  1. 1. ATP Dynamics in Pancreatic α- and β-cells

    Författare :Jia Li; Anders Tengholm; Erik Gylfe; Hindrik Mulder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATP; Ca2 ; β-cell; α-cell; SERCA; SOCE; muscarinic receptor; insulin secretion; glucagon secretion; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Glucose metabolism in pancreatic α- and β-cells is believed to regulate secretion of glucagon and insulin, respectively. In β-cells, ATP links glucose metabolism to electrical activity and insulin secretion. LÄS MER

  3. 2. Endoplasmic reticulum function in dendrites and dendritic spines of hippocampal neurons

    Författare :Ai Na Ng; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endoplasmic reticulum; primary culture; dendritic spines; live cell imaging; STIM1; carbachol; store-operated calcium entry; 3; familial Alzheimer s disease; 5-dihyroxyphenyglycine;

    Sammanfattning : 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. LÄS MER

  4. 3. On the Generation of cAMP Oscillations and Regulation of the Ca2+ Store-operated Pathway in Pancreatic Islet α- and β-cells

    Författare :Geng Tian; Erik Gylfe; Anders Tengholm; Patrick Gilon; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cAMP; oscillations; adrenaline; GLP-1; phosphodiesterase; palmitate; STIM1; Orai1; store-operated calcium entry; insulin secretion; glucagon secretion; β-cell; α-cell; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : 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.
