The CD94/NKG2A-HLA-E Axis as a Target in Cancer Immunotherapy: A Critical Perspective.
Review in Clinical cancer research : an official journal of the American Association for Cancer Research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Successful clinical development of PD-1/PD-L1 and CTLA4 immune checkpoint blockers intensified the search for other potential targets for cancer immunotherapy. Among them, the CD94/NKG2A inhibitory receptor displayed by NK cell and T-cell subsets, which specifically interacts with the nonclassic HLA-E class I molecule, has attracted special attention. Here, we provide an overview of basic concepts on the CD94/NKG2A-HLA-E axis biology relevant in the framework of ongoing cancer immunotherapy approaches in different scenarios. First, the effectiveness of blocking the NKG2A-HLA-E interaction in vitro and in preclinical models as well as the presence of infiltrating NKG2A+ CD8+ T cells in some solid tumors has led to the generation of clinical-grade NKG2A-specific monoclonal antibodies, pioneered by monalizumab, currently tested in clinical trials. Second, controlling NKG2A expression by genetic engineering constitutes a promising approach to improve advanced adoptive NK cell-based immunotherapies. Challenges include identifying predictive biomarkers of responsiveness, selecting appropriate clinical settings, and optimizing combinatorial regimens.
