  1. 1. Immunity to Salmonella infection

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

    Sammanfattning : 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. LÄS MER

  3. 2. Importance of wild birds in the spread of Salmonella

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

    Sammanfattning : 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. LÄS MER

  4. 3. Presentation of Salmonella antigens by dendritic cells

    Författare :Ulf Yrlid; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serology; Immunology; antigen processing and presentation; Dendritic cells; Salmonella; transplantation; Immunologi; serologi;

    Sammanfattning : This study investigates the interaction between dendritic cells (DC) and the Gram negative intracellular bacterium Salmonella typhimurium. Using in vitro and in vivo approaches, the capacity of DC to directly and indirectly present antigens from Salmonella-infected cells, cytokine production by infected DC, and activation of bacteria-specific T cells was analyzed.

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

    Författare :Anna Rydström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :Salmonella; Monocyte; Neutrophil; Chemokine; Toll-like receptor; Differentiation;

    Sammanfattning : 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. LÄS MER

  7. 5. Formation of Thiolated Nucleosides in tRNA in Salmonella enterica serovar typhimurium

    Författare :Hans Lundgren; Glenn Björk; Charles Lauhon; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; : tRNA; modified nucleosides; thiolation; sulfur metabolism; Salmonella; Molecular biology; Molekylärbiologi;

    Sammanfattning : The presence and synthesis of transfer RNA (tRNA) is highly conserved in all organisms and a lot of genetic material is dedicated to its synthesis. tRNA contains a large number of modified nucleosides and several diverse functions have been found but much about their function is still unknown.
