  1. 1. Amphiphilic Peptide Interactions with Complex Biological Membranes : Effect of peptide properties on antimicrobial and anti-inflammatory effects

    Författare :Shalini Singh; Martin Malmsten; Per Hansson; Debora Berti; Uppsala universitet; []
    Nyckelord :LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Sammanfattning : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. LÄS MER

  3. 2. Bacterial Resistance to Antimicrobial Peptides : Rates, Mechanisms and Fitness Effects

    Författare :Maria Pränting; Dan Andersson; Ian Chopra; Uppsala universitet; []
    Nyckelord :antimicrobial peptides; antibiotic resistance; fitness cost; bacterial evolution; small colony variants; cyclotides; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Mikrobiologi; Microbiology;

    Sammanfattning : The rapid emergence of bacterial resistance to antibiotics has necessitated the development of alternative treatment strategies. Antimicrobial peptides (AMPs) are important immune system components that kill microbes rapidly and have broad activity-spectra, making them promising leads for new pharmaceuticals. LÄS MER

  4. 3. Antimicrobial peptides in the treatment of infectious and inflammatory conditions : Preclinical studies of mechanism of action, efficacy, and safety

    Författare :Camilla Björn; RISE; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; AMPs; innate immunity; infection; inflammation; mechanism of action; efficacy; safety; antimicrobial resistance; antibiotic resistance; Antimicrobial peptides; AMPs; innate immunity; infection; inflammation; mechanism of action; efficacy; safety; antimicrobial resistance; antibiotic resistance;

    Sammanfattning : The rapid emergence of antibiotic-resistant microbes worldwide and the urgent need of new antimicrobial agents have stimulated interest in antimicrobial peptides (AMPs) as new therapeutics for treatment of infectious diseases. AMPs are present in all living species and constitute an important part of the innate immune system in multicellular organisms, including humans. LÄS MER

  5. 4. Lipid-based liquid crystals as drug delivery vehicles for antimicrobial peptides

    Författare :Lukas Boge; Martin Andersson; Lovisa Ringstad; RISE; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Antimicrobial peptides and virulence factors in meningococcal colonisation and disease

    Författare :Miriam Geörg; Ann-Beth Jonsson; Ole E. Sørensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; antimicrobial peptide; LL-37; cell-penetrating peptide; resistance; polynucleotide phosphorylase; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The Gram-negative bacterium Neisseria meningitidis is a transient commensal of the human nasopharynx, but occasionally causes life-threatening disease. During colonisation of its niche, N. meningitidis has to overcome innate immune defences, including the expression of antimicrobial peptides (AMPs). LÄS MER
