Probiotic Escherichia coli Nissle 1917 inhibits leaky gut by enhancing mucosal integrity.

open access: yes, 2007
BackgroundProbiotics are proposed to positively modulate the intestinal epithelial barrier formed by intestinal epithelial cells (IECs) and intercellular junctions. Disruption of this border alters paracellular permeability and is a key mechanism for the

Targeting the Mucosal Barrier: How Pathogens Modulate the Cellular Polarity Network [PDF]

open access: yes, 2017
The mucosal barrier is composed of polarized epithelial cells with distinct apical and basolateral surfaces separated by tight junctions and serves as both a physical and immunological barrier to incoming pathogens.

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

open access: yesAdvanced 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

The therapeutic management of gut barrier leaking: the emerging role for mucosal barrier protectors

open access: yes, 2015
Gut barrier is a functional unit organized as a multi-layer system and its multiple functions are crucial for maintaining gut homeostasis. Numerous scientific evidences showed a significant association between gut barrier leaking and gastro-intestinal ...

Transferable Deep Reinforcement Learning With Edge‐Contour‐Depth Fusion for Autonomous Wireless Capsule Endoscopy Navigation

open access: yesAdvanced Science, EarlyView.
This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Intestinal damage precedes mucosal immune dysfunction in SIV infection

open access: yes, 2018
HIV and pathogenic SIV infection are characterized by mucosal dysfunction including epithelial barrier damage, loss of Th17 cells, neutrophil infiltration, and microbial translocation with accompanying inflammation.

Engineering Microbial Particles for Next‐Generation Biomedical Platforms

open access: yesAdvanced Science, EarlyView.
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Intestinal Source Control of Lipid Metabolism by Enzyme‐Probiotic Encapsulated, Spatiotemporal Crosslinked, and Small Intestine‐Adhesive Hydrogel Microspheres

open access: yesAdvanced Science, EarlyView.
A thiol‐modified alginate hydrogel microsphere‐encapsulated enzyme‐probiotic biohybrid (AKK‐COD) system has been developed to address the spatiotemporal delivery and colonization challenges of small intestine‐targeted probiotic for lipid metabolism regulation. The system exerts sequential functions of intragastric protection, small intestinal adhesion,
