1. On the Generation of cAMP Oscillations and Regulation of the Ca2+ Store-operated Pathway in Pancreatic Islet α- and β-cells
Abstract : Insulin and glucagon are released in pulses from pancreatic β- and α-cells, respectively. Both cell types are electrically excitable, and elevation of the cytoplasmic Ca2+ concentration ([Ca2+]i) due to depolarization with voltage-dependent entry of the cation is the main trigger of hormone secretion.

2. Endoplasmic reticulum function in dendrites and dendritic spines of hippocampal neurons
Abstract : In the hippocampus, dendritic spines are compartmentalized postsynaptic micro-domains in the excitatory synapse. Subsets of bigger and mushroom-shaped hippocampal dendritic spines contain tubules and cisterns of endoplasmic reticulum (ER) that are connected to the soma and dendrites of the neuron. READ MORE

3. Functional assays for the diagnosis of primary defects in lymphocyte cytotoxicity
Abstract : Cytotoxic lymphocytes encompass natural killer (NK) cells and cytotoxic T lymphocytes (CTL). These cells detect and kill virus-infected as well as malignant cells. Primary defects in lymphocyte cytotoxicity are associated with development of a hyperinflammatory syndrome termed hemophagocytic lymphohistiocytosis (HLH). READ MORE

4. Exploring the interactome of EF-hand proteins
Abstract : EF-hand proteins are central in many cellular processes being the main group of Ca2+-sensing and buffering proteins in the cell. In the work presented in this thesis we study ligand interactions of three EF-hand proteins; calmodulin, calbindin D28k and secretagogin. READ MORE

5. New insights in parathyroid hormone secretion : with focus on exocytosis and calcium signaling
Abstract : The parathyroid is distinguished from other endocrine systems since its primary stimuli inhibit hormone secretion. It is generally considered that extracellular Ca2+ binds to a membrane receptor (calcium sensing receptor, or CaSR), and via second messengers modulate parathyroid hormone (PTH) secretion. READ MORE
