Destruxin E Decreases Beta-Amyloid Generation by Reducing Colocalization of Beta-Amyloid-Cleaving Enzyme 1 and Beta-Amyloid Protein Precursor [PDF]

open access: yesNeurodegenerative Diseases, 2009
Alzheimer-disease-associated β-amyloid (Aβ) is produced by sequential endoproteolysis of β-amyloid protein precursor (βAPP): the extracellular portion is shed by cleavage in the juxtamembrane region by β-amyloid-cleaving enzyme (BACE)/β-secretase, after which it is cleaved by presenilin (PS)/γ-secretase near the middle of the transmembrane domain. Thus,

Zinc metalloproteinases and amyloid Beta-Peptide metabolism : the positive side of proteolysis in Alzheimer's disease [PDF]

open access: yes, 2011
Alzheimer's disease is a neurodegenerative condition characterized by an accumulation of toxic amyloid beta- (Aβ-)peptides in the brain causing progressive neuronal death.

Structural Studies of Cystatin B Amyloid Fibre and Oligomer [PDF]

open access: yes, 2013
Amyloid fibres are characteristic of over 25 degenerative human diseases including Alzheimer’s and Parkinson’s disease. Amyloid fibres are insoluble, highly stable, ordered cross-β sheet structures, which form as a result of conformational change and ...

The copper-amyloid-beta-peptide complex of Alzheimer’s disease: affinity, structure, fibril formation and toxicity [PDF]

open access: yes, 2010
PhDSenile plaques of Alzheimer’s disease (AD) patients are composed primarily of the amyloid-β-peptide peptide (Aβ), and within these plaques Cu2+ ions are found concentrated and directly bound to Aβ.

Regulation of the metabolism of the Alzheimer's amyloid precursor protein by contactin 5 and BIN1 [PDF]

open access: yes, 2012
Alzheimer’s disease (AD) is a progressive form of dementia, which currently has no cure. The metabolism of the amyloid precursor protein (APP) is an important determinant in the development of AD.

Mitochondrial β-amyloid in Alzheimer's disease [PDF]

open access: yes, 2011
This research is supported by Alzheimer's Research UK, the Wellcome Trust and the Biotechnology and Biological Sciences Research Council.It is well established that the intracellular accumulation of beta-amyloid is associated with Alzheimer’s disease and

Ectodomain shedding of the amyloid precursor protein: Cellular control mechanisms and novel modifiers [PDF]

open access: yes, 2006
Proteolytic cleavage in the ectodomain of the amyloid precursor protein (APP) is a key regulatory step in the generation of the Alzheimer's disease amyloid-beta (A beta) pepticle and occurs through two different protease activities termed alpha- and beta-

Acyl peptide hydrolase degrades monomeric and oligomeric amyloid-beta peptide

open access: yesMolecular Neurodegeneration, 2009
Background The abnormal accumulation of amyloid-beta peptide is believed to cause malfunctioning of neurons in the Alzheimer's disease brain. Amyloid-beta exists in different assembly forms in the aging mammalian brain including monomers, oligomers, and ...
