Selective inhibition of phosphodiesterases 4, 5 and 9 induces HSP20 phosphorylation and attenuates amyloid beta 1-42 mediated cytotoxicity [PDF]
, 2016 Phosphodiesterase (PDE) inhibitors are currently under evaluation as agents that may facilitate the improvement of cognitive impairment associated with Alzheimer's disease. Our aim was to determine whether inhibitors of PDEs 4,5 and 9 could alleviate the

Neuronal C/EBPβ Shortens the Lifespan via Inactivating NAMPT
Advanced Science, EarlyView.Schematic diagram illustrating the mechanism of shortened lifespan in Thy 1‐C/EBPβ transgenic mice and intervention strategies. Briefly, C/EBPβ/AEP escalation in the aging brain triggers NAMPT fragmentation and NAD+ depletion. Knockout of AEP from Thy 1‐C/EBPβ Tg/Tg mice ameliorates cognitive impairments and elongates the lifespan.

Identification of Causal Relationship between Amyloid-beta Accumulation and Alzheimer's Disease Progression via Counterfactual Inference [PDF]
arXiv, 2023 Alzheimer's disease (AD) is a neurodegenerative disorder that is beginning with amyloidosis, followed by neuronal loss and deterioration in structure, function, and cognition. The accumulation of amyloid-beta in the brain, measured through 18F-florbetapir (AV45) positron emission tomography (PET) imaging, has been widely used for early diagnosis of AD.

Molecular Dynamics Studies on 3D Structures of the Hydrophobic Region PrP(109-136) [PDF]
, 2013 Prion diseases caused by the conversion from a soluble normal cellular prion protein into insoluble abnormally folded infectious prions, are invariably fatal and highly infectious degenerative diseases that affect a wide variety of mammalian species. The

Thermodynamic selection of steric zipper patterns in the amyloid cross-beta spine. [PDF]
PLoS Computational Biology, 2009 At the core of amyloid fibrils is the cross-beta spine, a long tape of beta-sheets formed by the constituent proteins. Recent high-resolution x-ray studies show that the unit of this filamentous structure is a beta-sheet bilayer with side chains within ...

Advanced Science, EarlyView.Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.

Listerin Alleviates Alzheimer's Disease through IRE1‐mediated Decay of TLR4 mRNA
Advanced Science, EarlyView.Alzheimer's disease (AD) progression is influenced by microglia‐mediated neuroinflammation. Here, it is demonstrated that Listerin suppresses neuroinflammatory signaling and cognitive impairment in AD models by triggering IRE1α‐mediated TLR4 mRNA decay. Adenoviral Listerin delivery reduces amyloid‐β pathology, positioning it as a new therapeutic target.

PDB_Amyloid: The Extended Live Amyloid Structure List from the PDB [PDF]
arXiv, 2018 The Protein Data Bank (PDB) contains more than 135 000 entries today. From these, relatively few amyloid structures can be identified, since amyloids are insoluble in water. Therefore, mostly solid state NMR-recorded amyloid structures are deposited in the PDB.

The role of astrocytes in Alzheimer's disease, A systematic review
Journal of Current Oncology and Medical Sciences, 2023 Introduction: Alzheimer's disease (AD), the most common neurodegenerative disease in the world, appears in two forms, early and late. Pathologically, an amyloid beta peptide is the hallmark of this disease which is followed by synaptic dysfunction, brain
