  1. 1. 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. 2. Computational prediction of receptor-ligand binding affinity in drug discovery

    Författare :John Marelius; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; computer-aided ligand design; molecular dynamics simulation; linear interaction energy; free energy perturbation; scoring function; dihydrofolate reductase; thrombin; serine proteases; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; molekylär bioteknik avd f jonfysik ;

    Sammanfattning : The evaluation of inhibition constants or, more generally, receptor-ligand binding affinities is a crucial part of the drug discovery process. Chemical synthesis and affinity screening is only affordable for a limited number of compounds. This makes computational methods to predict binding affinities of candidate ligands highly desirable.

  4. 3. Deciphering Binding Patterns of Therapeutic Antibodies with Immune Cells : From Method Development to Application

    Författare :Sina Bondza; Jos Buijs; Marika Nestor; Mark Cragg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; affinity; binding kinetics; CD20; cell-based assay; immunology; receptor-ligand interaction; therapeutic antibody; Immunologi; Immunology; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Reversible binding, for example between signaling molecules and receptors on the cell surface, is one of the main means to communicate information in cellular systems. Knowledge about how molecules interact is crucial for both understanding biological function and for therapeutic intervention. LÄS MER

  5. 4. The G-protein coupled receptor CMKLR1/ChemR23: Studies on gene regulation, receptor ligand activation, and HIV/SIV co-receptor function

    Författare :Ulrika Mårtensson; Drug Target Discovery; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; HIV SIV; TIG2 chemerin; transcriptional regulation; ligand activation; Co-receptor; GPCR; ChemR23 CMKLR1;

    Sammanfattning : In all higher organisms, there is a need for intercellular communication. G-protein coupled receptors (GPCRs), located on the cell surface, play an important role in this communication. Cells synthesize and release signalling molecules (ligands), which produce a specific response only in those cells that have a receptor for that ligand. LÄS MER

  7. 5. Characterization of Substance P (SP) Aminoterminal SP (1-7) Binding in Brain Regions and Spinal Cord of the Male Rat : Studies on the Interaction with Opioid Related Pathways

    Författare :Milad Botros; Fred Nyberg; Tsukasa Sakurada; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological research on drug dependence; Biologisk beroendeforskning;

    Sammanfattning : Binding sites for substance P(1-7), SP(1-7) have been identified and characterized for the first time in crude membrane fraction from rat CNS using tritiated ([3H]) SP(1-7) as tracer. These putative receptors were investigated in relation to their affinity for tachykinins, opioid peptides and sigma receptor ligands. LÄS MER
