Accumulating evidence indicates that loss of physiologic amyloid precursor protein (APP) function leads to reduced neuronal plasticity, diminished synaptic signaling and enhanced susceptibility of neurons to cellular stress during brain aging. Here we investigated the neuroprotective function of the soluble APP ectodomain sAPPα (soluble APPα), which is(More)
Alzheimer's disease (AD) is the major age-associated form of dementia characterized by gradual cognitive decline. Aberrant cleavage of the amyloid-β protein precursor (AβPP) is thought to play an important role in the pathology of this disease. Two principal AβPP processing pathways exist: amyloidogenic cleavage of AβPP resulting in production of the(More)
Maintenance of intracellular proteostasis is essential for neuronal function, and emerging data support the view that disturbed proteostasis plays an important role in brain aging and the pathogenesis of age-related neurodegenerative disorders such as Alzheimer’s disease (AD). sAPPalpha (sAPPα), the extracellularly secreted N-terminal alpha secretase(More)
