1. 11. Calcium and Phospholipases in Orexin Receptor Signaling

   Författare :Lisa Johansson; Jyrki Kukkonen; Karl Åkerman; Christopher S. Leonard; Uppsala universitet; []
   Nyckelord :Physiology; orexin; receptor; calcium; phospholipase; cell signaling; GPCR; Fysiologi;

   Sammanfattning : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).

3. 12. Orexin Receptors in Recombinant CHO Cells : Signaling to Short- and Long-Term Cell Responses

   Författare :Sylwia Ammoun; Jyrki Kukkonen; Karl Åkerman; Gunnar Flemström; Christer Larsson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; orexins; cell signaling; Neurovetenskap; Neurology; Neurologi;

   Sammanfattning : Recently discovered neuropeptides orexins (orexin-A and -B) act as endogenous ligands for G-protein-coupled receptors called OX1 and OX2 receptors. Our previous studies have established model systems for investigation of the pharmacology and signaling of these receptors in recombinant CHO cells. LÄS MER

4. 13. Regulation of Phospholipase C and Plasma Membrane Phosphatidylinositol 4,5-bisphosphate in Insulin-Secreting Cells

   Författare :Sophia Thore; Anders Tengholm; Erik Gylfe; Peter Jones; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; PLC; PIP2; insulin-secreting cell; Ca2 ; evanescent wave microscopy; phosphoinositide kinase; ATP ADP ratio; Cellbiologi; Cell biology; Cellbiologi;

   Sammanfattning : The membrane phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) is an important signaling molecule as substrate for the phospholipase C (PLC)-catalyzed formation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol, and by directly regulating e.g. ion-channels, the cytoskeleton and vesicle trafficking in various types of cells.

5. 14. Membrane lipids and their transfer proteins in β-cells

   Författare :Beichen Xie; Olof Idevall-Hagren; Anders Tengholm; Jen Liou; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ca2 ; PKC; E-Syt1; TMEM24; ER-PM contact; PI 4; 5 P2; phosphoinositides; β-cell; insulin; optogenetics; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

   Sammanfattning : Insulin secretion from β-cells is essential for glucose homeostasis and is often dysregulated in diabetes. Intracellular Ca2+ and membrane lipids cooperate to control insulin secretion with high spatial and temporal precision. LÄS MER

7. 15. Shb and Its Homologues: Signaling in T Lymphocytes and Fibroblasts

   Författare :Cecilia Lindholm; Hamid Band; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Shb; T cell receptor; IL-2 receptor; PDGF receptor; cell signaling; adapter proteins; LAT; Vav; PLC-g1; SLP-76; JAK1; JAK3; Jurkat cells; T cells; NK cells; Apoptosis.; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

   Sammanfattning : Stimulation of the T cell receptor (TCR) induces tyrosine phosphorylation of numerous intracellular proteins, leading to activation of the interleukin-2 (IL-2) gene in T lymphocytes. Shb is a ubiquitously expressed adapter protein, with the ability to associate with the T cell receptor and several signaling proteins in T cells, including: the TCR ζ-chain, LAT, PLC-γ1, Vav, SLP-76 and Gads.
