  1. 1. Roles of membrane vesicles in bacterial pathogenesis

    Author : Svitlana Vdovikova; Sun Nyunt Wai; Richard Lundmark; Ann-Beth Jonsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane vesicles; autophagy; pore-forming toxin; pore formation; Listeria monocytogenes; Vibrio cholerae; virulence factor; PrtV protease; listeriolysin O; V. cholerae cytolysin; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology;

    Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

  2. 2. Redox effects on neutrophils in wound healing conducted by wound dressings and hyperbaric oxygen

    Author : Herman Sahlin; Göteborgs universitet; []
    Keywords : neutrophil granulocyte; wound healing; wound dressing; reactive oxygen species; NO; hyperbaric oxygen; bacterial killing;

    Abstract : The increased influx of neutrophils into chronic wounds results in increased production of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation products (LPP), as well as a ROS-induced increase in protease levels. The NO and LPP impair the respiratory burst response of the neutrophils and reduce their capacity to kill bacteria and digest debris. READ MORE

  3. 3. Vaginal commensal bacteria. Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI

    Author : Louise Strömbeck; Göteborgs universitet; []
    Keywords : Prevotella bivia; bacterial vaginosis BV ; invasion; Lactobacillus; secretory leukocyte protease inhibitor SLPI ; cytokines; THP-1; HeLa cells;

    Abstract : Vaginal commensal bacteria Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI Louise Strömbeck Department of Infectious Medicine, Gothenburg University Abstract Lactobacillus is the predominant species of the vaginal microbiota in women of childbearing age. Lactobacilli are thought to contribute to the local immune defence by producing a variety of antimicrobial substances and, thereby, attenuate growth of other opportunistic bacteria. READ MORE

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

    Author : Sravya Sowdamini Nakka; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicin; Biomedicine;

    Abstract : Periodontitis is a chronic infectious disease causing inflammation and destruction of tooth-supporting structures eventually leading to tooth loss. Periodontitis is induced by different subgingival microorganisms in combination with an excessive and dysregulated immune-inflammatory response against this microbial challenge. READ MORE
