Hide and seek: for HIV-infected CD4+ T cells, playing well comes with maturity.
Article in The Journal of clinical investigation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Antiretroviral therapy suppresses HIV replication but leaves a population of infected CD4+ T cells with integrated proviruses. While most of these proviruses contain defects, such as deletions, some intact proviruses persist and can reinitiate viral replication. In this issue of the JCI, Duette, Hiener, and colleagues performed a tour de force proviral landscape analysis on clinical samples collected over many years with in vitro functional assays. The researchers showed that effector memory CD4+ T cells provide partial sanctuary to intact proviruses from CD8+ T cells and this was associated with superior Nef-mediated MHC-I downregulation relative to less mature CD4+ T cell populations. This finding implicates differential immunoevasion as a cell-intrinsic property, influencing proviral persistence, and highlights Nef as a therapeutic target.
