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

    Detta är en avhandling från Umeå : Odontologi

    Författare :Maribasappa Karched; Sirkka Asikainen; Ann-Beth Jonsson; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peptidoglycan-associated lipoprotein; outer membrane proteins; immunoproteomics; periodontitis; cytokines; Aggregatibacter actinomycetemcomitans.; ODONTOLOGY Oral microbiology; ODONTOLOGI Oral mikrobiologi;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Umeå : Institutionen för odontologi

    Författare :Peyman Kelk; Anders Johansson; Charels A Dinarello; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : 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. LÄS MER

  3. 3. Vesicle-mediated and free soluble delivery of bacterial effector proteins by oral and systemic pathogens

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Bernard Thay; Jan Oscarsson; Mikael Rhen; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Periodontitis; Aggregatibacter actinomycetemcomitans; Staphylococcus aureus; membrane vesicles; vesicle-host cell interaction; protein delivery; molekylärbiologi; Molecular Biology;

    Sammanfattning : Periodontitis, the primary cause of tooth-loss worldwide, is a bacterially induced chronic inflammatory disease of the periodontium. It is associated with systemic conditions such as cardiovascular disease (CVD). However, pathogenic mechanisms of periodontitis-associated bacteria that may contribute to the CVD association are unclear. LÄS MER

  4. 4. Outer membrane vesicle-mediated export of virulence factors from Gram-negative bacteria

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Pramod Kumar Rompikuntal; Sun Nyunt Wai; Ann-Beth Jonsson; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Outer membrane vesicles; CDT; PGN; PrtV; Campylobacter jejuni; Vibrio cholerae; Aggregatibacter actinomycetemcomitans; molekylärbiologi; Molecular Biology;

    Sammanfattning : The Gram-negative, motile bacterium Campylobacter jejuni is a causative agent of food-borne gastroenteritis. Cytolethal distending toxin (CDT) is one of the important virulence factors for C. jejuni pathogenesis. It was not previously known how CDT is released from C. LÄS MER

  5. 5. Molecular analysis of the oral microbiota of dental diseases

    Detta är en avhandling från Umeå : Odontologi

    Författare :Eleni Kanasi; Sirkka Asikainen; Anne CR Tanner; Ingegerd Johansson; Gunnar Dahlén; [2008]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early childhood caries; early periodontitis; 16S rDNA cloning and sequencing; whole genomic DNA probes; oligonucleotide DNA probes; PCR; diversity; molecular; aggregatibacter actinomycetemcomitans; serotypes; ODONTOLOGY Oral microbiology; ODONTOLOGI Oral mikrobiologi;

    Sammanfattning : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. LÄS MER
