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

backgroundFactors responsible for myeloid-derived suppressor cell (MDSC) expansion and T-cell dysfunction during human immunodeficiency virus type 1 (HIV) infection are unknown. This study investigated the role of MDSCs during HIV infection.

methodsPeripheral blood mononuclear cells (PBMCs) were cultured with gp120 and infectious or inactivated HIV, with or without anti-interleukin 6 (IL-6) antibody. CD33(+), CD4(+), and CD8(+) cells were isolated from PBMCs and cocultured in the presence or absence of inducible nitric oxide synthase (iNOS), reactive oxygen species (ROS), and arginase 1 inhibitors. CD11b(+)CD33(+)CD14(+)HLA-DR(-/lo) MDSCs, phosphorylated STAT3 (pSTAT3), and CD4(+)CD25(+)FoxP3(+) cells were evaluated by flow cytometry. IL-6, interferon γ (IFN-γ), interleukin 10 (IL-10), and gp120 levels were quantified by an enzyme-linked immunosorbent assay.

resultsMDSCs expanded when PBMCs were exposed to infectious or inactivated HIV. Exposure to gp120 led to MDSC expansion, with increases in IL-6 levels and pSTAT3 expression. Anti-IL-6 abrogated MDSC expansion and pSTAT3 expression. gp120-expanded CD33(+) MDSCs inhibited IFN-γ release from autologous T cells, which was restored upon ROS and iNOS inhibition. gp120-expanded CD33(+) MDSCs increased IL-10 and CD4(+)CD25(+)FoxP3(+) regulatory T-cell levels in CD4(+) T-cell cocultures. Finally, high frequencies of MDSCs were present in HIV-infected persons, compared with healthy controls.

conclusionsThese findings demonstrate that HIV gp120 induces IL-6 and MDSC expansion, which contributes to immune suppression by modulating cytokine and cellular responses.
