Over the years, there has been significant interest in PEGylated lipid-based nanocarriers within the drug delivery field. The inevitable interplay between the nanocarriers and plasma protein plays a pivotal role in their biological fate. Understanding the factors influencing lipid-based nanocarrier and protein corona interactions is of paramount importance in the design and clinical translation of these nanocarriers. Herein, discoid-shaped lipid nanodiscs (sNDs) composed of different phospholipids with varied lipid tails and head groups were fabricated. We investigated the impact of phospholipid components on the interaction between sNDs and serum proteins, particle stability, and biodistribution. The results showed that all of these lipid nanodiscs remained stable over a 15 day storage period, while their stability in the blood serum demonstrated significant differences. The sND composed of POPG exhibited the least stability due to its potent complement activation capability, resulting in rapid blood clearance. Furthermore, a negative correlation between the complement activation capability and serum stability was identified. Pharmacokinetic and biodistribution experiments indicated that phospholipid composition did not influence the capability of sNDs to evade the accelerated blood clearance phenomenon. Complement deposition on the sND was inversely associated with the area under the curve. Additionally, all lipid nanodiscs exhibited dominant adsorption of apolipoprotein. Remarkably, the POPC-based lipid nanodisc displayed a significantly higher deposition of apolipoprotein E, contributing to an obvious brain distribution, which provides a promising tool for brain-targeted drug delivery.
多年来,在药物传递领域,聚乙二醇化脂质基纳米载体引起了人们的极大兴趣。纳米载体与血浆蛋白之间不可避免的相互作用在它们的生物学命运中起着关键作用。了解影响脂质基纳米载体与蛋白冠相互作用的因素对于这些纳米载体的设计和临床转化至关重要。本文制备了由不同磷脂组成的盘状脂质纳米盘(sND),这些磷脂具有不同的脂质尾部和头部基团。我们研究了磷脂成分对 sND 与血清蛋白相互作用、颗粒稳定性和体内分布的影响。结果表明,所有这些脂质纳米盘在 15 天的储存期内保持稳定,而它们在血清中的稳定性存在显著差异。由于具有强大的补体激活能力,POPG 组成的 sND 表现出最低的稳定性,导致血液清除迅速。此外,还确定了补体激活能力与血清稳定性之间存在负相关。药代动力学和体内分布实验表明,磷脂组成并不影响 sND 逃避加速血液清除现象的能力。补体在 sND 上的沉积与曲线下面积呈负相关。此外,所有的脂质纳米盘都表现出载脂蛋白的主要吸附。值得注意的是,基于 POPC 的脂质纳米盘显示出明显更高的载脂蛋白 E 的沉积,导致明显的脑分布,为脑靶向药物传递提供了一种很有前途的工具。
