Apolipoprotein (apo) E4 enhances amyloid beta peptide production in cultured neuronal cells: apoE structure as a potential therapeutic target.
Apolipoprotein (apo) E4 is a major risk factor for Alzheimer's disease, and many studies have suggested that apoE has isoform-specific effects on the deposition or clearance of amyloid beta (Abeta) peptides. We examined the effects of apoE isoforms on the processing of amyloid precursor protein (APP) and on Abeta production in rat neuroblastoma B103 cells stably transfected with human wild-type...
متن کاملApolipoprotein E4 potentiates amyloid beta peptide-induced lysosomal leakage and apoptosis in neuronal cells.
We assessed the isoform-specific effects of apolipoprotein (apo) E on the response of Neuro-2a cells to the amyloid beta peptide (Abeta1-42). As determined by the intracellular staining pattern and the release of beta-hexosaminidase into the cytosol, apoE4-transfected cells treated with aggregated Abeta1-42 showed a greater tendency toward lysosomal leakage than neo- or apoE3-transfected cells....
متن کاملApolipoprotein E, especially apolipoprotein E4, increases the oligomerization of amyloid β peptide.
Alzheimer's disease (AD) is the most common progressive neurodegenerative disorder causing dementia. Massive deposition of amyloid β peptide (Aβ) as senile plaques in the brain is the pathological hallmark of AD, but oligomeric, soluble forms of Aβ have been implicated as the synaptotoxic component. The apolipoprotein E ε 4 (apoE ε4) allele is known to be a genetic risk factor for developing AD...

متن کاملApoptosis as a Potential Target in Therapeutic and Vaccine Interventions against Parasitic Diseases
Apoptosis is a physiological cell death that occurs under normal conditions in major biological processes, including the removal of old, damaged, extra, or harmful cells. It plays an important role in natural evolution, tissue homeostasis, removal of cells damaged or infected by viruses, and removal of immune cells activated against self-antigens. The purpose of this review was to examine the r...
