JACC:腹主动脉瘤新型纳米疗法的开发

2018-11-22 MedSci MedSci原创

腹主动脉瘤(AAA)是老年死亡和并发症的主要原因之一,目前尚无能有效阻止AAA生长和破裂的药物。本研究的目的旨在开发出一种靶向动脉瘤释放抗炎症因子药物的纳米疗法。本研究的纳米疗法是将活性氧(ROS)响应纳米粒子与候选药物分子雷帕霉素结合起来,并在体外和体内进行了效果的验证。该纳米颗粒会在富含ROS的表面释放药物分子,在与AAA发病相关的细胞中,该纳米疗法可以明显减少钙化水平和ROS介导的细胞凋亡水

腹主动脉瘤(AAA)是老年死亡和并发症的主要原因之一,目前尚无能有效阻止AAA生长和破裂的药物。本研究的目的旨在开发出一种靶向动脉瘤释放抗炎症因子药物的纳米疗法。

本研究的纳米疗法是将活性氧(ROS)响应纳米粒子与候选药物分子雷帕霉素结合起来,并在体外和体内进行了效果的验证。该纳米颗粒会在富含ROS的表面释放药物分子,在与AAA发病相关的细胞中,该纳米疗法可以明显减少钙化水平和ROS介导的细胞凋亡水平。在AAA大鼠中,与对照相比,该纳米疗法可以明显减缓动脉瘤的生长。另外,在前期的安全试验中,该纳米疗法的安全性也得到了证实。

研究结果显示,该新型纳米疗法有望成为腹主动脉瘤的有效治疗手段,值得进一步研究。
