**Molecular Mechanism and Rationale**
The proposed PDGF-BB/PDGFRβ/STAT3 signaling axis represents a complex intercellular communication network that mediates amyloid-β (Aβ)-induced upregulation of secreted phosphoprotein 1 (SPP1) in neurodegeneration. At the molecular level, this mechanism involves a sophisticated cascade initiated by Aβ exposure to cerebrovascular pericytes, which express platelet-derived growth factor receptor β (PDGFRβ) as a defining marker. Upon Aβ binding or exposure, peri
**Molecular Mechanism and Rationale**
The proposed LRP1/NLRP3/IL-1β cascade represents a critical mechanistic link between amyloid-beta (Aβ) oligomer clearance and neuroinflammatory responses in neurodegenerative diseases. Low-density lipoprotein receptor-related protein 1 (LRP1) serves as the primary endocytic receptor responsible for Aβ oligomer uptake in perivascular fibroblasts and brain-resident macrophages. LRP1, a 600-kDa multifunctional receptor, contains four ligand-binding domains tha
