1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

ATP production through oxidative phosphorylation in the mitochondria is the most efficient way to provide energy to various energy-consuming activities of the neurons. These processes require a large amount of ATP molecules to be maintained. Of these, synaptic transmission is most energy consuming. Here we report that lactate transported through monocarboxylate transporters (MCTs) at excitatory synapses constitutively supports synaptic transmission, even under conditions in which a sufficient supply of glucose and intracellular ATP are present. We analyzed the effects of MCT inhibition on neuronal activities using whole-cell recordings in brain slices of rats in the nucleus of the solitary tract. MCT inhibitors (α-cyano-4-hydroxycinnamic acid (4-CIN), phloretin, and d-lactate) significantly decreased the amplitude of EPSCs without reducing release probability. Although 4-CIN significantly reduced currents mediated by heterologously expressed AMPA-Rs in oocytes (a novel finding in this study), the IC50 of the inhibitory effect on EPSC in brain slices was ∼3.8 times smaller than that on AMPA-R currents in oocytes. Removal of intracellular ATP significantly potentiated the inhibition of EPSC with 4-CIN in a manner that was counteracted by intracellular lactate addition. In addition, extracellular lactate rescued aglycemic suppression of EPSC, in a manner that was prevented by 4-CIN. Inhibition of MCTs also reduced NMDA-R-mediated EPSCs and, to a lesser extent, the IPSC. The reduction in EPSC amplitude by γ-d-glutamylglycine was enhanced by 4-CIN, suggesting also a decreased quantal content. We conclude that "on-site" astrocyte-neuron lactate transport to presynaptic and postsynaptic elements is necessary for the integrity of excitatory synaptic transmission.
