  1. 1. Discovery of Novel Receptors for Lipid Mediators - a study leading to the identification of receptors involved in metabolism and the immune system

    Författare :Niclas Nilsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk biologi; Clinical biology; Thiazolidinedione; SCFA; FFA; FFA2R; FFA1R; GPR43; GPR41; GPR40; BLT2; GPCR; Orphan; Receptor;

    Sammanfattning : Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. LÄS MER

  3. 2. The Free Fatty Acid Receptor GPR40 - expression and role in islet hormone secretion

    Författare :Erik Flodgren; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; GPCR; Glucagon; GPR40; Insulin; Free fatty acid; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Type 2 diabetes (T2D) is a serious condition of growing proportions. Developing via an increasing imbalance between insulin sensitivity in the peripheral tissues and insulin release from pancreatic beta-cells, it ultimately renders the individual incapable of regulating the blood glucose concentration, e.g. after a meal.

  4. 3. Effects of Free Fatty Acids on Insulin and Glucagon Secretion : – with special emphasis on the role of Free fatty acid receptor 1

    Författare :Hjalti Kristinsson; Peter Professor; Birgitte Holst; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FFAR1; GPR40; palmitate; lipotoxicity; islets of Langerhans; type 2 diabetes; obesity; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Prevalence of type 2 diabetes mellitus (T2DM) is still rising and even so in the juvenile population. Obesity is highly associated with increased risk for developing T2DM. LÄS MER

  5. 4. Mechanisms underlying lipotoxicity and glucotoxicity in pancreatic islets

    Författare :Sandra Meidute; Islet cell physiology; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hormone secretion; cell stress; Pancreatic beta-cell; cellular signalling; GPR40; diabetes;

    Sammanfattning : Although it has been known for many years that long-term exposure of pancreatic islets to a high level of free fatty acids (FFA) or glucose negatively modulates islet hormone release, the identities of signals mediating these effects are not yet fully clarified. The overall objective of this study was to investigate signal transduction pathways involved in FFA- and glucose-exerted effects on beta-cell function during both short-term as well as long-term exposure.

  7. 5. Development of sensitive cellular assay systems and their application to the identification of "orphan" seven-transmembrane receptors

    Författare :Knut Kotarsky; Slemhinnans immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biokemi; Metabolism; Biochemistry; metabolism; leukotrieneB4; thiazolidinedione; 9-HODE; fatty acid; luciferase; GFP; reporter gene; preclinical assay; receptor; GPCR;

    Sammanfattning : Seven-transmembrane, G-protein coupled receptors play a central role in physiology since they facilitate cell communication in multicellular organisms by recognition of a broad range of ligands. They also represent important drug targets. LÄS MER
