16. Receptor-ligand interactions of the human 5-HT1B receptor : A site-directed mutagenesis study
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
17. Aspects of proteinase-activated receptor-2: A sensor of enzymatic activity at the cell surface
Sammanfattning : Information about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). LÄS MER
18. G Protein-Coupled Receptors; Discovery of New Human Members and Analyses of the Entire Repertoires in Human, Mouse and Rat
Sammanfattning : G protein-coupled receptors (GPCRs) are signal mediators that have a prominent role in the regulation of physiological processes and they make up the targets for 30-45% of all drugs. Papers I and II describe the discovery of new human GPCRs belonging to the Rhodopsin family, a family which contains many common drug targets. LÄS MER
19. Studies of a Proteinase-activated Cell Surface Receptor
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
20. Immunopathogenesis of Gai2-deficient mice. A model of inflammatory bowel disease
Sammanfattning : The intestinal mucosa is the largest lymphoid organ in the body, and it simultaneously has to protect us from any pathogen that might enter the gastrointestinal tract as well as maintaining tolerance to most antigens, mainly in the form of dietary constituents and microbial products. A dysfunctional control of local intestinal immune responses may lead to development of Inflammatory Bowel Disease (IBD) - the common name for ulcerative colitis (UC) and Crohn´s disease (CD). LÄS MER
