HIV-1 Vpu protein antagonizes innate restriction factor BST-2 via lipid-embedded helix-helix interactions.
Article in The Journal of biological chemistry, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 77 papers, 1 of them a synthesis that pooled 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.
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 Vpu protein of HIV-1 antagonizes BST-2 (tetherin), a broad spectrum effector of the innate immune response to viral infection, by an intermolecular interaction that maps genetically to the α-helical transmembrane domains (TMDs) of each protein. Here we utilize NMR spectroscopy to describe key features of the helix-helix pairing that underlies this interaction. The antagonism of BST-2 involves a sequence of three alanines and a tryptophan spaced at four residue intervals within the Vpu TMD helix. Responsiveness to Vpu involves bulky hydrophobic residues in the C-terminal region of the BST-2 TMD helix that likely fit between the alanines on the interactive face of Vpu. These aspects of Vpu and BST-2 form an anti-parallel, lipid-embedded helix-helix interface. Changes in human BST-2 that mimic sequences found in nonhuman primate orthologs unresponsive to Vpu change the tilt angle of the TMD in the lipid bilayer without abrogating its intrinsic ability to interact with Vpu. These data explain the mechanism by which HIV-1 evades a key aspect of innate immunity and the species specificity of Vpu using an anti-parallel helix-helix packing model.
