F‐Type Pyocin Versus Phage λ Tail: Conserved Hub, Divergent Fibers

Advanced Science, EarlyView.
Near‐atomic cryo‐EM structures of a Gram‐negative F‐type pyocin reveal a conserved tail tip architecture shared with bacteriophage λ together with a previously unrecognized side‐fiber attachment mode. These findings provide new insight into tailocin assembly and host recognition and establish a structural framework for engineering precision ...

Protease‐Triggered Chromogenic Release From Peptide‐Modified Calcium Carbonate Microspheres Enables Colorimetric Detection of Porphyromonas gingivalis Activity

Advanced Science, EarlyView.
We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...

Effects of Oral Appliance Therapy with a Mouth Shield in Periodontitis Patients Who Snore: A Split-Mouth Randomized Controlled Trial

Dentistry Journal
Background: Periodontitis is linked to sleep-disordered breathing (SDB), including snoring, with 50–75% of cases involving mouth breathing (MB). Standard treatment includes scaling and root planing (SRP).

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Programming Gut Microbiome Function Through Cross‐Feeding: From Ecological Mechanisms to Live Biotherapeutics

Advanced Science, EarlyView.
This graphical abstract presents gut microbial cross‐feeding through a Mechanism–Technology–Application framework. It summarizes major resource‐transfer modes, the experimental and computational tools used to establish causality, and potential interventions involving dietary substrates, live biotherapeutic products, and engineered microbes.

Streptococcal Mannose Phosphotransferase System Component IID Is a Novel RANK‐Binding Osteoclastogenic Factor

Advanced Science, EarlyView.
Streptococcal mannose phosphotransferase system component IID (Man‐PTSIID) is identified as a novel RANK‐binding osteoclastogenic factor. By directly binding to RANK and activating NF‐κB independently of TLR2, Man‐PTSIID drives osteoclastogenesis and inflammatory bone destruction, uncovering an unexpected microbial mechanism underlying streptococcal ...

Microbiological and molecular aspects of periodontitis pathogenesis: an infection-induced inflammatory condition

Frontiers in Cellular and Infection Microbiology
Periodontitis (PD) is the most common oral infectious disease. The primary etiologic cause of the onset and development of PD is dental plaque, which consists of bacterial biofilm domiciled within a complex extracellular mass.
