Perivascular fibroblasts and macrophages clear Aβ oligomers via LRP1, leading to NLRP3 inflammasome activation and IL-1β-dependent SPP1 induction through IL-1R1/MyD88/MAPK signaling. LRP1 has been shown to mediate Aβ clearance across the blood-brain barrier, supporting its role in cellular uptake of oligomeric species (PMCID:28467792). The NLRP3 inflammasome links Aβ accumulation to microglial inflammatory responses (PMCID:29432182), though it is worth noting that NLRP3 inflammasome activation i
# Temporal SPP1 Inhibition During Critical Windows: Mechanistic Framework and Therapeutic Rationale
## Hypothesis Summary
Temporal SPP1 (Secreted Phosphoprotein 1, also known as Osteopontin) neutralization represents a precision-immunology strategy for intercepting neurodegeneration during mechanistically defined disease stages. Rather than continuous suppression of microglial activity, this approach proposes time-restricted blockade of SPP1 signaling through inducible biologics during windows
