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

Advanced 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.

Targeted Degradation of eEF2K by a Structure‐Guided PROTAC Strategy for the Treatment of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
This study developed an eEF2K‐targeting PROTAC, A6, that efficiently degrades eEF2K in TNBC cells, inhibiting tumor growth in vitro and in vivo. To enhance tumor‐specific delivery, we engineered A6@ZIF‐8, a pH‐sensitive nanocarrier, which improved drug accumulation at tumor sites, offering a promising therapeutic strategy for TNBC through targeted ...

Cascade Therapy of Periodontitis via Sequential Release of Ribosome‐Targeting Antimicrobial Peptide and Irisin From a Multifunctional MOF‐Based System

Advanced Science, EarlyView.
This study presents a novel strategy for periodontitis treatment by co‐delivering a membrane‐ and ribosome‐targeting antimicrobial peptide GF and Irisin through a pH‐responsive metal‐organic framework. The system enables sequential release, providing rapid antibacterial action, anti‐inflammatory and antioxidative effects, as well as promoting bone ...

Defect‐Rich 2D Layered Double Hydroxides Enhance Sonodynamic Antibacterial Therapy

Advanced Science, EarlyView.
This study develops defect‐rich ultrathin ZnCuW‐LDH nanosheets (DR‐ZnCuW‐LDH) via acid etching. DR‐ZnCuW‐LDH exhibits fourfold enhanced US‐triggered ROS production due to oxygen defects and electronic modulation, demonstrating potent antibacterial efficacy in vitro/vivo.

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.
