Lipocalin-2 (LCN2), secreted by reactive astrocytes, binds to astrocytic LCN2R and triggers iron-dependent ferroptosis of neighboring synapses. LCN2 elevation correlates with cognitive decline independent of amyloid burden, offering an amyloid-independent mechanism. However, the hypothesis suffers from multiple fundamental weaknesses: (1) LCN2R remains poorly characterized with questionable specificity; (2) no GWAS support for LCN2 or related iron metabolism genes in AD risk; (3) ferroptosis evi
TREM2 signaling in microglia regulates oligodendrocyte survival and myelin maintenance through a specialized metabolic support mechanism that becomes dysregulated in white matter neurodegeneration. Upon recognition of myelin debris and damaged oligodendrocytes, TREM2-activated microglia undergo a metabolic shift toward aerobic glycolysis, producing high levels of lactate, pyruvate, and ketone bodies that serve as essential energy substrates for oligodendrocytes during demyelinating stress.
