摘要
The possible interference of nitric oxide (NO) in glucose metabolism was studied in activated astrocytes. Lipopolysaccharide (LPS) treatment triggered a NO-mediated increase in glucose consumption and lactate production, suggesting an enhanced rate of glycolysis. Active glycogen synthesis was also observed after LPS treatment, but NO synthase inhibition was unable to prevent this effect. These results strongly suggest that endogenously-formed NO stimulates glycolysis through a glycogenolysis-independent mechanism in astrocytes. (C) 2002 Elsevier Science B.V. All rights reserved.
