Delivering genes to and across the brain vasculature efficiently and specifically across species remains challenging. Here, the authors show that endothelial-specific AAVs with serotype flexibility enable redosing and transform the brain vasculature into an in vivo biofactory in genetically diverse rodents. In primates, these vectors cross the blood-brain-barrier and show broad tropism.
