  1. 6. Chemoattractant receptor signaling and neutrophil acctivation. Involvement of the cytoskeleton

    Författare :Huamei Fu; Göteborgs universitet; []
    Nyckelord :neutrophils; G-protein coupled receptors; signaling; cytoskeleton;

    Sammanfattning : Neutrophil granulocytes play a vital role in the host surveillance system and form the first line of defense against microbial infections. The migration of neutrophils to an infected/inflamed tissue is guided by chemoattractants released either from intruding microbes or from activated/damaged host cells. LÄS MER

  3. 7. Studies on molecular mechanisms in calcium signaling and cellular energy consumption

    Författare :Kalaiselvan Krishnan; Hjalmar Brismar; Anders Tengholm; KTH; []
    Nyckelord :ca2 signaling; ATP; PercevalHR; NKA; diabetes; Angiotensin; Biological Physics; Biologisk fysik;

    Sammanfattning : Ion signaling plays fundamental role in cell survival. Na+ and Ca2+ are critical players in ion signaling. Cells spend the major amount of energy to maintain and regulate Na+ and Ca2+ gradients across the cell membrane. Any disruption in cellular energy consumption by plasma membrane ATPases affects ion signaling and vice versa. LÄS MER

  4. 8. Analysis of PDGF receptor internalization and signaling using proximity ligation assays

    Författare :Marie Rubin Sander; Ola Söderberg; Cristina Al-Khalili Szigyarto; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGFRβ; dynamin; proteolytic cleavage; signaling; internalization; protein-protein interaction; short linear motif; viral hijack; in situ PLA; Molboolean;

    Sammanfattning : Cell signaling is mediated by signaling proteins that relay the signal in an intricate network of interactions before the signal is translated into a biological response. Short linear motifs (SLiMs) in intrinsically disordered regions of proteins serve as docking sites for protein interaction in all aspects of cell regulation including signal transduction. LÄS MER

  5. 9. 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

  7. 10. Signaling via Orexin Receptors : A Pharmacological Study

    Författare :Tomas Holmqvist; Jyrki Kukkonen; Karl Åkerman; Gunnar Flemström; Per Svenningsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; orexin; receptors; calcium; cAMP; adenylyl cyclases; Fysiologi; Physiology; Fysiologi;

    Sammanfattning : The orexin receptors are a pair of newly discovered G-protein coupled receptors which are activated by the neuropeptides orexins and play a role in sleep/vigilance, apetite/metabolism and neuroendocrine regulation. On a cellular level receptor activation results in, to name but a few effects, elevation of intracellular calcium and depolarisation. LÄS MER
