Pseudomonas fuscovaginae quorum sensing studies: 5% dominates cell-to-cell conversations
Microbiology SpectrumA common feature of N-acyl-l-homoserine lactone (AHL) quorum-sensing (QS) systems is that the AHL signal is autoinducing. Once induced, a cell will further amplify the signal via a positive feedback loop.

mLife, Volume 4, Issue 6, Page 623-637, December 2025.Abstract Diffusible signal factor (DSF)‐family quorum sensing (QS) signals are widely utilized by many pathogenic bacteria to modulate various biological functions and virulence. Previous studies showed that cis‐2‐decenoic acid (cis‐DA) is involved in the modulation of biofilm dispersion in Pseudomonas aeruginosa, but the regulatory mechanism is ...
