  2. 1. Exotoxins of Aggregatibacter actinomycetemcomitans and periodontal attachment loss in adolescents

    Author : Carola Höglund Åberg; Anders Johansson; Rolf Claesson; Dorte Haubek; Andrea Mombelli; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; periodontal attachment loss; JP2 genotype; non-JP2 genotype; LtxA; Cdt; Infectious Diseases; infektionssjukdomar;

    Abstract : Aggregatibacter actinomycetemcomitans is an oral bacterium that is mainly associated with aggressive forms of periodontitis, which most often starts at an early age. Amongst the virulence factors of A. READ MORE

  4. 2. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Author : Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Abstract : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. READ MORE

  5. 3. Vesicle-independent extracellular release and bioactivity of peptidoglycan-associated lipoprotein from Aggregatibacter actinomycetemcomitans

    Author : Maribasappa Karched; Sirkka Asikainen; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptidoglycan-associated lipoprotein; outer membrane proteins; immunoproteomics; periodontitis; cytokines; Aggregatibacter actinomycetemcomitans.; Oral microbiology; Oral mikrobiologi;

    Abstract : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a Gram-negative coccobacillus of the Pasteurellaceae family. It is implicated in periodontitis, a common low-grade bacterial infection, but it can also cause non-oral infections. The main aim of this project was to identify and characterize in A. READ MORE

  6. 4. Cellular and molecular responses of periodontal connective tissue cells to Actinobacillus actinomycetemcomitans cytolethal distending toxin

    Author : Georgios N. Belibasakis; Sotirios Kalfas; Ulf H. Lerner; Anders Johansson; Veli-Jukka Uitto; Umeå universitet; []
    Keywords : Medical sciences; Actinobacillus actinomycetemcomitans; cytolethal distending toxin; periodontal connective tissue cells; localized aggressive periodontitis; growth arrest; bone resorption; receptor activator of NF-κB ligand; osteoprotegerin; pro-inflammatory cytokines; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; odontologi; Odontology;

    Abstract : Actinobacillus actinomycetemcomitans is present in elevated proportions and numbers in dental bacterial biofilms of patients with localized aggressive periodontitis. This variant of periodontal disease, occurring in adolescents and young adults, is characterized by rapid and severe destruction of the connective tissues and bone supporting the teeth, eventually culminating in tooth loss.

  7. 5. 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
