Chromatin repression by PRC2 results in reduced gene expression driving key features of CD8 T cell exhaustion.

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.
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
Exhausted CD8 T cells result from chronic antigen stimulation and have reduced ability to clear disease. The epigenetic regulation of the dysfunctional phenotype of exhausted CD8 T cells is a promising avenue for therapies aimed at reversing or preventing CD8 T cell exhaustion. Here, utilizing in vitro and in vivo models, we show global increase of the repressive histone modification H3K27me3 in CD8 T cell exhaustion and increased gene expression of the EZH2 form of the PRC2 complex, which is responsible for H3K27me3 deposition. H3K27me3 correlated with decreased gene expression and localized to naive/memory T cell genes in CD8 T cell exhaustion. PRC2 inhibition increased expression of the naive/memory genes while reducing expression of key exhaustion genes. Further, we identified potential enhancers and transcription factors predicted to promote expression of the PRC2 subunits. Our study highlights the importance of the repressive epigenetic landscape of exhausted CD8 T cells as well as a novel role for PRC2 in T cell biology.
