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
This approach leverages thermosensitive liposomes (TSLs) loaded with IGFBPL1 that undergo controlled drug release when exposed to mild hyperthermia (40-45°C) generated by focused ultrasound. The liposomes are formulated with temperature-sensitive phospholipid compositions, particularly dipalmitoylphosphatidylcholine (DPPC) and lysolipids, which undergo phase transitions at specific temperatures, creating membrane permeability changes that enable rapid drug release within 10-20 seconds of heating
