Focused Ultrasound with Microbubble Contrast Agents for Antibody CNS Delivery

h-013cc31a80

FUS with systemically administered microbubbles induces localized, reversible BBB disruption via mechanical cavitation effects, triggering Akt phosphorylation and tight junction protein disassembly. When combined with therapeutic antibodies, synergistic brain penetration achieves 50-fold greater exposure than either approach alone. The technology leverages FDA-approved microbubble agents and MRI-g
