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

backgroundThe blood-brain barrier (BBB) ensures the homeostasis of the central nervous system by regulating the composition of the brain interstitial fluid, required for proper brain function. Nonetheless, its properties are dynamic and susceptible to the influence of environmental factors acting through epigenetic mechanisms, among which are post-translational histone modifications. MAIN BODY: The activity of histone acetylases (HATs) and histone deacetylases (HDACs) on histone and non-histone substrates can alter gene transcription in brain endothelial cells, pericytes, astrocytes and microglia, leading to protective or detrimental effects on BBB integrity and function. These effects may range from the stabilization of intercellular junction proteins in brain endothelial cells to the modulation of neuroinflammation, with consequences on cognitive processes of memory and learning. Ultimately, the positive or negative outcome of HAT/HDAC activity is often context-dependent and varies across different pathologies, according to which corepressors or coactivators are recruited in intracellular signaling cascades, and their subsequent influence on gene expression.

conclusionsHATs/HDACs modulate the structural integrity and function of the BBB. Further studies in physiologically relevant BBB models are required, in order to provide greater mechanistic insight and overcome translational difficulties.
