  2. 6. Multiple functions of YopN in the Yersinia pseudotuberculosis type III secretion system : from regulation to in vivo infection

    Author : Sarp Bamyaci; Åke Forsberg; Edouard Galyov; Umeå universitet; []
    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

  4. 7. Perturbation of the epithelial barrier by enteric pathogens

    Author : Farideh Tafazoli; Magnusson Karl-Eric; Hakon Leffler; Linköpings universitet; []
    Keywords : enteric pathogens: signal transduction; barrier function; MEDICINE; MEDICIN;

    Abstract : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. READ MORE

  5. 8. Role of the Yersinia protein YopK in microbe-host interactions

    Author : Sara Thorslund; Maria Fällman; James Bliska; Umeå universitet; []
    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

  6. 9. 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
