Adenosine receptor A2A deficiency in leukocytes increases arterial neointima formation in apolipoprotein E-deficient mice.
Article in Arteriosclerosis, thrombosis, and vascular biology, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
objectiveTo use the mice deficient in both adenosine receptor A(2A)(A(2A)R(-/-)) and apolipoprotein E (apoE(-/-)) to investigate the role of A(2A)R in mediating the interactions of leukocytes with injured arterial walls and the formation of arterial neointima induced by a guide wire. METHODS AND
resultsIn apoE(-/-) mice, A(2A)R deficiency increased the size of the arterial neointima in injured carotid arteries by 83%. Arterial neointima formation was also enhanced in chimeric mice that underwent bone marrow transplantation (these mice lacked A(2A)R in their bone marrow-derived cells). Epifluorescence intravital microscopy showed that neutrophil rolling and adherence to the injured arterial area were enhanced by 80% and 110% in A(2A)R(-/-)/apoE(-/-) mice, respectively. This phenomenon occurred even though the protein levels of homing molecules on A(2A)R-deficient neutrophils were unchanged from those of wild-type neutrophils. A(2A)R-deficient neutrophils exhibited an increase in the phosphorylation of p38 mitogen-activated protein kinase, P-selectin glycoprotein ligand-1 (PSGL-1) clustering, and the affinity of b(2) integrins. The inhibition of p38 phosphorylation abrogated the increased PSGL-1 clustering and beta(2) integrin affinity, thus reversing the increased homing ability of A(2A)R-deficient leukocytes.
conclusionA(2A)R plays a complex role in inflammation and tissue injury. The deficiency of A(2A)R enhances the homing ability of leukocytes and increases the formation of the arterial neointima after injury. A(2A)R antagonists are being tested for the treatment of neurodegenerative and other chronic diseases. An evaluation of the effect of A(2A)R antagonists on arterial restenosis after arterial angioplasty should be conducted.
