  1. 1. The role of gap junctions in coordination of intercellular Ca2+ signaling

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Emma Latron; [2023]
    Nyckelord :applied physics; biophysics; Calcium; MDCKII; Gap Junctions; signalling; Segmentation; Tillämpad fysik; Biofysik; Kalcium; MDCKII; Gap Junctions; signalering; segmentering;

    Sammanfattning : Calcium ions are one of the most versatile signalling molecules. They are essential tothe proper functioning of various cellular processes in many different types of cells.The calcium signals have been studied in the past using ratiometric dyes like Fura-2. LÄS MER

  3. 2. Factors and mechanisms associating the mobilisation of Ca2+ with the activation of the NLRP3 inflammasome : A systematic review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Maria Panagiota Theodorou; [2022]
    Nyckelord :;

    Sammanfattning : Inflammasomes are multiprotein complexes that play a critical role in the regulation of inflammation and the inflammatory responses against pathogens. NLRP3 (NOD-, LRR-and pyrin domain-containing protein 3) is among the molecules involved in the homonymous and well-studied NLRP3 inflammasome that accounts for the release of the pro-inflammatory cytokines interleukin (IL) 1-β and 18.

  4. 3. Role of TRPV1 channel and P2Y1 receptor in Ca2+ signalling in β-cells : A study by single cell microfluorometry

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Kalaiselvan Krishnan; [2011]
    Nyckelord :Insulin exocytosis; P2Y1; tolbutamide; ADPr; microfluorometry; Islets of langerhans; β-cells; calcium signaling; signal transduction.;

    Sammanfattning : Increase in the cytoplasmic Ca2+ concentration ([Ca2+]i) in the β-cells triggers insulin exocytosis. Among the Ca2+ channels present in the plasma membrane, the transient receptor potential (TRP) channels receptors are currently of great interest. LÄS MER

  5. 4. Thrombin receptor signalling in platelets: PAR1, but not PAR4, is rapidly desensitized

    Master-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Linda Haglund; [2009]
    Nyckelord :Nitric oxide; PAR1; PAR4; platelets; receptor desensitization;

    Sammanfattning : Platelets play a key role in primary haemostasis but are also related to the pathogenesis of arterial thrombosis. Thrombin is the most effective agonist inducing platelet activation. Human platelets express two G-protein coupled thrombin receptors (GPCRs), called protease activated receptor (PAR)1 and PAR4.

  7. 5. Administration of morphine and/or cocaine modulates the expression levels of genes related to plasticity mechanisms in rat hippocampus

    Magister-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Therés Larsson; [2008]
    Nyckelord :;

    Sammanfattning : Drugs of abuse regulate the expression of several genes involved in receptor regulation and signalling, transcription factors and cytoskeleton proteins. Due to its implication in long-term memory consolidation, rat hippocampus was selected to identify genes that are differently regulated by morphine and/or cocaine administration. LÄS MER
