1287-脂质纳米颗粒蛋白冠分析面临的挑战与策略

from 聊聊Sci

这份研究探讨了可电离脂质纳米颗粒 (LNPs) 在进入生物流体后,其表面形成的蛋白冠 (Protein Corona) 与传统纳米颗粒之间的显著差异。作者指出,LNPs 的生物界面并非像硬质纳米颗粒那样形成一层稳固的外壳结构,而是更多地表现为与脂蛋白及胞外囊泡的融合与集成。研究强调,这种“融合型”蛋白冠受到脂质配方和环境因素的精密调控,是决定药物能否实现非肝脏器官靶向的关键动力。由于 LNPs 与血液成分在物理特性上高度相似,传统的分离与分析技术常面临杂质干扰与数据误读的挑战。因此,文中提倡开发更精准的蛋白质组学策略和冷冻电镜可视化方法,以便真实还原 LNPs 的生物身份。最终,这种从“吸附模型”向“融合模型”的认知转变,将为设计更高效的核酸药物递送系统提供理论支持。References:Borhan B, Murray A M, Saei A A, et al.
