A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

open access: yesAdvanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota

open access: yesAngewandte Chemie, EarlyView.
Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

Microbial Biosensor for Sensing and Treatment of Intestinal Inflammation

open access: yesAdvanced Science, EarlyView.
The engineered calprotectin biosensor detects gut inflammation, processes the signal through genetic regulation, and responds by expressing the reporter sfGFP and the therapeutic protein secIL10. This dual functionality enables the engineered biosensor not only to sense but also to mitigate gut inflammation, highlighting its potential for disease ...

Structural Basis for the Catalytic Mechanism of ATP‐Dependent Diazotase CmaA6

open access: yesAngewandte Chemie, EarlyView.
Several diazotases have been reported in recent years, but the detailed catalytic mechanism is unclear. From X‐ray crystallography and Cryo‐EM analysis, we obtained the structure of a diazotase CmaA6, which synthesizes 3‐diazocoumaric acid. Kinetic analysis and computational analysis indicated that CmaA6 catalyzes diazotization via an unprecedented ...

Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

open access: yesAdvanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Trypstatin as a Novel TMPRSS2 Inhibitor with Broad‐Spectrum Efficacy against Corona and Influenza Viruses

open access: yesAdvanced Science, EarlyView.
Trypstatin, a 61‐amino acid Kunitz‐type protease inhibitor derived from human Bikunin, potently inhibits TMPRSS2 and related proteases. It blocks spike‐ and hemagglutinin‐mediated entry of multiple respiratory viruses in vitro reduces SARS‐CoV‐2 replication in human airway cultures, and lowers viral load and symptoms in infected hamsters, demonstrating
