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

backgroundHuman IL-32 is a polyfunctional cytokine that was initially reported to inhibit HIV-1 infection. However, recent data suggest that IL-32 may enhance HIV-1 replication by activating the HIV-1 primary targets, CD4 T-cells. Indeed, IL-32 is expressed in multiple isoforms, some of which are proinflammatory, whereas others are anti-inflammatory. SETTING AND

methodsHere, we aimed to determine the relative expression of IL-32 isoforms and to test their inflammatory nature and potential to induce HIV-1 production in latently infected cells from virologically suppressed HIV-infected individuals. IL-32 and other cytokines were quantified from plasma and supernatant of CD4 T-cells by ELISA. Transcripts of IL-32 isoforms were quantified by qRT-PCR in peripheral blood mononuclear cells. The impact of recombinant human IL-32 isoforms on HIV-1 transcription was assessed in CD4 T-cells from HIV-1cART individuals by qRT-PCR.

resultsAll IL-32 isoforms were significantly upregulated in HIV-1cART compared to HIV individuals with IL-32β representing the dominantly expressed isoform, mainly in T-cells and NK-cells. At the functional level, although IL-32γ induced typical proinflammatory cytokines (IL-6 and IFN-γ) in TCR-activated CD4 T-cells, IL-32α showed an anti-inflammatory profile by inducing IL-10 but not IL-6 or IFN-γ. However, IL-32β showed a dual phenotype by inducing both pro- and anti-inflammatory cytokines. Interestingly, consistent with its highly pro-inflammatory nature, IL-32γ, but not IL-32α or IL-32β, induced HIV-1 production in latently infected CD4 T-cells isolated from combined antiretroviral therapy-treated individuals.

conclusionsOur data report on the differential expression of IL-32 isoforms and highlight the potential role of IL-32, particularly the γ isoform, in fueling persistent inflammation and transcription of viral reservoir in HIV-1 infection.
