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

Mycobacterium tuberculosis (Mtb) evades host defense by hijacking and rupturing the phagosome. ESAT-6, a secreted virulence protein of Mtb, is known to be critical for phagosome rupture. However, the mechanism of ESAT-6-mediated disruption of the phagosomal membrane remains unknown. Using in vitro reconstitution, live-cell imaging, and numerical simulations, we discover that ESAT-6 polymerization forces remodeling and vesiculation of the phagosome-like compartment both in vitro and in vivo. Shallow insertion of ESAT-6 leads to tubular and bud-like deformations on the membrane facilitated by a reduction in membrane tension. Growing fibrils generate both radial and tangential forces causing local remodeling and shape transition of the membrane into buds. The ESAT-6-bound tensed membrane undergoes local changes in membrane curvature and lipid phase separation that assist the subsequent fission. Overall, the findings provide mechanistic insights into the long-standing question of phagosome disruption by Mtb for its escape.
