**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
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
