AFF3 maintains metabolic quiescence in naive CD8 T cells and prevents premature immune aging.
Article in JCI insight, 2026. 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
It is necessary for naive CD8 T cells to be actively maintained in a quiescent metabolic state in order to respond robustly to infection while avoiding inappropriate activation during homeostasis. With age, this quiescent state is lost and the CD8 T cell response to infection decreases. The factors regulating metabolic quiescence of CD8 T cells and how this regulation is lost during aging are not completely understood. Herein, we identify the transcription factor AFF3 as a regulator of metabolic quiescence in naive CD8 T cells. While naive AFF3-deficient CD8 T cells are more metabolically active prior to infection, they have reduced accumulation in response to viral infection, and this is correlated with a poor capacity to engage glycolysis. During aging in both murine and human CD8 T cells, AFF3 expression is decreased. In mice, this is associated with a loss of metabolic quiescence and reduced capacity to accumulate following infection. Our data highlight the role of metabolic regulation in CD8 T cell quiescence and identify a transcription factor that may be a target to reinvigorate CD8 T cell responses during aging.
