Focused Ultrasound–Mediated Brain Genome Editing

Gene editing in the brain has been challenging because of the restricted transport imposed by the blood–brain barrier (BBB). In this study, investigators described a safe and effective gene‑editing technique by using focused ultrasound (FUS) to transiently open the BBB for the transport of intravenously delivered CRISPR machinery to the brain in mice. By combining FUS with adeno-associated virus–mediated gene delivery, researchers can achieve more than 25% editing efficiency of particular cell types. This method has the potential to expand toolkit options for CRISPR delivery and opens opportunities for treating diseases of the brain, such as neurodegenerative disorders, with somatic genome editing.

AAV Capsid Variants with Brain-Wide Transgene Expression and Decreased Liver Targeting After Intravenous Delivery in Mouse and Marmoset

Genetic intervention is increasingly being explored as a therapeutic option for debilitating disorders of the central nervous system (CNS). This project focused on organ-specific targeting of adeno-associated virus (AAV) capsids after intravenous delivery. These results constitute an important step forward toward achieving the goal of engineered AAV vectors that can be used to broadly deliver gene therapies to the CNS in humans.
