2. 1. Roles of membrane vesicles in bacterial pathogenesis

   Author : Svitlana Vdovikova; Sun Nyunt Wai; Richard Lundmark; Ann-Beth Jonsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane vesicles; autophagy; pore-forming toxin; pore formation; Listeria monocytogenes; Vibrio cholerae; virulence factor; PrtV protease; listeriolysin O; V. cholerae cytolysin; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology;

   Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

4. 2. Mast cells in bacterial infections

   Author : Elin Rönnberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Mast cells are implicated in immunity towards bacterial infection, but the molecular mechanisms by which mast cells contribute to the host response are only partially understood. Previous studies have examined how mast cells react to purified bacterial cell wall components, such as peptidoglycan and lipopolysaccharide. READ MORE

5. 3. Characterisation of the Clp Proteins in Arabidopsis thaliana

   Author : Bo Zheng; Adrian K. Clarke; Vaughan Hurry; Cecilia Sundby-Emanuelsson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Arabidopsis; molecular chaperone; protein degradation; protease; Clp Hsp100; ClpP; stress response; antisense repression; chloroplast development; Växtfysiologi; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

   Abstract : Unlike in the greenhouse, plants need to cope with many environmental stresses under natural conditions. Among these conditions are drought, waterlogging, excessive or too little light, high or low temperatures, UV irradiation, high soil salinity, and nutrient deficiency. READ MORE

6. 4. Vaginal commensal bacteria. Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI

   Author : Louise Strömbeck; Göteborgs universitet; []
   Keywords : Prevotella bivia; bacterial vaginosis BV ; invasion; Lactobacillus; secretory leukocyte protease inhibitor SLPI ; cytokines; THP-1; HeLa cells;

   Abstract : Vaginal commensal bacteria Interactions with cervix epithelial and monocytic cells and influence on cytokines and secretory leukocyte protease inhibitor, SLPI Louise Strömbeck Department of Infectious Medicine, Gothenburg University Abstract Lactobacillus is the predominant species of the vaginal microbiota in women of childbearing age. Lactobacilli are thought to contribute to the local immune defence by producing a variety of antimicrobial substances and, thereby, attenuate growth of other opportunistic bacteria. READ MORE

7. 5. Effects of Vibrio cholerae protease and pigment production on environmental survival and host interaction

   Author : Karolis Vaitkevicius; Sun Nyunt Wai; Timo Korhonen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria-host interaction; Nematode; Metalloprotease; Medical microbiology; Medicinsk mikrobiologi;

   Abstract : Only two out of more than 200 V. cholerae serogroups, classified on the basis of LPS structure, are associated with epidemic or pandemic cholera. These toxigenic serogroups carry phage-derived pathogenicity islands coding for the main virulence factors for establishment of cholera disease – cholera toxin (CTX) and toxin-coregulated pilus (TCP).
