在这篇综述中,我们专注于细胞膜脂质的生物物理学,特别是当癌症发展获得性耐药性,以及耐药细胞膜的生物物理变化如何影响药物转运和纳米颗粒介导的药物递送。膜脂质研究的最新进展表明,脂质在调节膜P-糖蛋白功能、膜运输、凋亡途径、药物转运和内吞功能,特别是内吞作用(基于纳米颗粒的药物递送系统的细胞摄取的主要机制)中的不同作用。由于获得性耐药性改变脂质生物合成,了解脂质在细胞膜生物物理学中的作用及其对药物转运的影响对于开发克服耐药性的有效治疗和药物递送方法至关重要。在这里,我们讨论了新的策略(a)调节耐药细胞的膜脂质的生物物理特性,以促进药物转运和恢复内吞功能和(B)开发有效的纳米粒子的基础上,其与膜脂质的生物物理相互作用,以增强药物输送和克服耐药性。
In this review, we focus on the biophysics of cell membrane lipids, particularly when cancers develop acquired drug resistance, and how biophysical changes in resistant cell membrane influence drug transport and nanoparticle-mediated drug delivery. Recent advances in membrane lipid research show the varied roles of lipids in regulating membrane P-glycoprotein function, membrane trafficking, apoptotic pathways, drug transport, and endocytic functions, particularly endocytosis, the primary mechanism of cellular uptake of nanoparticle-based drug delivery systems. Since acquired drug resistance alters lipid biosynthesis, understanding the role of lipids in cell membrane biophysics and its effect on drug transport is critical for developing effective therapeutic and drug delivery approaches to overcoming drug resistance. Here we discuss novel strategies for (a) modulating the biophysical properties of membrane lipids of resistant cells to facilitate drug transport and regain endocytic function and (b) developing effective nanoparticles based on their biophysical interactions with membrane lipids to enhance drug delivery and overcome drug resistance.
