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

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

   Abstract : 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. READ MORE

4. 2. 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.

5. 3. Kostmann syndrome : a clinical and pathophysiological study

   Author : Göran Carlsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Kostmann syndrome; severe congenital neutropenia; autosomal recessive; periodontitis; antibacterial peptides; LL-3 7; apoptosis; Bcl-2; granulocyte colony-stimulating factor; glycosylation; lenograstim; filgrastim.;

   Abstract : Kostmann syndrome or severe congenital neutropenia (SCN) is a rare disease, usually diagnosed during the first months of life, characterized by extremely low levels of neutrophils in the peripheral blood, a maturational arrest of the myelopoiesis in the bone marrow and severe bacterial infections. The purpose of this project was to improve the understanding of the clinical course and the pathophysiology of autosomal recessive SCN. READ MORE

6. 4. Anxiety, exhaustion and depression in relation to periodontal diseases

   Author : Annsofi Johannsen; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Anxiety; stress; depression; gingival inflammation; periodontal diseases; smoking; inflammatory markers; cortisol; HPA axis;

   Abstract : Periodontal diseases (gingivitis and periodontitis), are inflammatory processes of the gingiva and supporting structures of the teeth induced by a microbial biofilm. In periodontitis this inflammatory process causes tissue degradation and eventually tooths loss. READ MORE

7. 5. 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
