Anti-cancer effect of interleukin-2 fused to flagellin expressed by tumor-targeting Salmonella.
Article in Oncogene, 2025. 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
Interleukin-2 (IL2) treatment has been explored as a potent immunotherapy agent, particularly for cancers, due to its ability to stimulate T cell proliferation and activity. However, significant challenges and limitations are associated with IL2 treatment, including its short half-life, systemic toxicity and side effects, and limited efficacy in solid tumors. In this study, we deployed an attenuated Salmonella Gallinarum (SG), an avian-specific pathogen capable of targeting tumor tissue, to express and secrete the IL2 using a bacterial flagellum type 3 secretion system (T3SS). Since the T3SS is used for the secretion of flagellin monomers (FliC), DNA of the human IL2 gene was fused to the SG fliC gene so that the fusion proteins would be exported together. A superb anti-cancer effect was observed when the SG expressing and secreting the FliC-IL2 fusion protein was injected into a syngeneic tumor mouse model with CT26 colorectal cancer via the tail vein. Within the fusion protein, the FliC moiety led to a selective increase in MHCII
