  1. 1. Outer membrane proteins of Yersinia pestis : Ail and OmpA

    Författare :Sara Celinda Schesser Bartra; Hans Wolf-Watz; Virginia Miller; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pestis; outer membrane proteins; Ail; ompA; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; immunologi; Immunology; mikrobiologi; Microbiology; Infectious Diseases; infektionssjukdomar;

    Sammanfattning : A vast number of studies have been completed on the virulence determinants of Yersinia spp.; however, the focus of many of these studies has been on the virulence plasmid and the plasmid-encoded Type three secretion system. Nevertheless, many chromosomal genes whose products are directly involved in virulence have also been identified. LÄS MER

  2. 2. Interaction of Calcium Ions with Lipid Membranes

    Författare :Baharan Ali Doosti; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Sammanfattning : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  3. 3. Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance

    Författare :Viveka Schaar; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antibiotic resistance; Moraxella catarrhalis; epithelial cells; beta-lactamase; non-typeable Haemophilus influenzae; outer membrane vesicles; polymicrobial infections; UspA1;

    Sammanfattning : Outer membrane vesicles (OMV) have the size of nanoparticles and are released from the outer membrane of most Gram-negative bacteria. The OMV reflect the composition of the bacterial outer membrane, including lipids and virulence factors specific for the pathogen, and are involved in pathogenesis and bacterial survival. LÄS MER

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

    Författare :Pramod Kumar Rompikuntal; Sun Nyunt Wai; Ann-Beth Jonsson; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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
