1. 31. Recruitment, Differentiation, and Function of monocytes during Salmonella infection

   Författare :Anna Rydström; Göteborgs universitet; []
   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

3. 32. Novel actions of thrombin-derived host defense peptides

   Författare :Finja Hansen; Lund Dermatologi och venereologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host defense peptides; Thrombin; Monocytes Macrophages; Gram-negative bacteria; LPS; TLR; Phagocytosis; Inflammation; Endocytosis;

   Sammanfattning : Thrombin-derived C-terminal peptides (TCPs) constitute a novel class of immunomodulatory host defense peptides, generated during infection and inflammation. Previous investigations have shown that TCPs of 2-3 kDa inhibit pro-inflammatory immune responses in vitro and in vivo, but their mode of action remained unclear. LÄS MER

4. 33. Regulation of innate and adaptive immune responses by Gram-positive and Gram-negative bacteria

   Författare :Anna Martner; Göteborgs universitet; []
   Nyckelord :Gram-positive; Gram-negative bacteria; Streptococcus pneumoniae; IL-12; autolysin; pneumolysin; CD4 T cells; monocytes macrophages; dendritic cells;

   Sammanfattning : Bacteria are classified as Gram-positive or Gram-negative, depending on their cell wall structure. The role of the bacterial cell wall in immune regulation is the focus of the current work. Most Gram-positive bacteria stimulate monocytes to produce large amounts of IL-12. LÄS MER

5. 34. Inflammatory mediator response to Gram-positive and Gram-negative bacteria in vitro and in middle ear infections

   Författare :Susann Skovbjerg; Göteborgs universitet; []
   Nyckelord :Gram-positive; Gram-negative; bacteria; cytokines; monocytes macrophages; phagocytosis; Streptococcus pneumoniae; autolysin; acute otitis media; secretory otitis media; children; probiotics;

   Sammanfattning : Based on the structure of the cell wall, bacteria are divided into Gram-positive and Gram-negative. While the cell wall of Gram-positive bacteria is thick, the cell wall of Gram-negatives is very thin and surrounded by an outer membrane with LPS. LÄS MER

7. 35. Innate immunity in Staphylococcus aureus arthritis and sepsis

   Författare :Margareta Verdrengh; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Staphylococcus aureus; mice; sepsis; septic arthritis; neutrophils; monocytes macrophages; GM-CSF; adhesion molecules;

   Sammanfattning : Bacterial arthritis is a severe, rapidly progressing erosive disease with high morbidity and mortality. Staphylococcus aureus is the most common causative bacterium. Granulocytes together with cells from the monocyte/macrophage lineage, are the earliest leukocytes entering the synovial tissue in response to invading staphylococci. LÄS MER
