基因传递有可能治疗一系列遗传性和获得性疾病。由于病毒对细胞的有效感染以及长期的基因表达,研究主要集中在使用病毒载体来实现这一目的。然而,病毒载体用于基因治疗的使用受到安全担忧、生产/制造挑战以及有限的核酸携带能力的限制[1,2]。因此,包括阳离子聚合物在内的生物材料作为基因转染剂[3-5]受到越来越多的关注,因为它们与质粒DNA形成阳离子纳米颗粒的静电相互作用。聚合物,包括聚乙烯亚胺(PEI),在各种基因治疗应用中都很有用[6-10]。
Gene delivery has the potential to treat a range of inherited and acquired diseases. Research has primarily focused on the use of viral vectors for this purpose, due to efficient infection of cells with viruses as well as long-term gene expression. However, the use of viral vectors for gene therapy is limited by safety concerns, production/manufacturing challenges, and limited nucleic acid carrying capacity [1, 2]. Thus, increased attention has been focused on biomaterials including cationic polymers as gene transfection agents [3-5] due totheir electrostatic interactions with plasmid DNA to form cationic nanoparticles. Polymers, including polyethylenimine (PEI), are useful in a variety of gene therapy applications [6-10].
