The Potential Role of Expression of HLA-E and HLA-G in Organ Xenotransplantation.
Review in Xenotransplantation. 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
Xenotransplantation offers a promising solution to the shortage of human organs for transplantation but requires overcoming numerous immune responses-particularly those mediated by the innate immune system through natural killer (NK) cells and macrophages. This review examines advances demonstrating that the expression of human leukocyte antigen E (HLA-E) on porcine cells contributes to reduce cellular xenograft rejection. HLA-E expression partially inhibits both direct NK cell cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC), while also attenuating macrophage-mediated lysis. Furthermore, perfusion of transgenic porcine organs expressing HLA-E with human blood resulted in significantly less tissue damage compared to wild-type counterparts, thereby confirming the protective effect of HLA-E against innate immunity. Inhibition of NK cell activation can be further enhanced by co-expression of HLA-G and HLA-E. These findings confirm the potential of HLA-E and HLA-G expression as a complementary strategy in the design of immune-compatible porcine organs for clinical xenotransplantation.
