  1. 1. Cellular Dyes and Bioactive Peptides - Cell Membrane Interactions and Cellular Uptake

    Författare :Maria Matson Dzebo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane Interactions; Spectroscopy; Cell-Penetrating Peptides; Bioactive Peptides; Cell Membrane; Confocal Laser Scanning Microscopy; Cellular Uptake; AF-16; Voltage-Sensitive Dyes; Cell Dyes; Antisecretory Factor; Ruthenium Complexes; Isothermal Titration Calorimetry; Flow-Cytometry;

    Sammanfattning : Knowledge about mechanisms behind interactions of molecules with biomembranes and cellular uptake is very important for understanding biological processes and for drug design. The work described in this thesis has focused on interactions of cellular dyes and bioactive peptides with cells and the cell membrane. LÄS MER

  3. 2. Cell-penetrating peptides and bioactive cargoes : Strategies and mechanisms

    Författare :Kalle Kilk; Ülo Langel; Michael J. Gait; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; delivery; Peptide nucleic acid; Biochemistry; Biokemi;

    Sammanfattning : The cell membrane is an impermeable barrier for most macromolecules. Recently discovered cell-penetrating peptides (CPPs) have gained lot of attention because they can cross the membrane, and even more, carry cargoes with them. How CPPs enter cells is still not clear, while the delivery of different cargoes has been convincingly shown. LÄS MER

  4. 3. Bioactive peptides and proteins in disease

    Författare :Essam Refai; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Regulatory peptides and marker proteins are important to study in order to understand disease mechanisms. This applies of course also to our common diseases where all relationships are not yet known. Cancer and diabetes are two such complex diseases that affect hundreds of millions of people worldwide.

  5. 4. Isolation, structure and processing of bioactive peptides

    Författare :Valentina Bonetto; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Amino acid sequences deduced from DNA sequences do not prove in which forms proteins, peptides and their processed products are present in the tissues. The products of a single gene may give rise to variants of peptides because of post-transcriptional or post-translational processing. LÄS MER

  7. 5. Purification, structure and function of bioactive peptides

    Författare :Elo Eriste; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Peptides are vitally important molecules and many evoke cellular responses. The completion of several genome sequencing projects has revealed a number of new genes. LÄS MER
