  2. 1. B cell activation in vitro: thymus-dependent immune responses and bacterial cell surface proteins

    Author : Karol Axcrona; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear transport; bacterial Ig-binding proteins; CD40L promoter; CD21; Ig; B lymphocyte activation in vitro; CD40; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. READ MORE

  4. 2. Studies of pore-forming bacterial protein toxins in Escherichia coli

    Author : Constance Enow; Bernt Eric Uhlin; Sun Nyunt Wai; Mikael Rehn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylärbiologi; Molecular Biology;

    Abstract : Escherichia coli, a Gram-negative bacterium, which can be classified into three groups: the commensal, intestinal pathogenic (IPEC) and extra-intestinal pathogenic (ExPEC) E. coli. The cytolysin A (ClyA) protein, a 34-kDa pore-forming toxin, encoded by a gene found in both non-pathogenic and pathogenic E. READ MORE

  5. 3. Marker genes : molecular tools for in situ monitoring of bacterial distribution and activity in environmental samples

    Author : Annika Unge; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : Many different microorganisms carry out environmental functions, such as nutrient cycling, plant growth enhancement, or biodegradation. Some microorganisms also negatively affect their environment by causing disease. READ MORE

  6. 4. Development of bioluminescent reagents for kinetic analysis and some applications in clinical chemistry

    Author : Inger Styrélius; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Firefly luciferase and a bacterial luciferase system have been used to develop analytical methods suitable for use in clinical analysis.The influence of the level of NADH:FMN oxidoreductase on the kinetics of light emission in the bacterial luciferase system was studied. READ MORE

  7. 5. Studies of the physiological status of bacteria used for environmental applications

    Author : Ninwe Maraha; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Today, it is difficult to study the physiological status of inoculants in complex environments, such as soil. In this thesis, we describe the combined use of marker genes and viability stains to determine the physiological status of the bacterial cells in pure cultures and in soil. READ MORE
