The phospholipid profile of T cells shapes ACSL4 dependency and ferroptosis sensitivity of naive, effector, and memory T cells.

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
Iron-dependent phospholipid (PL) peroxidation, which is reduced by glutathione peroxidase 4, is recognized as the hallmark of cells undergoing ferroptosis. Although studies have attempted to elucidate the molecular mechanisms underlying ferroptosis in cancer cells, the regulation of ferroptosis in effector and memory T cells remains largely unknown. Here, using genome-wide CRISPR-Cas9 knockout screens, we demonstrate that acyl-CoA synthetase long-chain family member 4 (ACSL4) is the predominant ferroptosis inducer in primary T cells cultured in vitro, while other identified iron- and lipid metabolism-related genes only slightly modulate their sensitivity to ferroptosis. However, ACSL4 dependency relies on the PL composition of the cells. In vitro cultured T cells treated with polyunsaturated fatty acids (PUFAs), as well as effector CD8
