Abstract

This invention provides artificial viral envelopes and other lipid vesicles that encapsulate therapeutic substances, such as expression vectors, targeted to mammalian cells. Polynucleotides may be packed into the envelopes by compressing them beforehand with a short peptide with a predominant positive charge. The compression step not only facilitates encapsulation, it also increases the number of vesicles containing nucleic acid, minimizes the amount of free nucleic acid, and may also increase the size and complexity of plasmids that can be encapsulated. The vesicles may be provided with a tissue targeting component that helps direct it towards certain tissue sites in an animal. The vesicles may also be provided with a fusogenic component that facilitates delivery of the therapeutic substance into the cell. The materials and reagents of this invention are effective, for example, in increasing expression of model proteins in both isolated cells and intact animals, and are expected to be useful for gene therapy.
