Research progress on the mechanisms by which plant-originated quorum sensing inhibitors inhibit pathogenic bacteria of acne

Pifu-xingbing zhenliaoxue zazhi
The main acne-causing bacteria are Propionibacterium acnes, Staphylococcus aureus and Staphylococcus epidermidis. Quorum sensing, an important factor for bacterial survival, is closely associated with expression of bacterial virulence factors and biofilm

The AHL Quorum-Sensing System Negatively Regulates Growth and Autolysis in Lysobacter brunescens

Frontiers in Microbiology, 2019
Lysobacter species are emerging as novel sources of antibiotics, but the regulation of their physiological metabolism is still poorly understood. In this work, we extracted AHL (acyl-homoserine lactone) autoinducers, identified the structures of AHLs and

Evolving quorum sensing in digital organisms [PDF]

, 2009
For centuries it was thought that bacteria live asocial lives. However, recent discoveries show many species of bacteria communicate in order to perform tasks previously thought to be limited to multicellular organisms.

Targeted Intervention Strategies for Maternal–Offspring Transmission of Christensenellaceae in Pigs via a Deep Learning Model

Advanced Science, EarlyView.
This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Interference of bacterial cell-to-cell communication: A new concept of antimicrobial chemotherapy breaks antibiotic

Frontiers in Microbiology, 2013
Bacteria use a cell-to-cell communication activity termed Quorum sensing to coordinate group behaviors in a cell-density dependent manner. Quorum sensing influences the expression profile of diverse genes, including antibiotic tolerance and virulence ...

Cellular Adaptation to Mechanical Stress Emerges via Cell Shrinkage Triggered by Nonlinear Calcium Elevation

Advanced Science, EarlyView.
Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

The phenazine pyocyanin is a terminal signalling factor in the quorum sensing network of Pseudomonas aeruginosa [PDF]

, 2006
Certain members of the fluorescent pseudomonads produce and secrete phenazines. These heterocyclic, redox-active compounds are toxic to competing organisms, and the cause of these antibiotic effects has been the focus of intense research efforts.

Brachyury‐Activated Fucoidan Hydrogel Microspheres Rejuvenate Degenerative Intervertebral Discs Microenvironment

Advanced Science, EarlyView.
This study describes the creation of injectable Brachyury (Bry) mRNA‐loaded Fucoidan‐functionalized GelMA hydrogel microspheres (BLNP@GF). These microspheres efficiently suppress inflammation, enhance extracellular matrix (ECM) synthesis in degenerated nucleus pulposus cells, and mitigate intervertebral disc degeneration (IVDD) in rat models.
