Description

抗原PLA2R-THSD7A-NELL-1融合蛋白及其产品和用途
技术领域
本发明涉及生物技术领域，特别是涉及一种抗原PLA2R-THSD7A-NELL-1融合蛋白及其 产品和用途。
背景技术
膜性肾病(membranous nephropathy，MN)是一种自身免疫性肾小球疾病，特点是形成 原位免疫复合物，沉积在肾小球足细胞上皮下对肾小球结构进行破坏。有研究表明，磷脂酶 A2受体(phospholipase A2 receptor，PLA2R)和I型血小板反应蛋白7A(THSD7A)能作为靶 抗原在肾脏小球内沉积并与肾脏循环中的抗PLA2R抗体形成新生免疫抗原-抗体复合物，即 导致了特发性膜性肾病(70～75％)的发生。膜性肾病按病因又可分为特发性膜性肾病 (idiopathic membranous nephropathy，IMN)和继发性膜性肾病(secondarymembranous nephropathy，SMN)，但75～80％的患者被诊断为IMN。
PLA2R是一种存在于正常人足细胞中的跨膜糖蛋白。PLA2R有N型和M型两种，但人肾 脏组织中主要表达的是M型PLA2R，且已确定M型PLA2R是自身抗体的主要靶抗原。M型PLA2R编码区长4392bp，编码1464个氨基酸，编码蛋白的相对分子质量为180kDa。PLA2R 属于甘露醇受体及C型外源性凝集素超家族的一员，主要由短胞内端(C端)、长胞外端和 一个跨膜域组成。胞外结构包含10个结构域，其中包括半胱氨酸富含域(cysteine-richdomain， CysR)、8个C型凝集素样结构域(C-type lectin-like domains，CTLDs)和纤维链接蛋白样Ⅱ 型结构域(fibronectin type II domain，FNII)。另外，Dong等以HEK293F制备重组蛋白rPLA2R， 冷冻电镜观察结果显示，M型PLA2R可以分为三组：CTLD1～CTLD2、CTLD4～CTLD5和 CTLD7～CTLD8，且蛋白在酸性条件下，结构稳定，蛋白柔性较高。PLA2R可以在足细胞膜 表面持续表达，Maryline等发现，3个靠近PLA2R N末端的结构域，均可作为抗PLA2R抗体识 别的优势表位。虽然去糖基化后仍保持免疫原性，但以还原剂处理后，抗体针对PIA2R的反 应性消失。有研究表明，PLA2R主要位于人类2号染色体q23-q24区，最先存在于脑组织，后 发现在不同动物的肺、肝、肾等多种脏器中也有表达，且2号染色体上的PLA2R基因编码的遗 传变异与膜性肾病相关。但是，单独检测血清PLA2R抗体对IMN诊断的精确度不能满足要求。
THSD7A蛋白是2014年在原发性MN患者中发现的靶细胞抗原，其是一种已知的位于细 胞外的I型跨膜蛋白，这个250kDa的糖蛋白已经被发现含有多个包含抗原表位的区域，这些 区域是免疫系统的目标。THSD7A主要表达于PLA2R阴性的患者体内。有研究显示表达THSD7A的肾小球上皮细胞发生了明显的细胞骨架重排列，细胞形态发生改变，并在抗体与细胞膜结合时发生局部粘连。Nicola M通过实验证明人和兔抗THSD7A通过改变抗体直接致病 在足突细胞结构中，应力纤维的形成增加局部粘连信号的激活。这些都表明，抗THSD7A抗 体可能直接破坏足突细胞的完整性，导致细胞损伤和蛋白尿。在现有研究中，基本上在2.0～13.6％ 的IMN患者中存在THSD7A。一项研究中，12例患者(2％)出现THSD7A相关特发性膜性肾 病，占PLA2R阴性患者的16％(64例中的10例)。
Larissa Seifert等通过对来自THSD7A相关IMN患者的31份血清样本进行了Western和 Native Blotting检测，确定了THSD7A的细胞外拓扑结构为21个血栓蛋白I型结构域串联，其中， 28份(90％)血清样本识别多个抗原决定基域，由第一和第二N末端结构域组成的复合物被31 例患者血清样本中的27例(87％)识别。
临床上用于膜性肾病检测的方法主要为酶联免疫吸附测定(ELISA)，该商业化试剂盒所 用的靶抗原多为PLA2R的胞外域的重组蛋白。单纯用PLA2R为靶抗原进行膜性肾病检测会出 现一定的漏检。
Nel样分子I型(neural epidermal growth factor-like 1 protein，NELL-1)是一种外分泌型 糖蛋白，可在人类胚胎肾细胞中表达，充当细胞外基质成分。2020年，SETHI等在《Kidney International》上发表最新研究发现，NELL-1在经肾脏活检明确的PLA2R和THSD7A阴性 MN患者血清和肾小球中过表达。IF共聚焦显微镜显示NELL-1和IgG共定位于肾小球基底 膜。同时检测到NELL-1循环抗体的存在，表明NELL-1可能是IgG的靶抗原，并由此推测 NELL-1和抗NELL-1与MN密切相关。
而将PLA2R、THSD7A以及NELL-1的基因序列提取出来并通过线性相连拼接后的融合蛋 白容易造成空间位阻，特异位点被阻挡，特异性又变差。
因此，针对现有技术不足，提供一种抗原PLA2R-THSD7A-NELL-1融合蛋白及其产品和 应用以克服现有技术不足甚为必要。

S2：重组质粒转染HEK293T细胞。
将HEK293T细胞接种于6孔板，转染当天，检测细胞数及活力，细胞活力必须在95％以上。以30mL细胞转染体系计算，细胞数调整为2.5×106～3×106个/mL，总细胞数约为 7.5×107个，总细胞培养体积调整为25.5mL。将30μL质粒用1.5mL Opti-MEMI无血清培 养基稀释，并混匀，室温放置5min；将80μL转染试剂ExpiF ectamineTM 293用1.5mL Opti-MEMI无血清培养基稀释，并混匀，室温放置5min；将后面的液体加入前面的液体中， 期间不断摇晃，最后振荡混匀，室温放置20min；最后将3mL转染混合液加入到待转染的 细胞中。转染6h后，弃去原液，加含浓度为100mL/L胎牛血清的DMEM培养基。
S3：抗原的诱导表达和纯化和应用。
转染后16～18h，向转染细胞中加入150μL ExpiF ectamineTM 293TransfectionEnhancer 1 以及1.5mL ExpiF ectamineTM 293Transfection Enhancer 2。培养4～5d(具体培养时间按照细 胞数及活力进行调整)后收集细胞及上清。超声波裂解细胞，提取总蛋白。
使用ANTI-FLAG M2 Affinity Gel(Sigma)完成FLAG标签融合蛋白的分离纯化的整个 操作过程须在2～8℃下进行以避免抗FLAG单抗M2失活：ANTI-FLAG M2 affinity gel置于 冰上融化，混合均匀后吸取10μL于1.5mL干净离心管，在4℃下，8000×g离心30秒，用微量进样器小心吸去上清；向离心管加入1mL TBS(pH 7.4)，重悬混匀亲和凝胶，4℃下，8000×g离心30秒，用微量进样器吸去上清；重复清洗两步，以彻底清洗亲和凝胶；亲和凝胶中加入1mL细胞提取物，4℃，10rpm孵育过夜，4℃，8000×g离心30秒，微量进样器 吸去上清；向亲和凝胶中加入1mL Buffer A，重悬混匀亲和凝胶，4℃下，8000×g离心30 秒，用微量进样器吸去上清，重复操作清洗两次；向亲和凝胶中加入洗脱液，在冰上轻柔震 荡1小时，4℃下，8000×g离心30秒，吸取上清转移到1.5mL干净离心管，上清即为分 离纯化的FLAG标签融合蛋白；另外，各重组蛋白并留样20μL。
S4：抗原的应用。
将上述步骤留样的样品，进行SDS-PAGE检测，且所得蛋白命名为P1-n-P2、P1-n-P3、 P2-n-P3、PnT、TnN、PnN等，其中n＝0、1、2、3、4、5。

选择氨基酸序列为SEQ ID NO.4的PLA2R融合蛋白，简称P。将P、T、N通过连接肽Linker串联在一起，P与T之间连接的linker数目为4，T与N之间连接的linker数目为1，P 与N之间连接的linker数目为4。P、T、N顺序可以互换，但是如果P与T相连，则linker 数目为4，T与N相连，则linker数目为1，如果P与N相连，则linker数目为4，分别命名 为P4T1N、P4N1T、N4P4T、N1T4P、T1N4P和T4P4N，按照试验例1的方法，制备抗原 PLA2R-THSD7A-NELL-1融合蛋白。
按照试验例1的方法，运用各个抗原PLA2R-THSD7A-NELL-1融合蛋白进行抗原-微磁粒 包被及性能测试，检测338例(124例临床结果为膜性肾病患者血清样本和214例健康献血 者血清样本)样本(简称为测试样本)血清中的特异性抗体，比较灵敏度和特异性，实验结 果如下表10所示。表10为抗原PLA2R-THSD7A-NELL-1融合蛋白灵敏度和特异性分析实验 结果。
表10

根据表10的结果，可得，P4T1N对样品检测的特异性、灵敏度均较高，P4T1N简称为PLA2R-THSD7A-NELL-1(P4T1N)。
S7.灵敏度、特异性对比实验。
按照试验例1的方法，对PLA2R-THSD7A-NELL-1(P4T1N)进行抗原-微磁粒包被及性能测试，检测124例临床结果为膜性肾病患者血清样本中抗体的特异性和灵敏度，其中对照试剂盒：抗磷脂酶A2受体抗体IgG检测试剂盒(酶联免疫吸附法)(EA 1254-9601G：96 人份/盒，EUROIMMUN)。结果如下表11所示。
表11
Figure BDA0003620816650000161
本试剂盒检测结果与临床结果符合率95.16％，通过对比结果显示本试剂盒检测的阳性率 均高于单一检测项的试剂盒。较PLA2R单一检测项在灵敏度上由72.58％提升至95.16％。
临床把膜性肾病分为四期，I期为最轻的时期，比较好治疗，IV期为最严重的时期，难 以治愈。从挑选50例有明确临床分期信息的MN血清样本进行试剂盒的特异性和灵敏度测试， 其中对照试剂盒：抗磷脂酶A2受体抗体IgG检测试剂盒(酶联免疫吸附法)(EA 1254-9601G： 96人份/盒，EUROIMMUN)。结果如下表12所示。
表12
Figure BDA0003620816650000162
根据表12的结果可以看出，本试剂盒提升了在轻度膜性肾病患者的检测灵敏度。
使用338例测试样本血清进行检测，使用市场上三款商品化试剂盒与本试剂盒分别检测， 结果显示单独检测的阳性率分别为72.58％、4.84％、6.45％(表13)，本试剂盒的阳性率为 95.16％，通过对比结果显示本试剂盒检测的阳性率均高于单一检测项的试剂盒。结果如下表 13所示。
表13
Figure BDA0003620816650000163
Figure BDA0003620816650000171
根据表13的结果，可以看出，本试剂盒提升了在膜性肾病患者的检测灵敏度。
在测试样本中的24例临床结果为膜性肾病患者血清样本中，有15例弱阳样本，使用基于 细胞的分析(cell-based assay，CBA)的方法学检测均为阳性，其检测抗体比例为1:10或1:64。 以本试剂盒测试以上样本，其中对照试剂盒：抗磷脂酶A2受体抗体IgG检测试剂盒(酶联 免疫吸附法)(EA 1254-9601G：96人份/盒，EUROIMMUN)。结果如下表14所示。
表14
Figure BDA0003620816650000172
可见，本试剂盒有更高的检测灵敏度。本发明的一种诊断膜性肾病的化学发光免疫分析 试剂盒，在不降低试剂灵敏度或特异度条件下，减少试剂盒组分，减少了资源的消耗。试剂 架仅包被PLA2R-THSD7A-NELL-1融合抗原的磁微粒溶液和具有化学发光化合物的标记物 的标记的羊抗人IgG抗体溶液，提升了仪器空间利用率。整个反应过程全自动化操作，简便 易行。提高了反应时间，25min内即可获得诊断结果，结合样本临床信息，诊断结果准确可 靠。
