Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

open access: yesAdvanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

A guide to selecting high-performing antibodies for amyloid-beta precursor protein for use in Western Blot, immunoprecipitation and immunofluorescence [version 2; peer review: 2 approved, 1 approved with reservations]

open access: yesF1000Research
The amyloid-beta precursor protein is a transmembrane protein expressed in many tissues and highly concentrated in the brain. The protein is of significant interest due to its involvement in the generation of amyloidogenic β-amyloid peptides, prone to ...

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths

open access: yesAdvanced Science, EarlyView.
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...

FMRP mediates mGluR5-dependent translation of amyloid precursor protein.

open access: yesPLoS Biology, 2007
Amyloid precursor protein (APP) facilitates synapse formation in the developing brain, while beta-amyloid (Abeta) accumulation, which is associated with Alzheimer disease, results in synaptic loss and impaired neurotransmission.

Deposition of amyloid fibrils promotes cell-surface accumulation of amyloid β precursor protein

open access: yesNeurobiology of Disease, 2004
Amyloid β protein (Aβ) deposition and neuronal degeneration are characteristic pathological features of Alzheimer's disease (AD). In vitro, Aβ fibrils (fAβ) induce neuronal degeneration reminiscent to AD, but the mechanism of neurotoxicity is unknown ...

Supramolecular Degraders: An Emerging Paradigm in Targeted Protein Degradation

open access: yesAdvanced Science, EarlyView.
Dynamic supramolecular assembly reshapes targeted protein degradation by coordinating modular degrader construction, delivery, functional integration, and intracellular assembly or activation across proteasomal, endosomal–lysosomal, and autophagy–lysosomal pathways.

The copper-amyloid-beta-peptide complex of Alzheimer’s disease: affinity, structure, fibril formation and toxicity [PDF]

open access: yes, 2010
PhDSenile plaques of Alzheimer’s disease (AD) patients are composed primarily of the amyloid-β-peptide peptide (Aβ), and within these plaques Cu2+ ions are found concentrated and directly bound to Aβ.

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Near‐Infrared Fluorescent PROTAC Enables Theranostic Imaging and Selective Tau Degradation in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Here, we report a novel NIR fluorescent PROTAC platform that enables real‐time imaging and targeted degradation of Alzheimer's p‐Tau. Our lead compound effectively clears p‐Tau, reduces APP/Aβ, and alleviates cognitive deficits in AD mice. This work demonstrates a theranostic strategy for visualizing degradation and developing next‐generation AD ...
