Cancer Immunol Immunother:DNA编码的抗前列腺特异膜抗原单克隆抗体的新的前列腺癌免疫疗法

2017-08-25 AlexYang MedSci原创

前列腺特异膜抗原(PSMA)在恶性肿瘤前列腺细胞中高水平表达,并且很可能是前列腺恶性肿瘤治疗的一个重要的药物靶标。目前已PSMA为治疗靶标的免疫疗法包括肽、细胞、载体或者基于DNA的疫苗以及PSMA特异性单克隆抗体(mAb)被动治疗。传统的mAb免疫治疗具有很多的逻辑和实践限制,包括高额的生产费用和由于短的mAb血清半衰期而导致的频繁剂量输入。最近,有研究人员阐释了一个基于抗体的免疫疗法的新的治疗

传统的mAb免疫治疗具有很多的逻辑和实践限制,包括高额的生产费用和由于短的mAb血清半衰期而导致的频繁剂量输入。最近,有研究人员阐释了一个基于抗体的免疫疗法的新的治疗前列腺恶性肿瘤的治疗方法,该方法利用合成的DNA质粒来编码以PSMA为靶标的治疗性人类mAb。在小鼠中电穿孔肌肉内注射DNA编码的mAb质粒可以稳定和持续的产生功能性的抗PSMA抗体。另外,PSMA抗体在体内试验中的产生控制了肿瘤的生长,并且延长了小鼠模型生存期。这很可能由抗体依赖的有NK细胞协助的细胞毒性(ADCC)影响来调控。最后,研究人员指出,该新方法在治疗人类前列腺癌和其他恶性肿瘤中的进一步的研究是需要的。

在转移过程中,肿瘤细胞迁移出它们原来的组织入侵到其他器官中。外泌体和金属蛋白酶的分泌对细胞外基质重塑是必需的,从而促使通过组织障碍的成功迁移。转移性前列腺癌可以由稀有的分子马达肌凝蛋白IC的同种型A的表达来区分,然而,该同种型的功能仍旧未知。最近,有研究人员进行的研究表明该同种型可以利于前列腺癌细胞侵入的运动性。另外,研究人员还发现该同种型与包含金属蛋白酶的外泌体有联系并且刺激它们的分泌。尽管数据
