1. 21. Dendritic cell maturation and death during Salmonella infection. Role of pro-inflammatory cytokines and MyD88

   Författare :Malin Sundquist; Göteborgs universitet; []
   Nyckelord :Dendritic cells; Costimulatory molecules; Bacterial infection; Pro-inflammatory cytokines; Toll-like receptors; Ag presentation; Cell death;

   Sammanfattning : The costimulatory molecules CD80 and CD86 are required for the ability of dendritic cells (DC) to induce both tolerance and immunity. This thesis investigates the control of CD80/CD86 upregulation in vivo on DC during Salmonella infection. LÄS MER

3. 22. The osteogenic potential of human mesenchymal stem cells: Novel markers and key factors for differentiation

   Författare :Cecilia Granéli; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mesenchymal stem cells; Mesenchymal stromal cells; Osteogenic differentiation; Adipogenic differentiation; Bone regeneration; Inflammation; Monocytes; Infection; Bacterial membrane vesicles; Compromised bone healing; Cell surface proteins; CD-markers; Osseointegration; Regenerative medicine;

   Sammanfattning : Mesenchymal stem cells are multipotent stem cells with ability to differentiate into cells of the connective tissue lineage, such as adipocytes, osteoblasts and chondrocytes, both in vitro and in vivo. The main objective of the present thesis was to study different aspects of the osteogenic potential of MSCs. LÄS MER

4. 23. Immunity to Salmonella infection

   Författare :Cecilia Johansson; Immunologi; []
   Nyckelord :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

5. 24. Macrophage programming and host responses to bacterial infection

   Författare :Xiao Wang; Hong Sjölinder; Martin Rottenberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Macrophages; meningococci; mycobacteria; NhhA; CD46; cytokines; molekylärgenetik; Molecular Genetics;

   Sammanfattning : Macrophages are dynamic, plastic, and heterogeneous immune cells that play an important role in host immune defense against bacterial infection. Various bacterial pathogens, such as Neisseria meningitidis and Mycobacterium tuberculosis, can modulate host immune responses by interfering with macrophage differentiation and polarization.

7. 25. Host-bacterium relationship in staphylococcal skin infection

   Författare :Lena Mölne; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Staphylococcus aureus; skin; mice; superantigen; TSST-1; neutrophils; gamma delta T cells; bacterial DNA; CpG ODN;

   Sammanfattning : Skin infections caused by Staphylococcus aureus are commonly occuring, both in the community and in hospitals. Despite the high prevalence of this condition, little is known about the host immune responsiveness and bacterial virulence factors during S. aureus skin infection. LÄS MER
