1. 1. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

   Författare :Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

   Sammanfattning : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

3. 2. The Gene Repertoire of G protein-coupled Receptors : New Genes, Phylogeny, and Evolution

   Författare :Þóra Kristín Bjarnadóttir; Helgi B. Schiöth; Robert Fredriksson; Kurt Kristiansen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Bioinformatics; Evolution; GPCR; Phylogeny; Farmakologi; Pharmacological research; Farmakologisk forskning;

   Sammanfattning : The superfamily of G protein-coupled receptors (GPCRs) is one of the largest protein families of mammalian genomes and can be divided into five main families; Glutamate, Rhodopsin, Adhesion, Frizzled, and Secretin. GPCRs participate in most major physiological functions, contributing to the fact that they are important targets in drug discovery. LÄS MER

4. 3. New approaches to data-driven analysis and enhanced sampling simulations of G protein-coupled receptors

   Författare :Oliver Fleetwood; Lucie Delemotte; Erik Lindahl; Ulrich Zachariae; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GPCR; G protein-coupled receptors; Molecular Dynamics; MD; Enhanced Sampling; beta2 adrenergic receptor; beta2; Biological Physics; Biologisk fysik;

   Sammanfattning : Proteins are large biomolecules that carry out specific functions within living organisms. Understanding how proteins function is a massive scientific challenge with a wide area of applications. In particular, by controlling protein function we may develop therapies for many diseases.

   Sammanfattning : G protein-coupled receptors (GPCRs) are one of the largest protein families in mammals. GPCRs are instrumental for hormonal and neurotransmitter signalling and are important in all major physiological systems of the body. LÄS MER

7. 5. Characterization of galanin receptors using chimeric peptides and site-directed mutagenesis

   Författare :Ulla Eriksson Sollenberg; Ülo Langel; Anna-Lena Hulting; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galanin; GPCR; mutagenesis; neuropeptide; Neurochemistry; Neurokemi; Neurochemistry and Neurotoxicology; neurokemi och neurotoxikologi;

   Sammanfattning : Galanin, a 29 (30) amino acid neuropeptide, is found throughout both the central and peripheral nervous systems. It signals via three receptors, GalR1-3, all belonging to the rhodopsin-like G-protein coupled receptors. Galanin and its receptors have been implicated in a vast variety of biological processes.
