1. 6. Studies of a Proteinase-activated Cell Surface Receptor

   Författare :Sverker Nystedt; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; receptor; proteinase; PAR-2; molecular cloning; in situ hybridisation; Expression; G-protein; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : The G protein-coupled receptors form one of the largest families of proteins involved in signalling between cells. It contains receptors for molecules as diverse as biogenic amines, glycoproteins and enzymes. The manuscripts included in this thesis together describe the initial characterisation of a previously unknown receptor of this class. LÄS MER

3. 7. Structure-based Virtual Screening for Ligands of G Protein-coupled Receptors : Design of Allosteric and Dual-Target Modulators

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; G protein-coupled receptors; Polypharmacology; Molecular Docking; Structure-based Drug Design; Parkinson’s Disease; Virtual Screening; Allosteric Modulators; Bioinformatics; Bioinformatik;

   Sammanfattning : G protein-coupled receptors (GPCRs) are integral membrane proteins responsible for signal transduction of extracellular stimuli into the cell. Because of their widespread distribution throughout the human body and important roles in physiological processes, GPCRs are prominent drug targets and approximately 34% of all approved drugs interact with members of this superfamily.

   Sammanfattning : The 5-hydroxytryptamine (5-HT, serotonin)1B receptor is one of thirteen G protein-coupled 5-HT receptors. 5-HT is known to influence temperature regulation, pain, cognition and sexual and feeding behaviours. LÄS MER

5. 9. Molecular Pharmacology and Structure Function Modelling of the Leukotriene B4 Receptor BLT1

   Sammanfattning : Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LÄS MER

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

   Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []

   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
