项目摘要
In this study, we developed the self-assembly nano-devices based on electrostatic interaction. We could prepare the stable nano-devices by changing the blend ratio of gene, cationic compounds and anionic compounds and the preparation procedures. The nano-devices containingγ-polyglutamic acid, N-lauroylsarcosine, or glycyrrhizin achieved high intracellular uptake without showing cytotoxicity and blood toxicity. After intravenous administration of these nano-devices in mice, selective high gene expression was observed in the spleen, lung, or liver by the difference of each component. Furthermore, we could mass-produce and freeze-dry nano-devices. In conclusion, we successfully developed the secure and effective nano-devices and revealed the preparation technic responding to therapeutic purpose.
本研究开发了基于静电相互作用的自组装纳米器件,通过改变基因、阳离子化合物和阴离子化合物的混合比例以及聚谷氨酸、N-月桂酰肌氨酸的制备过程来制备稳定的纳米器件。或甘草甜素实现了高细胞内摄取,且未表现出细胞毒性和血液毒性。在小鼠体内静脉注射这些纳米装置后,选择性高基因表达。通过在脾脏、肺或肝脏中观察到每个成分的差异,我们可以批量生产和冷冻干燥纳米器件。 总之,我们成功开发了安全有效的纳米器件并揭示了制备技术。响应治疗目的。
