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

aimExperimental autoimmune encephalomyelitis (EAE) is a CD4(+)-mediated autoimmune pathology of the central nervous system (CNS) that is used as a model for the study of the human neuroinflammatory disease, multiple sclerosis. During the development of EAE, auto-reactive Th1 and Th17 CD4(+) T cells infiltrate the CNS promoting inflammatory cells recruitment, focal inflammation and tissue destruction. In this sense, statins, agents used to lower lipid levels, have recently shown to exert interesting immunomodulatory function. In fact, statins promote a bias towards a Th2 response, which ameliorates the clinical outcome of EAE. Additionally, simvastatin can inhibit Th17 differentiation. However, many other effects exerted on the immune system by statins have yet to be clarified, in particular during neuroinflammation. Thus, the aim of this study was to investigate the effects of simvastatin on the development of experimental autoimmune encephalomyelitis.

methodsMice were immunized with MOG(35-55) and EAE severity was assessed daily and scored using a clinical scale. Cytokine secretion by mononuclear cells infiltrating the CNS was evaluated by flow cytometry.

resultsSimvastatin (5 mg/kg/day) improved clinical outcome, induced an increase in TGF-β mRNA expression and inhibited IL-6, IL-12p40, IL-12p70, RANTES and MIP-1β secretion (p < 0.05). This was accompanied by a significant decrease in CNS inflammatory mononuclear cell infiltration, with reduced frequencies of both Th1 and Th17 cells. Simvastatin inhibited the proliferation of T lymphocytes co-cultured with primary microglial cells.

conclusionsSimvastatin treatment promotes EAE clinical amelioration by inhibiting T cell proliferation and CNS infiltration by pathogenic Th1 and Th17 cells.
