21. Novel actions of thrombin-derived host defense peptides
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
22. Immunity to Salmonella infection
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
23. Staphylococcus aureus in the infantile bowel flora
Sammanfattning : The increasingly hygienic life-style in Western societies may not only have reduced infections, but may also have altered the composition of the commensal microflora, which may, in turn, have predisposed to e.g. allergy development. Here we investigated the first year s intestinal colonization pattern of a Swedish birth-cohort. LÄS MER
24. Interaction of cyclotides and bacteria : A study of the cyclotide action and the bacterial reaction
Sammanfattning : The growing problem of antibiotic resistance and the lack of promising prospective antibiotics have forced us to search for new classes of antibiotics. Among the candidates to develop into future antibacterials are antimicrobial peptides (AMPs). LÄS MER
25. Chromosomal β-lactamases in enterobacteria and in vivo evolution of β-lactam resistance
Sammanfattning : The ß-lactam antibiotics are the most important antibacterial agents in the treatment of infectious diseases. A severe problem in ß-lactam therapy is the emergence of ß-lactam resistant bacteria. Clinical ß-lactam resistance is most often due to the production of ß-lactamases. ß-lactamase genes reside either on plasmids or on the chromosome. LÄS MER
