receptor-mediated uptake and apoptosis-mediated cell death in both CD13 receptor-positive pancreatic cancer cells and angiogenic endothelial cells, while the other non-targeting control formulation failed to do so. In a Chick embryo angiogenesis assay, the targeted formulation selectively inhibited angiogenesis, i.e., sprouting of new blood vessels from the pre-existing blood vessels. These finding revealed therapeutic
癌症治疗需要有针对性的有效药物输送,以减少药物介导的不良附带影响。我们在此开发一种新的脂质体递送系统,该脂质体递送系统使用归巢肽(NGR)作为脂质体表面结合的靶向配体,同时靶向CD13受体阳性的癌症上皮和血管生成内皮细胞。配体NGR通过赖氨酸(K)间隔基与C16脂族双链脂质共价缀合后,得到C16-脂肽。重要的是,含有封装有aferin-A(WFA)的NGRKC16-脂肽的循环稳定脂质体在CD13受体阳性的胰腺癌细胞和血管生成内皮细胞中均表现出受体介导的摄取和凋亡介导的细胞死亡。其他非针对性对照制剂则没有这样做。在小鸡胚胎血管生成测定中,靶向制剂选择性抑制血管生成,即从先前存在的血管中萌发新血管。这些发现揭示了WFA-封装的NGRKC16-脂肽脂质体制剂对同时杀死CD13阳性胰腺癌以及血管生成内皮细胞的治疗潜力。由于内皮细胞支持的血管生成与肿瘤上皮细胞的侵袭性是共生相关的,目前描述的CD13
