Familial Alzheimer's disease mutations differentially alter amyloid β-protein oligomerization.
Although most cases of Alzheimer's disease (AD) are sporadic, ∼5% of cases are genetic in origin. These cases, known as familial Alzheimer's disease (FAD), are caused by mutations that alter the rate of production or the primary structure of the amyloid β-protein (Aβ). Changes in the primary structure of Aβ alter the peptide's assembly and toxic activity. Recently, a primary working hypothesis ...
متن کاملAmino Acid Position-specific Contributions to Amyloid Β- Protein Oligomerization
Understanding the structural and assembly dynamics of the amyloid β-protein (Aβ) has direct relevance to the development of therapeutic agents for Alzheimer's disease. To elucidate these dynamics, we combined scanning amino acid substitution with a method for quantitative determination of the Aβ oligomer frequency distribution, PhotoInduced Cross-linking of Unmodified Proteins (PICUP), to perfo...
متن کامل5-Hydroxycyclopenicillone Inhibits β-Amyloid Oligomerization and Produces Anti-β-Amyloid Neuroprotective Effects In Vitro.
The oligomer of β-amyloid (Aβ) is considered the main neurotoxin in Alzheimer's disease (AD). Therefore, the inhibition of the formation of Aβ oligomer could be a target for AD therapy. In this study, with the help of the dot blotting assay and transmission electronic microscopy, it was have discovered that 5-hydroxycyclopenicillone, a cyclopentenone recently isolated from a sponge-associated f...
متن کاملGM1 Ganglioside Inhibits β‐Amyloid Oligomerization Induced by Sphingomyelin
β-Amyloid (Aβ) oligomers are neurotoxic and implicated in Alzheimer's disease. Neuronal plasma membranes may mediate formation of Aβ oligomers in vivo. Membrane components sphingomyelin and GM1 have been shown to promote aggregation of Aβ; however, these studies were performed under extreme, non-physiological conditions. We demonstrate that physiological levels of GM1 , organized in nanodomains...
متن کاملInhaled Anesthetic Enhancement of Amyloid-β Oligomerization and Cytotoxicity
Background: The majority of surgical patients receive inhaled anesthetics, principally small haloalkanes and haloethers. Long-term cognitive problems occur in the elderly subsequent to anesthesia and surgery, and previous surgery might also be a risk factor for neurodegenerative disorders like Alzheimer and Parkinson disease. The authors hypothesize that inhaled anesthetics contribute to these ...
