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.

Autoinducer-2 Production in Campylobacter jejuni Contributes to Chicken Colonization [PDF]

Applied and Environmental Microbiology, 2009
ABSTRACT Inactivation of luxS , encoding an AI-2 biosynthesis enzyme, in Campylobacter jejuni strain 81-176 significantly reduced colonization of the chick lower gastrointestinal tract, chemotaxis toward organic acids, and in vitro adherence to LMH chicken hepatoma cells. Thus, AI-2

Autoinducer 2: a concentration‐dependent signal for mutualistic bacterial biofilm growth [PDF]

Molecular Microbiology, 2006
Summary4,5‐dihydroxy‐2,3‐pentanedione (DPD), a product of the LuxS enzyme in the catabolism of S‐ribosylhomocysteine, spontaneously cyclizes to form autoinducer 2 (AI‐2). AI‐2 is proposed to be a universal signal molecule mediating interspecies communication among bacteria.

Asymmetric autoinducer thresholds drive distinct intragenus and interspecies QS responses.

, 2019
(A) CAI-1 produced by V. cholerae engages its cognate CqsS receptor at very low cell densities. In contrast, AI-2 does not accumulate to sufficient levels to engage its cognate LuxPQ receptor until much higher cell densities.

Relay Architectures and Ecological Strategies of Quorum Sensing Effects on Microbial Interactions

Environmental Microbiology, Volume 28, Issue 10, October 2026.
Quorum‐sensing activity in one population affects neighbouring populations through direct signal perception, QS‐regulated chemical effectors, or host‐ or environment‐mediated relays. Across distinct habitats, these relay architectures are associated with ecological strategies ranging from shared signal accessibility and reciprocal responsiveness to ...

Genomic and Phenotypic Classification of Staphylococcus Species Isolated From Delhi Air

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Multiple Staphylococcus spp. were isolated from the outdoor polluted air of the Indian Capital, New Delhi. The bacterial samples were collected from 6 different locations, and the whole genome of four Staphylococcus isolates was sequenced in their entirety. This study presents the comparative genomic analysis of these four isolates.

Discovery of novel autoinducer-2 receptors [PDF]

, 2019
"Quorum sensing is a bacterial cell-cell communication mechanism mediated by the production and detection of small chemical molecules named autoinducers. This communication mechanism allows bacteria to regulate group behaviors, through synchronization

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.
