Top Hypotheses (2 total)
#1 TREM2-SYK Signaling Axis Couples OxPC Recognition to Phagocytic Clearance
0.505
TREM2 (Triggering receptor expressed on myeloid cells 2) + SYK (spleen tyrosine kinase)
TREM2 agonism restores age-impaired SYK signaling for OxPC clearance. Upon OxPC exposure, TREM2 engagement activates TYROBP (DAP12)-mediated SYK recruitment, driving phosphoinositide signaling require
#2 Complement Cascade Activation Bridges Microglial OxPC Sensing to Synaptic Vulnerability
0.452
C1QA, C3, C3AR1 (complement cascade)
C1Q/C3 complement activation mediates the intersection of OxPC accumulation and synaptic loss. When microglia successfully neutralize OxPC via TREM2-APOE-ABCA1 axis, complement activation is suppresse
