Peptidoglycan Remodeling Enables Escherichia coli To Survive Severe Outer Membrane Assembly Defect
mBio, 2019 In Gram-negative bacteria, the outer membrane protects the cell against many toxic molecules, and the peptidoglycan layer provides protection against osmotic challenges, allowing bacterial cells to survive in changing environments.

Advanced Functional Materials, EarlyView.A new class of living liquid metal composites is introduced, embedding Bacillus subtilis endospores into eutectic gallium–indium (EGaIn). The spores enhance droplet coalescence, strengthen interfacial conductivity, and provide on‐demand electrogenic functionality after germination. The composites exhibit high conductivity, self‐healing, patternability,

Prophage-triggered membrane vesicle formation through peptidoglycan damage in Bacillus subtilis
Nature Communications, 2017 Bacteria release membrane vesicles (MVs) that play important roles in various biological processes. However, the mechanisms of MV formation in Gram-positive bacteria are unclear, as these cells possess a single cytoplasmic membrane that is surrounded by ...

Advanced Healthcare Materials, EarlyView.Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

LipidII: Just Another Brick in the Wall? [PDF]
PLoS Pathogens, 2015 Nearly all bacteria contain a peptidoglycan cell wall. The peptidoglycan precursor molecule is LipidII, containing the basic peptidoglycan building block attached to a lipid.

Borrelia burgdorferi peptidoglycan is a persistent antigen in patients with Lyme arthritis
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Lyme disease, caused by the spirochete Borrelia burgdorferi, is the most common vector-borne disease in North America. If early infection is untreated, it can result in late-stage manifestations, including arthritis. Although antibiotics are

Advanced Healthcare Materials, EarlyView.A methacrylamide β‐cyclodextrin‐based nanogel (MACD nGel) is developed to load the antimicrobial drug Metronidazole (MNZ) for topical delivery for the treatment of periodontitis. It is demonstrated that cyclodextrin nanogel (nGel) loaded with metronidazole provides an efficient drug delivery route but also has potential clinical applications and offers

Advanced Healthcare Materials, EarlyView.As implantable medical devices become indispensable to modern medicine, a silent threat grows alongside them: device‐associated infections. Despite decades of antibiotic innovation, infection rates keep climbing, costing lives and billions in healthcare expenses.
