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

Aberrant autoantibody production is characteristic of systemic lupus erythematosus (SLE), but follicular regulatory T (TFR) cells can potentially suppress this abnormality. We investigate functional changes in TFR cells from SLE patients. Circulating TFR cells were collected from 19 SLE patients and 14 healthy controls (HC) to compare molecular expression and in-vitro suppressive capacity of follicular helper T (TFH) cell proliferation. To reveal the stability of forkhead box protein 3 (FoxP3) in TFR, pyrosequencing of conserved non-coding sequence (CNS) 2 at the FoxP3 gene locus was performed. We then tested interleukin (IL)-2 in SLE-TFR cells to check restoration of suppressor function. Programmed cell death 1 (PD-1) expression in SLE-TFR cells was positively correlated with anti-DNA antibody levels and disease activity. These cells had impaired suppressive function for TFH cells with decreased expression of suppression mediators FoxP3, cytotoxic T lymphocyte antigen 4 (CTLA-4) and IL-2 receptor alpha (IL-2Rα). Pyrosequencing identified hyper-methylation in CNS2 region of SLE-TFR cells comparing to HC. With in-vitro IL-2 stimulation, PD-1 expression of TFR cells significantly decreased, together with increased expression of FoxP3 and CTLA-4, especially at a low dose. Thus, SLE-TFR cells have functionally defective to TFH suppression, but low-dose IL-2 therapy might be useful to restore this ability.
