  1. 6. Endogenous Opioids and Voluntary Ethanol Drinking : Consequences of Postnatal Environmental Influences in Rats

    Författare :Lisa Gustafsson; Ingrid Nylander; Erika Roman; Ryszard Przewlocki; Uppsala universitet; []
    Nyckelord :Pharmaceutical pharmacology; Maternal separation; Maternal deprivation; Handling; Isolation; Alcohol; Two-bottle model; Four-bottle model; MEAP; Dynorphin B; Nociceptin orphanin FQ; Radioimmunoassay; Farmaceutisk farmakologi;

    Sammanfattning : Genetic and environmental factors interact to determine the individual vulnerability to develop ethanol dependence. The neurobiological mechanisms underlying these processes are not fully understood. Endogenous opioid peptides have been suggested to contribute. LÄS MER

  3. 7. Biophysical studies of membrane associated peptides

    Författare :Jesper Lind; Astrid Gräslund; Lena Mäler; Christian Griesinger; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; spectroscopy; membrane interaction; bicelles; Chemistry; Kemi; Biophysics; biofysik;

    Sammanfattning : A large part of the processes in living organisms involves proteins acting in a biological membrane. Biophysical studies on isolated model systems can give important understandings of the complicated biological mechanisms in the membrane. In this thesis peptide membrane interaction mechanisms are studied in several different systems. LÄS MER

  4. 8. Design and Synthesis of Novel AT2 Receptor Ligands : From Peptides to Drug-Like Molecules

    Författare :Jennie Georgsson; Anders Hallberg; Kevin Burgess; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; angiotensin II; AT1; AT2; AT2 receptor agonist; peptidomimetics; γ-turn mimetics; carbonylation; microwave; molybdenum hexacarbonyl; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Sammanfattning : Many peptide receptors are of pharmaceutical interest and there is thus a need for new ligands for such receptors. Unfortunately, peptides are not suitable as orally administrated drugs since they are associated with poor absorption, rapid metabolism and low sub-receptor selectivity. LÄS MER

  5. 9. Targeting bacterial infections by using immunomodulatory host defence peptides and proteins

    Författare :Martina Kalle; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host dfence peptides; Sepsis; Immunomodulation; Heparin cofactor II;

    Sammanfattning : Bacterial infections and sepsis are amongst the leading causes of death worldwide. Sepsis is caused by an uncontrolled systemic host response towards an invading pathogen. Due to the engagement of various systems including cellmediated responses, the coagulation and complement cascades, treatment of sepsis remains challenging. LÄS MER

  7. 10. Diving into short linear motifs : Large-scale identification of endogenous and host-pathogen protein-protein interactions and further characterized by deep mutational scanning

    Författare :Caroline Benz; Ylva Ivarsson; Birthe B. Kragelund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein-protein interactions; short linear motif; endogenous interactions; host-pathogen; viral hijacking; deep mutational scanning; Biokemi; Biochemistry;

    Sammanfattning : Short linear motifs (SLiMs) are protein-protein interaction sites that play an essential role in distinct cellular processes. Those interactions are challenging to capture by common high-throughput methods. LÄS MER
