Engineering Cellular Self‐Adhesions Inside 3D Printed Micro‐Arches to Enhance Cell:Biomaterial Attachment

Advanced Materials, EarlyView.
Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

VSL#3 Probiotic Upregulates Intestinal Mucosal Alkaline Sphingomyelinase and Reduces Inflammation

Canadian Journal of Gastroenterology, 2008
BACKGROUND: Alkaline sphingomyelinase, an enzyme found exclusively in bile and the intestinal brush border, hydrolyzes sphingomyelin into ceramide, sphingosine and sphingosine-1-phosphate, thereby inducing epithelial apoptosis. Reduced levels of alkaline

Bifidobacterium Infantis 35624 Protects Against Salmonella-Induced Reductions in Digestive Enzyme Activity in Mice by Attenuation of the Host Inflammatory Response [PDF]

, 2012
OBJECTIVES: Salmonella-induced damage to the small intestine may decrease the villi-associated enzyme activity, causing malabsorption of nutrients and diarrhea, and thus contribute to the symptoms of infection.

Fluoroether Design Enables High‐Voltage All‐Solid‐State Lithium Metal Batteries

Advanced Materials, EarlyView.
A durable high‐voltage all‐solid‐state electrolyte is developed by incorporating a novel organic/inorganic hybrid porous component with a fluoroether design. Due to the weakened Li+ coordination structure, the proposed high‐voltage SSE exhibits durable antioxidation.

Loss of MYO5B in Mice Recapitulates Microvillus Inclusion Disease and Reveals an Apical Trafficking Pathway Distinct to Neonatal DuodenumSummary

Cellular and Molecular Gastroenterology and Hepatology, 2016
Background & Aims: Inactivating mutations in myosin Vb (MYO5B) cause severe neonatal diarrhea in microvillus inclusion disease. Loss of active MYO5B causes the formation of pathognomonic inclusions and aberrations in brush-border enzymes.

Psychological stress impairs Na+-dependent glucose absorption and increases GLUT2 expression in the rat jejunal brush-border membrane.

American Journal of Physiology. Regulatory Integrative and Comparative Physiology, 2007
Chronic psychological stress impacts many functions of the gastrointestinal tract. However, the effect of stress on nutrient absorption is poorly documented.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Moving Encounters: Actin Treadmilling in the Brush Border [PDF]

Developmental Cell, 2019
In this issue of Developmental Cell, Meenderink et al. (2019) describe how treadmilling of the actin core of nascent microvilli on the apical surface of epithelial cells underlies their motility across the cell surface, collision with each other, and ultimately clustering to form the "brush border."

Functionalized Antifouling Polymer Brushes for Biospecific Surfaces

Advanced Materials Interfaces, EarlyView.
Modern biosensors offer high sensitivity but often struggle with long‐term stability and selectivity for specific targets. Antifouling polymer brushes help enhance both stability and selectivity. In this review, we compare recent antifouling coatings, their design parameters, and how they are integrated with biorecognition elements for improved ...
