  1. 21. Functional Studies of the Neuropeptide Y System : Receptor-Ligand Interaction and Regulation of Food Intake

    Författare :Helena Åkerberg; Dan Larhammar; Rickard Malmström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropeptide Y; G-protein coupled receptor GPCR ; site-directed mutagenesis; pancreatic polypeptide; food intake; dog; Pharmacology; Farmakologi;

    Sammanfattning : The members of the mammalian neuropeptide Y family, i.e. the peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), are all involved in regulation of food intake. In human and most other mammals they act via receptors Y1, Y2, Y4 and Y5. LÄS MER

  3. 22. Molecular evolution of the neuropeptide Y receptor family : Insights from mammals and fish

    Författare :Amanda Wraith; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : Most genes in the genomes of vertebrates form families with multiple members that are more or less closely related. This thesis concerns investigations of the neuropeptide Y (NPY) family of peptides and the family of receptors to which these peptides bind, the NPY receptors. LÄS MER

  4. 23. Identification and characterisation of five innate immune genes in the cabbage looper Trichoplusia ni

    Författare :Annika Lundström; Lage Cerenius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mikrobiologi; Microbiology;

    Sammanfattning : When insects are infected with bacteria, they respond by producing a range of different antibacterial peptides and by activating protease cascades leading to coagulation and melanisation. Cellular defence mechanisms are also involved in killing of microorganisms through phagocytosis and encapsulation. LÄS MER

  5. 24. Distribution and connectivity of messenger molecules in the control of energy metabolism : focus on neuropeptides and calcium binding proteins

    Författare :Kylie S Foo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Feeding is an essential and complex behavior which aims to provide the energy required for maintaining physiological homeostasis. The drive to feed is a powerful stimulus arising from metabolic demands, and reinforced by evolutionary pressure. LÄS MER

  7. 25. Oral tolerance mechanisms and the role of the microbiota

    Författare :Sofia M Östman; Göteborgs universitet; []
    Nyckelord :;

    Sammanfattning : The hygiene hypothesis state that microbial stimulation is necessary to fully activate and mature the immune system and to sustain tolerance mechanisms. Oral tolerance maintains immune homeostasis in the gut and prevents adverse reactions towards the comensal flora and Ags from the food and thus protects from development of allergies and inflammatory bowel diseases (IBD).
