The amyloid hypothesis of Alzheimer's disease at 25 years

EMBO Molecular Medicine, 2016
Despite continuing debate about the amyloid β‐protein (or Aβ hypothesis, new lines of evidence from laboratories and clinics worldwide support the concept that an imbalance between production and clearance of Aβ42 and related Aβ peptides is a very early,

Solving the Amyloid Paradox: Unveiling the Complex Pathogenicity of Amyloid Fibrils

Aggregate, EarlyView.
This review addresses the gap between strong evidence for the involvement of amyloid fibrils in neurodegeneration and the failure of anti‐amyloid therapies, a phenomenon herein termed the “amyloid paradox.” To address this paradox, we provide a comprehensive summary of the current understanding of fibrils' pathogenic properties and mechanisms ...

Premenopausal bilateral oophorectomy and Alzheimer's disease imaging biomarkers later in life

Alzheimer's &Dementia, EarlyView.
Abstract INTRODUCTION Premenopausal bilateral oophorectomy (PBO) before the age of 46 years is associated with an increased risk of dementia. We investigated the long‐term effects of PBO performed before age 50 years on amyloid beta (Aβ), tau, and neurodegeneration imaging biomarkers of Alzheimer's disease (AD).

Bleeding is increased in amyloid precursor protein knockout mouse

Research and Practice in Thrombosis and Haemostasis, 2020
Background Amyloid precursor protein (APP) is highly expressed in platelets. APP is the precursor to amyloid beta (Aβ) peptides that accumulate in cerebral amyloid angiopathy and plaques in Alzheimer disease.

Possible roles of amyloid intracellular domain of amyloid precursor protein

BMB Reports, 2010
Amyloid precursor protein (APP), which is critically involved in the pathogenesis of Alzheimer's disease (AD), is cleaved by gamma/epsilon-secretase activity and results in the generation of different lengths of the APP Intracellular C-terminal Domain (AICD).

Autosomal Recessive Cerebellar Ataxias: Translating Genes to Therapies

Annals of Neurology, EarlyView.
Autosomal recessive cerebellar ataxias are disabling neurodegenerative genetic conditions affecting balance and coordination. Advancements in genomic testing have improved diagnosis, leading to a new focus on the development of targeted precision therapeutics addressing cellular, biochemical, and genetic disease mechanisms with a resulting emphasis on ...

Atomic-resolution structures of prion AGAAAAGA amyloid fibrils [PDF]

Published in [Amyloids: Composition, Functions and Pathology, Editors Irene P. Halcheck and Nancy R. Vernon, NOVA Science Publishers, Hauppauge, N.Y., March 1st 2012, ISBN 978-1-62100-538-4, hardcover], Chapter 10, pp.177-186, 2011
To the best of the author's knowledge, there is little structural data available on the AGAAAAGA palindrome in the hydrophobic region (113-120) of prion proteins due to the unstable, noncrystalline and insoluble nature of the amyloid fibril, although many experimental studies have shown that this region has amyloid fibril forming properties and plays ...

Accelerated amyloid deposition, neurofibrillary degeneration and neuronal loss in double mutant APP/tau transgenic mice

Neurobiology of Disease, 2005
Even though the idea that amyloid β peptide accumulation is the primary event in the pathogenesis of Alzheimer's disease has become the leading hypothesis, the causal link between aberrant amyloid precursor protein processing and tau alterations in this ...
