# 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
Reactive astrocytes, rather than microglia, represent the primary pathogenic source of SPP1 in neuroinflammation through STAT3-dependent transcriptional upregulation. Under neuroinflammatory conditions, astrocytes transition from a homeostatic to reactive state characterized by massive SPP1 overproduction that drives aberrant microglial recruitment and sustains chronic inflammation. This astrocyte-centric SPP1 signaling operates through a distinct mechanism involving JAK2/STAT3 pathway activatio
