  2. 11. Temperature-inducible and calcium-regulated proteins encoded by the virulence plasmid of Yersinia

    Author : Ingrid Bölin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; virulence plasmid; gene products; regulation; calcium; temperature; outer membrane proteins;

    Abstract : The pathogenic members of the genus Yersinia, Y. pseudotuberculosis, Y. pestis and Y. enterocolitica are transmitted from animals to man and may give rise to disease with a variety of symptoms. READ MORE

  4. 12. Molecular mechanisms of Yersinia pseudotuberculosis for adaptation and establishment of infection in host tissue

    Author : A. K. M. Firoj Mahmud; Maria Fällman; Matthew S. Francis; Javier Pizarro-Cerda; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RpoN; T3SS; RNA-Seq; Biofilm; Transcription; Yersinia; Data analysis; ChIP-Seq; biology; biologi;

    Abstract : Bacterial pathogens can evade the host’s immune defence to adapt and establish an infection within the host. Some even slip into a quiescent state to establish themselves without acutely harming the host. Phylogenetically unrelated bacteria can share similar strategies for the establishment of infection and for persistence. READ MORE

  5. 13. Outer membrane proteins of Yersinia pestis : Ail and OmpA

    Author : Sara Celinda Schesser Bartra; Hans Wolf-Watz; Virginia Miller; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pestis; outer membrane proteins; Ail; ompA; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; immunologi; Immunology; mikrobiologi; Microbiology; Infectious Diseases; infektionssjukdomar;

    Abstract : A vast number of studies have been completed on the virulence determinants of Yersinia spp.; however, the focus of many of these studies has been on the virulence plasmid and the plasmid-encoded Type three secretion system. Nevertheless, many chromosomal genes whose products are directly involved in virulence have also been identified. READ MORE

  6. 14. Effects of invasin and YopH of Yersinia pseudotuberculosis on host cell signaling

    Author : Anna Gustavsson; Maria Fällman; Arnoud Sonnenberg; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; β1-integrin; Yersinia pseudotuberculosis; Invasin; YopH; Cell-Matrix Adhesion; Filopodia; Cell Spreading; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Integrins are a large family of membrane-spanning heterodimeric (αβ) receptors that bind to ligands on other cells or to extracellular matrix (ECM) proteins. These receptors mediate bidirectional signaling over the cell membrane to induce signaling cascades mediating functions as cell adhesion, spreading and migration. READ MORE

  7. 15. Studies of two Yersinia proteins: YopJ, an inhibitor of inflammatory responses, and YpkA, a RhoA/Rac-binding kinase

    Author : Jean-Marie Dukuzumuremyi; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serologi; transplantation; serology; Immunology; CIB; AvrA; Yops; Rac; RhoA; YpkA; Yersinia; YopJ; Immunologi;

    Abstract : Eukaryotic cells possess sensitive systems for the detection of microbes and microbial-derived products. Bacteria-eukaryotic cells contact triggers several signaling pathways, most of which are dependent on protein-protein interactions followed by phosphorylation, leading to activation of defense mechanisms.
