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

Prostaglandin E2 (PGE2), an essential endogenous lipid mediator for normal physiological functions, can also act as an inflammatory mediator in pathological conditions. We determined whether Staphylococcus aureus lipoproteins are essential for inducing PGE2 secretion by immune cells and whether pattern recognition receptors mediate this process. PGE2 levels secreted by mouse peritoneal macrophages infected with the S. aureus isogenic mutant, lgt::ermB (Δlgt; deficient in lipoprotein maturation), decreased compared with those from macrophages infected with wild-type (WT) S. aureus. Experiments using toll-like receptors 2 (TLR2)-deficient, TLR4-deficient, and NLRP3-deficient mice indicated that these 3 proteins are involved in macrophage PGE2 secretion in response to S. aureus, and lipoproteins were essential for S. aureus invasion and survival within macrophages. Inhibition of endogenous PGE2 synthesis had no effect on bacterial invasion. Exogenous PGE2 inhibited phagocytosis in the WT S. aureus and its isogenic mutant but increased intracellular killing accompanied by enhanced IL-1β secretion. Our data demonstrate that S. aureus can induce macrophage TLR/mitogen-activated protein kinase/NF-κB signaling and that PGE2 treatment upregulates NLRP3/caspase-1 signaling activation. Thus, macrophage PGE2 secretion after S. aureus infection depends on bacterial lipoprotein maturation and macrophage receptors TLR2, TLR4, and NLRP3. Moreover, exogenous PGE2 regulates S. aureus-induced macrophage activation through TLRs and NLRP3 inflammasome signaling.
