Longitudinal Association of Amyloid Beta and Anxious-Depressive Symptoms in Cognitively Normal Older Adults.

open access: yesAmerican Journal of Psychiatry, 2018
OBJECTIVE To understand the role of depressive symptoms in preclinical Alzheimer's disease, it is essential to define their temporal relationship to Alzheimer's proteinopathies in cognitively normal older adults.

Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]

open access: yes, 2009
The cause(s) of sporadic Alzheimer's disease (sAD) are complex and currently poorly understood. They likely result from a combination of genetic, environmental, proteomic and lipidomic factors that crucially occur only in the aged brain.

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

Amyloid-beta mediates homeostatic synaptic plasticity [PDF]

open access: yesThe Journal of Neuroscience, 2020
ABSTRACTThe physiological role of the amyloid-precursor protein (APP) is insufficiently understood. Recent work has implicated APP in the regulation of synaptic plasticity. Substantial evidence exists for a role of APP and its secreted ectodomain APPsα in Hebbian plasticity.

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Structure-based discovery of fiber-binding compounds that reduce the cytotoxicity of amyloid beta. [PDF]

open access: yes, 2013
Amyloid protein aggregates are associated with dozens of devastating diseases including Alzheimer's, Parkinson's, ALS, and diabetes type 2. While structure-based discovery of compounds has been effective in combating numerous infectious and metabolic ...

The Effect of 24-Hydroxy Cholesterol on Production of Reactive Oxygen Species (ROS) in Cultured Astrocytes Treated by Beta Amyloid

open access: yesمجله دانشکده پزشکی اصفهان, 2018
Background: Alzheimer's disease is a neurodegenerative disorder characterized by the accumulation of beta-amyloid plaques outside the cells, and intracellular hyperphosphorylation of tau protein.

Oxysterol-Binding Protein-1 (OSBP1) Modulates Processing and Trafficking of the Amyloid Precursor Protein [PDF]

open access: yes, 2008
BACKGROUND Evidence from biochemical, epidemiological and genetic findings indicates that cholesterol levels are linked to amyloid-β (Aβ) production and Alzheimer's disease (AD). Oxysterols, which are cholesterol-derived ligands of the liver X receptors
