Autophagy Dysfunction

Autophagy Dysfunction enters the Adult Cognitive Disease corpus through the submissions of Erwin Roggen (submission 56) and Carina Clawson (submission 90), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Erwin Roggen's submission is summarised in this corpus as:

Sporadic Alzheimer's disease is a toxicological outcome of cumulative environmental and metabolic insults, mapped through a Tau-Driven Adverse Outcome Pathway (AOP) framework. Twenty-seven environmental neurotoxicants converge on molecular initiating events -- primarily mitochondrial dysfunction and metabolic dysregulation -- cascading through oxidative stress, tau hyperphosphorylation, and dysfunctional autophagy.

The source paper puts the concept to work directly:

The production of cytosolic toxic Tau variants seems to be driven by MIEs resulting in autophagy dysfunction (KE4). Other MIEs may also have direct effects on synaptic function and plug into KEs that are already mentioned in the OECD AOP database, e.g.

The argument it belongs to

Carina Clawson's submission is summarised in this corpus as:

Alzheimer's disease is a 'disease of chronic accumulations' where no single feature is sufficient; instead, protein aggregation, lipid imbalance (particularly ceramide dysregulation), mitochondrial dysfunction, and oxidative stress create positive feedback loops that overwhelm neuronal compensatory mechanisms. A dual trigger model -- one immunologic and one metabolic -- initiates the cascade.
