,不结扎胆管就关腹。
将大鼠分成2组:第1组在2周后被处死(10只BDL和10只假手术大鼠),而第2组(9只BDL和10只假手术大鼠)在4周后被处死。研究阶段完成之后(2或4周),至少14小时禁食后,用CO2窒息和放血处死所有存活的动物。
在轻度CO2/O2麻醉下,在基线时和在终止时从至少禁食14小时大鼠的后眶窦取血样。收集所述血液并在室温下放置30分钟使其凝集,然后1500g离心10分钟。将所有无凝块的液体转移到洁净的管中并在-80℃下储存。在5倍稀释的来自大鼠的血清样品中测量CO3。假定正态分布,以Mann-Whitneys双尾非参检验(α=0.05)比较假手术组和BDL的水平间的统计学显著性。
与假手术的动物相比,CO3水平在BDL组中显著增加。图2a和b中显示该结果。
实施例3:
不同纤维化疾病中的CO3(人血清)
在患有三种不同纤维化疾病的人血清中测量CO3的水平:慢性阻塞性肺病(COPD,Chronic obstructed pulmonary disease)、硬皮病和丙型肝炎(HCV,Hepatitis virus C)。所述血清样品取自Sera LaboratoriesInternational Ltd(SLI Ltd),UK。在三个不同的纤维化疾病中,CO3水平升高(图3)。
实施例4:
抗体开发-标志物CO3-610C的检测
用活化的MMP-9(Merck KGaA,Darmstadt,Germany)体外降解III型胶原(Abcam,Cambridge,UK)2天。用LS-MS/MS对降解片段进行测序,并通过MASCOT检索进行鉴定。选择特异性的肽序列610KNGETGPQ用于抗体生产。该序列的N-末端是人III型胶原的610位残基。在用大约200μL乳化的抗原和50μg CO3-610C(KNGETGPQGPGGC-OVA)皮下免疫4-6周龄的Balb/C小鼠之前,将合成肽缀合到卵清蛋白上。在弗氏不完全佐剂(Freund’s incompleteadjuvant)中,以两周的间隔进行连续免疫,直到达到稳定的血清效价水平。从第二次免疫开始,对小鼠放血。每次放血时,测量血清效价,并选择有最高抗血清效价的小鼠用于融合。第四次免疫之后,让该小鼠休息一个月,并随后在分离脾细胞用于细胞融合之前的三天,用100μL 0.9%氯化钠溶液中的50μg CO3-610C进行静脉加强。
使用如下肽选择产生单克隆抗体的克隆,a)免疫原性肽:KNGETGPQGP-GGC-卵清蛋白(OVA)(807678),b)筛选肽KNGETGPQGP-PG-K-生物素(807971),和c)代表II型胶原α1链的去选择肽KDGETGAAGPPGK-生物素(118318)、代表I型胶原α1链降解产物的KDGEAGAQGPPGK-生物素,购自Chinese Peptide Company,北京,中国。ELISA包被板获自NUNC(Thermofisher,Copenhagen,Denmark)。肽缀合试剂和缓冲液由Pierce(Thermofisher,Copenhagen,Denmark)生产。
用于溶解包被肽的缓冲液由如下组分构成:40mM Na2HPO4,12H2O、7mM KH2PO4、137mM NaCl、2.7mM KCl、25mM EDTA、0.1%吐温20、1%BSA、10%山梨醇,pH 7。对于血清测定,使用含有如下化学品的缓冲液:8mM Na2HPO4,12H2O、1.5mM KH2PO4、13.7mMNaCl、2.7mM KCl、0.1%吐温20、1%BSA、0.003%酚红,pH 7,4。用于尿测定时,使用不同的缓冲液,包含400mM TRIZMA、0.05%吐温20、0.1%BSA、0.36% Bronidox L5,pH 8,0。对于血清和尿测定,我们使用由如下成分构成的清洗缓冲液:25mM TRIZMA、50mM NaCl、0.036%Bronidox L5、0.1%Tween 20,而反应终止缓冲液是由0.1%H2SO4构成的。用于测定开发的ELISA板来自Roche(Hvidovre,Denmark)货号:11940279,是链霉亲和素包被的。用来自MolecularDevices,SpectraMax M,(CA.USA)的ELISA检测仪分析所有ELISA板。
在预实验中,我们通过进行多个棋盘式分析优化了试剂、其浓度和孵育时间。在20℃,300rpm的持续振摇下,将用链霉亲和素包被的96孔ELISA板进一步地用溶于PBS-TBE缓冲液中的5ng/ml合成肽KNGETGPQGP-生物素化包被30分钟。用清洗缓冲液清洗后,加入20μl样品,继之加入100μl缀合了过氧化物酶的抗人mAb-NB51-32 CO3-610C溶液(在孵育缓冲液中为23pg/ml)。在20℃下孵育该板1小时,期间以300rpm振摇。继之清洗,最后提供100μl四甲基联苯胺(TMB,tetramethylbenzinidine)(Kem-En-Tec货号438OH),并在黑暗中和在300rpm振摇下孵育该板15分钟。为了终止该反应,加入100μl终止溶液,并用450nm波长在ELISA检测仪分析该板,以650nm为参比波长。
通过连续稀释下列物质来绘制标准曲线,对于血清测定来说,稀释生物素化-NB51-32 CO3-610C,对于尿测定来说,稀释生物素化-NB51-134CO3-610C。标准浓度为0、0.33、1、3、9、27、81和162ng/ml。
我们将由此获得的使用免疫测定法检测的片段定名为CO3-610C,因为其序列KNGETGPQGP的N-末端氨基酸K是人III型胶原序列的610位氨基酸。

结果
肝脏外观:处死时,对照动物的肝脏表现出正常的大体形态,而BDL动物的肝脏体积增大。与假手术对照组相比,BDL大鼠的肝重显著增加(处死时的平均重量:手术后2周,假手术组8.1g;BDL组14.1g;手术后4周,假手术组9.0g;BDL组19.4g)(图4A)。用0-3级对肝切片进行半定量评分,与2周相比,4周时肝显示出显著更多的结构改变(图4B)。图4,A图显示胆管结扎(BDL,bile duct ligation)或假手术大鼠的肝重。数据以平均值+SEM表示。***,P<0.0001。B图显示各组肝结构改变的评分。数据以平均值+SEM表示。**,P=0.0094。C图显示天狼星红显微照片,显示假手术大鼠和手术后2和4周的BDL大鼠中的肝结构。与假手术大鼠相比,在BDL大鼠中,肝门束周围的肝结构明显被破坏。胶原以红色突出显示。原始放大倍数是×40。
在组织学检查中,假手术动物的肝未显示出纤维化的症状,显微镜下是正常的(图4C)。在BDL肝中,观察到了显著的导管增殖。在手术后2周组,所述增殖位于肝门束附近,而在4周组,所述增殖已蔓延(图4C)。在胆管结构附近发现胶原沉积。炎症极小并局限于肝门束。未见胆汁郁积的迹象,无论是细胞内胆汁郁积、胆栓、胆汁性梗死或肝细胞玫瑰花结形成。
CO3-610C水平的改变:图5在A图中显示胆管结扎(BDL)或假手术大鼠中MMP-9介导的CO3降解血清水平。数据以平均值+平均值的标准误表示。手术后2周组***P<0.0001和手术后4周组**P=0.0014。B图中显示CO3-610C的Δ值(终止-基线,成对的)手术后2周P<0.0001和手术后4周P=0.0016。C图中显示BDL或假手术大鼠中CTX-II的水平。数据以平均值+平均值的标准误表示。
在BDL组中,与假手术组相比,CO3-610C水平显著增加(平均值:手术后2周,假手术组39.7ng/ml,BDL组100.3ng/ml;组间平均增加153%;手术后4周,假手术组39.7,BDL组92.6ng/ml,组间平均增加133%)(图5A和B)。假手术组中没有改变。在假手术或BDL组中,表征II型胶原降解的CTX-II水平没有改变(图5C)。
III型胶原基因表达:图6显示BDL或假手术大鼠中III型胶原的基因表达。数据以平均值+平均值的标准误表示;手术后2周P<0.0001和手术后4周P=0.0006。
与假手术大鼠相比,在两个BDL组中,III型胶原a1链mRNA显著增加。
蛋白质印迹(Western Blot)和密度测定:图7显示BDL和假手术组大鼠的肝中CO3-610C表达的变化,以如下方式进行评价:A)手术后2和4周的蛋白质印迹法,和B)以密度测定法对蛋白质印迹条带进行定量。
蛋白质印迹分析显示假手术大鼠中非常低水平的CO3-610C(图7A)。手术后2周时或之后,CO3-610C水平显著增加(图7A)。以密度检测分析法对结果进行定量(图7B)。
组织学图像分析:图8A在上面一行显示来自BDL或假手术大鼠的以天狼星红染色的组织学切片。下面一行显示用于在肝中定量总胶原含量(红色)的掩蔽的组织学切片。B图显示以Visiopharm软件定量的总胶原—手术后两周P=0.0081;手术后4周P=0.0047。
以天狼星红染色和使用Visiopharm软件增强的组织学切片显示在BDL-手术大鼠中随时间增加的胶原含量。(图8A)。使用相同的软件对掩蔽中的代表胶原的红色进行定量(图8B),并确证了与假手术大鼠相比,在BDL手术的大鼠中,总胶原含量显著增加(手术后2周P=0.0081;手术后4周P=0.0047)。
相关性:图9A显示,发现Col3a1与CO3-610C的相关性,R2=0.6993,P<0.0001。B图中,发现CO3-610C与胶原%的相关性,R2=0.2278和P=0.0050。C图中,发现Col3a1与胶原%的相关性,R2=0.5409,P<0.0001。
发现如下的相关性:Col3a1mRNA与CO3-610C的相关性,R2=0.6993和P<0.0001(图9A),和CO3-610C与以visiopharm定量的胶原%的相关性,R2=0.2278和P=0.0050(图9B),以及Col3a1mRNA与以visiopharm定量的胶原%的相关性,R2=0.5409和P<0.0001(图9C)。
ECM重塑是组织发育、维持和病变中的综合过程。在细胞迁移、清除损坏的组织和隔离新蛋白的过程中,蛋白水解活性非常重要,以使组织的定位和品质正确和最佳(108:109)。特异性的基质降解产物--新表位--对于鉴定新的肝纤维化基质周转的生物化学标志物和理解纤维化的发病机理来说十分重要。当前没有可用的允许在纤维化发病过程中评价ECM重塑的测量技术和生物化学标志物。
在本实施例中,为了在体内条件下研究CO3-610C标志物,选择6月龄的BDL大鼠,以前已经证明,与较年轻的大鼠相比,其具有较低的胶原重塑。所述大鼠骨骼成熟,生长板近乎休眠,因此,对整体胶原周转的贡献程度较低。其影响生物标志物的灵敏度和特异性。如通过定量组织学分析和伴有重量增加的扩张所评价地,这些大鼠清楚地表现出肝纤维化,因此,所述模型是寻找ECM重塑迹象的适宜模型,尤其是在血清中寻找III型胶原的迹象。
本数据清楚地证明,来自MMP-9介导的III型胶原降解的新表位CO3-610C是用于肝纤维化的诊断性生物化学标志物,从假手术至BDL手术的大鼠,血清中平均增加高达153%。
为进一步研究CO3-610C标志物增加的生物学原理,我们从健康的和患病的肝中提取蛋白质。通过蛋白质印迹,我们鉴定到显著的条带,表明其在疾病的而非健康的肝中是丰富的蛋白片段。这为这个新标志物的病理精确性提供了证据。
为了进一步地研究肝病理周转的表现,我们测量了III型胶原的mRNA。我们发现,与进行假手术的大鼠相比,在BDL大鼠中mRNA增加,这与以前的调查结果相关。这些数据强烈提示,肝纤维化不仅是ECM蛋白的积聚,也是加速的周转状况,其中组织形成和组织降解都高度上调。组织形成超过组织降解,导致疤痕组织随时间积聚。以前的研究已使用其他基质周转蛋白来评价肝纤维化,其中之一是III型胶原形成的标志物N-末端III型前胶原。该标志物代表III型胶原的形成,并在以前的研究中已被证明在肝纤维化中增加。
为了进一步理解所述生物化学标志物CO3-610C的动力学,我们进行了一系列的相关性分析。最重要的是,CO3-610C与以定量组织学在肝中测量的纤维化程度之间具有显著的相关性。肝纤维化的水平与III型胶原的mRNA的表达水平相关。最后,在肝中,CO3-610C与III型胶原的mRNA相关。综上所述,肝中的病理过程与系统的生活标志物CO3-610C的水平之间具有显著的相关性。此外,组织提取物提供的证据表明,循环水平是由局部产生的。
实施例6:人血清样品的ELISA
人血清样品获自患有慢性阻塞性肺病(COPD)(n=5)、硬皮病(n=5)、慢性丙型肝炎病毒感染(n=5)的患者和健康对照(n=5)。以CO3-610ELISA(见上述实施例4)在血清样品中进行检测,以确定CO3-610片段的浓度。在图10中显示结果。健康受试者的血清样品中CO3-610片段的浓度低于30ng/ml,而在患病的受试者中发现循环中的水平升高,提示在受影响的纤维化组织中大量的组织重塑。
实施例7:克隆nb94的反应性
用与卵清蛋白相缀合的合成肽KAFVFP(SEQ ID NO1167)(KAFVFPKESD-GGC-OVA(SEQ ID NO1049))免疫小鼠,使用脾细胞进行融合,并检测单克隆抗体与生物素化KAFVFP(SEQ ID NO 1167)的反应性,即KAFVFPKESD-生物素(SEQ ID NO1049),其固定于用链霉亲和素预包被的微量滴定板的孔中。选择与生物素化KAFVFPKESD(SEQ ID NO1049)结合的抗体,用以进一步的鉴定,所述结合可被KAFVFPKESD(SEQ ID NO1049)共孵育所抑制,而不被延长的肽RKAFVFPKESD(EQ ID NO1166)的共孵育所抑制。优选的单克隆抗体被定名为NB94-37-1A7。
使用竞争性ELISA,基本上如上所述,其使用固定在链霉亲和素包被的微量滴定板孔中的生物素化KAFVFPKESD(SEQ ID NO1049)(以0.15ng/ml使用),使用样品和单克隆抗体NB94-37-1A7进行孵育的步骤(20℃,90分钟)之后,然后是清洗步骤,随后加入过氧化物酶缀合的抗小鼠免疫球蛋白。在2倍稀释液中使用如下物质用于竞争;(1)合成的KAFVFP(SEQ ID NO1167)肽;(2)与CRP无关的无意义肽(KNEGTG);(3)合并的人血清样品;(4)CRP,其用MMP3蛋白水解切割7天,随后通过加入EDTA终止以阻断蛋白酶活性,并在检测前于-80℃下储存;(5)与(4)相同,但是用MMP8替代MMP3;(6)与(4)相同,但是使用组织蛋白酶K(2天)替代MMP3(并以E64为阻断组织蛋白酶K活性的抑制剂)。
该数据证明,单克隆抗体NB94-37-1A7强烈结合合成肽KAFVFPKESD(SEQ ID NO1049),并用MMP3和MMP8切割CPR。用组织蛋白酶K切割CRP释放较少的单克隆抗体NB94-37-1A7所识别的分析物。最后,该数据显示所述抗体在人血清中结合肽片段,证明了该序列在循环肽片段中的存在。
实施例8:生物相关样品中的CO3:四氯化碳(CCl
4
)诱导的大鼠肝硬化
中CO3的水平。
动物和肝硬化的诱导:
本研究包括52只患有纤维化或肝硬化的雄性Wistar大鼠和35只对照雄性Wistar大鼠。为使其发生纤维化或肝硬化,在使用四氯化碳(CCl4)和苯巴比妥的诱导方案中包括三月龄动物。每周两次吸入施用CCl4,并在饮水中添加苯巴比妥(0.3g/l)。整个研究过程中,允许动物自由摄取水和摄食。
纤维化的定量:
用饱和苦味酸(Sigma-Aldrich)中的天狼星红F3B(Sigma-Aldrich,St.Louis,MO)对肝切片(4μm)进行染色。通过分析每只动物的天狼星红染色的肝切片的36个视野来评价相对纤维化区域(以总肝面积的百分比表示)。在10倍放大[E600显微镜(Nikon)和RT-Slider SPOT数码相机(Diagnostic Instruments,Inc.,Sterling Heights,MI)]下获取每个视野。用计算机化的Bioquant Life Science形态测量系统分析结果。为评价相对纤维化面积,用所测得的胶原面积除以净视野面积,然后乘以100。从总视野面积中减去血管管腔面积得到最终的净纤维化面积的计算结果。从被分析的每只动物中测量出以百分比表示的纤维化的量,并以平均值表示。
根据其纤维化/肝硬化阶段的分组
按照天狼星红阳性的肝面积(A组:<5%,B组:5至10%,C组:10至15%和D组:>15%)所确定的百分比,动物被分为4个不同的纤维化和肝硬化阶段(A组:中度纤维化,B组:高度纤维化,C组:中度肝硬化,和D组:高度肝硬化)。为此,在CCl4处理的过程中考虑四个不同的时间点来研究对照和纤维化/肝硬化大鼠:肝硬化诱导计划开始后8、12、16和20周。
透明质酸的测量:
使用夹心法ELISA试剂盒(R&D Systems Inc.,Minneapolis,MN,USA)测量血清透明质酸。
统计学
在适当的时候,用成对Student t检验对结果进行统计学分析。以平均值±S.E.M.表示数据,当p水平为0.05或以下时,其被认为是显著的。
研究设计:
本研究方案中包括的动物被随机分配到如下各组中的一个:A/8周的CCl4处理,B/12周的CCl4处理,C/16周的CCl4处理和D/20周的CCl4处理。在相同的时间点平行研究四个对照组。每组中包括13只纤维化大鼠和7只对照大鼠。该研究结束后,在继续进行24小时的尿收集之前,将大鼠置于标准的代谢笼(Tecniplast Deutschland,Hohenpeissenberg,Germany)中适应3天。重量法测定尿量。在适应期中,允许大鼠自由摄取自来水和食物。随后,将24小时的尿样在2,500rpm下离心5分钟,并分装进入10个聚丙烯管中(每管400μL)。-80℃下存储尿样以用于后续分析。
在预定的尸检中,称重大鼠,用戊巴比妥(50mg/kl)麻醉并断头。收集血液并在室温下放置20分钟使其凝固,并随后以2500rpm离心10分钟。在聚丙烯分装管中收集血清(每管400μL)并通过干冰转移到-80℃冰箱。不考虑在CCl4处理开始时收集的基线血样,以避免可能增加感染风险和/或在实验模型中引入改动的额外干扰,所述实验模型可包括诱导的病理生理性过程的发展。对于组织学和天狼星红染色,将肝左叶的一半置于10%中性缓冲福尔马林中16小时,包埋入石蜡并切成4μm厚的薄片。肝纤维化定量之后,保存尚未使用的石蜡块以用于生物标记物的定量。左肝叶的另一半在液氮中闪冻(flash-frozen),并储存以用于蛋白质印迹、RT-PCR或免疫组织化学分析。按照材料和方法部分对肝纤维化面积、血清和尿渗透压、Na+和K+、白蛋白、肌酐、丙氨酸氨基转移酶和乳糖脱氢酶进行测量。
结果
模型的组织学验证:
用肝切片的天狼星红染色在所有研究的动物中对肝胶原进行定量。在36个连续的显微镜视野中观察,每只动物的最终数据采用红染的平均值(图12)。
图12显示来自两组36幅图片的代表性图片,其用于在以四氯化碳分别处理8和12周的大鼠#1(左)和大鼠#43(右)定量肝中胶原积累。
与对照大鼠相比,在纤维化和肝硬化的大鼠中,血清CO3标志物显示出统计学上显著的增加。根据完全自动化的用于定量纤维化的肝的天狼星红染色操作,对动物进行分类(图13和14)。
图13显示在医院门诊(Barcelona)中进行的吸入CCl4的大鼠和对照大鼠中血清CO3的水平。每个点代表一只动物。根据对用于定量纤维化的肝天狼星红染色进行的计算机化的图像分析方法对大鼠进行分类。
当在每个个体动物中对血清CO3和肝的天狼星红染色的定量值进行研究时,我们发现这两个变量之间存在统计学上显著的相关性(R2=0.4087;n=21)(图14)。
我们已经将CO3-610C的水平与肝纤维化的透明质酸(HA,hyaluronic acid)血清学基准进行了比较。用商品化的ELISA试剂盒定量HA水平,结果显示,在肝硬化大鼠与纤维化动物中ECM组分显著升高(图15和16)。
CO3与天狼星红的相关性超过与HA的相关性。可通过CO3的血清学测量来解释肝纤维化组织学定量中超过70%的变异。剩余30%归因于未知变量或固有的变异性。相对地,通过测量透明质酸仅可解释肝纤维化的25%(图15)。
如根据以前的结果所预期的,在CO3和透明质酸之间可能不存在相关性,提示它们在肝纤维化发生的过程中是两个独立的病理生理过程(图17)。
实施例9:博来霉素在小鼠中诱导的皮肤纤维化。
通过在皮肤上应用PBS或博来霉素来处理小鼠。在小鼠中,尿中MMP-9介导的III型胶原(CO3)降解片段CO3-610水平的增加与皮肤纤维化的进展相关。
图18显示PBS处理的小鼠在处理的第8周时的皮肤切片(A图)和博来霉素处理的小鼠在处理的第8周时的皮肤切片(B图)。C和D图中绘制了用PBS(n=7/时间点)和博来霉素(n=13/时间点)处理2周(P=0.0029)、4周(P=0.0004)、6周(P<0.0001)和8周(P<0.0001)的小鼠之间皮肤厚度的增加。本研究期间,PBS(n=28)和博来霉素(n=52)处理的小鼠之间的总体皮肤厚度增加(P<0.0001)。通过Visiopharm软件计算皮肤厚度以作为每个皮肤切片的总体数目而非取样图片的。
图19显示CO3-610的尿测定结果,其证明本研究的全部时间点中显著增加。该图显示每个时间点的结果(n=7PBS、n=13博来霉素处理的每个终止点)和用于全部时间点的总体CO3-610水平(n=28PBS和n=52博来霉素处理的小鼠)。2周P=0.0008,4周P<0.0001、6周P<0.0001、8周P<0.0001和总体P<0.0001。
图20显示了对照C和博来霉素B处理2和8周后CO3-610的蛋白质印迹图像(A图)。B图中显示所有时间点CO3-610的密度测量(n=7PBS和n=13博来霉素处理的每个终止点)和总体CO3-610水平(n=28PBS和n=52博来霉素处理的小鼠),证明CO3-610水平统计学上显著的增加(P<0.0001)。
如图21所示,在尿测定中,发现CO3-610水平与皮肤厚度的进展相关联,因此,总胶原沉积r=0.4883,R2=0.2384。
如图22所示,在CO3-610ELISA尿测定和蛋白质印迹密度测量的结果之间发现统计学上显著的相关性(r=0.6528,P<0.0001)。
