    Inhibition of soluble epoxide hydrolase after oxygen-glucose deprivation in astrocytes stabilizes epoxyeicosatrienoic acids, which then augment the release of VEGF. Exposure of neurons to oxygen-glucose deprivation followed by the conditioned astrocyte medium increases neuronal phosphorylated Akt through VEGF receptor-2 signaling and leads to increased neuronal survival, thereby providing evidence of one way by which astrocytes can be leveraged for neuroprotection.

    Intracellular sodium and chloride levels are low in mature neurons. While chloride levels are believed to be much higher in developing neurons, it is assumed that sodium levels are low early in development. We find that sodium levels are relatively high in embryonic spinal neurons. Furthermore, we find that later in embryonic development sodium levels are reduced through the functional down-regulation of the NKCC1 transporter, and alteration of another unknown transporter (Na/K-ATPase and/or Transporter X). These results are important because the sodium gradient influences driving force for many ion transporters and will influence neuronal excitability.

  5. Acetate metabolism does not reflect astrocytic activity, contributes directly to GABA synthesis, and is increased by silent information regulator 1 activation

    Acetate is a poor substrate for energy generation and it also, at high concentrations (> 2 mmol/L), inhibits metabolism of glucose and of itself. Potassium depolarisation results in decreased use of acetate and decreased incorporation of acetate into glutamine showing that acetate metabolism does not necessarily reflect astrocytic activity. GABA is not only made via astrocytic glutamine, but acetate is converted as well directly to GABA in neurons. Acetate metabolism is likely regulated via acetylation of the metabolizing enzyme acetyl-CoA synthetase. Changes in acetate metabolism should be interpreted as modulation of metabolism through changes in cellular energetic status via altered enzyme acetylation levels rather than simply as a glial–neuronal adjustment of metabolic activity.
