  1. 21. Actions of Antimicrobial Peptides and Bacterial Components in Inflammation

    Författare :Thorgerdur Sigurdardottir; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; LL-37; M1 protein; S. pyogenes; Toll-like receptors; phenylephrine; nitr1c oxide; antimicrobial peptides;

    Sammanfattning : Antimicrobial peptides are evolutionally ancient parts of the innate immune system and their primary role is to protect us from infections. The human cathelicidin-derived antimicrobial peptide, LL-37, not only possesses broad spectrum antimicrobial activities but is also able to bind and neutralize bacterial lipopolysaccharide (LPS), an important trigger of the widespread inflammatory response contributing to septic shock.

  3. 22. Antibacterial materials for wound care applications utilizing antimicrobial peptides

    Författare :Edvin Blomstrand; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; self-assembly; lyotropic liquid crystals; antibacterial surface; Antimicrobial peptides; Pluronic F-127; hydrogels;

    Sammanfattning : The spread of antibiotic resistance among bacteria has shown that the development of alternative treatments of infections is of vital importance. This thesis has looked at one potential candidate, antimicrobial peptides (AMPs), as an alternative or compliment to traditional antibiotics. LÄS MER

  4. 23. Amphiphilic hydrogels functionalized with antimicrobial peptides for wound care

    Författare :Edvin Blomstrand; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infections; Antimicrobial peptides; hydrogels; wound care; lyotropic liquid crystals; antibacterial surfaces; amphiphilic polymers; surface functionalization;

    Sammanfattning : Bacteria have the potential to cause significant harm to us when found in places where we do not want them, such as in wounds. Through the last century, the gold standard of eradicating bacteria in these cases has been with antibiotics. LÄS MER

  5. 24. Relish and the Regulation of Antimicrobial Peptides in Drosophila melanogaster

    Författare :Marika Hedengren Olcott; Barbara Taylor; Jean-Marc Reichhart; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drosophila immunity; NF-kappaB; Relish; antimicrobial peptides; Developmental biology; Utvecklingsbiologi;

    Sammanfattning : The fruit fly Drosophila melanogaster has been a powerful model system in which to study the immune response. When microorganisms breach the mechanical barrier of the insect, phagocytosing cells and a battery of induced antimicrobial molecules rapidly attack them. These antimicrobial peptides can reach micromolar concentrations within a few hours. LÄS MER

  7. 25. Microcapsules for Functionalization of Fibrous Materials: From Formulation Development to Long-term Microbial Infection Control

    Författare :Viktor Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Controlled release; Antimicrobial; Microencapsulation;

    Sammanfattning : In response to growing concerns regarding the impact of antimicrobial agents on the environment and public health, a more sustainable approach to their use in products is needed. The problem originates from rapid and uncontrolled release, leading to difficulties in maintaining long-term efficacy. LÄS MER
