Energy metabolism in glutamatergic neurons, GABAergic neurons and astrocytes in primary cultures

Hertz, Leif, Drejer, J�rgen, Schousboe, Arne·1988·Neurochemical Research

Abstract

Several aspects of energy metabolism (glucose utilization, lactate production, 14CO2 production from labeled glucose, glutamate or pyruvate, oxygen consumption and contents of ATP and phosphocreatine) were measured in cerebellar granule cells (glutamatergic) in primary cultures and compared with corresponding data for cerebral cortical neurons (mainly GABA-ergic) and astrocytes. Cerebellar granule cells and astrocytes were metabolically more active than cerebral cortical neurons. Glutamate which is utilized as a major metabolic fuel as astrocytes and, to a lesser extent, in cerebral cortical neurons, was virtually not oxidized in cerebellar granule cells.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Astrocytes can produce lactate from glucose.

    “Astrocytes can indeed produce lactate from glucose (Hertz et al., 1988; Magistretti et al., 1993), and this lactate production can be stimulated by glutamate and potassium, which become elevated during neuronal activity (Walz and Mukerji, 1988; Peng et al., 1994; Pellerin and Magistretti, 1996; Bittner et al., 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
