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

Matrix proteins (M) direct the process of assembly and budding of viruses belonging to the Mononegavirales order. Using the two-hybrid system, the amino-terminal part of vesicular stomatitis virus (VSV) M was shown to interact with dynamin pleckstrin homology domain. This interaction was confirmed by coimmunoprecipitation of both proteins in cells transfected by a plasmid encoding a c-myc-tagged dynamin and infected by VSV. A role for dynamin in the viral cycle (in addition to its role in virion endocytosis) was suggested by the fact that a late stage of the viral cycle was sensitive to dynasore. By alanine scanning, we identified a single mutation of M protein that abolished this interaction and reduced virus yield. The adaptation of mutant virus (M.L4A) occurred rapidly, allowing the isolation of revertants, among which the M protein, despite having an amino acid sequence distinct from that of the wild type, recovered a significant level of interaction with dynamin. This proved that the mutant phenotype was due to the loss of interaction between M and dynamin. The infectious cycle of the mutant virus M.L4A was blocked at a late stage, resulting in a quasi-absence of bullet-shaped viruses in the process of budding at the cell membrane. This was associated with an accumulation of nucleocapsids at the periphery of the cell and a different pattern of VSV glycoprotein localization. Finally, we showed that M-dynamin interaction affects clathrin-dependent endocytosis. Our study suggests that hijacking the endocytic pathway might be an important feature for enveloped virus assembly and budding at the plasma membrane.
