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-Dependent Astrocyte-Microglia Cross-talk in Neuroinflammation proposes that TREM2 dysfunction disrupts critical intercellular communication networks between microglia and astrocytes, leading to pathological neuroinflammation in neurodegenerative diseases. Under normal conditions, TREM2 signaling in microglia promotes the release of anti-inflammatory mediators including IL-10, TGF-β, and specialized pro-resolving mediators (SPMs) that maintain astrocytes in a homeostatic A2-like state.
