Antibody S22019F Selectively Recognises KIR2DS1 and Enables Analysis of KIR2DS1
Article in HLA, 2026. 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
Killer cell immunoglobulin-like receptors (KIR) and their cognate HLA ligands regulate the functions of natural killer (NK) cells. However, extensive sequence homology within the KIR family limits the ability of monoclonal antibodies to selectively recognise individual receptors, and no KIR2DS1-specific reagent is available to date. Here, we comprehensively delineate the binding profile of the monoclonal antibody S22019F. Using Ba/F3 cells, NK cell clones, and primary NK cells, we demonstrate that S22019F selectively binds KIR2DS1. Moreover, functional assays reveal that binding of S22019F to KIR2DS1 is preserved upon activation by its HLA-C ligand. We further confirm that S22019F does not cross-react to KIR2DL3*005 allotypes and we extend its application to the analysis of KIR2DS1
