  2. 16. Uptake and fate of pathogenic microbes in the blue mussel, Mytilus edulis

    Author : Bodil Hernroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mytilus edulis; bivalve; immune response; lipopolysaccharide; LPS; antimicrobial peptide; gamma camera; radiolabelling; Salmonella typhimurium; sanitary safety; public health;

    Abstract : Bivalves, like the blue mussel Mytilus edulis, are filter-feeders and can therefore accumulate high numbers of microbes from the surrounding water. These shellfish are considered the main risk for bringing pathogens from domestic outlets in the sea, back to the community. READ MORE

  4. 17. Bacterial epithelial interaction in intestinal inflammation

    Author : Lina Yakymenko Alkaissi; Åsa Keita; Johan D Söderholm; Maria Magnusson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The intestine is constantly exposed to bacteria, invading viruses and ingested food. The intestinal barrier serves as a gate preventing passage of harmful components, and at the same time maintaining absorption of nutrients and water. READ MORE

  5. 18. Nora virus as a model to study persistent infection in Drosophila melanogaster

    Author : Mazen Habayeb; Dan Hultmark; Joachim De Miranda; Molecular Biology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nora virus; Drosophial; persistence; transmission; RNAi; capsid proteins; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; molekylärbiologi; Molecular Biology;

    Abstract : Drosophila melanogaster has been widely used as a model organism to study the immune responses against bacteria, fungi, parasites and viruses. Here, I present a D. melanogaster virus as a model to study persistent virus infections. I have discovered and characterized the Nora virus, a small picorna-like RNA virus able to persistently infect D. READ MORE

  6. 19. Design, Fabrication and Testing of Functional Single Pores for Bio-Detection Applications

    Author : Joakim Nilsson; Reinhold Schuch; Sonia Letant; Nigel Mason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Chemically functionalized and size-tunable apertures constitute a platform of choice for bio-organism sensing. Apertures were fabricated on pre-patterned silicon platforms using focused ion beam (FIB) drilling, followed by local oxide (TEOS) deposition. READ MORE

  7. 20. Human dendritic cells in blood and airways during respiratory viral infection

    Author : Faezzah Baharom; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The air we inhale contains oxygen necessary for life, but also potentially harmful microorganisms, toxins and allergens. This presents an important immunological dilemma: how can our lungs quickly and selectively eliminate harmful agents without inflicting damage on the delicate tissues of the lungs? We have thus evolved a network of cells involved in immune surveillance, made up of dendritic cells (DCs), monocytes and macrophages. READ MORE
