Expansion of invariant natural killer T cells from systemic lupus erythematosus patients by alpha-Galactosylceramide and IL-15.
Article in PloS one, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
CD1d-restricted invariant natural killer T cells (iNKT cells) may play an important role in the pathogenesis of systemic lupus erythematosus (SLE). Interleukin (IL)-15 is a pro-inflammatory cytokine which is over-expressed in SLE patients. In the present study, we investigated the iNKT cell expansion of mononuclear cells (MNCs) from SLE patients following 10 days' culture with α-galactosylceramide (α-Galcer) and /or IL-15. We sought to determine the phenotypic and functional characteristics of the expanded iNKT cells compared to healthy controls and correlated with disease activity. We observed that 1. The percentages of Vα24+/Vβ11+ iNKT cells following 10-day incubation was lower in SLE groups compared to controls; 2. The percentages and absolute numbers of Vα24+/Vβ11+ iNKT cells were expanded by α-galactosylceramide (α-Galcer), and further enhanced with IL-15 in SLE patient, but the effect of IL-15 was much lower than controls; 3.IL-15 +α-Galcer expanded CD3+/CD56+ NKT-like cells from SLE patients, especially with active disease 4. The CD161+ Vα24+/Vβ11+ iNKT cells in SLE were more responsive to α-Galcer stimulation than the CD161- counterpart; 5. IL-15 decreased apoptosis of α-Galcer activated SLE iNKT cells; 6. IL-15 enhanced CD69, CD1d and CD11a expression on α-Galcer treated iNKT cells; 7. The IL-4 production of iNKT cells was decreased in SLE patients compared to controls; 8. IL-15 increased IFN-γ and IL-4 production of SLE iNKT cells; 8. IL-15 failed to augment the ability of iNKT cells to aid NK-mediated K562 cytolysis in SLE patients; 9. CD161 positivity, granzyme B and perforin expression of α-Galcer+IL-15 expanded iNKT cells correlated with C3 levels in SLE patients. Taken together, our results demonstrated numeric and functional deficiency of iNKT cells and their response to IL-15 in SLE patients. Our finding may provide insight for using adoptive iNKT cell therapy in autoimmune diseases.
