An Avalanche Effect Nanomodulator Triggers Cascade Ferroptosis/Cuproptosis for Immunosuppressive Microenvironment Remodeling

Advanced Science, EarlyView.
A nanomodulator called L‐Arginine/lificiguat@Copper‐hollow Prussian blue@Calcium phosphate nanoparticles is constructed to launch a self‐amplifying “avalanche effect” in tumor cells. The ensuing cascade, triggered by the acidic tumor microenvironment and near‐infrared light, induces calcium overload, generates a reactive oxygen species and reactive ...

Dual‐Responsive Hydrogels Integrate Bioelectrical Stimulation and Piezo‐Photocatalysis for Regenerative Treatment of Infected Wounds

Advanced Science, EarlyView.
A wireless, dual‐responsive hydrogel (PVA/(PVDF‐TrFE)/BiOClBr@PDA) is developed to promote efficient regeneration of infected wounds by integrating piezoelectric stimulation with piezo‐photocatalytic pathways. Under simultaneous light and ultrasonic stimulation, the hydrogel generates therapeutic electrical cues and reactive oxygen species, disrupting ...

Liquid Gallium Nanozyme Coatings Enable Sustained Nitric Oxide Generation With Antioxidant and Anti‐Inflammatory Functions

Advanced Science, EarlyView.
Liquid gallium (Ga) acts as a catalytic center for nitric oxide (NO) generation within a tannic acid–zirconium metal–phenolic network coating. Stabilized Ga nanoparticles catalyze S‐nitrosothiol decomposition through surface electron transfer, enabling controlled NO production, enhancing endothelial biocompatibility, and providing antioxidant and anti ...

Non-hemolytic activity of ntATX-D1 and ntATX-D2.

The hemolytic activity of purified ntATX-D1 and ntATX-D2 was evaluated using 5% defibrinated sheep blood agar plates. Wells were punched into the agar and loaded with 30 μL of purified proteins (10 μg/well) and incubated at 37°C overnight. The absence of

Disease‐Stage Synchronized Nanozyme Therapy for Polymicrobial Sepsis through Adaptive Catalytic and Immune Reprogramming

Advanced Science, EarlyView.
A disease‐stage synchronized nanozyme platform is developed to treat polymicrobial sepsis by adapting its functions to changing infection environments. The system eliminates multidrug‐resistant bacteria during early infection while reducing inflammation and restoring immune balance during recovery, providing an integrated strategy for infection control

Membrane-Pore Forming Characteristics of the Bordetella pertussis CyaA-Hemolysin Domain

Toxins, 2015
Previously, the 126-kDa Bordetella pertussis CyaA pore-forming/hemolysin (CyaA-Hly) domain was shown to retain its hemolytic activity causing lysis of susceptible erythrocytes. Here, we have succeeded in producing, at large quantity and high purity, the

Natural‐Inspired Engineered Microalgae With Selenium Enrichment Enabled Potent Anti‐Tumor Immunity

Advanced Science, EarlyView.
Se‐Ssp was engineered as a potent immunomodulator for activating innate immunity via the TLR and cGAS‐STING pathways, therefore converting “cold” tumors into “hot” tumors to achieve high efficacy and long‐term therapeutic outcomes. ABSTRACT Immunotherapy has shed light on clinical oncology for several decades.

One‐Step Immobilized Phage Depolymerase Coatings for Catheter‐Related Bloodstream Infections

Advanced Science, EarlyView.
Catheter‐related bloodstream infections (CRBSI) caused by drug‐resistant Gram‐negative bacteria remain a major clinical challenge. Here, a polydopamine‐assisted depolymerase coating degrades bacterial capsules and restores serum‐mediated killing, effectively suppressing biofilms and reducing bacterial burden in vitro, ex vivo, and in vivo, presenting a
