All‐Amyloid Functional Coacervates

Advanced Materials, EarlyView.
This study introduces an all‐amyloid interfacial complex coacervate technique that employs charge‐mediated or functionalization‐assisted complexation of oppositely charged food protein‐derived amyloid nanofibrils to engineer functional soft constructs across multiple length scales.

Oligomers mediate the spatial transmission of Aβ peptide aggregation

Communications Chemistry
Alzheimer’s disease (AD) is marked by the abnormal aggregation of amyloid-beta peptides within the central nervous system. The formation of amyloid fibrils from amyloid-beta peptides is a hallmark of AD Here, we demonstrate that the aggregation of ...

Information-Selectivity of Beta-Amyloid Pathology in an Associative Memory Model

Frontiers in Computational Neuroscience, 2012
This work updates Ruppin and Reggia's associative neural network model of Alzheimer's disease by simulating beta-amyloid pathology and modelling the progression of beta-amyloid throughout the network according to Small's synaptic scaling theory, leading ...

Systematic analysis of nucleation-dependent polymerization reveals new insights into the mechanism of amyloid self-assembly [PDF]

, 2008
Self-assembly of misfolded proteins into ordered fibrillar aggregates known as amyloid results in numerous human diseases. Despite an increasing number of proteins and peptide fragments being recognised as amyloidogenic, how these amyloid aggregates ...

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

β-microglobulin amyloid fibril-induced membrane disruption is enhanced by endosomal lipids and acidic pH [PDF]

, 2014
Although the molecular mechanisms underlying the pathology of amyloidoses are not well understood, the interaction between amyloid proteins and cell membranes is thought to play a role in several amyloid diseases. Amyloid fibrils of β-microglobulin (βm),

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Activation of autophagy by Citri Reticulatae Semen extract ameliorates amyloid-beta-induced cell death and cognition deficits in Alzheimer’s disease

Neural Regeneration Research
Amyloid-beta-induced neuronal cell death contributes to cognitive decline in Alzheimer’s disease. Citri Reticulatae Semen has diverse beneficial effects on neurodegenerative diseases, including Parkinson’s and Huntington’s diseases, however, the effect ...

Amyloid and tau in the brain in sporadic Alzheimer’s disease: defining the chicken and the egg [PDF]

, 2014
In the October 2013 issue of Acta Neuropathologica there were three very interesting articles on: Amyloid or tau: the chicken or the egg? In the first article, David Mann and John Hardy argued that the deposition of aggregated amyloid β (Aβ) protein in ...
