Int J Clin Exp Pathol. 2009;2(4):339-52. Epub 2008 Nov 26.

Alzheimer's disease (AD) is a leading cause of chronic dementia in the United States. Its incidence is increasing with an attendant increase in associated health care costs. Amyloid beta peptide (Abeta; a 39-42 amino acid molecule) is the major...

Amyloid-beta protein precursor (APP) and metabolite levels are altered in fragile X syndrome (FXS) patients and in the mouse model of the disorder,

PAMP and PARL, two novel putative metalloproteases interacting with the COOH-terminus of Presenilin-1 and -2.

Journal of Alzheimer's disease : JAD

Pellegrini L, Passer BJ, Canelles M, Lefterov I, Ganjei JK, Fowlkes BJ, Koonin EV, D'Adamio L.
PMID: 12214059
J Alzheimers Dis. 2001 Apr;3(2):181-190. doi: 10.3233/jad-2001-3203.

The familial Alzheimer's disease gene products, presenilin-1 and presenilin-2 (PS1 and PS2), are involved in amyloid beta-protein precursor processing (AbetaPP), Notch receptor signaling, and programmed cell death. However, the molecular mechanisms by which presenilins regulate these processes remain unknown....

Tau Pathology of Alzheimer Disease: Possible Role of Sleep Deprivation.

Basic and clinical neuroscience

Sleep deprivation is a common complaint in modern societies. Insufficient sleep has increased the risk of catching neurodegenerative diseases such as Alzheimer's. Several studies have indicated that restricted sleep increases the level of deposition of β-amyloid and formation of...

Chronic Leptin Supplementation Ameliorates Pathology and Improves Cognitive Performance in a Transgenic Mouse Model of Alzheimer's Disease.

We have previously reported anti-amyloidogenic effects of leptin using in vitro and in vivo models and, more recently, demonstrated the ability of leptin to reduce tau phosphorylation in neuronal cells. The present study examined the efficacy of leptin in...

Abetapp secretases are co-expressed with Abetapp in the pancreatic islets.

Amyloid beta protein precursor is cleaved by beta- and gamma-secretases to produce Abeta peptides which deposit in amyloid plaques in Alzheimer's disease (AD) brain. A recently identified beta-site cleaving enzyme (BACE) appears to fulfill the requirements for beta-secretase, and...

Abeta immunoreactive material is present in several intracellular compartments in transfected, neuronally differentiated, P19 cells expressing the human amyloid beta-protein precursor.

J Alzheimers Dis. 2000 Nov;2(3):207-22. doi: 10.3233/jad-2000-23-403.

Processing of the amyloid beta-protein precursor is believed to play a critical role in the development of Alzheimer's disease neuropathology. The localization of the human Abeta epitope within mature neuroectodermally differentiated embryonal carcinoma (P19) cells, stably transfected with the...

Using the zebrafish model for Alzheimer's disease research.

Rodent models have been extensively used to investigate the cause and mechanisms behind Alzheimer's disease. Despite many years of intensive research using these models we still lack a detailed understanding of the molecular events that lead to neurodegeneration. Although...

Inter-Dependent Mechanisms Behind Cognitive Dysfunction, Vascular Biology and Alzheimer's Dementia in Down Syndrome: Multi-Faceted Roles of APP.

People with Down syndrome (DS) virtually all develop intellectual disability (ID) of varying degree of severity, and also have a high risk of early Alzheimer's disease (AD). ID prior to the onset of dementia, and its relationship to the...

Generation of an apoptotic intracellular peptide by gamma-secretase cleavage of Alzheimer's amyloid beta protein precursor.

The amyloid beta protein precursor (AbetaPP) is sequentially processed by beta- and gamma-secretases to generate the Abeta peptide. The biochemical path leading to Abeta formation has been extensively studied since extracellular aggregates of amyloidogenic forms of Abeta peptide (Abeta42)...
