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

The stress-induced protease ClpP is required for virulence of the facultative intracellular pathogen Listeria monocytogenes. We previously found that in the absence of ClpP, the virulence of this pathogen was strongly reduced, mainly due to the decreased production of functional listeriolysin O (LLO), a major immunodominant virulence factor promoting intracellular growth. In this work, a clpP deletion mutant of L. monocytogenes was used to study the generation of anti-Listeria protective immunity. We found that ClpP is required for the intracellular growth of L. monocytogenes in resident macrophages in vivo. Mice infected with doses as high as 10(6) clpP mutant bacteria were not protected against a lethal challenge of wild-type bacteria and did not develop any detectable LLO-specific cytolytic T cells or antibodies, suggesting that the amount of LLO produced in infected mice under these conditions was too low to induce a specific immune response. However, in contrast to the results obtained with a mutant with a disrupted hly gene, this lack of protection was overcome by inoculation of very high infecting doses of clpP mutant bacteria (5 x 10(8)), thus producing sufficient amounts of LLO to stimulate anti-Listeria immunity. The role of ClpP was confirmed by showing that anti-Listeria immunity was restored in mice infected with a clpP-complemented mutant. These results indicate that the stress-induced serine protease ClpP is a potential target for modulating the presentation of protective antigens such as LLO and thereby the immune response against L. monocytogenes.
