How do perivascular cells specifically recognize and respond to amyloid-β to upregulate SPP1 expression?

PARTIALLY ADDRESSED

The abstract indicates SPP1 upregulation occurs in perivascular macrophages and fibroblasts in presence of amyloid-β oligomers, but the sensing mechanisms and signaling pathways that trigger this response are not explained. This gap limits understanding of early disease triggers and potential intervention points. Gap type: unexplained_observation Source paper: Perivascular cells induce microglial phagocytic states and synaptic engulfment via SPP1 in mouse models of Alzheimer's disease.
