Apply FUS focused on hippocampus/cortex regions to temporarily open the BBB via microbubble cavitation, creating transient paracellular gaps allowing IV-administered IGFBPL1 protein to reach CNS microglia with spatial precision tunable to treatment regions.
Deliver IGFBPL1 gene via AAV vectors that cross the BBB (AAV-PHP.eB or AAV9) with microglial-specific promoters (CX3CR1, TMEM119, P2RY12) for targeted expression. This approach bypasses the need for BBB penetration by protein delivery entirely, instead enabling endogenous IGFBPL1 production specifically in microglia.
