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

Many intracellular pathogens evade the innate immune response in order to survive and proliferate within infected cells. We show that Porphyromonas gingivalis, an intracellular opportunistic pathogen, uses a nucleoside-diphosphate kinase (NDK) homolog to inhibit innate immune responses due to stimulation by extracellular ATP, which acts as a danger signal that binds to P2X7 receptors and induces activation of an inflammasome and caspase-1. Thus, infection of gingival epithelial cells (GECs) with wild-type P. gingivalis results in inhibition of ATP-induced caspase-1 activation. However, ndk-deficient P. gingivalis is less effective than wild-type P. gingivalis in reducing ATP-mediated caspase-1 activation and secretion of the pro-inflammatory cytokine, IL-1β, from infected GECs. Furthermore, P. gingivalis NDK modulates release of high-mobility group protein B1 (HMGB1), a pro-inflammatory danger signal, which remains associated with chromatin in healthy cells. Unexpectedly, infection with either wild-type or ndk-deficient P. gingivalis causes release of HMGB1 from the nucleus to the cytosol. But HMGB1 is released to the extracellular space when uninfected GECs are further stimulated with ATP, and there is more HMGB1 released from the cells when ATP-treated cells are infected with ndk-deficient mutant than wild-type P. gingivalis. Our results reveal that NDK plays a significant role in inhibiting P2X7-dependent inflammasome activation and HMGB1 release from infected GECs.
