Concise Statement: Progressive failure of autophagy flux in AD neurons produces a cascading epigenetic feedback loop — as autophagy declines, damaged organelles accumulate, generating ROS-driven methylation drift at autophagy regulatory genes, which further suppresses autophagy in a self-reinforcing cycle that is quantifiable as a disease-stage-specific methylation "chronometer."
Mechanistic Rationale:
Autophagy is essential for clearance of amyloid precursors, tau oligomers, and dysfunctional
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
