Deliver IGFBPL1 protein or peptide fragments intranasally with permeation enhancers (cyclodextrins, chitosan) to bypass BBB entirely via olfactory and trigeminal nerve pathways, reaching olfactory bulb and subsequent microglial populations.
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.
