Even more impressive, the researchers showed that exosomes can be made to ferry anti-inflammatory drugs, which diffused very rapidly after entering the brain.
"If development of exosomes as a carrier system will be pursued, it could generate a valuable strategy for treatment of CNS diseases that were previously considered as untreatable," Heijnen says.
