**Molecular Mechanism and Rationale**
The AAV-PHP.eB-mediated delivery of IGFBPL1 to astrocytes leverages the neurotropic properties of engineered AAV capsids combined with GFAP (Glial Fibrillary Acidic Protein) promoter-driven specificity for astrocytic compartments in the central nervous system. This approach exploits astrocytes' unique position as the most abundant glial cell type and their critical role in maintaining blood-brain barrier integrity, synaptic function, and neurometabolic coup
**Molecular Mechanism and Rationale**
The AAV-PHP.eB-mediated delivery of IGFBPL1 to microglia exploits a sophisticated molecular targeting strategy based on the unique neurotropic properties of engineered adeno-associated virus capsids and the CX3CR1-mediated specificity for myeloid cells in the central nervous system. IGFBPL1 (Insulin-like Growth Factor Binding Protein-Like 1) functions as a multifaceted regulatory protein that modulates insulin-like growth factor (IGF) signaling, extracellul
