Identification of Epinastine as CD96/PVR inhibitor for cancer immunotherapy.
Article in BMC biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPoliovirus receptor (PVR) and its receptor system, including TIGIT, CD226, and CD96, play a pivotal role in orchestrating tumor immune evasion. Upon engagement with PVR on tumor cells, CD96 exerts inhibitory effects on the function of T cells and NK cells, thereby fostering tumor immune evasion. Therefore, screening of immune checkpoint inhibitors (ICIs) targeting the CD96/PVR pathway will provide promising candidates for tumor immunotherapy.
resultsIn this investigation, we employed MOE software to conduct virtual screening of small molecules from the FDA-approved drug library. Our results demonstrated that Epinastine exhibited high affinity for CD96, thereby effectively disrupting the interaction between CD96 and PVR. In vitro co-culture experiments further revealed that Epinastine effectively restored the ability of Jurkat cells to secrete IL-2. In the MC38 tumor-bearing model, Epinastine significantly enhanced the infiltration of T cells and NK cells into the tumor site and augmented their secretion of IFN-γ, leading to effective suppression of tumor growth.
conclusionsOur results demonstrated that the development of small molecule inhibitor Epinastine targeting CD96/PVR pathway, which proposed a promising strategy and drug candidate for cancer immunotherapy.
