CD155 and its receptors in glioma: prospects for emerging immune checkpoint inhibitors.
Review in Acta neuropathologica communications, 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
Glioma is an aggressive brain malignancy characterized by a markedly immunosuppressive microenvironment and limited response to conventional treatments. CD155, also known as the poliovirus receptor, is frequently overexpressed in glioma and plays a key role in immune escape. By interacting with inhibitory receptors such as TIGIT and CD96, as well as the activating receptor CD226, CD155 modulates the tumor immune landscape. These interactions suppress the cytotoxic activity of T cells and natural killer (NK) cells while promoting immunoregulatory phenotypes, thereby impairing immune-mediated tumor cell elimination and supporting tumor progression. The balance among these receptor-ligand interactions is critical in determining immune outcomes. Targeting the CD155 axis has emerged as a potential therapeutic strategy. Approaches including monoclonal antibodies, bispecific antibodies, and chimeric antigen receptor (CAR)-engineered immune cells are being developed to counteract immune suppression and restore antitumor responses. This review summarizes the structural and functional features of CD155 and its associated receptors, examines their roles in glioma immune evasion, and discusses recent advances and challenges in developing therapies targeting this pathway. Modulation of CD155-related signaling may offer new opportunities to improve treatment outcomes in glioma.
