## Mechanistic Overview
P2X7/P2Y12 Purinergic Signaling Connects Aβ Aggregation to SPP1 Transcription via Calcineurin/NFAT Pathway starts from the claim that modulating SPP1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview P2X7/P2Y12 Purinergic Signaling Connects Aβ Aggregation to SPP1 Transcription via Calcineurin/NFAT Pathway starts from the claim that modulating SPP1 within the disease context of
**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
