This approach leverages thermosensitive liposomes (TSLs) loaded with IGFBPL1 that undergo controlled drug release when exposed to mild hyperthermia (40-45°C) generated by focused ultrasound. The liposomes are formulated with temperature-sensitive phospholipid compositions, particularly dipalmitoylphosphatidylcholine (DPPC) and lysolipids, which undergo phase transitions at specific temperatures, creating membrane permeability changes that enable rapid drug release within 10-20 seconds of heating
**Molecular Mechanism and Rationale**
The lentiviral-mediated delivery of IGFBPL1 to astrocytes utilizes the neurotropic properties of pseudotyped lentiviral vectors and GFAP promoter specificity to target reactive astrocytes in neuroinflammatory conditions. Unlike AAV systems, lentiviruses integrate into the host genome, providing sustained long-term expression that is particularly advantageous for chronic neurodegenerative diseases. The VSV-G pseudotyped lentiviral particles bind to low-densi
