Macrophage TRIM21 Inhibition Ameliorates Murine Acute Pancreatitis via PHB2‐Mediated Mitochondrial Stabilization

open access: yesAdvanced Science, EarlyView.
Macrophage‐derived TRIM21 drives the progression of AP via ubiquitin‐proteasome‐mediated degradation of PHB2, leading to impaired PHB2‐mediated mitophagy. Therefore, accumulation of cytosolic mtDNA hyperactivates the cGAS‐STING signaling axis, thereby amplifying inflammatory cascades.

Antagonistic Ubiquitin Switching by USP7 and RNF40 Orchestrates KDM6A Homeostasis to License Coronavirus Susceptibility

open access: yesAdvanced Science, EarlyView.
We identify an antagonistic ubiquitin circuit that controls cellular permissiveness to multiple coronaviruses. The deubiquitinase USP7 stabilizes the epigenetic regulator KDM6A to upregulate viral receptors, while the E3 ligase RNF40 degrades KDM6A by catalyzing K6/K11‐ubiquitin chains of KDM6A for autophagic degradation.

Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

open access: yesAdvanced Science, EarlyView.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

open access: yesAdvanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

open access: yesAdvanced Science, EarlyView.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...
