Alzheimer’s disease (AD) is characterized by cerebral deposition of β-amyloid (Aβ) peptides, which are generated from amyloid precursor protein (APP) by β- and γ-secretases. APP and the secretases are membrane associated, but whether membrane trafficking

Amyloid Precursor Proteins Are Dynamically Trafficked and Processed during Neuronal Development [PDF]
Proteolytic processing of the Amyloid Precursor Protein (APP) produces beta-amyloid (Aβ) peptide fragments that accumulate in Alzheimer’s Disease (AD), but APP may also regulate multiple aspects of neuronal development, albeit via mechanisms that are not

The competitive ectodomain shedding of amyloid-β precursor protein (APP) by α-secretase and β-secretase, and the subsequent regulated intramembrane proteolysis by γ-secretase are the key processes in amyloid-β peptides (Aβ) generation.

Intracellular pH regulates amyloid precursor protein intracellular domain accumulation
The amyloid precursor protein (APP) metabolism is central to pathogenesis of Alzheimer’s disease (AD). Parenchymal amyloid deposits, a neuropathological hallmark of AD, are composed of amyloid-beta peptides (Abeta).

Hypoxic regulation of ion channel function and expression [PDF]
Acute hypoxia regulates the activity of specific ion channels in a rapid and reversible manner. Such effects underlie appropriate cellular responses to hypoxia which are designed to initiate cardiorespiratory reflexes and contribute importantly to other ...

Upregulation of APP, ADAM10 and ADAM17 in the denervated mouse dentate gyrus. [PDF]
The disintegrin and metalloproteinases ADAM10 and ADAM17 are regarded as the most important α-secretases involved in the physiological processing of amyloid precursor protein (APP) in brain.

Alzheimer’s Disease: A Molecular View of β-Amyloid Induced Morbific Events
Amyloid-β (Aβ) is a dynamic peptide of Alzheimer’s disease (AD) which accelerates the disease progression. At the cell membrane and cell compartments, the amyloid precursor protein (APP) undergoes amyloidogenic cleavage by β- and γ-secretases and ...

Why are Functional Amyloids Non-Toxic in Humans? [PDF]
Amyloids were first identified in association with amyloidoses, human diseases in which proteins and peptides misfold into amyloid fibrils. Subsequent studies have identified an array of functional amyloid fibrils that perform physiological roles in ...

Apolipoprotein E modulates γ‐secretase cleavage of the amyloid precursor protein [PDF]
AbstractPolymorphisms in the apolipoprotein E (APOE) gene affect the risk of Alzheimer disease and the amount of amyloid β‐protein (Aβ) deposited in the brain. The apoE protein reduces Aβ levels in conditioned media from cells in culture, possibly through Aβ clearance mechanisms.
