*Golden Exosomes Selectively Target Pathological Brain Regions*

Exosomes enable intercellular communication at local or distant sites. Although they have been found to cross the blood brain barrier, their migration and homing abilities within the brain remain unstudied. We have recently developed a method for longitudinal and quantitative in vivo neuroimaging of exosomes based on the superior visualization abilities of classical X-ray computed tomography (CT), combined with gold nanoparticles as labeling agents. We used this technique to track the migration and homing patterns of intranasally administrated exosomes derived from bone marrow mesenchymal stem cells in different brain pathologies, including stroke, autism, Parkinson’s disease, and Alzheimer’s disease. We found that these exosomes specifically targeted and accumulated in pathologically relevant murine models brains regions. The exosome homing mechanism is inflammatory-driven, and the exosomes are selectively uptaken by neuronal cells in the pathological regions.
These findings have important implications for using exosomes as targeted drug carriers in various brain pathologies.
