c-Abl (ABL1) phosphorylates α-synuclein at Y39, promoting aggregation and neuronal toxicity. Nilotinib (FDA-approved for CML) inhibits c-Abl and promotes α-syn clearance via autophagy, representing a rapid translational candidate. However, the hypothesis faces significant challenges: (1) Y39 phosphorylation is less abundant than S129 in human synucleinopathies and its aggregation role is contested; (2) Nilotinib failed its primary endpoint in PD clinical trials (Ko et al. 2020) with no UPDRS imp
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. The T
