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

Tregs maintain immune tolerance through mechanisms tightly coupled to cellular metabolism. Whereas glycolysis supports migration of Tregs, lipid metabolism sustains their suppressive phenotype. Here, we identify SREBP1c as a central regulator of Treg immunobiology. Tregs from Srebp1c-deficient mice displayed impaired suppressive function, reduced frequencies in circulation and lymphoid tissues, and diminished expression of functional markers. These defects stemmed from intrinsic metabolic rewiring rather than systemic alterations, as both ex vivo Tregs (CD4+CD25hiFoxP3+) and in vitro-derived Tregs lacking Srebp1c were shifted toward glycolysis. Integrated transcriptomic and lipidomic analyses revealed that Srebp1c-deficient Tregs exhibited defective phospholipid remodeling, with an accumulation of lysophosphatidylcholines over phosphatidylcholines, which we attributed to enhanced cytosolic phospholipase A2 (cPLA2α) activity and disruption of the Lands cycle. Altered lipid composition impaired adenosine-mediated immunosuppression by reducing CD73 expression and extracellular adenosine generation. Accordingly, pharmacological inhibition of cPLA2α restored adenosine signaling, CD73 expression, and Treg suppressive capacity. Thus, by preserving phospholipid homeostasis, SREBP1c functions as an immunometabolic checkpoint that links lipid metabolism to adenosine-dependent Treg suppression.
