Abstract[English]
The present invention relates to engineered extracellular vesicles. More specifically, the present invention relates to an isolated EV comprising a fusogenic protein, a binding moiety to a cell membrane protein, and a molecule of interest, wherein the fusogenic protein and the binding moiety are displayed on the EV separately. The EV disclosed in the present invention shows improved intracellular delivery efficiency. The present invention also relates to a pharmaceutical composition comprising the EV and a method of delivering a molecule of interest to a recipient cell.[French]
La présente invention concerne des vésicules extracellulaires modifiées. Plus spécifiquement, la présente invention concerne un VE isolée comprenant une protéine fusogène, une fraction de liaison à une protéine de membrane cellulaire, et une molécule d'intérêt, la protéine fusogène et la fraction de liaison étant exposées séparément sur la VE. La VE décrite dans la présente invention présente une efficacité d'administration intracellulaire améliorée. La présente invention concerne également une composition pharmaceutique comprenant la VE et un procédé d'administration d'une molécule d'intérêt à une cellule receveuse.
