为了递送包括质粒DNA(pDNA)和短干扰RNA(siRNA)的核酸,已经广泛研究了配备有各种功能的聚合物基因载体。这些聚合物载体的功能已经被设计成克服核酸及其载体在其从注射位点到细胞内靶位点的旅程期间遇到的各种细胞外和细胞内障碍。本文简要介绍了核酸转运的细胞外和细胞内问题及其解决策略。我们检查了影响核酸递送的重要但被忽视的因素(例如,微环境pH值,聚合物/siRNA复合和药物制剂),并强调我们报告的方法来解决这些问题。
To deliver nucleic acids including plasmid DNA (pDNA) and short interfering RNA (siRNA), polymeric gene carriers equipped with various functionalities have been extensively investigated. The functionalities of these polymeric vectors have been designed to overcome various extracellular and intracellular hurdles that nucleic acids and their carriers encounter during their journey from injection site to intracellular target site. This review briefly introduces known extracellular and intracellular issues of nucleic acid delivery and their solution strategies. We examine significant yet overlooked factors affecting nucleic acid delivery (e.g., microenvironmental pH, polymer/siRNA complexation, and pharmaceutical formulation) and highlight our reported approaches to solve these problems.
