The novel amyloid-beta peptide aptamer inhibits intracellular amyloid-beta peptide toxicity
Amyloid β peptide binding alcohol dehydrogenase (ABAD) decoy peptide (DP) can competitively antagonize binding of amyloid β peptide to ABAD and inhibit the cytotoxic effects of amyloid β peptide. Based on peptide aptamers, the present study inserted ABAD-DP into the disulfide bond of human thioredoxin (TRX) using molecular cloning technique to ...

Characterizing Heparin Tetrasaccharides Binding to Amyloid-Beta Peptide [PDF]
The aggregation of β-amyloid peptide (Aβ) is one potential cause for Alzheimer’s disease (AD). Heparin can either promote or inhibit Aβ aggregation. The sulfation pattern and chain size determine its binding affinity and its role. Using 2D-NMR analysis and molecular modelling, the binding motif of heparin oligoaccharides to Aβ was determined to be HexA-

Mechanisms of amyloid-β34 generation indicate a pivotal role for BACE1 in amyloid homeostasis
The beta‑site amyloid precursor protein (APP) cleaving enzyme (BACE1) was discovered due to its “amyloidogenic” activity which contributes to the production of amyloid-beta (Aβ) peptides. However, BACE1 also possesses an “amyloidolytic” activity, whereby

Cerebrospinal Fluid Tau, p-Tau 181 and Amyloid-beta(38/40/42) in Frontotemporal Dementias and Primary Progressive Aphasias [PDF]
Background/Aims: We determined cerebrospinal fluid (CSF) concentrations of amyloid-beta(A beta)(1-38), A beta(1-40), A beta(1-42), total tau and phospho-tau (p-tau) in order to study their differential expression in frontotemporal dementia (FTD, n = 25 ...

Amyloid-.BETA. peptide metabolism and Alzheimer's disease
The deposition of amyloid-beta peptide (Abeta) causes the long-term pathological cascade of Alzheimer's disease (AD). Neprilysin is a rate-limiting peptidase, which participates in Abeta degradation in brain. As demonstrated by reverse genetics, the disruption of neprilysin gene causes an elevation in endogenous Abeta levels in the mouse brain in a ...

Effects of Amyloid Beta Peptide on Neurovascular Cells
Alzheimer’s disease (AD) is a chronic neurodegenerative disorder, which is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in specific regions of the brain, accompanied by impairment of the neurons, and progressive deterioration of cognition and memory of affected individuals.
