Identification of a TREM2-independent disease-associated microglial (DAM) trajectory in late-stage AD. Single-cell analysis reveals microglial subclusters expressing elevated APOE, CSF1R, and CX3CR1 without TREM2 activation markers, suggesting an alternative activation pathway driving neuroinflammation through C3 upregulation.
Pericyte-endothelial cross-talk failure leads to MMP9-mediated BBB disruption and tau propagation. Single-nucleus data reveals pericytes downregulate PDGFRB and CLDN5, while endothelial cells lose TJP1 (ZO-1) expression, correlating with elevated MMP9 in neutrophils and microglia.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
