Endothelial nitric oxide synthase inhibits the development of autoimmune-mediated vasculitis in mice.
Article in Arthritis and rheumatism, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveMany different genes or mediators have been implicated in promoting the development of vasculitis, although little is known regarding the mechanisms that normally act to suppress lesion formation. Endothelial nitric oxide synthase (eNOS) has been shown to inhibit vascular inflammation in many different model systems, but its roles in the pathogenesis of vasculitis have not been elucidated. This study was undertaken to determine the functions of eNOS in the initiation and progression of vasculitic lesion formation.
methodsMRL/MpJ-Fas(lpr) mice lacking the gene for eNOS (Nos3(-/-) ) were generated and comprehensively evaluated and compared to controls with regard to the development of autoimmune disease, including vasculitic lesion formation and glomerulonephritis.
resultsNos3(-/-) MRL/MpJ-Fas(lpr) mice exhibited accelerated onset and increased incidence of renal vasculitis compared to Nos3(+/+) controls. In contrast, no significant differences in severity of glomerulonephritis were observed between groups. Vasculitis was also observed in other organs of eNOS-deficient mice, including in the lungs of several of these animals. Ultrastructural analyses of renal lesions revealed the presence of electron-dense deposits in affected arteries, and IgG, IgA, and C3 deposition was observed in some vessels in the kidneys of Nos3(-/-) mice. In addition, Nos3(-/-) MRL/MpJ-Fas(lp) mice showed increased levels of circulating IgG-IgA immune complexes at 20 weeks of age, compared to Nos3(+/+) MRL/MpJ-Fas(lpr) and Nos3(-/-) C57BL/6 mice.
conclusionThese findings strongly indicate that eNOS serves as a negative regulator of vasculitis in MRL/MpJ-Fas(lpr) mice and further suggest that NO produced by this enzyme may be critical for inhibiting lesion formation and vascular damage in human vasculitic diseases.
