Compositions and methods for delivering cargo to a target cell

Abstract

Provided herein are compositions, systems, and methods for delivering cargo to a target cell. The compositions, systems, and methods comprise one or more polynucleotides encoding one or more LTR retroelement polypeptides for forming a delivery vesicle and one or more capture moieties for packaging a cargo within the delivery vesicle. The one or more LTR retroelement polypeptides for forming a delivery vesicle may comprise two or more of an LTR retroelement gag protein, a retroelement envelope protein, an LTR retroelement reverse transcriptase, or a combination thereof. The LTR retroelement polypeptide alone, the LTR retroelement envelope protein alone, or both the LTR retroelement-derived polypeptide and LTR retroelement envelope protein may be endogenous. In some embodiments the LTR-retroelement-derived polypeptide is a PNMA polypeptide.
