Description
技术领域
本发明属于细胞免疫技术领域,具体涉及PCV3 Cap蛋白抗原表位肽、抗PCV3 Cap蛋白的单克隆抗体及其制备方法和应用。
背景技术
猪圆环病毒(PCV),是一种无包膜,共价闭合环状单链DNA病毒,被国际病毒分类学委员会(ICTV)归类为圆环病毒科、圆环病毒属。至今,已有四种基因型的猪圆环病毒被报道,即PCV1,PCV2,PCV3和PCV4。1974年,PCV1被作为猪肾(PK15)细胞系的污染物首次发现,而后的研究普遍认为PCV1对猪群中是非致病性的。PCV2,于1997年被发现,其与许多重大临床综合征相关,这些综合征被统称为猪圆环病毒相关疾病(PCVAD)。PCVAD是一种重要的影响经济的猪疾病。考虑到PCV2造成的巨大经济损失,新报告的PCV3和PCV4可能是养猪业的新挑战。
PCV3与急性猪皮炎和肾病综合征(PDNS),生殖衰竭以及心脏和多系统炎症等疾病相关。自2016年以来,PCV3已在包括美国在内的许多国家被广泛发现。值得注意的是,在其他哺乳动物中也检测到了PCV3,例如野猪,小鼠,牛,狗等等。此外,还在蜱虫中检测到PCV3,这些动物可能作为PCV3感染和循环的贮存库,这进一步加大了PCV3的传播速度和跨宿主传播的潜在可能性。系统发育分析表明PCV3与蝙蝠圆环病毒密切相关,暗示PCV3是一种蝙蝠来源的病毒。PCV3的进化动力学表明,与PCV2相比,PCV3的繁殖数(Re)值和进化速率均相对较高,其变异速度接近于RNA病毒。这些研究表明,PCV3可能具有跨物种传播(CST)的能力和连续爆发的可能性。值得关注的是,最近一项研究报道观察到PCV3向狒狒的传播,这暗示着PCV3不仅可能给养猪业带来沉重负担,也可能进化成可以向人类传播的病毒,并严重威胁人类健康。因此,了解和控制该病毒对全球公共卫生至关重要。
Cap蛋白是PCV的唯一结构蛋白。PCV2 Cap蛋白具有良好的免疫原性,并且被广泛作为PCV2疫苗的候选,像PCV2一样,PCV3 Cap蛋白被认为是主要的诊断靶点和疫苗候选。尽管抗血清可从感染PCV3的猪中获得,但由于非特异性有很高的背景,它们不适用于免疫学检测中。迄今为止,分子诊断方法(例如PCR或实时PCR)被普遍用于检测PCV3。然而,由于缺乏PCV3特异性单克隆抗体,用于检测PCV3的免疫学诊断方法还较少。开发抗PCV3Cap单克隆抗体对免疫学检测方法的建立和PCV3生物学特性的研究必不可少。
目前亟需制备出一种与PCV1、PCV2和其他猪源病毒均无交叉反应且可以同时用于多种免疫检测手段的PCV3单克隆抗体,进而确定其重链可变区序列和轻链可变区序列以改造其抗体可变区序列制备不同组合形式的基因工程抗体,以期进一步提升抗体的特异性和亲和力。
