An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

Advanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

Endoplasmic Reticulum Geometry Dictates Neuronal Bursting via Calcium Store Refill Rates and Exposes Selective Neuronal Vulnerability

Advanced Science, EarlyView.
The ER's continuous tubular network is maintained by ER‐shaping proteins whose mutation or dysregulation contributes to neurodegenerative diseases. Here, we show that ER morphology sets the speed of Ca2+ store replenishment between firing events. Disrupting ER continuity slows intra‐ER Ca2+ redistribution from extracellular refill (SOCE) sites, driving

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

Advanced Science, EarlyView.
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...

Implications of virus-induced stress granules in tauopathies

Translational Neurodegeneration
Tauopathies are characterized by aberrant tau structure and function, which is associated with neurodegenerative dementias, such as Alzheimer’s disease, Pick’s disease, and frontotemporal dementia, as well as the motor neuron disease amyotrophic lateral ...

Electrostatic Effects on Tau Nanocondensates

Biomolecular condensates (BMCs) are membrane-less protein compartments with physiological and pathological relevance. The formation of BMCs is driven by a process known as liquid–liquid phase separation (LLPS), a field that has largely focused on ...

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Purification and Fibrillation of Recombinant Human Amyloid-β, Prion Protein, and Tau Under Native Conditions

, 2018
Protein misfolding, aggregation, and amyloid formation is involved in a large number of diseases. Recombinantly expressed proteins to study the amyloid fibril formation process are important for mechanistic studies.
