Analyzing Amyloid Beta Aggregates with a Combinatorial Fluorescent Molecular Sensor.
Journal of the American Chemical Society, 2017 Different amyloid beta (Aβ) aggregates can be discriminated by a combinatorial fluorescent molecular sensor. The unique optical fingerprints generated by the unimolecular analytical device provide a simple means to differentiate among aggregates ...

The role of lipid metabolism in neuronal senescence
FEBS Open Bio, EarlyView.Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Obstructive sleep apnea and amyloid-β42 in adolescents: The results of a pilot study
Acta Biomedica Scientifica, 2022 Background. Obstructive sleep apnea (OSA) is a chronic condition characterized by repetitive collapse of the upper airway during sleep leading to intermittent hypoxia, excessive arousals and disrupt of sleep homeostasis. OSA is associated with obesity as

Thermodynamics of beta-amyloid fibril formation
, 2004 Amyloid fibers are aggregates of proteins. They are built out of a peptide called $\beta$--amyloid (A$\beta$) containing between 41 and 43 residues, produced by the action of an enzyme which cleaves a much larger protein known as the Amyloid Precursor ...

Amyloid beta mediates memory formation [PDF]
Learning & Memory, 2009 The amyloid precursor protein (APP) undergoes sequential cleavages to generate various polypeptides, including the amyloid β (1–42) peptide (Aβ[1–42]), which is believed to play a major role in amyloid plaque formation in Alzheimer's disease (AD). Here we provide evidence that, in contrast with its pathological role when accumulated, endogenous Aβ in ...

Diversity of Amyloid-beta Proteoforms in the Alzheimer’s Disease Brain
Scientific Reports, 2017 Amyloid-beta (Aβ) plays a key role in the pathogenesis of Alzheimer’s disease (AD), but little is known about the proteoforms present in AD brain. We used high-resolution mass spectrometry to analyze intact Aβ from soluble aggregates and insoluble ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Introduction Neuronal pentraxin 2 (NPTX2) is a synaptic protein involved in synaptic plasticity and regulation of neuronal excitability. Lower baseline cerebrospinal fluid (CSF) NPTX2 levels have been shown to be associated with an earlier onset of mild cognitive impairment (MCI), a pre‐dementia syndrome, even after CSF Alzheimer's Disease (AD)

Cerebrospinal Fluid Tau, p-Tau 181 and Amyloid-beta(38/40/42) in Frontotemporal Dementias and Primary Progressive Aphasias [PDF]
, 2010 Background/Aims: We determined cerebrospinal fluid (CSF) concentrations of amyloid-beta(A beta)(1-38), A beta(1-40), A beta(1-42), total tau and phospho-tau (p-tau) in order to study their differential expression in frontotemporal dementia (FTD, n = 25 ...

Polyphenolic Biflavonoids Inhibit Amyloid-Beta Fibrillation and Disaggregate Preformed Amyloid-Beta Fibrils [PDF]
Biomolecules & Therapeutics, 2019 Alzheimer's disease (AD) is a devastating neurodegenerative disease and a major cause of dementia in elderly individuals worldwide. Increased deposition of insoluble amyloid β (Aβ) fibrils in the brain is thought be a key neuropathological hallmark of AD.
