Abstract (EN): In the last decades, it has been recognized that extracellular vesicles (EVs) are not only cell debris with no biological role, but instead they play a key role in information exchange between cells either in health and disease conditions. EVs exhibit indeed their biological role in a pleiotropic manner. They can modulate immune responses through the activation, transfer or removal of surface receptors on target cells, the removal of cytolytic components such as membrane attack complexes, and the transfer of signaling molecules/effectors, such as nucleic acid species, infectious particles, and oncogenes. Among the naturally-derived nanoparticles that have been developed in the last years, stimuli responsive exosomes drew special attention since they intrinsically possess many attributes of a desirable drug delivery system. Their small size allows them to bypass the mononuclear phagocytic system (MPS) clearance, thereby prolonging their circulation time for passive targeting to inflammatory tissues. Moreover, they can deliver their cargo directly into the cytosol, avoiding the lysosomal/endosomal pathway and thus, increasing the transfection efficiency when they are used as gene delivery systems. of This review offers the state of the art knowledge on the physiology and properties of EVs, namely, apoptotic vesicles, microvesicles and exosomes as innovative drug delivery systems for gene therapy, with a special focus on targeting dendritic cells for the treatment of autoimmune disorders.
