开发治疗性生物大分子的安全有效的递送系统是一个长期的挑战。在此,我们报告了一个新开发的胆固醇基的含二硫键的可生物降解的阳离子类胡萝卜素纳米颗粒的组合库。我们已经鉴定了该文库的一个子集,其对于体外和体内的蛋白质和mRNA递送是有效的。与体外Lpf2k相比,这些类胡萝卜素显示出相当的转染效率,但细胞毒性低得多。在成年小鼠中的体内研究证明了基因组工程蛋白和mRNA分子在骨骼肌(通过肌内注射)、肺和脾(通过静脉内注射)和脑(通过侧脑室输注)中的成功递送。细胞内递送:一种新的基于胆固醇的和还原响应的类胡萝卜素纳米颗粒的组合文库可以在体外和体内递送基因组工程蛋白和mRNA分子。使用成年Ai14小鼠模型,通过局部和全身给药,在骨骼肌、脑、肺和脾中观察到成功的Cre介导的基因重组事件。
Developing safe and efficient delivery systems for therapeutic biomacromolecules is a long-standing challenge. Herein, we report a newly developed combinatorial library of cholesteryl-based disulfide bond-containing biodegradable cationic lipidoid nanoparticles. We have identified a subset of this library which is effective for protein and mRNA delivery in vitro and in vivo. These lipidoids showed comparable transfection efficacies but much lower cytotoxicities compared to the Lpf2k in vitro. In vivo studies in adult mice demonstrated the successful delivery of genome engineering protein and mRNA molecules in the skeletal muscle (via intramuscular injection), lung and spleen (via intravenous injection), and brain (via lateral ventricle infusion). Intracellular delivery: a new combinatorial library of cholesteryl-based and reduction-responsive lipidoid nanoparticles can deliver genome engineering protein and mRNA molecules in vitro and in vivo. Using adult Ai14 mouse model, successful Cre-mediated gene recombination events were observed in skeletal muscle, brain, lung, and spleen through the local and systemic administrations.
