An Enzyme‐Like Catalyzed Nanosheets for Redox Stress Oscillation Therapy Against Bacterial Infections

open access: yesAdvanced Science, EarlyView.
Bacterial biofilms form a physicochemical barrier. Their dense network structure and redox homeostasis confer high resistance to antimicrobial treatments and immune‐mediated killing and clearance. In this study, SnSe nanosheets with enzyme‐like properties and piezoelectric catalysis can oscillate to regulate bacterial redox homeostasis and improve the ...

Tumor Extracellular Vesicles lncOSLMT Drives Lung Inflammatory Premetastatic Niche Formation in Osteosarcoma via m6A‐Dependent hnRNPA2B1/COX‐2 Axis

open access: yesAdvanced Science, EarlyView.
Tumor‐derived extracellular vesicles program inflammatory lung premetastatic niches through selective delivery of long noncoding RNAs. This work reveals EVs‐associated lncOSLMT as a key driver of lung fibroblast activation via m6A‐dependent PTGS2 stabilization.

Advancing the Tendinopathy Triad: Comment on “Tendinopathy: The Interplay Between Mechanical Stress, Inflammation, and Vascularity”

open access: yesAdvanced Science, EarlyView.
Abstract Building upon the integrative framework of tendinopathy proposed by Gehwolf et al.—which elegantly connects mechanical stress, inflammation, and vascularity—this commentary extends the discussion by introducing novel mechanistic insights and future research directions that move beyond the established triad. A paradigm shift is proposed ...

Immunoaffinity‐Mimetic Assembly of Peptide‐Aptamer Conjugates and Stem Cell‐Derived Exosomes into Hierarchical Microgels for Spinal Cord Injury Repair

open access: yesAdvanced Science, EarlyView.
Inspired by antibody‐antigen binding, this study develops an unprecedented immunoaffinity‐mimetic assembly strategy, with Peptide‐AptCD63 conjugates acting as antibody surrogates binding CD63 epitopes on mesenchymal stem cell‐derived exosomes. This creates a hierarchical microstructure intended to synergistically integrate antioxidative and anti ...

Dual‐Anchored Clickable Peptide via SPAAC for Gelatinase‐Responsive Antibacterial and Osteogenic Functions on Titanium Implants

open access: yesAdvanced Science, EarlyView.
To address the infection‐associated orthopedic implant failures, this study presents a gelatinase‐responsive antibacterial titanium implant (Ti‐Dual) featuring a dual‐anchored fusion peptide containing antibacterial (HHC36) and osteogenic (RGD) domains connected by a cleavable GPLGV linker.

Mechanical Strain‐Programmed SDC1+ Sheath Fibroblasts Trigger CXCR4hi Neutrophil‐Mediated Enthesitis in Ankylosing Spondylitis

open access: yesAdvanced Science, EarlyView.
In ankylosing spondylitis (AS), mechanical strain‐programmed SDC1+ sheath fibroblasts secrete CXCL5 to recruit neutrophils and promote the activation of CXCR4hi neutrophils, thereby exacerbating enthesitis by promoting neutrophil extracellular traps (NETs) formation. SOX5 controls the generation of SDC1+ sheath fibroblasts via super‐enhancers.

Asymmetric Cu─N─Ru Bridgedsite Nanozyme‐Loaded Injectable Thermogel Boosts Cuproptosis‐Like Death for Multidrug‐Resistant Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

Self‐Assembled Myricetin‐Arginine Conjugate Nanozymes for Targeted Suppression of Joint Inflammation and Osteoclastogenesis in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Carrier‐free myricetin‐arginine conjugate nanozymes (MANZs) have been fabricated through a Mannich reaction and spontaneous self‐assembly. MANZs selectively accumulate in inflamed joints by targeting M1 macrophages via CAT2‐mediated uptake. The nanozymes can effectively modulate macrophage polarization, suppress osteoclast differentiation, and mitigate

Pearl‐Like Bioinspired Coating Enables Regulation of Mg Degradation for Osteoporotic Bone Repair

open access: yesAdvanced Science, EarlyView.
In this study, inspired by pearl architecture, we developed a layered Ca–P “brick” and Fn‐mimetic peptide “mortar” coating on Mg alloys. The Ca–P layer moderates corrosion and offers mineral cues, while the peptide enhances adhesion and regulates immune‐vascular responses.
