Highly Active Cu14 Cluster Precisely Activates Autophagy Inhibitor to Amplify Cuproptosis Immunotherapy

Advanced Science, EarlyView.
An atomically precise Cu14 cluster‐mediated bond scission reaction pioneers the amplification of the antitumor immune response via synergetic cuproptosis‐associated immunogenic cell death induction and in situ autophagy blockade. ABSTRACT Transition metal‐mediated cleavage mechanisms have emerged as an effective means to mitigate the off‐target ...

High fat diet deviates PtC-specific B1 B cell phagocytosis in obese mice [PDF]

, 2014
Phagocytosis had been attributed predominantly to "professional" phagocytes such as macrophages, which play critical roles in adipose tissue inflammation.

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, EarlyView.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

Hierarchical Targeting of TREM2+ Myeloid Cells via Acid‐Triggered OMVs Reprogram Immunosuppression and Suppress Osteolysis in Bone‐Metastatic TNBC

Advanced Science, EarlyView.
This study developed a hierarchical targeting nanoplatform, siTREM2@ETP‐PEOz‐OMVs, against triple‐negative breast cancer (TNBC) bone metastasis. It precisely delivers therapeutic siTREM2 to monocytes/macrophages within the metastatic niche. This intervention dually regulates cell fate: reprogramming immunosuppressive macrophages and inhibiting ...

Chemotactic predator-prey dynamics

, 2010
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady ...

Biomimetic Ru‐Mn Nanozyme with Cascade Catalytic Activity Attenuates Secondary Brain Injury in Intracerebral Hemorrhage

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.

Distinct Spatiotemporal Distribution of Bacterial Toxin-Produced Cellular cAMP Differentially Inhibits Opsonophagocytic Signaling

Toxins, 2019
Myeloid phagocytes have evolved to rapidly recognize invading pathogens and clear them through opsonophagocytic killing. The adenylate cyclase toxin (CyaA) of Bordetella pertussis and the edema toxin (ET) of Bacillus anthracis are both calmodulin ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.
