  1. 6. Role of the Yersinia protein YopK in microbe-host interactions

    University dissertation from Umeå : Umeå universitet

    Author : Sara Thorslund; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia; YopK; T3SS; antiphagocytosis; neutrophil; translocation; virulence; molekylärbiologi; Molecular Biology;

    Abstract : There are three human pathogenic species of the genus Yersiniae: Yersinia pestis, Yersinia enterocolitica, and Yersinia pseudotuberculosis. To cause disease, these strains inhibit several key innate defense mechanisms, including phagocytosis, the critical process for bacterial clearance. READ MORE

  2. 7. Twin-arginine translocation in Yersinia the substrates and their role in virulence

    University dissertation from Umeå : Umeå University

    Author : Ummehan Avican; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Yersinia pseudotuberculosis; Tat; virulence; Tat substrates; SufI; stress response; metabolism; infection; transcriptome analysis; Infectious Diseases; infektionssjukdomar; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

    Abstract : Pathogenic Yersinia cause a manifold of diseases in humans ranging from mild gastroenteritis (Y. pseudotuberculosis and Y. enterocolitica) to pneumonic and bubonic plague (Y. READ MORE

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

    University dissertation from Umeå : Umeå universitet

    Author : Elin Isaksson; Umeå universitet.; [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 Yersinia pseudotuberculosis 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

  4. 9. 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; Umeå universitet.; [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

  5. 10. 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; Umeå universitet.; Umeå universitet.; Umeå universitet.; [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
