**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
## **Molecular Mechanism and Rationale**
The molecular foundation of focused ultrasound (FUS) with microbubble contrast agents relies on the precise manipulation of acoustic cavitation to temporarily disrupt the blood-brain barrier (BBB) architecture. The BBB consists of specialized endothelial cells connected by tight junction proteins including claudin-5, occludin, and zonula occludens-1 (ZO-1), which form intercellular barriers preventing paracellular transport of large molecules. When micro
