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

Neuromodulators such as monoamines assure essential brain functions, but relatively little is known about their mechanism of release. While recent work has advanced our knowledge of active zone architecture in dopamine axons, release machinery within the synaptic vesicle (SV) remains poorly understood. Here, we address differences between the release of monoamines and synaptic transmitters by comparing the composition of SVs that contain the vesicular monoamine transporter 2 (VMAT2) versus vesicular glutamate transporter 2 (VGLUT2). Previous work revealed that these SVs differ in frequency dependence, recycling kinetics, and biogenesis. We now find differences in the abundance and isoform expression of many SV protein families and validate these differences in primary neurons and brain tissue. Functional analysis after heterologous expression in hippocampal neurons shows that loss of differentially expressed SCAMP5 selectively impairs the recycling of VGLUT2 SVs, sparing vesicles targeted by VMAT2 in the same neuronal population. These findings provide insights into the molecular diversity of SVs and mechanisms of dopamine release.
