Integrated Single‐Cell and Spatial Analysis Reveals a Metabolic‐Immune Axis Driving Aortic Dissection

Advanced Science, EarlyView.
Single‐cell and spatial profiling of 110 human thoracic aortic samples reveals a stromal–immune circuit driving aortic dissection. An elastin‐rich fibroblast subset is depleted with age and markedly reduced in disease, weakening aortic wall integrity.

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

Drug‐Induced Cuproptosis Defines the Therapeutic Window of Celecoxib in Intervertebral Disc Degeneration via the HSP90‐RBX1 Axis

Advanced Science, EarlyView.
This study reveals the dual role of celecoxib in intervertebral disc degeneration. While low concentrations are protective, high concentrations induce toxicity by upregulating HSP90, which synergizes with USP15 to deubiquitinate and stabilize RBX1. This leads to degradation of COMMD1/ATP7B, copper dyshomeostasis, and ultimately, cuproptosis.

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation

Advanced Science, EarlyView.
By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...

Spike‐Embedded Nanocatalysts via Metal‐Directed Carbonization for Highly Efficient and Robust Semi‐Hydrogenation

Advanced Science, EarlyView.
A metal‐directed carbonization strategy transforms hierarchical organic microspheres into spiky carbon catalysts with Pd nanoparticles embedded at the tips. This approach resolves the activity‐stability trade‐off, achieving exceptional poison resistance in semi‐hydrogenations, offering a versatile, scalable platform for designing high‐performance ...

ZDHHC18‐Mediated Palmitoylation of ORF3a Promotes SARS‐CoV‐2 Pathogenesis by Antagonizing TRIM16‐Mediated Ubiquitination and Proteasomal Degradation

Advanced Science, EarlyView.
Palmitoylation by ZDHHC18 blocks ORF3a K27‐linked ubiquitination mediated by TRIM16, thereby preventing its proteasomal degradation and strengthening viral pathogenesis. Targeting palmitoylation through a pharmacological inhibitor (2‐BP), a competitive inhibitory peptide (OPIP), or adenovirus‐mediated knockdown of ZDHHC18 expression presents a ...

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

Advanced Science, EarlyView.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

DMS‐MaPseq and DREEM Analyses Implicate the Critical Role of RNA Structural Dynamics in Turnip Yellow Mosaic Virus Pathogenicity

Advanced Science, EarlyView.
RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

W‐N‐C Tandem Catalytic Centers Mediating Efficient Charge Transfer for the Enhanced Radical‐Path U(VI) Photoreduction

Advanced Science, EarlyView.
This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

Trace Ru‐Doped PtCuRu@PtRu Core‐Shell Electrocatalyst for CO‐Resilient Methanol Oxidation

Advanced Science, EarlyView.
We engineered a trace Ru‐doped PtCuRu@PtRu core‐shell nanostructure. This design exploits lattice mismatch‐induced compressive strain between the PtCuRu ternary core and trace Ru‐doped Pt‐rich shell, systematically downshifting the Pt d‐band center to weaken *CO adsorption energetics.
