C1Q/C3 complement activation mediates the intersection of OxPC accumulation and synaptic loss. When microglia successfully neutralize OxPC via TREM2-APOE-ABCA1 axis, complement activation is suppressed and synapses are preserved. In aged microglia with impaired neutralization, OxPC drives C1Q secretion and C3 generation, opsonizing synapses for microglial phagocytosis via C3aR1.

# 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
