  1. 6. The multifunctional GAP protein YopE of Yersinia is involved in effector translocation control and virulence

    University dissertation from Umeå : Umeå universitet

    Author : Elin Isaksson; Hans Wolf-Watz; Joseph Barbieri; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Yersinia; T3SS; YopE; GAP activity; translocation control; virulence; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The Gram-negative bacterium Yersiniapseudotuberculosis employs a type 3 secretion system (T3SS) to establish infections. The T3SS translocates a diverse set of effector proteins directly into the host cells. READ MORE

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

    University dissertation from Umeå : Umeå universitet

    Author : Ingrid Bölin; []
    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

  3. 8. Meticulous control of the T3SS of Yersinia is essential for full virulence

    University dissertation from Umeå : Institutionen för molekylärbiologi, Teknisk-naturvetenskaplig fakultet, Umeå universitet

    Author : Ann-Catrin Björnfot; Hans Wolf-Watz; Kelly T. Hughes; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Yersinia; type III secretion; YscU; substrate specificity switch; heat shock proteins; VagH; methyltransferase; virulence; NATURAL SCIENCES Chemistry Biochemistry Molecular biology; NATURVETENSKAP Kemi Biokemi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The type III secretion system (T3SS) of pathogenic Yersinia pseudotuberculosis is involved in virulence. The syringe-like secretion system spans both bacterial membranes and is responsible for the ability of Yersinia to transfer toxic proteins (Yop proteins) into the eukaryotic target cell. READ MORE

  4. 9. Multiple functions of YopN in the Yersinia pseudotuberculosis type III secretion system from regulation to in vivo infection

    University dissertation from Umeå : Umeå University

    Author : Sarp Bamyaci; Åke Forsberg; Edouard Galyov; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Type III secretion system; Yersinia; YopN; virulence; phagocytosis; mouse infection; secretion kinetics;

    Abstract : The type 3 secretion systems (T3SSs) are virulence mechanisms used by various Gram-negative bacteria to overcome the host immunity. They are often target-cell contact induced and activated. Activation results in targeting of virulence effector substrates into host cells. READ MORE

  5. 10. Antiphagocytosis by Yersinia pseudotuberculosis role of the YopH target proteins

    University dissertation from Umeå : Molekylärbiologi

    Author : Ming Yuan; Maria Fallman; Tommy Nilsson; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular biology; Cas; Fyb; mAbp1; SKAP-HOM; Yersinia pseudotuberculosis; YopH; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The enteropathogenic bacterium Yersinia pseudotuberculosis binds to β1 integrins on a host cell via its surface protein invasin. This event stimulates signal transduction to the actin cytoskeleton of the eukaryotic cell, which allows the cell to engulf the bacterium that is attached to its surface. However, the pathogen Y.
