Obesity and type 2 diabetes in rats are associated with altered brain glycogen and amino-acid homeostasisHelle M Sickmann
Department of Pharmacology and Pharmacotherapy, Faculty of Pharmaceutical Sciences, University of Copenhagen, Copenhagen, Denmark
J Cereb Blood Flow Metab 30:1527-37. 2010..Glucose metabolism through the TCA cycle was more decreased than glycolytic activity. Furthermore, reduced glutamate-glutamine cycling was also observed in the obese and type 2 diabetic states...
Functional significance of brain glycogen in sustaining glutamatergic neurotransmissionHelle M Sickmann
Department of Pharmacology and Pharmacotherapy, Faculty of Pharmaceutical Sciences, University of Copenhagen, Copenhagen, Denmark
J Neurochem 109:80-6. 2009..Neurotransmitter release was affected by the presence of d-lactate indicating that glycogen derived energy is important not only in the astrocytic but also in the neuronal compartment...
Functional importance of the astrocytic glycogen-shunt and glycolysis for maintenance of an intact intra/extracellular glutamate gradientArne Schousboe
Faculty of Pharmaceutical Sciences, Department of Pharmacology and Pharmacotherapy, University of Copenhagen, Universitetsparken 2, 2100, Copenhagen, Denmark
Neurotox Res 18:94-9. 2010..It is argued that glycolytically derived energy in the form of ATP may be of particular functional importance in this context...
Energy substrates to support glutamatergic and GABAergic synaptic function: role of glycogen, glucose and lactateArne Schousboe
Department of Pharmacology and Pharmacotherapy, Faculty of Pharmaceutical Sciences, University of Copenhagen, Universitetsparken 2, DK 2100 Copenhagen, Denmark
Neurotox Res 12:263-8. 2007..Moreover, it should be noted that the amino acid neurotransmitters can be used as metabolic substrates. This requires pyruvate recycling, a process that is discussed as well...
Characterization of 1,4-dideoxy-1,4-imino-d-arabinitol (DAB) as an inhibitor of brain glycogen shunt activityAnne B Walls
Department of Pharmacology and Pharmacotherapy, Faculty of Pharmaceutical Sciences, University of Copenhagen, Copenhagen, Denmark
J Neurochem 105:1462-70. 2008..Based on the experimental findings, DAB can be used to evaluate glycogen shunt activity and its functional importance in intact brain tissue and cells at a concentration of 300-1000 muM and a pre-incubation period of 1 h...
Compartmentation of lactate originating from glycogen and glucose in cultured astrocytesHelle M Sickmann
Department of Pharmacology and Pharmacotherapy, Danish University of Pharmaceutical Sciences, DK-2100 Copenhagen, Denmark
Neurochem Res 30:1295-304. 2005..Moreover, it was found that lactate originating from glycogen is compartmentalized from that derived from glucose, which lends further support to a compartmentalized metabolism in astrocytes...
