Abstract

背景及目的 肝癌是目前世界上最常见的恶性肿瘤,高居癌症致死原因中的第三位。它的五年存活率是7%,每年可导致六十万人死亡。肝癌的治疗方法目前主要有手术、放化疗及中医药治疗,但是对于中晚期肝癌治疗效果都不能取得满意的治疗效果。生物蛋白纳米粒免疫治疗作为一种新的治疗方法,虽然在临床上还不够成熟,但它在癌症治疗中具有较好的研究前景。 我们现有的研究证实,抗人DR5单链抗体(aDR5ScFv)可通过与DR5特异性结合,诱导表达DR5的肿瘤细胞凋亡,并且抗人DR5单链抗体无肝毒性。也有研究发现,单链抗体血浆半衰期短,在作用位点不能长期维持高浓度,并且抗体在体外容易降解和缓释,因而需要寻找一种优良的载体...Background & objective Liver cancer is the most common malignancy in the world, and ranks third place in the cancer cause of death.
