脂质纳米颗粒(LNP)是具有可调物理化学性质的通用结构,其理想地适合作为疫苗递送和RNA治疗的平台。LNP合理设计的一个关键障碍是不能将组成和结构与细胞内加工和功能联系起来。单粒子自动拉曼捕获分析(斯巴达)与小角X射线和中子散射(SAXS/SANS)技术相结合,将LNP组成与内部结构和形态联系起来,并监测动态LNP−磷脂酶D(PLD)相互作用。该分析表明,PLD,一种关键的细胞内运输介质,可以进入整个LNP脂质膜,以产生稳定的阴离子LNP。PLD活性的囊泡与匹配量的酶底物是一个数量级较低,表明LNP脂膜结构可用于控制酶的相互作用。这代表了设计酶响应LNP解决方案用于刺激响应递送和PLD失调的疾病的机会。
Lipid nanoparticles (LNPs) are versatile structures with tunable physicochemical properties that are ideally suited as a platform for vaccine delivery and RNA therapeutics. A key barrier to LNP rational design is the inability to relate composition and structure to intracellular processing and function. Here Single Particle Automated Raman Trapping Analysis (SPARTA) is combined with small-angle X-ray and neutron scattering (SAXS/SANS) techniques to link LNP composition with internal structure and morphology and to monitor dynamic LNP−phospholipase D (PLD) interactions. This analysis demonstrates that PLD, a key intracellular trafficking mediator, can access the entire LNP lipid membrane to generate stable, anionic LNPs. PLD activity on vesicles with matched amounts of enzyme substrate is an order of magnitude lower, indicating that the LNP lipid membrane structure can be used to control enzyme interactions. This represents an opportunity to design enzyme-responsive LNP solutions for stimuli-responsive delivery and diseases where PLD is dysregulated.
