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

Human immunodeficiency virus (HIV) replication in the major natural target cells, CD4+ T lymphocytes and macrophages, is parallel in many aspects of the virus life cycle. However, it differs as to viral assembly and budding, which take place on plasma membranes in T cells and on endosomal membranes in macrophages. It has been postulated that cell type-specific host factors may aid in directing viral assembly to distinct destinations. In this study we defined annexin 2 (Anx2) as a novel HIV Gag binding partner in macrophages. Anx2-Gag binding was confined to productively infected macrophages and was not detected in quiescently infected monocyte-derived macrophages (MDM) in which an HIV replication block was mapped to the late stages of the viral life cycle (A. V. Albright, R. M. Vos, and F. Gonzalez-Scarano, Virology 325:328-339, 2004). We demonstrate that the Anx2-Gag interaction likely occurs at the limiting membranes of late endosomes/multivesicular bodies and that Anx2 depletion is associated with a significant decline in the infectivity of released virions; this coincided with incomplete Gag processing and inefficient incorporation of CD63. Cumulatively, our data suggest that Anx2 is essential for the proper assembly of HIV in MDM.
