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

T cells have emerged as a therapeutically-relevant target for ex vivo gene delivery and editing. However, most commercially available reagents cannot transfect T cells and designing cationic polymers for non-viral gene delivery to T cells has resulted in moderate success. Here, we assess various barriers to successful gene transfer in the Jurkat human T cell line and primary human T cells. Using two polymers previously developed by our group, we show that uptake is one barrier to gene delivery in primary human T cells but is not predictive of successful gene delivery. We then probe intracellular pathways for barriers to gene transfer including endosomal acidification, autophagy, and immune sensing pathways. We find that endosomal acidification is slower and not as robust in human T cells compared to the model HeLa human cell line commonly used to evaluate cationic polymers for gene delivery. These studies inform the future design of cationic polymers for non-viral gene delivery to T cells, specifically, to rely on alternative endosomal release mechanisms rather than on pH-triggered release.
