Blood-brain barrier breakdown allows peripheral immune cells to infiltrate the CNS, exacerbating neuroinflammation and synaptic damage in AD. GAS6-activated TAM receptors (particularly AXL and MERTK) maintain BBB integrity by promoting tight junction protein expression and suppressing matrix metalloproteinase activity, preventing harmful leukocyte extravasation.
# 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
