title: Direct and continuous electrochemical measurement of noradrenaline-induced nitric oxide production in C6 glioma cells.
abstract: 1. Nitric oxide (NO) production in C6 glioma cells was directly monitored in real time by electrochemical detection with a NO-specific biosensor. 2. We present here the first direct evidence that noradrenaline elicits long-lasting NO production in C6 cells pretreated with lipopolysaccharide and interferon-gamma, an effect blocked by NG-monomethyl-L-arginine, a NO synthase inhibitor. 3. This direct electrochemical measurement of glia-derived NO should facilitate our understanding of the kinetics of glial signaling in glia-glia and glia-neuron networks in the brain.
