    Due to the existence of the blood-brain barrier (BBB) and the complicated pathological mechanisms of Alzheimer's disease (AD), current therapeutic approaches for AD show limited efficacy. To overcome these challenges, a multi-strategy drug delivery system (SA-BP-MB/BBR NPs) was developed: photothermal conversion polydopamine nanoparticles (PDA NPs) were decorated with sialic acid-modified bovine serum albumin (SA-BSA) to prepare SA-modified and BSA-stabil... ...点击完成人机验证后继续浏览

    由于血脑屏障(BBB)的存在以及阿尔茨海默病(AD)复杂的病理机制,目前用于治疗AD的方法效果有限。为了克服这些挑战,开发了一种多策略药物递送系统(SA-BP-MB/BBR NPs),具体方法为:通过修饰牛血清白蛋白(BSA)的唾液酸(SA-BSA)来装饰光热转换聚多巴胺纳米粒子(PDA NPs),制备了针对BBB的目标唾液酸修饰和BSA稳定的PDA纳米颗粒(SA-BP NPs)。在此基础上,与光敏剂亚甲基蓝(MB)和小檗碱(BBR)共负载,以靶向多种神经病理因素,包括Aβ聚集和tau过度磷酸化。制备的SA-BP-MB/BBR NPs具有球形形态,粒径均匀,平均直径为143.43 nm,多分散性指数(PDI)为0.095。药物负载能力分别为MB 6.98%和BBR 3.50%。研究结果表明,在结合光热疗法和光动力疗法的情况下,生物相容性的SA-BP-MB/BBR NPs的细胞摄取效率提高了1.74倍,这有效地抑制了Aβ聚集、Aβ纤维解聚以及tau过度磷酸化。药代动力学和体内生物分布研究表明,与自由的MB和BBR相比,SA-BP-MB/BBR NPs具有更高的曲线下面积(AUC0-t),分别高出9.75倍和7.52倍,并且唾液酸修饰促进了脑部积累。总体而言,SA-BP-MB/BBR NPs有可能成为AD的有效治疗方法。
