Structural and functional studies of Porphyromonas gingivalis fimbrial proteins

Journal of Oral Microbiology, 2017
Porphyromonas gingivalis expresses two forms of fimbriae, FimA and Mfa1. Each fimbria consists of five proteins; FimA-E and Mfa1-5. While the assembly of the type-1 fimbriae from Escherichia coli is well studied; the chaperone-usher pathway, very little ...

Cryptococcus gattii in AIDS Patients, Southern California

Emerging Infectious Diseases, 2005
Cryptococcus isolates from AIDS patients in southern California were characterized by molecular analyses. Pheromone MFα1 and MFa1 gene fragments were polymerase chain reaction–amplified with fluorescently labeled primers and analyzed by capillary ...

Novel and emerging antimicrobial strategies in the management of oral infections

Periodontology 2000, EarlyView.
Abstract Background Antibiotics marked a pivotal turning point in human civilization, enhancing social interactions and extending human life expectancy. In addition to their success in treating systemic infectious diseases, they have significantly improved periodontal treatment outcomes as an adjunct therapy.

Fimbriae‐Targeted Peptide‐Selenoviologen Cyclophane Complex for Enhanced Photodynamic Therapy of Periodontitis

Aggregate, Volume 6, Issue 12, December 2025.
This study develops a supramolecular photosensitizer (SeVB⊃PQ) by combining SeVB with a P. gingivalis‐targeting peptide. SeVB⊃PQ selectively binds P. gingivalis, boosts ROS generation under irradiation, disrupts ATP synthesis, restores microbial balance, reduces inflammation, and promotes alveolar bone regeneration, offering a promising platform for ...

Saccharomyces cerevisiae Mub1, a substrate adaptor of E3 ubiquitin ligase Ubr2, modulates sensitivity to cell wall stressors through multiple transcription factors

The FEBS Journal, Volume 292, Issue 19, Page 5046-5066, October 2025.
We show that Mub1 links cell wall robustness with the ubiquitin‐proteasome system. As an adaptor protein of the E3 ubiquitin ligase Ubr2, it facilitates the ubiquitination of various transcription factors, including Mcm1 and Swi4. Yeasts evolved a complex regulatory programme to build and maintain their cell wall, the primary structure through which ...

Fluoroacetate in plants - a review of its distribution, toxicity to livestock and microbial detoxification

Journal of Animal Science and Biotechnology, 2017
Fluoroacetate producing plants grow worldwide and it is believed they produce this toxic compound as a defence mechanism against grazing by herbivores. Ingestion by livestock often results in fatal poisonings, which causes significant economic problems ...

PorA of the Type IX Secretion Is a Ligand of the PorXY Two‐Component Regulatory System in Porphyromonas gingivalis

Molecular Microbiology, Volume 123, Issue 6, Page 569-585, June 2025.
Porphyromonas gingivalis exports several virulent proteins, including gingipain proteinases, via the type 9 secretion system. Expression of several T9SS component proteins is regulated by the PorA‐PorY‐PoX‐SigP signaling cascade. This study presents a novel role of PorA in the signaling cascade.

Suppressive Effects of Kouboku on Methyl Mercaptan Production and Biofilm Formation in Porphyromonas gingivalis

Molecular Oral Microbiology, Volume 40, Issue 3, Page 128-136, June 2025.
ABSTRACT Porphyromonas gingivalis, the bacterium responsible for periodontitis, produces several pathogenic factors, including methyl mercaptan, which contribute to the disease. Kouboku (Magnoliaceae), a Chinese herbal medicine, has been shown to suppress methyl mercaptan production from P. gingivalis.

Assessment and classification of different ashes from waste incinerators in Thailand

Results in Engineering
Rapid urbanisation and a growing population have led to a huge production of solid waste worldwide. To mitigate solid wastes, Thailand adapts incineration. As a consequence, a variety of fly ashes being produced in large quantities. Fly ash management is

Role of CRISPR‐Cas systems in periodontal disease pathogenesis and potential for periodontal therapy: A review

Molecular Oral Microbiology, Volume 40, Issue 1, Page 1-16, February 2025.
Abstract Clustered regularly interspaced short palindromic repeats (CRISPRs) are DNA sequences capable of editing a host genome sequence. CRISPR and its specific CRISPR‐associated (Cas) protein complexes have been adapted for various applications. These include activating or inhibiting specific genetic sequences or acting as molecular scissors to cut ...
