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

Regenerative medicine is a rapidly expanding field harnessing human pluripotent stem cell (hPSC)-derived cells and tissues to treat many diseases, including type 1 diabetes. However, graft immune protection remains a key challenge. Chimeric antigen receptor (CAR) technology confers new specificities to effector T cells and immunosuppressive regulatory T cells (Tregs). One challenge in CAR design is identifying target molecules unique to the cells of interest. Here, we employ combinatorial genetic engineering to confer CAR-Treg-mediated localized immune protection to stem cell-derived cells. We engineered hPSCs to express truncated epidermal growth factor receptor (EGFRt), a biologically inert and generalizable target for CAR-Treg homing and activation, and generated CAR-Tregs recognizing EGFRt. Strikingly, CAR-Tregs suppressed innate and adaptive immune responses in vitro and prevented EGFRt-hPSC-derived pancreatic beta-like cell (sBC [stem cell-derived beta cell]) graft immune destruction in vivo. Collectively, we provide proof of concept that hPSCs and Tregs can be co-engineered to protect hPSC-derived cells from immune rejection upon transplantation.
