  4. 3. Spatial regulation of membrane receptor signaling using DNA origami

    Författare :Trixy Fang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Juxtracrine signaling between apposing membrane receptors and ligands is an important class of intercellular communication. Much focus has been directed towards studying the biochemical interactions between receptors and ligands, their surface expression levels and signaling activities for driving downstream signaling processes.

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

    Författare :Håkan Muyderman; Göteborgs universitet; []
    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.
