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

The immunodeficiency disorder Wiskott-Aldrich syndrome (WAS) leads to life-threatening hematopoietic cell dysfunction. We used WAS protein (WASp)-deficient mice to analyze the in vivo efficacy of lentiviral (LV) vectors using either a viral-derived promoter, MND, or the human proximal WAS promoter (WS1.6) for human WASp expression. Transplantation of stem cells transduced with MND-huWASp LV resulted in sustained, endogenous levels of WASp in all hematopoietic lineages, progressive selection for WASp+ T, natural killer T and B cells, rescue of T-cell proliferation and cytokine production, and substantial restoration of marginal zone (MZ) B cells. In contrast, WS1.6-huWASp LV recipients exhibited subendogenous WASp expression in all cell types with only partial selection of WASp+ T cells and limited correction in MZ B-cell numbers. In parallel, WS1.6-huWASp LV recipients exhibited an altered B-cell compartment, including higher numbers of λ-light-chain+ naive B cells, development of self-reactive CD11c+FAS+ B cells, and evidence for spontaneous germinal center (GC) responses. These observations correlated with B-cell hyperactivity and increased titers of immunoglobulin (Ig)G2c autoantibodies, suggesting that partial gene correction may predispose toward autoimmunity. Our findings identify the advantages and disadvantages associated with each vector and suggest further clinical development of the MND-huWASp LV for a future clinical trial for WAS.
