  2. 1. Modulaton of gene expression in human aortic smooth muscle cells by Porphyromonas gingivalis : a possible association between periodontitis and atherosclerosis

    Author : Boxi Zhang; Torbjörn Bengtsson; Allan Sirsjö; Hazem Khalaf; Julia Davies; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microarray; Angiopoietin; Smooth muscle cells; TNF; Periodontitis; Atherosclerosis; Porphyromonas gingivalis; Cancer; Inflammasome; Biomedicin; Biomedicine;

    Abstract : Porphyromonas gingivalis is a gram-negative, rod-shaped, and anaerobic bacterium that is involved in the pathogenesis of periodontitis. P. gingivalis produces a variety of virulence factors including gingipains and fimbriae. READ MORE

  4. 2. Development of novel tools for prevention and diagnosis of Porphyromonas gingivalis infection and periodontitis

    Author : Sravya Sowdamini Nakka; Torbjörn Bengtsson; Hazem Khalaf; Fariba Nayeri; Johanna Lönn; Tülay Lindberg; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Porphyromonas gingivalis; anti-P. gingivalis antibodies; surface plasmon resonance; PLNC8 αβ; proliferation; growth factors.; Biomedicin; Biomedicine;

    Abstract : Periodontitis is a chronic inflammatory disease caused by exaggerated host immune responses to dysregulated microbiota in dental biofilms leading to degradation of tissues and alveolar bone loss. Porphyromonas gingivalis is a major periodontal pathogen and expresses several potent virulence factors. READ MORE

  5. 3. Genotypic and phenotypic characterization of Porphyromonas gingivalis in relation to virulence

    Author : Takashi Yoshino; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Porphyromonas gingivalis; Phenotype; Genotype; Virulence; Periodontitis;

    Abstract : The present thesis was designed to increase the knowledge on the role of pathogenic potential of Porphyromonas gingivalis as a putative periodontal pathogen. P. READ MORE

  6. 4. Periodontitis in adolescents : presence of Aggregatibacter species and interactions with the host

    Author : Mark Lindholm; Jan Oscarsson; Anders Johansson; Carola Höglund-Åberg; Eija Könönen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; Aggregatibacter aphrophilus; periodontitis; adolescents; OmpA; outer membrane vesicles; serum resistance; odontologi; Odontology;

    Abstract : Aggregatibacter actinomycetemcomitans and Aggregatibacter aphrophilus are closely related gram-negative bacteria mainly found in the oral cavity. Periodontitis in adolescents is associated with the presence of A. actinomycetemcomitans, but not with the presence of A. aphrophilus. READ MORE

  7. 5. Insights into the processes preceding the onset of rheumatoid arthritis

    Author : Linda Johansson; Solbritt Rantapää Dahlqvist; Mikael Brink; Felipe Andrade; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatoid arthritis; pre-symptomatic individuals; autoantibodies; anti-citrullinated protein peptides antibodies; Epstein-barr virus; neutrophil extracellular traps; periodontitis; Porphyromonas gingivalis; receptor activator of nuclear factor kappa-B ligand; reumatologi; rheumatology;

    Abstract : Rheumatoid arthritis (RA) is a chronic inflammatory disease, characterized by the production of anti-citrullinated protein antibodies (ACPA) in the majority of all patients and a persistent inflammation in the synovial tissue leading to joint destruction. The aetiology of RA remains to a large extent unknown but is believed to be a complex interplay between genetic, environmental and stochastic factors. READ MORE
