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

TRIM5 alpha is a host protein that can bind to incoming retroviral capsid (CA) and inhibit retroviruses in a species-specific manner. The CA protein of HIV-1 also interacts with high affinity to the host protein cyclophilin A (CypA). This binding has been shown to positively affect some early stage of the viral life cycle in human cells. However, the CypA/CA interaction also renders HIV-1 more susceptible to rhesus TRIM5 alpha (rhTRIM5 alpha) restriction. We find that the ability of old world monkey TRIM5 alpha genes to restrict HIV-1 in a CypA-dependent manner is widespread. On the other hand, we find that simian immunodeficiency viruses from tantalus monkeys (SIVagmTAN), is unlike HIV-1 in that CypA does not enhance the rhTRIM5 alpha restriction against the virus even though the CA of this virus, like HIV-1, does bind CypA. Mapping of the determinants for this phenotype by swapping regions on CA between SIVagmTAN and HIV-1 showed that when SIVagmTAN contains loops between helices 4/5 (4-5 loop) and 6/7 (6-7 loop) from HIV-1 CA, it becomes susceptible to the CypA-enhanced rhTRIM5 alpha restriction. Surprisingly, when SIVagmTAN contains either loop from HIV-1 CA, it gains sensitivity to TRIM5 alpha from species which originally have no effect on the wild-type virus. Moreover, we find that CypA/CA interaction occurs early after viral entry but the CypA-enhanced restriction mostly acts on the stage after reverse transcription.
