Journal ArticleDOI
The polyphenol oleuropein aglycone protects TgCRND8 mice against Aß plaque pathology.
Cristina Grossi,Stefania Rigacci,Stefano Ambrosini,Teresa Ed Dami,Ilaria Luccarini,Chiara Traini,Paola Failli,Andrea Berti,Fiorella Casamenti,Massimo Stefani +9 more
TL;DR: Dietary supplementation of oleuropein aglycone strongly improves the cognitive performance of young/middle-aged TgCRND8 mice, a model of amyloid-ß deposition, respect to age-matched littermates with un-supplemented diet, and mechanistic insights into the beneficial effects against Alzheimer-associated neurodegeneration of a polyphenol enriched in the extra virgin olive oil are provided.
Journal ArticleDOI
Nutraceutical Properties of Olive Oil Polyphenols. An Itinerary from Cultured Cells through Animal Models to Humans.
Stefania Rigacci,Massimo Stefani +1 more
TL;DR: This review travels through most of the current and past research, recapitulating the biochemical and physiological correlations of the beneficial properties of olive tree (Olea europaea) polyphenols and their derivatives found in olive oil.
Journal ArticleDOI
Protein folding and aggregation into amyloid: the interference by natural phenolic compounds.
Massimo Stefani,Stefania Rigacci +1 more
TL;DR: The significance and mechanisms of amyloid aggregation and aggregate toxicity are overviewed, and the recent achievements on protection against amyloids diseases by many natural phenols are summarized.
Journal ArticleDOI
Oleuropein aglycone protects transgenic C. elegans strains expressing Aβ42 by reducing plaque load and motor deficit.
TL;DR: The ability of OLE to interfere with Aβ proteotoxicity in vivo is evaluated by using the transgenic CL2006 and CL4176 strains of Caenorhabditis elegans, simplified models of AD and of sIBM, which express human Aβ in the cytoplasm of body wall muscle cells.
Journal ArticleDOI
Aβ(1-42) aggregates into non-toxic amyloid assemblies in the presence of the natural polyphenol oleuropein aglycon.
Stefania Rigacci,Valentina Guidotti,Monica Bucciantini,Daniela Nichino,Annalisa Relini,Andrea Berti,Massimo Stefani +6 more
TL;DR: It is reported that the polyphenol eliminates the appearance of early toxic oligomers favouring the formation of stable harmless protofibrils, structurally different from the typical Aβ(1-42) fibrils.
