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 antigen (Ag) cross-presentation, dendritic cells (DCs) take up extracellular Ag and translocate them from the endosome to the cytosol for proteasomal degradation. The processed peptides can enter the conventional MHC I pathway. The molecules responsible for the translocation of Ag across the endosomal membrane into the cytosol are unknown. Here we demonstrate that heat shock protein 90 (HSP90) is critical for this step. Cross-presentation and -priming were decreased in both HSP90α-null DCs and mice. CD8α(+) DC apoptosis mediated by translocation of exogenous cytochrome c to the cytosol was also eliminated in HSP90α-null mice. Ag translocation into the cytosol was diminished in HSP90α-null DCs and in DCs treated with an HSP90 inhibitor. Internalized Ag was associated with HSP90 and translocated to the cytosol, a process abrogated by the HSP90 inhibitor. Ag within purified phagosomes was released in an HSP90-dependent manner. These results demonstrate the important role of HSP90 in cross-presentation by pulling endosomal Ag out into the cytosol.
