  2. 1. Midkine - a host defence protein

    Author : Sara Nordin; allergologi och palliativ medicin Lungmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial polypeptides; Midkine; antibacterial; antifungal; innate immunity; epithelial surfaces;

    Abstract : Every day we encounter many potentially harmful microbes in our environment. The epithelial linings constitute an anatomical barrier protecting us and they also produce antimicrobial polypeptides (AMPs) that act as a chemical barrier. These AMPs are small and positively charged, killing a broad range of microbes rapidly. READ MORE

  4. 2. Inflammasomes : defense guardians in host-microbe defence

    Author : Berolla Sahdo; Eva Särndahl; Bo Söderquist; Anna Norrby Teglund; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Innate immunity; inflammasome; leukocytes; cytokines; Staphylococcus aureus; Propionibacterium acnes; inflammation; infection; gene variants; polymorphism.; Biomedicin; Biomedicine;

    Abstract : The inflammasomes are emerging as key regulators of the innate immune response as they response to cellular infection, tissue damage and/or stress. Activated inflammasomes provide a signalling platform for caspase-1 activation which subsequently processes the maturation of interleukin (IL)-1β and IL-18, and in addition promotes cell death, named pyroptosis.

  5. 3. Alpha-1-microglobulin: Innate defence against pathological oxidation

    Author : Magnus Gram; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-1-microglobulin; pathological oxidation; hemoglobin; heme; radiation; oxidation; ROS; hemoglobin and heme antagonist; radical scavenger;

    Abstract : Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. READ MORE

  6. 4. Functional dualism of antimicrobial host defence peptides

    Author : Åse Björstad; Göteborgs universitet; []
    Keywords : antimicrobial; apoptosis; cathelicidin; host defence peptide; interleukin 8; LL-37; permeabilisation;

    Abstract : Antimicrobial host defence peptides are central to innate immunity and many possess direct antimicrobial actions on bacteria as well as indirect immunomodulatory functions on human leukocytes. Different variants of the bifunctional Helicobacter pylori peptide, Hp(2-20), were synthesised and inhibition zone assays and chemiluminescence systems were employed for determination of direct antimicrobial action and superoxide release (immunomodulatory) from human neutrophils, respectively.

  7. 5. Microarray analyses of the small intestinal mucosa during experimental and clinical cholera

    Author : Carl-Fredrik Flach; Göteborgs universitet; []
    Keywords : Vibrio cholerae; cholera toxin; microarray; transporter; intraepithelial lymphocytes; innate defence;

    Abstract : Vibrio cholerae is a Gram-negative bacterium and the causative agent of cholera. The bacteria infect humans via contaminated water and food, and colonize the upper parts of the small intestine to cause disease. The disease is characterized by watery diarrhoea and most of its clinical features can be attributed to the secreted cholera toxin (CT). READ MORE
