Age-dependent brain pigmentation drives early neuroinflammatory molecular signatures linked to neurodegeneration

Abstract

BackgroundNeuromelanin (NM) is a pigment that progressively accumulates with age in catecholaminergic neurons, particularly in the substantia nigra, ventral tegmental area, and locus coeruleus. These neuronal populations are especially vulnerable to degeneration in Parkinsons disease (PD).
