Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy
Advanced Science, EarlyView.A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation

Advanced Science, EarlyView.Ru–Mn composite nanozymes are engineered to mimic dual‐enzyme cascade catalysis, enabling efficient ROS clearance and neuroinflammation suppression. In collagenase‐ and autologous blood‐induced ICH mouse models, intranasal and intravenous administration reduced hematoma volume, preserved BBB integrity, and improved neurological recovery.

DADA Enhances CD8+ T Cell Stemness to Improve Anti‐Tumor Immunity and Immunotherapy Efficacy
Advanced Science, EarlyView.Diisopropylamine dichloroacetate (DADA) enhances CD8+ T cell stemness by improving OXPHOS and mitochondrial fitness in a PDK1‐depenpendent manner. This metabolic shift strengthens CD8+ T cell anti‐tumor immunity, improves responses to PD‐1 blockade, and endows CAR‐T cells with prolonged persistence and resistance to terminal exhaustion, highlighting a ...

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity
Advanced Science, EarlyView.This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Advanced Science, EarlyView.Upon NIR irradiation at 808 nm, the activity of TRPV4 was inhibited by M2M@BPSC, which led to reduced calcium influx, mitochondrial protection, and, importantly, the transcriptional activation of the STAT6‐EGR2 pathway. The improved macrophage function indirectly readjusts the equilibrium between C‐ECM and F‐ECM to reconstruct a suitable ...

Advanced Science, EarlyView.ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

Effects of dust accumulation and removal on radiators surfaces on Mars [PDF]
Tests were carried out to assess the impact of wind blown dust accumulation and abrasion on radiator surfaces on Mars. High emittance arc-textured copper and niobium-1 percent-zirconium samples were subjected to basaltic dust laden wind at Martian ...
