Dual Covalent Targeting of STING Cysteines 292/309 Disrupts Functional Oligomerization and Enables Potent Antagonist Development

Advanced Science, EarlyView.
We report a rational design strategy for STING antagonists by dual covalent targeting of Cys292/309 in its C‐terminal domain, directly preventing functional oligomerization. Through covalent warhead repurposing, we identified P005091 and revealed its unique dual‐cysteine mechanism.

Glucuronolactone Promotes Mucin Sulfation to Alleviate Deoxynivalenol‐Induced Intestinal Injury via Microbiota‐Dependent and ‐Independent AHR Activation

Advanced Science, EarlyView.
Glucuronolactone (GLU) as a natural metabolite of glucose, increases Lactobacillus amylovorus abundance and luminal IAA level to activate AHR signaling. In addition, GLU itself can directly elevate AHR signaling activity independently of microbiota and IAA.

Construction of a MOF‐Based Snap‐Top Delivery Nanosystem for Powerful Dual‐Responsive Synergistic Colitis Treatment

Advanced Science, EarlyView.
A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Immunomodulatory effect of Dicrocoelium dendriticum ova on DSS-induced experimental colitis in C57BL/6 mouse

Scientific Reports
Inflammatory bowel disease (IBD) significantly diminishes an individual’s quality of life and increases the risk of colorectal cancer. Recent clinical and experimental findings suggest that infection with parasitic helminths may suppress the development ...

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

Advanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Engineered Bacterial Ligand From Streptococcus pneumoniae on Macroporous Resins for Selective Affinity Capture of Secretory IgA

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Secretory immunoglobulin A (sIgA) is a promising emerging biopharmaceutical candidate, but it currently lacks a standardized platform for purification. To address this, a novel affinity chromatography resin was developed by immobilizing protein variants of the Streptococcus pneumoniae surface protein, SpsA, as an affinity ligand.
