Topic: Precision Targeting and Blood-Brain Barrier Penetration of Extracellular Vesicles

Precision targeting includes the development of delivery systems that specifically target desired cells or tissues, minimizing off-target effects and improving the overall efficacy of therapeutic interventions. This approach often utilizes various targeting ligands or surface modifications to guide drug-loaded vesicles to their intended destination with high specificity. The blood-brain barrier (BBB) is a highly selective barrier that protects the brain from circulating toxins and pathogens but poses a challenge for drug delivery to the central nervous system (CNS). Overcoming the BBB is crucial for the therapy of neurological diseases. Extracellular vesicles (EVs), such as exosomes, have gained attention as potential carriers for drug delivery due to their natural ability to transport cargo between cells. Strategies to enhance BBB penetration involve optimizing the properties of EVs or incorporating specific modifications that facilitate their transport across the BBB. Precision targeting and BBB penetration in the context of EVs will provide promising avenues for the development of more effective and targeted therapies, particularly in the area of neurodegenerative disorders and other diseases affecting the CNS.
