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

Long-term synaptic plasticity in the hippocampus is thought to underlie the formation of certain forms of memory, including spatial memory. The early phase of long-term synaptic potentiation and synaptic depression depends on post-translational modifications of synaptic proteins, while protein synthesis is also required for the late-phase of both forms of synaptic plasticity (L-LTP and L-LTD). Numerous pieces of evidence show a role for different types of proteases in synaptic plasticity, further increasing the diversity of mechanisms involved in the regulation of the intracellular and extracellular protein content. The cleavage of extracellular proteins is coupled to changes in postsynaptic intracellular mechanisms, and additional alterations in this compartment result from the protease-mediated targeting of intracellular proteins. Both mechanisms contribute to initiate signaling cascades that drive downstream pathways coupled to synaptic plasticity. In this review we summarize the evidence pointing to a role for extracellular and intracellular proteases, with distinct specificities, in synaptic plasticity. Where in the cells the proteases are located, and how they are regulated is also discussed. The combined actions of proteases and translation mechanisms contribute to a tight control of the synaptic proteome relevant for long-term synaptic potentiation and synaptic depression in the hippocampus. Additional studies are required to elucidate the mechanisms whereby these changes in the synaptic proteome are related with plasticity phenomena.
