Concise Statement: TDP-43 proteinopathy (as seen in LATE — Limbic-predominant Age-related TDP-43 Encephalopathy) generates a spatially and cellularly distinct epigenetic aging pattern in middle temporal gyrus spiny neurons that is dissociable from canonical AD-associated methylation drift, enabling a clock-based molecular differential diagnosis between LATE, AD, and mixed pathology.
Mechanistic Rationale:
TDP-43 is a major RNA-binding protein and transcriptional repressor whose nuclear clearan
Concise Statement: In Hispanic/Latino adults, the mismatch between chronologically predicted and biologically observed epigenetic aging (the "Hispanic Paradox" analog) reflects a specific pattern of methylation at neuroinflammation-regulatory CpGs that partially decouples amyloid/tau burden from clinical expression of AD — and this decoupling mechanism can be isolated and therapeutically exploited.
Mechanistic Rationale:
The Hispanic Paradox describes paradoxically lower mortality rates in His
