  1. 16. Activation and Regulation of TRPV1 : Studies in Recombinant Human Neuroblastoma TRPV1-SHSY5Y Cells

    Författare :Johanna EL Andaloussi-Lilja; Anna Forsby; Antonio Ferrer-Montiel; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nociception; neurotrophic factors; eye irritation; stable transfection; Ca2 ; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : TRPV1 is a transmembrane non-selective cation channel with preference for Ca2+. The receptor is primarily localised on dorsal root ganglion neurons and is activated by numerous endogenous and exogenous potentially irritating ligands eliciting pain. LÄS MER

  3. 17. Phosphoinositides control insulin secretion through multiple routes

    Författare :Phuoc My Nguyen; Christina Bark; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Phosphoinositides; PI 4 P; PI 4; 5 P2; Ca2 ; optogenetics; VDCC; Sac2; OSBP; OSW-1; cholesterol; membrane contact sites;

    Sammanfattning : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. LÄS MER

  4. 18. Temporal monitoring of intracellular Ca2+ signaling and origins of Ca2+ oscillations

    Författare :Dominic-Luc Webb; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis examined parameters influencing stimulated cytoplasmic free Ca2+ concentration ([Ca2+]i) oscillations in hepatocytes and pancreatic beta-cells. Hepatic glucose output is regulated in part by hormones such as vasopressin that act through [Ca 2+]i oscillations. LÄS MER

  5. 19. Regulation of exocytosis by Ca2+ and cAMP - A study on pancreatic beta- and alpha-cells

    Författare :Xiaosong Ma; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrinology; secreting systems; type-2 diabetes; SUR1; Ca2 -channel; glucagon; exocytosis; insulin; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Type-2 diabetes is characterized by impaired insulin secretion associated with excess glucagon release. Exocytosis of insulin- or glucagon-containing granules is initiated by Ca2+-influx through voltage-dependent Ca2+-channels and is modulated by the second messengers such as cAMP. LÄS MER

  7. 20. Vacuolar Ca2+-ATPases in Plants. Regulation by calmodulin binding to a N-terminal autoinhibitory domain

    Författare :Susanna Malmström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; N terminus; autoinhibitory domain; vacuole; calmodulin; calcium; plants; Ca2 -ATPase; Växtbiokemi;

    Sammanfattning : The calcium ion (Ca2+) is essential for all plant and animal life. One important function of Ca2+ is as a second messenger in the responses of the cell to environmental and hormonal signals as well as in some intrinsic developmental processes. LÄS MER
