Abstract
The present invention discloses a liposome formulation, its preparation method, and its application in the treatment of diseases caused by abnormal gene expression. The liposome formulation comprises complementary cationic lipid pairs, phospholipids, and long-circulating lipids. The method of preparing the liposome formulation comprises: mixing the complementary cationic lipid pairs with the phospholipid and the long-circulating lipid to generate pre-formed vesicles; and then mixing the pre-formed vesicles with the nucleic acid solution to generate the liposome-nucleic acid formulation. This liposome formulation provided by the present invention is easily prepared; and in the treatment of diseases caused by abnormal gene expression, the liposome formulation can be used to deliver in vivo therapeutic agents, including nucleic acids.
