Create IGFBPL1-IGF-1 fusion proteins to exploit IGF-1R-mediated transcytosis machinery at the BBB. Leverages established transport mechanism with structural homology between IGFBPL1 and IGF-binding protein family members.
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.
