Insulin Antagonizes LPS-Induced Inflammatory Responses by Activating SR-A1/ERK Axis in Macrophages.

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
Insulin is a key regulator of metabolism and inflammation in the body. However, the mechanism of the anti-inflammatory effect of insulin is not fully understood. In the present study, we investigated the role of the class A1 scavenger receptor (SR-A1), a prototypic member of the pattern recognition receptor family, in the insulin-mediated suppression of inflammatory responses in macrophages. Our murine in vivo studies show that insulin can attenuate lipopolysaccharide (LPS)-induced endotoxemia in a SR-A1-dependent manner, and this was consistent with our in vitro results which demonstrate that the SR-A1 is necessary for insulin to antagonize the LPS-induced inflammatory responses in macrophages. The effect of SR-A1 on the anti-inflammatory action of insulin might be associated with the activation of the extracellular signal-regulated kinases (ERK) signaling pathway in macrophages. Insulin could inhibit macrophage polarization to a pro-inflammatory phenotype via the SR-A1/ERK cascade. Collectively, our results suggest that SR-A1 may be a pivotal element for the anti-inflammation effect of insulin in macrophages.
