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

Regulatory CD4(+) T cells (Treg) are important modulators of the immune response. Different types of Treg have been identified based on whether they are thymically derived (natural Treg) or induced in the periphery (adaptive Treg). We recently reported on an adaptive Treg phenotype that can be induced by the concomitant stimulation of human CD4(+) T cells through CD3 and the membrane complement regulator CD46. These complement (CD46)-induced regulatory T cells (cTreg) potently inhibit bystander T-cell proliferation through high-level secretion of IL-10. In addition, cTreg express granzyme B and exhibit cytotoxic effects toward activated effector T cells. Here, we analyzed the effect of cTreg on B-cell functions in a co-culture system. We found that cTreg enhance B-cell Ab production. This B-cell support is dependent on cell/cell contact as well as cTreg-derived IL-10. In addition, we show that T cells from a CD46-deficient patient are not capable of promoting B-cell responses, whereas CD46-deficient B cells have no intrinsic defect in Ig production. This finding may relate to a subset of CD46-deficient patients, who present with common variable immunodeficiency. Thus, the lack of cTreg function in optimizing B-cell responses could explain why some CD46-deficient patients develop common variable immunodeficiency.
