Differential pharmacological behaviour of p38 inhibitors in regulating the LPS-induced TNF-α production in human and rat whole blood in vitro.

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
p38 inhibitors are potent TNF-α suppressors in LPS-stimulated human whole blood and promote efficacy in the rat adjuvant arthritis model. However, the anti-TNF-α activity of p38 inhibitors in rat whole blood has not been explored, preventing the establishment of a potential relation between in vitro and in vivo activity data in the same species. We have pharmacologically characterized a rat whole blood assay based on LPS stimulation. While p38 inhibitors showed good activity in the human assay, they failed to inhibit TNF-α in the rat whole blood assay. At high LPS concentration some compounds even potentiated TNF-α production in the rat assay, which could be reverted in the presence of the ERK pathway inhibitor U0126. Our results suggest that p38 contributes directly to TNF-α production in human whole blood while playing a negative regulatory role in rat blood which can be overridden by p38 inhibition in the presence of high stimulus concentration.
