Do active cerebral neurons really use lactate rather than glucose?

Chih, Ching-Ping, Lipton, Peter, Roberts, Eugene L·2001·Trends in Neurosciences

Abstract

Glucose has long been considered the substrate for neuronal energy metabolism in the brain. Recently, an alternative explanation of energy metabolism in the active brain, the astrocyte-neuron lactate shuttle hypothesis, has received attention. It suggests that during neural activity energy needs in glia are met by anaerobic glycolysis, whereas neuronal metabolism is fueled by lactate released from glia. In this article, we critically examine the evidence supporting this hypothesis and explain, from the perspective of enzyme kinetics and substrate availability, why neurons probably use ambient glucose, and not glial-derived lactate, as the major substrate during activity.

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?

  • The astrocyte-to-neuron lactate shuttle (ANLS) hypothesis has been quite controversial for a long time.

    “The ANLS hypothesis has been quite controversial for a long time (Chih et al., 2001; Gjedde and Marrett, 2001; Hertz, 2004; Mangia et al., 2011; Dienel, 2012, 2017; Bak and Walls, 2018; Barros and Weber, 2018; see also Dienel [2017] for strong arguments against ANLS at the tissue level).”

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.
