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

Host factors that promote or restrict human immunodeficiency virus (HIV) infection in human CD4+ T cells have not been comprehensively identified. We employed orthogonal genome-wide CRISPR activation (CRISPRa) and CRISPR knockout screens in primary CD4+ T cells to discover pro- and anti-HIV host factors systematically. Secondary pooled screens and individual perturbations validated high-confidence hits and revealed diverse mechanisms of action. CRISPRa uncovered multiple potent antiviral factors, including PI16, PPID, SHISA3, and ITM2A. PI16 interacts with host factors involved in HIV fusion and inhibits viral entry, whereas PPID (Cyp40), a paralog of the proviral cyclophilin CypA, binds capsid and reduces nuclear import of the HIV core. Structural modeling, evolutionary analyses, and targeted mutagenesis revealed domains and residues required for PPID-mediated HIV restriction, including non-human primate ortholog substitutions that enhance antiviral activity. Together, these data define the functional HIV-host interaction landscape in primary human T cells and uncover new mechanisms modulating infection.
