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

Major histocompatibility complex class I (MHCI) molecules modulate activity-dependent refinement and plasticity. We found that MHCI also negatively regulates the density and function of cortical synapses during their initial establishment both in vitro and in vivo. MHCI molecules are expressed on cortical neurons before and during synaptogenesis. In vitro, decreasing surface MHCI (sMHCI) on neurons increased glutamatergic and GABAergic synapse density, whereas overexpression decreased it. In vivo, synapse density was higher throughout development in β2m(-/-) mice. MHCI also negatively regulated the strength of excitatory, but not inhibitory, synapses and controlled the balance of excitation and inhibition onto cortical neurons. sMHCI levels were modulated by activity and were necessary for activity to negatively regulate glutamatergic synapse density. Finally, acute changes in sMHCI and activity altered synapse density exclusively during early postnatal development. These results identify a previously unknown function for immune proteins in the negative regulation of the initial establishment and function of cortical connections.
