通过阳离子聚合物载体在细胞内递送蛋白质治疗药物是一种新兴的技术,然而,它遇到了稳定性差、细胞毒性高和非特异性细胞摄取的问题。在这里,我们提出了一种简单的策略,通过封装线性树突端突来优化蛋白质多阳离子复合物。具有明确结构的端突分子能够合理设计和整合多种功能,从而通过多价和杂化超分子相互作用有效地封装蛋白质-多阳离子复合物,从而生产出低于20纳米的纳米颗粒。这种策略不仅降低了聚阳离子相关的细胞毒性和溶血活性,而且消除了聚阳离子与其他生物大分子的聚集和非特异性结合。此外,在细胞摄取过程中,端突分子很容易与复合物分离,这恢复了细胞内蛋白质递送的聚合能力。这种策略克服了多阳离子载体在细胞内传递蛋白质疗法的局限性。采用合理设计的端突分子包封,可有效地在细胞内递送蛋白质,从而优化蛋白质多阳离子复合物。
Intracellular delivery of protein therapeutics by cationic polymer vehicles is an emerging technique that is, however, encountering poor stability, high cytotoxicity and non-specific cell uptake. Herein, we present a facile strategy to optimize the protein-polycation complexes by encapsulating with linear-dendritic telodendrimers. The telodendrimers with well-defined structures enable the rational design and integration of multiple functionalities for efficient encapsulation of the protein-polycation complexes by multivalent and hybrid supramolecular interactions to produce sub-20 nm nanoparticles. This strategy not only reduces the polycation-associated cytotoxicity and hemolytic activity, but also eliminates the aggregation and non-specific binding of polycations to other biomacromolecules. Moreover, the telodendrimers dissociate readily from the complexes during the cellular uptake process, which restores the capability of polycations for intracellular protein delivery. This strategy overcomes the limitations of polycationic vectors for intracellular delivery of protein therapeutics. A facile strategy to optimize of the protein-polycation complexes was developed by encapsulating with rationally designed telodendrimers for efficient intracellular protein delivery.
