Ribonucleotides Amplify Mitochondrial DNA‐Driven cGAS–STING Activation via FdUMP‐ribonucleotide Hybrid Particles to Potentiate Chemoimmunotherapy

open access: yesAdvanced Science, EarlyView.
This work develops a metabolic sharing strategy that employs cytidine monophosphate (CMP) to competitively reprogram floxuridine (FUDR) pyrimidine metabolism in colorectal tumor cells. Elevated intracellular FdUMP induces nucleotide imbalance, drives mitochondrial DNA release and cGAS‐STING innate immune cascade activation, and potentiates robust ...

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

open access: yesAdvanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

open access: yesAdvanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

Sex‐ and Time‐Resolved Physiological and Gut Ecosystem Responses to a Food‐Grade Microbiome‐Targeted Intervention in Collegiate Endurance Athletes

open access: yesAdvanced Science, EarlyView.
In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

Multifunctional Zinc Glycyrrhizinate‐Integrated Gel for Enhanced Probiotic Delivery and Alleviation of Acute and Spontaneous Colitis

open access: yesAdvanced Science, EarlyView.
Multifunctional oral delivery system—L. reuteri@ZGM—act as both a carrier and therapeutic adjuvant, providing ROS scavenging, and mucin‐interactive properties tailored to the IBD microenvironment. This bioactive gel safeguards L. reuteri from gastric degradation, enhances mucosal adhesion, and promotes long‐term retention at inflamed sites, thereby ...

Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

Spatial Transcriptomics Reveals a T Cell‐Mediated Microglial Activation Axis of Immune Checkpoint Inhibition‐Related Adverse Events in the Brain

open access: yesAdvanced Science, EarlyView.
Immune checkpoint inhibition (ICI) reshapes the hippocampal neuroimmune niche. Spatial transcriptomic profiling and human brain histological analyses identify neuroinflammation and altered neuronal and glial programs. Notably, T cell depletion prevents ICI‐driven microglial activation, establishing the T cell–microglia crosstalk axis as a driving ...

Decoding the Neural Circuit Underlying Context‐Cue Association in Retrieval of Morphine Reward Memory

open access: yesAdvanced Science, EarlyView.
Contextual cues recruit the glutamatergic vCA1–dmPFC pathway to retrieve morphine reward memory by reshaping cell‐type‐specific prefrontal microcircuit activity. Distinct regulation of PV+ and SST+ interneurons defines this hippocampal–prefrontal mechanism.

Adhesion‐Enhanced Engineered Probiotic for Prolonged Intestinal Retention and Calprotectin‐Responsive IBD Therapy

open access: yesAdvanced Science, EarlyView.
An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.
