Pronthocyanidin-Rich Cranberry-FractionInduced Alteration of Periodontal Pathogen Lipopolysaccharide Functions
… of urinary tract colonization by bacterial pathogens. The proanthocyanidin rich cranberry fraction has long been speculated to possess the capacity to reduce the production of inflammatory mediators by LPSstimulated macrophages and gingival fibroblasts and to inhibit host extracellular …

Activity of Epithelial Defensin HBD-3 Against a Periodontal Pathogen
… anaerobic bacteria that are associated with periodontal disease are resistant to human α-defensins, but are killed by β-defensins. </p> <p> HBD-3 is the most active β-defensin. HBD-3 is a longer peptide than HNP 1-4. HBD-3 has additional amino acid residues with hydrophobic side chains near …

LPS from subgingival plaque and the periodontal pathogen Porphyromonas gingivalis, its effect on M1 and M2 macrophage responses and potential as a biomarker
… may also confer protective benefits to potential pathogens. Several bacteria, including keystone periopathogen Porphyromonas gingivalis (PG) is able to modify the bio-reactive lipid-A portion of LPS which in turn modifies immune response. The aims of this study were to characterise lipid-A …

Species-specific DNA probes for the identification of Actinobacillus actinomycetemcomitans
… was developed for the identification of the periodontal pathogen, Actinobacillus actinomycetemcomitans. Chromosomal DNA was extracted from A. actinomycetemcomitans, digested with a restriction enzyme, Sau3A, ligated to plasmid DNA (pUC18) and transformed into JM109 cells to give a partial A. …

Oral epithelium in the pathogenesis of periodontitis
… line (H400) in order to investigate responses to periodontal pathogen stimulation (P. gingivalis and F. nucleatum) in terms of NF-\(\kappa\)B activation, differential gene expression and cytokine production. The pathogenesis of periodontitis suggests that susceptible patients exhibit a …

The Role of Collagen Interacting Proteins in the Pathogenesis of Filifactor alocis
… anaerobe that has emerged as a potential periodontal pathogen due to its presence in high numbers in patients who have periodontal disease and least detection in healthy individuals (Kumar et al., 2003, Kumar et al., 2006, Wade, 2011). There is compelling evidence in the literature that …

Mechanisms of Virulence Regulation in Porphyromonas gingivalis W83
… the gingipains, are responsible for pathogenesis including degradation of complement and immunoglobulin, inactivation of cytokines and their receptors, aggregation of platelets, attenuation of neutrophil antibacterial activities, and increase in vascular permeability and blood …

Antimicrobial Activity of Human Leukocyte Defensin HNP-4 Against Gram-negative Bacteria
… actinomycetemcomitans (A.a.) and other periodontal pathogens are gram-negative. These bacteria are resistant to HNP 1-3. Defensin-resistance may contribute to the ability of these bacteria to cause disease. There have been no studies of HNP-4 activity against oral bacteria, because HNP-4 …

Aetiological links between oral pathogens and dementia.
… studies support an association between periodontal disease and Alzheimer’s disease (AD). Poorly managed oral hygiene together with the immunosuppressed status of demented patients appears central to this hypothesis as together they contribute not only to an increased incidence of oral …
