  2. 1. Immunity to Salmonella infection

    Author : Cecilia Johansson; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; cytokines; antigen presentation; liver; dendritic cells; Salmonella; gram negative bacteria;

    Abstract : The immune system has several strategies to combat infections. The present study investigates various aspects of the interaction between Gram negative bacteria, particularly Salmonella, and antigen presenting cells (APC). Salmonella is an intracellular bacterium infecting mice and man. READ MORE

  4. 2. Recruitment, Differentiation, and Function of monocytes during Salmonella infection

    Author : Anna Rydström; Göteborgs universitet; []
    Keywords : Salmonella; Monocyte; Neutrophil; Chemokine; Toll-like receptor; Differentiation;

    Abstract : Monocytes are a heterogeneous population in the blood with an enormous plasticity whose fate and functions are dictated by the microenvironment. They are phenotypically and functionally related to neutrophils and dendritic cells (DCs) and share an overlapping expression pattern of surface molecules with these cells. READ MORE

  5. 3. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Author : Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    Abstract : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.

  6. 4. Importance of wild birds in the spread of Salmonella

    Author : Helena Palmgren; Björn Olsen; Bo Svenungsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; wild birds; Black-headed gull; Peregrine falcon; Antarctica; penguins; seals; PFGE; IS200; salmonella carriage;

    Abstract : Salmonella is one of the most important enteropathogenic bacteria. It is responsible for about 5000 reported cases of human gastroenteritis each year in Sweden. Salmonellosis is a zoonotic disease, and the bacterium has the ability to infect a variety of both domestic and wild animal species. READ MORE

  7. 5. Immuno-modulatory functions of CD1d-restricted natural killer T cells

    Author : Emma Berntman; Immunologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; Medicin människa och djur ; Medicine human and vertebrates ; microarray; gene expression signature; infection; Salmonella; CD1d; NKT cells;

    Abstract : This thesis focuses on a small population of non-conventional T lymphocytes, called natural killer T (NKT) cells. NKT cells have many unique features; such as recognition of glycolipids presented by CD1d, expression of NK receptors and rapid production of large amounts of cytokines, such as IL-4 and IFN-gamma,?upon activation.
