Apple Procyanidins Suppress Amyloid β-Protein Aggregation
Procyanidins (PCs) are major components of the apple polyphenols (APs). We previously reported that treatment with PC extended the mean lifespan of Caenorhabditis elegans (Sunagawa et al., 2011). In order to estimate the neuroprotective effects of PC, we investigated the antiaggregative activity of PC on amyloid β-protein (Aβ) aggregation, which is a pathological hallmark of Alzheimer's disease...
متن کاملProteolytic degradation of amyloid β-protein.
The amyloid β-protein (Aβ) is subject to proteolytic degradation by a diverse array of peptidases and proteinases, known collectively as Aβ-degrading proteases (AβDPs). A growing number of AβDPs have been identified, which, under physiological and/or pathophysiological conditions, contribute significantly to the determination of endogenous cerebral Aβ levels. Despite more than a decade of inves...
متن کاملHeterogeneous Association of Alzheimer’s Disease-Linked Amyloid-β and Amyloid-β Protein Precursor with Synapses
Alzheimer's disease (AD) is increasingly viewed as a disease of synapses. Loss of synapses correlates better with cognitive decline than amyloid plaques and neurofibrillary tangles, the hallmark neuropathological lesions of AD. Soluble forms of amyloid-β (Aβ) have emerged as mediators of synapse dysfunction. Aβ binds to, accumulates, and aggregates in synapses. However, the anatomical and neuro...
متن کاملThe Components of Flemingia macrophylla Attenuate Amyloid β-Protein Accumulation by Regulating Amyloid β-Protein Metabolic Pathway
Flemingia macrophylla (Leguminosae) is a popular traditional remedy used in Taiwan as anti-inflammatory, promoting blood circulation and antidiabetes agent. Recent study also suggested its neuroprotective activity against Alzheimer's disease. Therefore, the effects of F. macrophylla on Aβ production and degradation were studied. The effect of F. macrophylla on Aβ metabolism was detected using t...
متن کاملThe impact of a novel apolipoprotein E and amyloid-β protein precursor-interacting protein on the production of amyloid-β.
Alzheimer's disease (AD) is characterized by disrupted metabolism of the amyloid-β protein precursor (AβPP) and deposition of a byproduct, the amyloid-β (Aβ) peptide, into plaques. AD is also genetically linked to the gene for apolipoprotein E (apoE). We have identified a novel apoE-binding protein (TMCC2) that also forms a complex with AβPP. TMCC2 is a neuronal, predominantly ER-localized, pro...
