Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2.

, 2012
BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

Advanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Melatonin-mediated calcineurin inactivation attenuates amyloid beta-induced apoptosis

IBRO Neuroscience Reports
Alzheimer’s disease (AD) is the most common age-related progressive neurodegenerative disorder. The accumulation of amyloid beta-peptide is a neuropathological marker of AD.

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 ...

Amyloid-Beta: A Crucial Factor in Alzheimer's Disease

Medical Principles and Practice, 2014
Alzheimer's disease (AD) is the most prevalent form of dementia which affects people older than 60 years of age. In AD, the dysregulation of the amyloid-beta (Aβ) level leads to the appearance of senile plaques which contain Aβ depositions.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Passive Aβ Immunotherapy: Current Achievements and Future Perspectives

Molecules, 2018
Passive immunotherapy has emerged as a very promising approach for the treatment of Alzheimer’s disease and other neurodegenerative disorders, which are characterized by the misfolding and deposition of amyloid peptides. On the basis of the amyloid

Truncated and modified amyloid-beta species

Alzheimer's Research & Therapy, 2014
Alzheimer’s disease pathology is closely connected to the processing of the amyloid precursor protein (APP) resulting in the formation of a variety of amyloid-beta (Aβ) peptides.

The copper-amyloid-beta-peptide complex of Alzheimer’s disease: affinity, structure, fibril formation and toxicity

, 2010
PhDSenile plaques of Alzheimer’s disease (AD) patients are composed primarily of the amyloid-β-peptide peptide (Aβ), and within these plaques Cu2+ ions are found concentrated and directly bound to Aβ.

A novel amyloid designable scaffold and potential inhibitor inspired by GAIIG of amyloid beta and the HIV-1 V3 loop.

, 2018
The GAIIG sequence, common to the amyloid beta peptide (residues 29-33) and to the HIV-1 gp120 (residues 24-28 in a typical V3 loop), self-assembles into amyloid fibrils, as suggested by theory and the experiments presented here.
