Our data identify a distinct senescence response and provide a mechanism by which mitochondrial dysfunction can drive aging phenotypes.

Enhanced amyloidogenic processing of APP by the ß - site APP cleaving enzyme (BACE) and the γ - secretase complex and reduced clearance lead to increased intracellular levels of soluble oligomeric Aß, resulting in cellular dysfunction comprising e.g., synaptic failure, mitochondrial dysfunction, enhanced oxidative stress, neurotransmitter and neurotrophin depletion, inflammation, and apoptosis which is reflected in patients as clinical symptoms such as cognitive deficits [2, 3].
