A process is provided of delivering at least one active agent cargo molecule into an neuronal cell whereby a cargo molecule is placed within a synthetic vesicle such as a liposome and a biotinylated protein such as an antibody is bound to the synthetic vesicle to form a protein bound synthetic vesicle whereby the protein recognizes a receptor expressed on the surface of a neuronal cell, and exposing the protein bound synthetic vesicle to the cell until the cargo molecule is delivered into the neuronal cell. Numerous cargo molecules are delivered by the inventive synthetic vesicle including a calpain inhibitor and a caspase inhibitor. The protein illustratively targets a cellular receptor for a ligand such as glutamate, glycine, dopamine, nicotine, muscarine, acetylcholine, or serotonin, and the like.

Linvention concerne un procédé de délivrance dau moins une molécule cargo dagent actif dans une cellule neuronale, selon lequel une molécule cargo est placée dans une vésicule synthétique telle quun liposome et une protéine biotinylée, telle quun anticorps, est reliée à la vésicule synthétique pour former une vésicule synthétique reliée à une protéine. Selon le procédé de linvention, la protéine reconnaît un récepteur exprimé sur la surface dune cellule neuronale et expose la vésicule synthétique reliée à la protéine à la cellule jusquà ce que la molécule cargo ait été délivrée dans la cellule neuronale. De nombreuses molécules cargo sont délivrées par la vésicule synthétique de linvention, y compris un inhibiteur de calpain et un inhibiteur de caspase. La protéine cible par exemple un récepteur cellulaire pour un ligand tel que glutamate, glycine, dopamine, nicotine, muscarine, acétylcholine ou sérotonine, et analogue.
