Inflammatory and Immunological Basis of Periodontal Diseases
Journal of Periodontal Research, EarlyView.The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

Mechanism of Vibrio cholerae Autoinducer-1 Biosynthesis
ACS Chemical Biology, 2011 Vibrio cholerae, the causative agent of the disease cholera, uses a cell to cell communication process called quorum sensing to control biofilm formation and virulence factor production. The major V. cholerae quorum-sensing signal CAI-1 has been identified as (S)-3-hydroxytridecan-4-one, and the CqsA protein is required for CAI-1 production.

The lux autoinducer-receptor interaction in Vibrio harveyi: binding parameters and structural requirements for the autoinducer [PDF]
Biochemical Journal, 1995 To assess the binding parameters and the structure-function relationship of the Vibrio harveyi lux autoinducer, N-(D-3-hydroxybutanoyl)homoserine lactone (D-HBHL), to light emission, a series of acylhomoserine lactone analogues were synthesized and their effects on the stimulation of luminescence of an autoinducer-deficient mutant of V.

, 2016 Bacteria communicate using external chemical signals called autoinducers (AI) in a process known as quorum sensing (QS). QS efficiency is reduced by both limitations of AI diffusion and potential interference from neighboring strains.

MicrobiologyOpen, Volume 15, Issue 2, April 2026.The study prepared Cinnamaldehyde‐Carvacrol nanoemulsions (CA/CV NEs) through high‐energy emulsification. In a mouse infection model, CA/CV NEs exhibited a synergistic inhibitory effect on the formation of Staphylococcus aureus–Escherichia coli mixed biofilms, reducing PIA, LuxS/AI‐2, adhesion, athletic ability, and extracellular protein.

Molecular radio jamming: autoinducer analogs.
Chemistry & biology, 2003 Synthesis of an N-acyl-homoserine lactone (N-acyl-HSL) analog library yields agonists and antagonists of the Pseudomonas aeruginosa quorum-sensing system. Active compounds also reveal heterogeneity in the lactone ring binding pockets of N-acyl-HSL-activated transcription factors.

Asymmetric regulation of quorum-sensing receptors drives autoinducer-specific gene expression programs in Vibrio cholerae. [PDF]
PLoS Genetics, 2017 Quorum sensing (QS) is a mechanism of chemical communication that bacteria use to monitor cell-population density and coordinate group behaviors. QS relies on the production, detection, and group-wide response to extracellular signal molecules called ...

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...
