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.
本发明提供了用于向细胞输送治疗剂的组合物和方法。特别是,这些包括新型阳离子脂质和核酸-脂质颗粒,它们可以有效地封装核酸并将封装的核酸有效地输送到体内的细胞中。本发明的组合物具有高度的效力,因此可以在相对较低的剂量下有效地敲低特定靶蛋白。此外,与先前已知的组合物和方法相比,本发明的组合物和方法毒性较小,并提供更大的治疗指数。
