Amyloid-beta peptide and tau protein crosstalk in Alzheimer’s disease

open access: yesNeural Regeneration Research, 2022
Alzheimer’s disease is a neurodegenerative disease that accounts for most of the 50-million dementia cases worldwide in 2018. A large amount of evidence supports the amyloid cascade hypothesis, which states that amyloid-beta accumulation triggers tau ...

Decreased Deposition of Beta-Amyloid 1-38 and Increased Deposition of Beta-Amyloid 1-42 in Brain Tissue of Presenilin-1 E280A Familial Alzheimer’s Disease Patients

open access: yesFrontiers in Aging Neuroscience, 2020
Familial Alzheimer’s Disease (FAD) caused by Presenilin-1 (PS1) mutations is characterized by early onset, cognitive impairment, and dementia. Impaired gamma secretase function favors production of longer beta-amyloid species in PS1 FAD.

Cognitive and brain cytokine profile of non-demented individuals with cerebral amyloid-beta deposition

open access: yesJournal of Neuroinflammation, 2021
Background Brain inflammation has been increasingly associated with early amyloid accumulation in Alzheimer’s disease models; however, evidence of its occurrence in humans remains scarce.

Beta-amyloid imaging with florbetaben [PDF]

open access: yesClinical and Translational Imaging, 2015
Florbetaben is a fluorine-18 (18F)-labeled stilbene derivative that was developed as a positron emission tomography (PET) tracer for routine clinical application to visualize β-amyloid plaques in the Alzheimer's disease (AD) brain. The tracer successfully completed a global multicenter phase 0-III development program and was, as a consequence, recently

Lowering beta-amyloid levels rescues learning and memory in a Down syndrome mouse model. [PDF]

open access: yesPLoS ONE, 2010
beta-amyloid levels are elevated in Down syndrome (DS) patients throughout life and are believed to cause Alzheimer's disease (AD) in adult members of this population.

Beta amyloid deposition and cognitive decline in Parkinson’s disease: a study of the PPMI cohort

open access: yesMolecular Brain, 2022
The accumulation of beta amyloid in the brain has a complex and poorly understood impact on the progression of Parkinson’s disease pathology and much controversy remains regarding its role, specifically in cognitive decline symptoms.

Small-angle X-ray scattering characterization of a $$\beta $$ β -amyloid model in phantoms

open access: yesBMC Research Notes, 2020
Objective We present a method to prepare an amyloid model at scalable quantities for phantom studies to evaluate small-angle x-ray scattering systems for amyloid detection. Two amyloid models were made from a plasma protein with and without heating. Both

The Roles of the Amyloid Beta Monomers in Physiological and Pathological Conditions

open access: yesBiomedicines, 2023
Amyloid beta peptide is an important biomarker in Alzheimer’s disease, with the amyloidogenic hypothesis as one of the central hypotheses trying to explain this type of dementia.

Neurotoxicity of .BETA.-amyloid.

open access: yesFolia Pharmacologica Japonica, 2000
Recent observations on the neurotoxicity of beta-amyloid have been reviewed and possible roles of racemization of beta-amyloid are discussed. beta 1-40, beta 25-35 and D-Ser26 beta 25-35 (all HCl salt forms), but not commercially available beta 1-40 (TFA salt form), take the beta-structure within few hours in PBS, form fibrils, exert toxic effects on ...

Synapses, synaptic activity and intraneuronal Aβ in Alzheimer's disease

open access: yesFrontiers in Aging Neuroscience, 2010
β-amyloid peptide accumulation plays a central role in the pathogenesis of Alzheimer’s disease. Aberrant β-amyloid buildup in the brain has been shown to be present both in the extracellular space and within neurons.
