  1. 1. Antimicrobial Peptide Interactions with Phospholipid Membranes Effects of Peptide and Lipid Composition on Membrane Adsorption and Disruption

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Adam A Strömstedt; Uppsala universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial; peptide; adsorption; liposome; membrane; melittin; cholesterol; tryptophan; phospholipid; bilayer; PHARMACY; FARMACI; farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : The interactions between antimicrobial peptides and phospholipid membranes were investigated, in terms of lipid headgroup variations and the role of cholesterol, as well as peptide composition and structure. Also strategies for increasing proteolytic stability were evaluated. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Shalini Singh; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : 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. READ MORE

  3. 3. Microgel Interactions with Peptides and Proteins Consequence of Peptide and Microgel Properties

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ronja Widenbring; Uppsala universitet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Abstract : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

  4. 4. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins

    University dissertation from Organic Chemistry, Lund University

    Author : Katarina Flemmer Karlsson; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CD spectroscopy; NMR spectroscopy; peptide structure; ELISA; solid-phase peptide synthesis; peptide; P pili; chaperone; Organic chemistry; Organisk kemi;

    Abstract : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. READ MORE

  5. 5. Identification and Characterization of Peptides and Proteins using Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Palmblad; Uppsala universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Peptide; protein; peptide mass fingerprinting; identification; sequencing; protein structure; non-covalent interaction; modification; electrospray ionization; liquid chromatography; capillary electrophoresis; electron capture dissociation; Fourier transform ion cyclotron resonance mass spectrometry; cerebrospinal fluid; amyloid β-peptide; Alzheimer’s disease.; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Mass spectrometry has in recent years been established as the standard method for protein identification and characterization in proteomics with excellent intrinsic sensitivity and specificity. Fourier transform ion cyclotron resonance is the mass spectrometric technique that provides the highest resolving power and mass accuracy, increasing the amount of information that can be obtained from complex samples.
