  2. 1. Host-pathogen interactions during Campylobacter and Yersinia infections

    Author : Nayyer Taheri; Anna Fahlgren; Maria Fällman; Sun Nyunt Wai; Elena Vikström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Campylobacter jejuni; Yersinia pseudotuberculosis; OMV; bile; temperature; proteomic;

    Abstract : The innate immune system is known for protecting the host against invading pathogens, for instance enteropathogens infecting the gastrointestinal tract. The production of e.g. antimicrobial peptides, cytokines, and chemokines by innate immune cells and intestinal epithelial cells contribute to bacterial clearance. READ MORE

  4. 2. Vibrio cholerae modulates the immune defense of human gut mucosa

    Author : Aziz Bitar; Marie-Louise Hammarström; Sun Nynt Wai; Mikael Rehn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibrio cholerae; intestinal epithelial cell; duodenum biopsy; acute cholera; immunomodulation; microRNA; OMV; cytokine; T84 monolayer; miR-146; miR-155; VCC; PrtV; hemolysis; IL-8; TNF-a; IL-1b; IL-18; CCL20; IRAK2; inflammation; mikrobiologi; Microbiology; immunologi; Immunology;

    Abstract : The key function of innate immunity is to sense danger signals and initiate effective responses as a defense mechanism against pathogens. Simultaneously, effector responses must be regulated to avoid excessive inflammation with resulting tissue damage. READ MORE

  6. 4. Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance

    Author : Viveka Schaar; Malmö Klinisk mikrobiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Host-Pathogen Interactions in Pseudomonas aeruginosa Invasive and Respiratory Tract Infection

    Author : Magnus Paulsson; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pseudomonas aeruginosa; vitronectin; Respiratory tract infections; Innate Immunity; outer membrane vesicles; outer membrane proteins; beta-lactamase; ciprofloxacin; combination treatment; bacteraemia; Complement escape;

    Abstract : Pseudomonas aeruginosa is an opportunistic bacterium that causes debilitating infections when the immune defence is compromised. It possesses an arsenal of virulence traits to colonize most compartments of the body and is often highly resistant against commonly used antimicrobial drugs. READ MORE
