  4. 4. Calcium signaling in astroglial cells. Noradrenergic effects and regulation

    Författare :Håkan Muyderman; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Astrocytes; Neurons; Noradrenaline; Glutamate; Fluorometry; Fura-2; Fluo-3; PBFI; Digital imaging; Voltage-patch-clamp; Whole-cell currents; Calcium; Potassium; Intercellular communication; Glutamate release; Neuron-glial interactions.;

    Sammanfattning : Astroglial cells are the most common cell type in the central nervous system and express a wide array of ion channels and neurotransmitter receptors. The cells organize into multicellular networks and exhibit a calcium-based excitability in which receptor-mediated calcium elevations propagate as intercellular waves over considerable distances.
