Molecular programs in human locus coeruleus link APOE and neuromelanin to Alzheimer's vulnerability.
Understanding why brain cells degenerate early in Alzheimer's disease identifies new molecular targets for prevention research before memory loss begins.
This study applies single-cell and bulk transcriptomics to postmortem human locus coeruleus tissue, identifying APOE-driven and neuromelanin-associated molecular programs that explain the selective early degeneration of LC noradrenergic neurons in Alzheimer's disease. The locus coeruleus degenerates before hallmark amyloid/tau pathology, making these molecular programs promising early targets for AD prevention research.

Why it surfaced
Novel molecular mechanism linking APOE risk and neuromelanin in earliest-affected Alzheimer's brain region; opens new targets for pre-symptomatic AD intervention at the LC.
