Microbial Changes in Subgingival Plaque and Polymicrobial Intracellular Flora in Buccal Cells after Fixed Orthodontic Appliance Therapy: A Preliminary Study

International Journal of Dentistry, 2013
The oral ecosystem is strictly related to a balance maintained by specific niches recognized as sites, where oral bacteria can metabolize avoiding the immune system response. The oral bacteria species that colonize the ecological niches vary during fixed

PERIODONTOPHATOGENIC BACTERIA OF THE MAIN FACTORS OF EMERGENCE AND DEVELOPMENT OF PERIODONTITIS

Журнал микробиологии, эпидемиологии и иммунобиологии, 2017
Presents a modern understanding of the role of periodontophatogenic bacteria types: Aggregatibacter actinomycetemcomitans (Actinobacillus actinomycetemcomitans), Tannerella forsythia (Bacteroides forsythus) and Porphyromonas gingivalis as indicators of ...

Identification of OmpA-Like Protein of Tannerella forsythia as an O-Linked Glycoprotein and Its Binding Capability to Lectins. [PDF]

PLoS ONE, 2016
Bacterial glycoproteins are associated with physiological and pathogenic functions of bacteria. It remains unclear whether bacterial glycoproteins can bind to specific classes of lectins expressed on host cells.

Identification of a Novel N -Acetylmuramic Acid Transporter in Tannerella forsythia [PDF]

Journal of Bacteriology, 2016
ABSTRACT Tannerella forsythia is a Gram-negative periodontal pathogen lacking the ability to undergo de novo synthesis of amino sugars N -acetylmuramic acid (MurNAc) and N -acetylglucosamine (GlcNAc) that form the disaccharide repeating unit of ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

The contribution of Tannerella forsythia dipeptidyl aminopeptidase IV in the breakdown of collagen. [PDF]

Mol Oral Microbiol, 2018
SummaryIn this study, we characterized a serine protease from Tannerella forsythia that degrades gelatin, type I, and III collagen. Tannerella forsythia is associated with periodontitis progression and severity. The primary goal of this research was to understand the mechanisms by which T. forsythia contributes to periodontitis progression.

Autoimmunity and Periodontitis

Journal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

Red-complex bacteria: immunological background leading to the development of head and neck cancers

Frontiers in Immunology
Oral microbiome imbalance is involved in the development of head and neck cancers (HNCs). There is a group of oral pathogens, such as Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola, that creates red-complex.
