Sci Transl Med:纳米颗粒灌注技术帮助解决器官移植问题

2017-12-04 药明康德 学术经纬

研究人员将纳米颗粒技术和体外灌流 (ex vivo perfusion) 技术结合在一起,能够在体外通过对移植器官进行灌流,将携带治疗器官缺陷药物的纳米颗粒运送到到EC附近。

因为器官暂时缺血而造成的损伤一直是限制移植器官存活性的主要问题。而器官中的血管内皮细胞(endothelial cells, ECs) 是移植后最先接触到宿主免疫系统的细胞。ECs是缺血造成损伤和抗供体抗体 (antidonor antibodies) 的首要靶点。减少移植过程前后ECs的损伤对减弱宿主对移植器官的免疫反应有着长期效益。耶鲁大学 (Yale University) 的研究人员开发出一种新型纳米颗粒,通过在纳米颗粒表面镶嵌CD31抗体,它们能够有特异性地富集在EC表面。研究人员将纳米颗粒技术和体外灌流 (ex vivo perfusion) 技术结合在一起,能够在体外通过对移植器官进行灌流,将携带治疗器官缺陷药物的纳米颗粒运送到到EC附近。这项技术意味着医生们可以在将器官植入患者体内之前在体外对器官进行治疗,改善它们在移植后存活的可能性,从而提高器官移植的成功率并且增加可移植器官的数量。
