  1. 1. YopD translocator function in Yersinia pseudotuberculosis type III secretion

    Författare :Tiago R. D. Costa; Matthew S. Francis; William D. Picking; Umeå universitet; []
    Nyckelord :Y. pseudotuberculosis; T3SS; translocon; YopD; coiled-coil; effector delivery; regulation; virulence; mikrobiologi; Microbiology;

    Sammanfattning : Type III secretion systems (T3SS) are a common feature of Gram-negative bacteria, allowing them to inject anti-host effectors into the interior of infected eukaryotic cells. By this mechanism, these virulence factors help the bacteria to modulate eukaryotic cell function in its favor and subvert host innate immunity. LÄS MER

  2. 2. Biogenesis, function and regulation of the type III secretion translocon of Yersinia pseudotuberculosis

    Författare :Salah I. Farag; Matthew S Francis; Jörgen Johansson; Åke Forsberg; Luís Jaime Mota; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; type III secretion system; translocation; translocon; regulation; bacteria-eukaryotic cell contact; cytokine profiling;

    Sammanfattning : Many Gram negative bacteria use type III secretion systems to cross-talk with eukaryotic cells. Type III secretion system assembly and function is tightly regulated. LÄS MER

  3. 3. Coordinating type III secretion system biogenesis in Yersinia pseudotuberculosis

    Författare :Jyoti Mohan Gurung; Matthew S Francis; Maria Fällman; Dirk Linke; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; type III secretion system; YscX; YscY; YopN; TyeA; secretion signal; N-terminal region; site-directed mutagenesis; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Sammanfattning : Various Gram-negative bacteria utilize type III secretion system (T3SS) to deliver effectors into eukaryotic host cells and establish mutualistic or pathogenic interactions. An example is the Ysc-Yop T3SS of pathogenic Yersinia species. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
