TIM-3 signaling contributes to the suppressive capacity of Tregs from people with HIV on antiretroviral therapy.

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
TIM-3 expression is increased on peripheral regulatory T cells (Tregs) of virally suppressed persons with HIV-1 on antiretroviral therapy (PWH-ART). However, the relevance of TIM-3 expression in this setting is unclear. We used flow cytometry to evaluate the suppressive phenotype and signaling pathways in peripheral TIM-3- vs TIM-3+ Tregs in PWH-ART. TIM-3+ Tregs showed increased expression of IL-10 compared with persons without HIV-1. In addition, TIM-3+ Tregs displayed elevated signaling and activation, relative to TIM-3- Tregs from the same PWH-ART. Dramatically, TIM-3 blockade restrained the in vitro suppressive capacity of peripheral Tregs. Therefore, our data demonstrate not only that TIM-3 expression by Tregs is associated with an immunosuppressive response among PWH-ART, but also that TIM-3 contributes directly to the enhanced suppressive activity of Tregs in this setting.
