متن کاملESCRTs regulate amyloid precursor protein sorting in multivesicular bodies and intracellular beta amyloid accumulation
Intracellular beta amyloid (Aβ) accumulation is a key feature of early Alzheimer’s disease (AD) and precedes the appearance of Aβ in extracellular plaques. Aβ is generated through proteolytic processing of amyloid precursor protein (APP), but the intracellular site of Aβ production is unclear. APP has been localized to multivesicular endosomes/bodies (MVBs) where sorting of APP onto ILVs could ...
متن کاملPossible roles of amyloid intracellular domain of amyloid precursor protein.
Amyloid precursor protein (APP), which is critically involved in the pathogenesis of Alzheimer's disease (AD), is cleaved by gamma/epsilon-secretase activity and results in the generation of different lengths of the APP Intracellular C-terminal Domain (AICD). In spite of its small size and short half-life, AICD has become the focus of studies on AD pathogenesis. Recently, it was demonstrated th...
متن کاملDestruxin E decreases Beta-amyloid generation by reducing colocalization of beta-amyloid-cleaving enzyme 1 and beta-amyloid protein precursor.
Alzheimer-disease-associated beta-amyloid (Abeta) is produced by sequential endoproteolysis of beta-amyloid protein precursor (betaAPP): the extracellular portion is shed by cleavage in the juxtamembrane region by beta-amyloid-cleaving enzyme (BACE)/beta-secretase, after which it is cleaved by presenilin (PS)/gamma-secretase near the middle of the transmembrane domain. Thus, inhibition of eithe...
متن کاملSorLA is a molecular link for retromer-dependent sorting of the Amyloid precursor protein
Deficiency in the retromer sorting pathway is known to be associated with the onset of Alzheimer disease (AD), and has been suggested to involve regulation of Amyloid precursor protein (APP) trafficking. Absence of the APP sorting receptor sorLA is also associated to AD, as amyloidogenic processing of APP is increased due to missorting. Reduced activity of either retromer or sorLA thus both lea...
