Senescent microglia expressing p16^Ink4a and p21^Cip1/Waf1 constitute the cellular substrate driving persistent neuroinflammation months after pediatric TBI. These cells secrete SASP factors including IL-1β, IL-6, and CXCL8, which amplify complement C1Q/C3 deposition on synapses. Intermittent dasatinib+quercetin (D+Q) senolytic therapy initiated 1-month post-injury ablates these cells, breaking the SASP-complement amplification loop.

# 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
