The preparation and use of a transducing polypeptide (TP)— lipid vesicle complex having a small proportion of positively charged (cationic) lipids in the make-up of the lipid vesicle, e.g., liposome, for safe and efficient intracellular delivery of therapeutic agents, such as proteins, DNA, small molecules and/or other drugs, into a cell of a higher organism, in vitro or in vivo is disclosed. The delivery system of the invention results in increased efficacy of intracellular delivery of such agents, bypassing the endocytotic pathway of intracellular delivery while at the same time minimizing the toxicity of the delivery system towards the recipient cells.
本发明揭示了一种转导多肽(TP)-脂质体复合物的制备和使用方法,该复合物在脂质体的构成中含有一小部分带正电(阳离子)脂质,例如脂质体,可安全有效地将治疗剂,例如蛋白质、DNA、小分子和/或其他药物,递送到高等生物的细胞内,无论是体外还是体内。本发明的递送系统可以提高这些剂量的细胞内递送的效力,同时绕过内吞途径,同时最小化递送系统对接受细胞的毒性。
