  2. 1. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

    Author : Lukas Boge; Martin Andersson; Lovisa Ringstad; RISE; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Liquid crystals; liquid crystalline nanoparticles; cubosome; hexosome; phase behavior; antimicrobial peptide; AMP; glycerol monooleate; proteolysis; antimicrobial effect; antimicrobial resistance; bacterial membrane; membrane interaction; infection; topical delivery; pulmonary delivery;

    Abstract : The development of antimicrobial resistance is a great challenge within health sectors worldwide. Thus, demand for new, efficient treatments is urgent in order to treat various bacterial infections. Antimicrobial peptides (AMPs) are a group of antibiotics that have gained more and more attraction in the past decade. READ MORE

  4. 2. Development of antimicrobial peptides : Methodological aspects, design, synthesis and evaluation of a new class of antimicrobial peptides

    Author : Marie Danielsson; Anders Undén; Maria Kempe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : A new protective group for the indole nitrogen of the amino acid tryptophan, the Boc-sarcosinoyl-sarcosinolyl (Boc-Sar-Sar) is described. This protective group shows good stability to the reaction conditions used in solid phase peptide synthesis and can be incorporated into the peptide as Fmoc-Trp(Boc-Sar-Sar)-OH. READ MORE

  5. 3. Antimicrobial potential of Geobacillus sp. ZGt-1 isolated from Zara hot spring in Jordan : Piecing the puzzle of the antagonistic activity of a novel bacterial strain

    Author : Rawana Alkhalili; Bioteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermophiles; Geobacillus; antimicrobial potential; antimicrobial peptides; bacteriocins; lanthipeptides; toxin-antitoxin; genome sequence;

    Abstract : The problem of antibiotic resistance is rising continuously, creating a warning signal that calls for finding alternatives. Not only that, but there is also a rising demand for natural food preservatives. The pharmaceutical and food industry sectors are working on fulfilling these needs. This thesis is exploring possible solutions to these issues. READ MORE

  6. 4. Polymeric Nanoparticles as Carriers for Antimicrobial Peptides : Factors Affecting Peptide and Membrane Interactions

    Author : Randi Nordström; Martin Malmsten; Per Hansson; Helena Bysell; Erica Wanless; Uppsala universitet; []

    Abstract : As resistance towards conventional antibiotics is becoming more pronounced, cationic antimicrobial peptides (AMPs) have received considerable attention as possible therapeutic alternatives. Thousands of potent AMPs occur in humans, animals, plants and fungi as a natural part of the immune system. READ MORE

  7. 5. Pathogenic Neisseria : Single cell motility, multicellular dynamics and antimicrobial susceptibility

    Author : Olaspers Sara Eriksson; Ann-Beth Jonsson; Matthew Francis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neisseria; Type IV pili; Twitching motility; PilT; Microcolony dynamics; PilU; NafA; Antimicrobial peptide; Cell-penetrating peptide; molekylär biovetenskap; Molecular Bioscience;

    Abstract : Neisseria meningitidis and Neisseria gonorrhoeae can colonize humans without causing any symptoms. However, gonorrhea and invasive meningococcal disease are serious health concerns. An essential virulence factor for neisserial adhesion to host cells, twitching motility and microcolony formation/aggregation is the retractile type IV pili (Tfp). READ MORE
