  1. 1. The involvement of calcium and membrane fusion events in neutrophil secretion and respiratory burst

    Detta är en avhandling från Göteborg

    Författare :Daniel Granfeldt; Göteborgs universitet.; Gothenburg University.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; calcium; regulated secretion; membrane fusion; SOC; arachidonic acid; intracellular fusion; oxygen free radicals; phagocytosis;

    Sammanfattning : Neutrophil granulocytes play an important role in host defence during the early stages of microbial infection. The neutrophils have to leave the blood stream and migrate out into the tissue where they are able to phagocytose and kill microbes as well as dispose of cell debris from damaged tissues. LÄS MER

  2. 2. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation

    Detta är en avhandling från Sölvegatan 19, S223 62 Lund

    Författare :Maria Gomez; Lund University.; Lunds universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; verapamil; tissue culture; portal vein; patch-clamp; calcium; spermidine; spermine; polyamines; excitation-contraction; smooth muscle; calcium channel; ionomycin.; Physiology; Fysiologi;

    Sammanfattning : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. LÄS MER

  3. 3. Calcium and Phospholipases in Orexin Receptor Signaling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lisa Johansson; Uppsala universitet.; [2008]
    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).

  4. 4. Intracellular components involved in parathyroid sensing of extracellular calcium

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Isaac G. Onyango; Uppsala universitet.; [1999]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Parathyroid hormone; secretion; Src kinase; ERK; PI 3-kinase; PKC; extracellular calcium; parathyroid cell; Biokemi; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : Parathyroid glands are the primary regulator of extracellular calcium ([Ca2+]e). Ca2+ plays a key role in many fundamental biological processes and is also an essential structural component of the skeleton. The parathyroid chief cells detect small changes in [Ca2+]e and respond by altering the secretion of parathyroid hormone (PTH). LÄS MER

  5. 5. Calcium calmodulin-dependent protein kinase signal transduction in cerebral arteries

    Detta är en avhandling från Department of Clinical Sciences, Lund University

    Författare :Roya Waldsee; Lund University.; Lunds universitet.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CAMK; Ednothelin receptors; Calcium; gene regulation;

    Sammanfattning : Cerebral arteries participate actively in the response that follows an episode of cerebral ischemia in man and rat. It has been shown that the vascular endothelin receptor expression is increased in stroke and organ culture. LÄS MER
