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

Endocannabinoids (eCBs) are feedback messengers in the nervous system that act at the presynaptic nerve terminal to inhibit transmitter release. Here we report that in brain slices from rat, eCBs are released from vasopressin (VP) neurons in the paraventricular nucleus of the hypothalamus following coincident bursts of presynaptic and postsynaptic spiking. eCBs transiently depress glutamate release from excitatory terminals and, in doing so, prevent the synapses from undergoing long-term depression (LTD). Specifically, we show that blockade of CB1 receptors unmasks LTD following coincident presynaptic and postsynaptic activity. This LTD is presynaptic in nature, but requires the release of the opioid peptide dynorphin from the postsynaptic neuron. Dynorphin release and subsequent LTD require the activation of postsynaptic metabotropic glutamate receptors (mGluRs). Our findings indicate that eCBs, by transiently depressing glutamate release, limit mGluR activation and indirectly gate release of dynorphin from the postsynaptic neuron. We propose that eCBs, in addition to their well described role in the rapid modulation of transmitter release from the nerve terminal, also regulate the release of other retrograde transmitters and thus encode for multiple temporal windows of synaptic plasticity.
