The present invention provides compositions and methods for the delivery of therapeutic agents to cells. In particular, these include novel cationic lipids and nucleic acid-lipid particles that provide efficient encapsulation of nucleic acids and efficient delivery of the encapsulated nucleic acid to cells in vivo. The compositions of the present invention are highly potent, thereby allowing effective knock-down of a specific target protein at relatively low doses. In addition, the compositions and methods of the present invention are less toxic and provide a greater therapeutic index compared to compositions and methods previously known in the art.
本发明提供了传递治疗剂到细胞的组成物和方法。特别地,包括新颖的阳离子脂质和核酸-脂质颗粒,提供对核酸的高效封装和对封装的核酸在体内的高效传递到细胞。本发明的组成物非常有效,因此可以在相对较低的剂量下有效地降低特定目标蛋白的表达。此外,本发明的组成物和方法与先前已知的组成物和方法相比,毒性更低,提供更大的治疗指数。
