An Investigation of Sleep Macro‐ and Microarchitecture by APOE Genotype

Annals of Neurology, EarlyView.
Objectives Apolipoprotein E ε4 (APOE ε4), a robust genetic risk factor for Alzheimer's disease (AD) is associated with functional connectivity deficits and amyloid pathology in brain regions involved in sleep regulation. Thus, alterations in sleep architecture may be one pathway through which ε4 contributes to Alzheimer's disease vulnerability. However,

Modifications of Lysine Residues 294 and 311 Within the Microtubule‐Binding Region Alter Tau Aggregation and Tubulin Binding Equilibria

Angewandte Chemie, EarlyView.
The molecular consequences of specific lysine modifications in Alzheimer´s disease remain insufficiently resolved in the context of full‐length protein. Here we integrate protein semisynthesis, segmental isotope labelling, and high‐resolution NMR spectroscopy to achieve residue‐resolved interrogation of site‐specific acetylation and carboxymethylation.

Multimodal Characterization of Glymphatic‐Related Magnetic Resonance Imaging Markers in Huntington's Disease: A Multi‐Cohort Retrospective Study

Annals of Neurology, EarlyView.
Objective To characterize magnetic resonance imaging (MRI)‐based glymphatic surrogates in Huntington's disease (HD) using MRI measures of perivascular diffusivity and structural perivascular alterations across multiple large cohorts. Methods We analyzed 2,731 MRI sessions from 880 participants across 3 large retrospective HD cohorts.

Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

Angewandte Chemie, EarlyView.
High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Genetic Resilience and Resistance in Alzheimer's Disease Diagnosis and Pathology

Annals of Neurology, EarlyView.
Objective Some individuals avoid Alzheimer's disease (AD) pathology as they age, or retain cognition despite substantial pathology, suggesting mechanisms of resistance or resilience to neurodegeneration. Educational attainment (EA) is associated with reduced risk of cognitive decline, although the underlying mechanisms remain unclear.

Distinct Molten‐Globule Conformations in an Interacting Protein Domain Resolved by 19F NMR of Fluoroproline Residues

Angewandte Chemie, EarlyView.
Modifying the conformational ensemble of “molten‐globule” protein by the site‐specific incorporation of stereoisomeric 4‐fluoroproline residues modulated its binding affinity and aggregation behavior. 19F NMR spectroscopy enabled the detection of key interactions responsible for structural and dynamic changes. ABSTRACT Recently, the application of deep

Biophysical Characterization and Proteomic Analysis of Small Extracellular Vesicles Derived From Different Neural Cell Lines

Advanced NanoBiomed Research, EarlyView.
This study systematically compares small extracellular vesicles (sEVs) derived from four neural cell lines, revealing how cellular origin shapes vesicle biophysical properties and proteomic cargo. Distinct, lineage‐specific signatures linked to neuronal, astrocytic, and microglial functions are identified, highlighting the importance of cell source ...

Beyond Simple Mimicry: Next‐Generation Geometric Architectures and Future Paradigms in Small‐Molecule and Macrocyclic Peptidomimetics

Angewandte Chemie, EarlyView.
Peptide‐to‐Small Molecule Paradigm: Peptidomimetics have evolved from simple mimicry toward drug‐like scaffolds supported by increasing clinical successes. This Perspective highlights the geometric design principles—linear repetition, convergent fusion, and cyclization—defining the next‐generation peptidomimetic architectures capable of targeting ...
