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

Identifying T-cell receptors (TCRs) that bind tumor-associated antigens (TAAs) with optimal affinity is a key bottleneck in the development of adoptive T-cell therapy of cancer. TAAs are unmutated self proteins, and T cells bearing high-affinity TCRs specific for such antigens are commonly deleted in the thymus. To identify optimal-affinity TCRs, we generated antigen-negative humanized mice with a diverse human TCR repertoire restricted to the human leukocyte antigen (HLA) A*02:01 (ref. 3). These mice were immunized with human TAAs, for which they are not tolerant, allowing induction of CD8⁺ T cells with optimal-affinity TCRs. We isolate TCRs specific for the cancer/testis (CT) antigen MAGE-A1 (ref. 4) and show that two of them have an anti-tumor effect in vivo. By comparison, human-derived TCRs have lower affinity and do not mediate substantial therapeutic effects. We also identify optimal-affinity TCRs specific for the CT antigen NY-ESO. Our humanized mouse model provides a useful tool for the generation of optimal-affinity TCRs for T-cell therapy.
