1. 36. Molecular simulations of G protein-coupled receptors : A journey into structure-based ligand design and receptor function

   Författare :Pierre Matricon; Jens Carlsson; Bjørn Olav Brandsdal; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G Protein-Coupled Receptor; Molecular Dynamics Simulations; Free Energy Perturbation; Ligand Binding; Fragment-Based Lead Discovery; Molecular Docking Screens; Homology Modeling; GPCR Activation Mechanism; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

   Sammanfattning : The superfamily of G protein-coupled receptors (GPCRs) contains a large number of important drug targets. These cell surface receptors recognize extracellular signaling molecules, which stimulates intracellular pathways that play major roles in human physiology. LÄS MER

3. 37. 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

4. 38. Brain control of energy balance : localization and regulation of proteins involved in the central control of food intake and body weight

   Författare :Maria Collin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :AGRP; arcuate nucleus; brainstem; CART; GABA; Glutamate; GPCR; habenular complex; immunohistochemistry; in situ hybridization; hypothalamus; leptin; leptin receptor; LHA; MCH; NPY; Ob-Rb; POMC; serotonin; STAT3; transporter; ventromedial hypothalamic nucleus; VGLUT1-3.;

   Sammanfattning : Obesity has become a worldwide threat to human well-being and is now so common that it is beginning to replace undernutrition and infectious disease as the most significant contributor to ill health. Obesity increases the risk for aquiring serious diseases such as diabetes type 2, hypertension, coronary heart disease and certain forms of cancer. LÄS MER

5. 39. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

   Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

   Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER

7. 40. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

   Författare :Huamei Fu; Göteborgs universitet; []
   Nyckelord :neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

   Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER
