LitR and its quorum-sensing regulators modulate biofilm formation by Vibrio fischeri

Journal of Bacteriology
Quorum sensing controls numerous processes ranging from the production of virulence factors to biofilm formation. Biofilms, communities of bacteria that are attached to one another and/or a surface, are common in nature, and when they form, they can ...

Interkingdom Interactions in the Gut: Ecological Mechanisms, Homeostasis, and Therapeutic Modulation

Gut Medicine, EarlyView.
ABSTRACT The gut microbiota constitutes a highly complex and dynamic ecosystem that profoundly influences host physiology, metabolism, and immunity. This review provides an integrative overview of the mechanisms through which gut microorganisms—particularly bacteria and fungi—interact with host cells and with each other to maintain intestinal ...

Functionally complementary bacterial inoculant coordinates arbuscular mycorrhizal fungi to improve Angelica sinensis root yield and quality

iMetaOmics, EarlyView.
Comprehensive understanding of how diverse PGPR strains enhance the rhizosphere microenvironment remains a considerable challenge. Here, we provide experimental evidence that a functionally synergistic composite microbial formulation can markedly enhance growth performance and improve the quality attributes in Angelica sinensis.

Achieving superior therapeutic effects on methicillin‐resistant Staphylococcus aureus infection via simple sulfonation process for preparing zwitterionic photosensitizer

Interdisciplinary Medicine, EarlyView.
The sulfonated zwitterionic photosensitizer (PYSO3) is synthesized by reacting maleic anhydride derivatives with 4‐aminopyridine to form PY, followed by sulfonation with 1,4‐butane sultone. It exhibits both photothermal and photodynamic properties, enabling effective eradication of MRSA and biofilms, as well as promoting wound healing in mice ...

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Dextran sodium sulfate confounds causal role of periodontitis in inflammatory bowel disease

Journal of Periodontology, EarlyView.
Abstract Background Emerging evidence supports a bidirectional link between periodontitis and inflammatory bowel disease (IBD). To investigate this relationship, experimental models commonly use dextran sodium sulfate (DSS) to induce colitis. However, DSS is presumed to selectively affect the colon, and its potential off‐target effects on the oral ...

Bacterial quorum sensing

The FASEB Journal, 2009
Bacteria sense and respond to small molecule signals in a cell‐cell communication process termed quorum sensing. We are investigating recently identified quorum sensing circuits in several different bacterial species.

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Genome‐wide screen reveals a universal role of ATP in ciprofloxacin tolerance among genetically distinct Escherichia coli persisters

mLife, EarlyView.
Abstract Bacterial persisters show tolerance to bactericidal antibiotics and play essential roles in chronic infections; however, the general mechanisms underlying persister formation and antibiotic tolerance remain insufficiently characterized. In this study, the Escherichia coli Keio library was used to identify genes involved in ciprofloxacin ...
