Structure of amyloid-β (20-34) with Alzheimer's-associated isomerization at Asp23 reveals a distinct protofilament interface. [PDF]
, 2019 Amyloid-β (Aβ) harbors numerous posttranslational modifications (PTMs) that may affect Alzheimer's disease (AD) pathogenesis. Here we present the 1.1 Å resolution MicroED structure of an Aβ 20-34 fibril with and without the disease-associated PTM, L ...

Chemical Approaches for Array Based Detection of Amyloids
Advanced Sensor Research, EarlyView.Amyloids are protein aggregates with both pathological and functional roles. Their detection is challenged by structural polymorphism, isoform diversity, and dynamic aggregation behavior. This review presents chemical array‐based sensing strategies that address these complexities, emphasizing fluorescence and colorimetric methods, alongside ...

Advanced Science, EarlyView.Short‐term intravenous treatments with iPSC‐derived mononuclear phagocytes (iMPs) improve cognitive decline and neural health in two mouse models of aging and in the 5xFAD mouse model of Alzheimer's disease. iMPs reduce levels of serum amyloid proteins that increase in aging and improve the health of hippocampal microglia and mossy cells.

Amyloid β-sheet mimics that antagonize protein aggregation and reduce amyloid toxicity. [PDF]
, 2012 The amyloid protein aggregation associated with diseases such as Alzheimer's, Parkinson's and type II diabetes (among many others) features a bewildering variety of β-sheet-rich structures in transition from native proteins to ordered oligomers and ...

Advanced Science, EarlyView.The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Navigating Transition Metal‐Dependent Cell Death: Mechanisms, Crosstalk, and Future Directions
Advanced Science, EarlyView.Transition metals trigger distinct regulated cell death pathways beyond traditional apoptosis. This review examines ferroptosis (iron‐catalyzed lipid peroxidation) and cuproptosis (copper‐induced mitochondrial proteotoxicity), while exploring hypothetical “cobaltosis” as a novel pathway.
