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

Although the extracellular matrix plays an important role in regulating use-dependent synaptic plasticity, the underlying molecular mechanisms are poorly understood. Here we examined the synaptic function of hyaluronic acid (HA), a major component of the extracellular matrix. Enzymatic removal of HA with hyaluronidase reduced nifedipine-sensitive whole-cell Ca(2+) currents, decreased Ca(2+) transients mediated by L-type voltage-dependent Ca(2+) channels (L-VDCCs) in postsynaptic dendritic shafts and spines, and abolished an L-VDCC-dependent component of long-term potentiation (LTP) at the CA3-CA1 synapses in the hippocampus. Adding exogenous HA, either by bath perfusion or via local delivery near recorded synapses, completely rescued this LTP component. In a heterologous expression system, exogenous HA rapidly increased currents mediated by Ca(v)1.2, but not Ca(v)1.3, subunit-containing L-VDCCs, whereas intrahippocampal injection of hyaluronidase impaired contextual fear conditioning. Our observations unveil a previously unrecognized mechanism by which the perisynaptic extracellular matrix influences use-dependent synaptic plasticity through regulation of dendritic Ca(2+) channels.
