PINK1/PARKIN-mediated mitophagy is impaired in sporadic PD due to upstream mitochondrial stress. Enhancing parkin translocation or inhibiting USP30 (deubiquitinase opposing mitophagy) can restore clearance of damaged mitochondria. This hypothesis extrapolates from familial PD (PINK1/PARKIN mutations) to sporadic disease without direct evidence of shared mechanism. USP30 inhibitors showed promising preclinical neuroprotection but have not translated to clinical success. The fundamental problem is
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
