Description
技术领域
本发明属于生物医药领域,尤其是涉及一种TROP-2特异性纳米抗体及其应用。
背景技术
研究报道,肿瘤相关钙信号转导蛋白2(TROP-2)在许多肿瘤组织的表达水平显著高于正常组织,其过表达与乳腺癌、胰腺癌、卵巢癌和前列腺癌等恶性肿瘤的预后不良、患者生存期缩短等密切相关。目前靶向TROP-2抗肿瘤的研究大多基于单克隆抗体药物,但由于其高成本和生产过程的复杂性以及相对较大的尺寸阻止mAb渗透到实体瘤组织中,并导致全身积累等,所以单克隆抗体的应用受到了一定的限制。在驼源动物外周血液中天然存在一种重链抗体(Heavy Chain only Antibodies,HCAbs),与传统单克隆抗体相比,重链抗体天然缺失轻链及重链第一恒定区(CH1),克隆并表达重链抗体的重链可变区得到重链抗体的抗原识别和结合域,称为纳米抗体(Nanobody, Nb),作为最小的天然抗体(12-15kDa),纳米抗体具有适合诊疗开发的独特特性。首先小分子尺寸使纳米抗体相对容易渗透到组织中,穿过血脑屏障;其次在保持对抗原的高结合亲和力的同时,纳米抗体长而灵活的CDR3区允许与靶抗原的裂缝和空腔结合,因此,纳米抗体可以识别其他抗体难以识别的隐藏表位;此外,纳米抗体可以更方便地设计成多个功能域以产生多价/多特异性纳米抗体,从而获得更多的治疗应用功能;除以上所述,纳米抗体还具有可溶性极高,不易发生聚集沉淀,具有很高的稳定性,能够在高温、强酸、强碱等致变性条件下保持抗原结合活性,适合于原核及真核表达系统等优势,因此,纳米抗体更适合开发临床诊疗体系。
