🧪 Overview
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.

🔮 Falsifiable Predictions (2)
pendingconf 60%
IF pharmacologic CSF1R inhibition (PLX3397 or BLZ945, 100mg/kg daily for 4-8 weeks) is administered in a late-stage AD mouse model (5xFAD at 9 months), THEN C3 expression in isolated CD11b+ microglial cells will decrease by ≥50% compared to vehicle-treated controls, as measured by qPCR and ELISA.
Predicted outcome: ≥50% reduction in microglial C3 mRNA and protein levels following CSF1R blockade in late-stage AD
Falsification: No significant change or increase in C3 expression after CSF1R inhibition, indicating the pathway operates independently of CSF1R signaling
pendingconf 55%
IF TREM2 is genetically knocked out in 5xFAD mice (crossed with Trem2-/-), THEN single-cell RNA sequencing at 9 months will reveal a microglial subcluster expressing elevated APOE, CSF1R, and CX3CR1 (log2FC ≥1.5 vs. wildtype), indistinguishable from the TREM2-independent trajectory observed in human
Predicted outcome: Identical DAM subcluster with high APOE, CSF1R, CX3CR1 and low TREM2 activation markers in TREM2 knockout AD mice
Falsification: Absence of APOE/CSF1R/CX3CR1 co-expressing microglial subcluster in Trem2-/- 5xFAD mice; or presence of this cluster only in TREM2-intact animals, disproving TREM2-independence
