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

The rearrangement and expression of T cell receptor (TCR) gene segments occurs in a highly ordered fashion during thymic ontogeny of T lymphocytes. To study the regulation of gene rearrangement within the TCR alpha/delta locus, we generated transgenic mice that carry a germline human TCR delta minilocus that includes V delta 1, V delta 2, D delta 3, J delta 1, J delta 3, and C delta segments, and either contains or lacks the TCR delta enhancer. We found that the enhancer-positive construct rearranges stepwise, first V to D, and then V-D to J. Construct V-D rearrangement mimics a unique property of the endogenous TCR delta locus. V-D-J rearrangement is T cell specific, but is equivalent in alpha/beta and gamma/delta T lymphocytes. Thus, either there is no commitment to the alpha/beta and gamma/delta T cell lineages before TCR delta gene rearrangement, or if precommitment occurs, it does not operate directly on TCR delta gene cis-acting regulatory elements to control TCR delta gene rearrangement. Enhancer-negative mice display normal V to D rearrangement, but not V-D to J rearrangement. Thus, the V-D to J step is controlled by the enhancer, but the V to D step is controlled by separate elements. The enhancer apparently controls access to J delta 1 but not D delta 3, suggesting that a boundary between two independently regulated domains of the minilocus lies between these elements. Within the endogenous TCR alpha/delta locus, this boundary may represent the 5' end of a chromatin regulatory domain that is opened by the TCR delta enhancer during T cell development. The position of this boundary may explain the unique propensity of the TCR delta locus to undergo early V to D rearrangement. Our results indicate that the TCR delta enhancer performs a crucial targeting function to regulate TCR delta gene rearrangement during T cell development.
