  1. 1. Too close for comfort : The role of Contact-Dependent growth Inhibition (CDI) in interbacterial competition and cooperation

    Författare :Marcus Wäneskog; Sanna Koskiniemi; Paul Rainey; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial interactions; cell-cell binding; contact-dependent growth inhibition; CDI; CdiB; CdiA; CdiI; outer-membrane receptor; BamA; OmpC; OmpF; extracellular toxin delivery; Toxin-Antitoxin; TA-system; persister cells; stress tolerance; stress response; rpoS; rssB; quorum sensing; multicellular behavior; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Contact-Dependent growth inhibition (CDI) was discovered in 2005 in the E. coli isolate EC93. Since then our knowledge of CDI systems and their impact on bacterial communities have increased exponentially. LÄS MER

  3. 2. Modulators of Vibrio cholerae predator interaction and virulence

    Författare :Barbro Lindmark; Sun Nyunt Wai; Kristian Riesbeck; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vibrio cholerae; Caenorhabditis elegans; PrtV; outer membrane vesicles; non-O1 non-O139; serum resistance; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Vibrio cholerae, the causal agent of cholera typically encodes two critical virulence factors: cholera toxin (CT), which is primarily responsible for the diarrhoeal purge, and toxin-co-regulated pilus (TCP), an essential colonisation factor. Nontoxigenic strains expressing TCP can efficiently acquire the CT gene through lysogenic conversion with CTXΦ, a filamentous phage that encodes CT and uses TCP as a receptor. LÄS MER

  4. 3. Identification and Characterization of the Moraxella catarrhalis IgD-binding Protein MID

    Författare :Andrea Möllenkvist; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; receptor; structure; phase variation; MID; IgD; Moraxella catarrhalis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Moraxella catarrhalis is now an established human pathogen that frequently colonizes the upper respiratory tract causing most importantly otitis media in children. It has also been associated with sinusitis, laryngitis and lower respiratory tract infections in adults with predisposing conditions such as chronic obstructive pulmonary disease (COPD). LÄS MER

  5. 4. Regulation of the pro-apoptotic protein Bim by T cell receptor triggering in human T cells

    Författare :Elena Sandalova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bim; Apoptosis; Mitochondria; CTLs; AICD; TCR activation;

    Sammanfattning : Bim is a significant pro-apoptotic member of Bcl-2 family of proteins; it is proved to be an important regulator of apoptosis: over the years it has been shown to play a pivotal role for the development and maintenance of homeostasis in many cellular systems and tissues. The Bcl-2 family of proteins is a group of key regulators of the mitochondrial, or intrinsic, pathway of apoptosis. LÄS MER

  7. 5. Helicobacter pylori cell surface interactions with glycosaminoglycans. Identification and characterisation of proteins binding to heparin/heparan sulphate

    Författare :Meeme Utt; Celiaki och diabetes; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SELDI-TOF MS; bioinformatics; proteomics; immunoblotting; 2-DE; biosensor; heparan sulphate; heparin; binding; Helicobacter pylori; cell surface; bakteriologi; Mikrobiologi; mycology; bacteriology; Microbiology; mykologi; virologi; virology;

    Sammanfattning : Helicobacter pylori is a gastric pathogen which cause chronic type B gastritis and peptic ulcer disease. H. pylori produces virulence factors such as urease, vacuolating cytotoxin VacA, cag pathogenicity island-associated proteins, flagella and adhesins. LÄS MER
