Apolipoprotein E modulates immune activation by acting on the antigen-presenting cell.
Article in Immunology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 56 papers.
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
Apolipoprotein E (ApoE) is synthesized by a variety of cells including macrophages. These cells activate T lymphocytes by antigen presentation, while the T-cell cytokine, interferon-gamma, inhibits macrophage ApoE expression. ApoE inhibits T-cell proliferation in culture but its role in immune responses has been unclear. The ApoE-deficient (E0) mouse permits an evaluation of the immunological role of ApoE. We have analysed T-cell responses to an exogenous antigen (ovalbumin) and polyclonal mitogen (concanavalin A) in E0 and ApoE+/+ mice. Macrophages of E0 mice stimulated T-cell activation more effectively as antigen-presenting cells than macrophages from ApoE+/+ mice. Both proliferation and interferon-gamma secretion were enhanced in T cells activated in the context of antigen-presenting cells from E0 mice. Since the macrophage-T-cell interaction depends on interactions between cell surface molecules, we assessed the expression of such molecules after in vivo stimulation with interferon-gamma. This treatment caused an increased expression of the co-stimulatory surface proteins CD40 and CD80, and also of the major histocompatibility complex class II molecules I-Ab on macrophages of E0 mice compared with ApoE+/+. Our data suggest that ApoE inhibits T-cell activation by reducing the density of immune stimulatory proteins on antigen-presenting cells.
