Abstract: Some embodiments of the invention include pseudotyped particles (e.g., pseudo typed exosomes, pseudotyped VSV, and pseudo typed lentiviruses) and modified cells. Other embodiments of the invention include compositions (e.g., pharmaceutical compositions) of pseudotyped particles (e.g., pseudotyped exosomes, pseudotyped VSV, and pseudotyped lentiviruses) and modified cells. Certain embodiments of the invention include methods of making pseudotyped particles (e.g., pseudotyped exosomes, pseudotyped VSV, and pseudotyped lentiviruses) and modified cells. Other embodiments of the invention include methods of administering pseudotyped particles (e.g., pseudotyped exosomes, pseudotyped VSV, and pseudotyped lentiviruses). Further embodiments of the invention include methods of administering pseudotyped particles (e.g., pseudotyped exosomes, pseudotyped VSV, and pseudotyped lentiviruses) to treat diseases (e.g., muscular dystrophy). Additional embodiments of the invention are also discussed herein.
