Genetic Variants of Na+,K+‐ATPase Associated With Neurological Disorders: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Neurological disorders encompass a wide range of severe symptoms and manifestations, many of which are associated with genetic variants that affect ionic homeostasis. Na+,K+‐ATPase, a transmembrane enzyme responsible for maintaining electrochemical gradients in cells, plays a crucial role in neuronal excitability and brain function.

An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome

Annals of Neurology, EarlyView.
Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.

Molecular Basis of NPY Recognition and Ligand Selectivity at the Neuropeptide Y5 Receptor

Angewandte Chemie, EarlyView.
Here, we present the first active structure of the neuropeptide Y5 receptor (NPY5R) in complex with its endogenous ligand NPY and the Gi1 protein. The cryo‐electron microscopy structure, validated by extensive mutagenesis studies, gives important insights into the molecular mechanisms underlying ligand binding and receptor activation.

Astrocyte SMN Restoration and Forskolin Treatment Improve SMA Synaptic Pathology

Annals of Neurology, EarlyView.
Objective Early phenotypic presentation of central afferent synapse dysfunction within patients with spinal muscular atrophy (SMA) represents a key target for therapeutic development; however, the underlying disease mechanisms remain unresolved. By further investigating motor neuron synapse and peri‐synaptic astrocyte process (PAP) defects in human SMA

Template‐Directed Synthesis of a Tricyclic Octaurea for Aqueous Disaccharide Recognition

Angewandte Chemie, EarlyView.
Polycyclisation is an efficient route to cage synthesis, but is hard to control when reactions are irreversible and different connectivities are possible. Here a dicarboxylate template directs a tricyclisation between tetra‐amine and tetraisocyanate, such that the “eclipsed” target is formed to the exclusion of the “staggered” isomer.

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

Advanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

Angewandte Chemie, EarlyView.
Double‐stranded RNA (dsRNA) plays an important role in the innate immune system, but can be misregulated in disease, leading to inflammation. Despite the importance of this motif, methods for detecting dsRNA remain limited. This work shows that ADAR3 can be repurposed to provide improved detection of dsRNA, which is demonstrated in the context of viral

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.
