Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Structural and Functional Siderophore Remodeling by Enzymatic Delipidation

open access: yesAngewandte Chemie, EarlyView.
A surprising functional switch in bacterial siderophores was discovered through genome mining and the analysis of environmental and pathogenic Pandoraea species. Pandorachelin B, a lipocyclopeptide that promotes swarming motility, is cleaved by a specialized acylase, yielding a ring‐contracted, homodetic cyclopeptide, pandorachelin A, which exhibits ...

Exosome‐mediated gut–brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives—A narrative review

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The gut–brain axis is a bidirectional communication network between the intestines and brain, mediated by gut microbiota and exosomes, that regulates neuroinflammation, protein aggregation, and neuronal health processes central to neurodegenerative diseases.

Environmental Identification of Novel Enzymes for Polyurethane and Polyamide Degradation

open access: yesAngewandte Chemie, EarlyView.
Heteroatom‐containing plastics such as polyurethanes and nylons are produced at scale yet remain largely unrecycled. Biocatalysts offer a promising route to depolymerization under mild conditions. Here, we present a screening platform for the discovery of novel polyurethane‐ and nylon‐degrading enzymes from environmental samples and demonstrate ...

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

open access: yesAdvanced NanoBiomed Research, EarlyView.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

Human Leukocyte Elastase Triggered Nanoparticles for Targeted Antimicrobial Delivery and Oral Microbial Modulation

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study explores enzyme‐responsive nanoparticles for targeted antimicrobial release in inflamed oral environments. Nanoparticles formed by complexing peptides and chlorhexidine respond to human leukocyte elastase and release chlorhexidine selectively. P7 (ECAAPVCE)‐based formulations show optimal properties and stability, with antimicrobial activity
