Dual‐Key Genetic Circuit Enables Stable and Self‐Regulated Engineered Bacteria for the Treatment of Ulcerative Colitis

Advanced Science, EarlyView.
A self‐regulated Escherichia coli Nissle 1917 strain equipped with a dual‐key genetic circuit achieved antibiotic‐free stability and programmable lysis for therapeutic protein delivery. By co‐expressing an IL‐2 mutant and Amuc_1100, the engineered bacteria restored immune balance and epithelial integrity, providing a safe and precise approach for ...

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

Advanced Science, EarlyView.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

Synbiotics suppress colitis-induced tumorigenesis in a colon-specific cancer mouse model.

PLoS ONE, 2019
Although synbiotics may be effective in maintaining remission of inflammatory bowel disease, their anticarcinogenic effects are still debated. To address this issue, we evaluated the effects of synbiotics, probiotics, and prebiotics on tumorigenesis ...

Adhesion‐Related Macrophages Regulate Metabolic Homeostasis Through CAV‐1 Dependency

Advanced Science, EarlyView.
Adipose tissue harbors a distinct macrophage subpopulation, termed adhesion‐related macrophages (ARMs), which stably adhere to adipocytes. In obesity, ARMs represent the major expanding macrophage subset. They acquire material from adipocytes and rely on Caveolin‐1 for sustained lipid handling.

Rapid RNA Exchange in Aqueous Two-Phase System and Coacervate Droplets [PDF]

, 2014
Compartmentalization in a prebiotic setting is an important aspect of early cell formation and is crucial for the development of an artificial protocell system that effectively couples genotype and phenotype. Aqueous two-phase systems (ATPSs) and complex

Loss of VMP1 Impairs Tight Junction Recycling and Aggravates Intestinal Barrier Dysfunction in Inflammatory Bowel Disease

Advanced Science, EarlyView.
This study identifies vacuole membrane protein 1 (VMP1) as a critical regulator of intestinal epithelial barrier homeostasis. VMP1 facilitates the recruitment of CORO1C to late endosomes, supporting Retromer‐mediated recycling of the tight junction protein Occludin.

Stabilizing Water-in-Water Emulsions Using Oil Droplets

Molecules
The production of water-in-water emulsion droplets, the coalescence of which is prevented by adding oil-in-water micrometric droplets, is reported. Hexadecane (O) and cetyl trimethyl ammonium bromide (CTAB) were added to a W/W emulsion made of dextran ...
