由聚(β-氨基酯)(PBAE)和聚(乳酸-羟基乙酸)(PLGA)之间的共混物组成的改性纳米颗粒,表面涂覆有细胞穿透肽(CPP),先前已显示出基因递送的前景。在这项研究中,我们试图评估这些修饰的纳米颗粒的肺细胞摄取,并证明其作为肺部基因治疗载体的潜力。这项工作表明,表面改性的PLGA/PBAE/CPP纳米粒子实现了比传统的纳米粒子组成的PLGA或PLGA/PBAE共混物单独更高的细胞缔合。
Modified nanoparticles composed of a blend between poly(β-amino ester) (PBAE) and poly(lactic-co-glycolic acid) (PLGA), surface coated with cell-penetrating peptides (CPPs), have previously shown promise in gene delivery. In this study, we sought to evaluate pulmonary cellular uptake of these modified nanoparticles, and demonstrate their potential as vectors in pulmonary gene therapy. This work shows that surface modified PLGA/PBAE/CPP nanoparticles achieve higher cellular association than traditional nanoparticles composed of PLGA or PLGA/PBAE blends alone.
