The molecular foundation of magnetofection-mediated IGFBPL1 delivery exploits superparamagnetic iron oxide nanoparticles (SPIONs) complexed with therapeutic protein cargo to achieve targeted brain delivery through magnetically-guided transport and enhanced cellular uptake. SPIONs (10-100 nm diameter) consisting of magnetite (Fe₃O₄) cores with biocompatible polymer shells (polyethylene glycol or dextran) are conjugated to recombinant IGFBPL1 through covalent linkage or electrostatic interaction.
**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
