    • Deletion of aquaporin-4 improves capillary blood flow distribution in brain edema 

      Bordoni, Luca; Thorén, Anna Elisabeth; Gutiérrez-Jiménez, Eugenio; Åbjørsbråten, Knut Sindre; Bjørnstad, Daniel Marelius; Tang, Wannan; Stern, Mette; Østergaard, Leif; Nagelhus, Erlend Arnulf; Frische, Sebastian; Ottersen, Ole Petter; Enger, Rune (Peer reviewed; Journal article, 2023)
      Brain edema is a feared complication to disorders and insults affecting the brain. It can be fatal if the increase in intracranial pressure is sufficiently large to cause brain herniation. Moreover, accruing evidence ...

    • Increased membrane Ca<sup>2+</sup> permeability drives astrocytic Ca<sup>2+</sup> dynamics during neuronal stimulation at excitatory synapses 

      Hjukse, Jarand Berg; Fernández de la Puebla, Mario; Vindedal, Gry Fluge; Sprengel, Rolf; Jensen, Vidar; Nagelhus, Erlend Arnulf; Tang, Wannan (Peer reviewed; Journal article, 2023)
      Astrocytes are intricately involved in the activity of neural circuits; however, their basic physiology of interacting with nearby neurons is not well established. Using two-photon imaging of neurons and astrocytes during ...

    • Loss of glutamate transporter eaat2a leads to aberrant neuronal excitability, recurrent epileptic seizures, and basal hypoactivity 

      Hotz, Adriana L.; Jamali, Ahmed; Rieser, Nicolas N.; Niklaus, Stephanie; Aydin, Ecem; Myren-Svelstad, Sverre; Lalla, Laetitia Noelle Patricia; Jurisch-Yaksi, Nathalie; Yaksi, Emre; Neuhauss, Stephan C.F. (Peer reviewed; Journal article, 2021)
      Astroglial excitatory amino acid transporter 2 (EAAT2, GLT-1, and SLC1A2) regulates the duration and extent of neuronal excitation by removing glutamate from the synaptic cleft. Hence, an impairment in EAAT2 function could ...
