  1. 1. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

    Author : Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
    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; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    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.

  2. 2. Peptide-Liposome Model Systems for Triggered Release

    Author : Camilla Skyttner; Daniel Aili; Karin Enander; Fredrik Höök; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Liposomes are widely used in drug delivery to improve drug efficacy and to reduce side effects. For liposome-encapsulated drugs to become bioavailable and provide a therapeutic effect they must be released, which typically is a slow process that primarily relies on passive diffusion, liposome rupture or endocytotic uptake.

  3. 3. Antibody- and Peptide-based Immunotherapies : Proof-of-concept and safety considerations

    Author : Erika Fletcher; Sara Mangsbo; Vivianne Malmström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immune complex; conjugat; vaccine; CD40; whole blood; cytokine release syndrome; Immunologi; Immunology;

    Abstract : The aim of cancer immunotherapy is to eradicate tumours by inducing a tumour-specific immune response. This thesis focuses on how antibodies and peptides can improve antigen presentation and the subsequent tumour-specific T cell response. Tumour recognition by the immune system can be promoted through delivery of antigen in the form of a vaccine. READ MORE

  4. 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; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antimicrobial peptide; microgel; degradable; nanogel; drug delivery; PEGylation; secondary structure; model membrane; lipid bilayer; neutron reflectometry; ellipsometry; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

    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

  5. 5. Peptide Conjugates as Useful Molecular Tools

    Author : Adam T. Ślósarczyk; Lars Baltzer; Knud J. Jensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; peptide conjugates; designed peptides; polypeptides; molecular recognition; linker; linking technology; bioconjugation; conjugation; conjugates; Kemi; Chemistry; Chemistry with specialization in Bioorganic Chemistry; Kemi med inriktning mot bioorganisk kemi;

    Abstract : The conjugation of a small organic molecule to synthetic polypeptides from a designed set has been shown to give rise to binders with high affinity and selectivity for the phosphorylated model proteins α-casein and β-casein but not for ovoalbumin. The small organic molecule that was used for this purpose is comprised of two di-(2-picolyl)amine groups assembled on a dimethylphenyl scaffold, and is capable of complexing two Zn2+ ions to form chelates that bind the phosphate ion.
