Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]
, 2009 The cause(s) of sporadic Alzheimer's disease (sAD) are complex and currently poorly understood. They likely result from a combination of genetic, environmental, proteomic and lipidomic factors that crucially occur only in the aged brain.

The novel amyloid-beta peptide aptamer inhibits intracellular amyloid-beta peptide toxicity
Neural Regeneration Research, 2013 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 ...

Mechanisms of amyloid-β34 generation indicate a pivotal role for BACE1 in amyloid homeostasis
Scientific Reports, 2023 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

Naturally occurring autoantibodies against beta-amyloid: investigating their role in transgenic animal and in vitro models of Alzheimer's disease [PDF]
, 2011 Alzheimer's disease (AD) is a neurodegenerative disorder primarily affecting regions of the brain responsible for higher cognitive functions. Immunization against β-amyloid (Aβ) in animal models of AD has been shown to be effective on the molecular level

d-Amino Acid Pseudopeptides as Potential Amyloid-Beta Aggregation Inhibitors
Molecules, 2018 A causative factor for neurotoxicity associated with Alzheimer’s disease is the aggregation of the amyloid-β (Aβ) peptide into soluble oligomers.

Amyloid-.BETA. peptide metabolism and Alzheimer's disease
Folia Pharmacologica Japonica, 2003 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 ...

Passive Aβ Immunotherapy: Current Achievements and Future Perspectives
Molecules, 2018 Passive immunotherapy has emerged as a very promising approach for the treatment of Alzheimer’s disease and other neurodegenerative disorders, which are characterized by the misfolding and deposition of amyloid peptides. On the basis of the amyloid
