Plasmon‐Induced Optothermal Manipulation of Colloidal Particles and Biological Entities Resilient to Saline Environments

Advanced Optical Materials, EarlyView.
The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Bacterial Outer Membrane Vesicles Induce Plant Immune Responses

Molecular Plant-Microbe Interactions, 2016
Gram-negative bacteria continuously pinch off portions of their outer membrane, releasing membrane vesicles. These outer membrane vesicles (OMVs) are involved in multiple processes including cell-to-cell communication, biofilm formation, stress tolerance,

Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.

Specific labeling of outer membrane vesicles with antibiotic-conjugated probe reveals early bacterial infections in blood

Nature Communications
Bacterial outer membrane vesicles (OMVs) are nano-sized structures derived from the outer membrane of Gram-negative bacteria, which have emerged as key players in host-pathogen interactions, yet their potential as biomarkers remains largely unexplored ...

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Protein Targeting to the Bacterial Cytoplasmic Membrane [PDF]

, 1999
Proteins that perform their activity within the cytoplasmic membrane or outside this cell boundary must be targeted to the translocation site prior to their insertion and/or translocation.
