**Molecular Mechanism and Rationale**
The AAV-PHP.eB-mediated delivery of IGFBPL1 to astrocytes leverages the neurotropic properties of engineered AAV capsids combined with GFAP (Glial Fibrillary Acidic Protein) promoter-driven specificity for astrocytic compartments in the central nervous system. This approach exploits astrocytes' unique position as the most abundant glial cell type and their critical role in maintaining blood-brain barrier integrity, synaptic function, and neurometabolic coup
This hybrid approach combines focused ultrasound (FUS) microbubble-mediated blood-brain barrier (BBB) disruption with AAV-PHP.eB viral vectors carrying CX3CR1-driven IGFBPL1 expression cassettes to achieve enhanced microglial-specific therapeutic delivery. The molecular mechanism begins with systemic administration of perfluorocarbon microbubbles (1-10 μm diameter) followed by targeted FUS application at 0.2-1.5 MHz to specific brain regions. Acoustic cavitation generates localized mechanical st
