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

In schistosomiasis japonica and mansoni, parasite eggs trapped in host liver elicit severe liver granulomatous inflammation that subsequently leads to periportal fibrosis, portal hypertension, haemorrhage or even death. Macrophages are critical for granuloma formation and the development of liver fibrosis during schistosomiasis. However, whether the aberrant regulation of macrophage autophagy has an effect on the development of liver immunopathology in schistosomiasis remains to be elucidated. In this study, we showed that Schistosoma japonicum (S. japonicum) egg antigen (SEA)-triggered macrophage autophagy limited the development of pathology in host liver. However, engagement of IL-7 receptor (IL-7R/CD127) on macrophages by S. japonicum infection-induced IL-7 significantly suppressed SEA-triggered macrophage autophagy, which led to an enhanced liver pathology. In addition, anti-IL-7 neutralizing antibody or anti-CD127 blocking antibody treatment increased macrophage autophagy and suppressed liver pathology. Finally, we demonstrated that IL-7 protects macrophage against SEA-induced autophagy through activation of AMP-activated protein kinase (AMPK). Our study reveals a novel role for IL-7 in macrophage autophagy and identifies AMPK as a novel downstream mediator of IL-7-IL-7R signalling and suggests that manipulation of macrophage autophagy by targeting IL-7-IL-7R signalling may have the potential to lead to improved treatment options for liver pathogenesis in schistosomiasis.
