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

unlabelledHepatitis C virus (HCV) is a major cause of liver cirrhosis and hepatocellular carcinoma. Here we report that infection of hepatic cells by HCV stimulates nuclear factor kappa B (NFκB)-dependent production of thymic stromal lymphopoietin (TSLP). Hepatocyte-derived TSLP in turn conditions dendritic cells (DCs) to drive T-helper (Th)17 differentiation. The TSLP secreted by HCV-infected hepatoma cells is capable of activating human monocyte-derived DCs by up-regulating the expression of CD40, CD86, CCL17, CCL22, and CCL20 which are activating markers of DCs. In addition, the production of key cytokines for Th17 differentiation, transforming growth factor beta (TGF-β), interleukin (IL)-6, and IL-21, is enhanced by human monocytes upon coculture with HCV-infected cells. Importantly, the blockade of TSLP using neutralizing antibody prevented the activation and maturation of DCs as well as the production of Th17 differentiation cytokines. DC conditioning by TSLP secreted from HCV-infected cells activated naïve CD4+ T lymphocytes, resulting in Th17 differentiation. Furthermore, we can detect substantial levels of hepatocyte TSLP in fibrotic liver tissue from chronic HCV patients. Thus, blockade of TSLP released by HCV-infected hepatocytes may suppress the induction/maintenance of hepatic Th17 responses and halt the progression of chronic liver disease to fibrosis and liver failure.

conclusionHepatocyte-derived TSLP conditions DCs to drive Th17 differentiation. Treatment of TSLP neutralizing antibody in HCV-infected hepatocyte/DC coculture abrogates DC conditioning and thereby inhibits Th17 differentiation.
