Sensitization Potential of the Major Soybean Allergen Gly m 4 and Its Cross-Reactivity with the Birch Pollen Allergen Bet v 1.
Article in International journal of molecular sciences, 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
The birch pollen allergen Bet v 1 is believed to be the main sensitizer among PR-10 allergens. Recent data have shown that some other PR-10 allergens also display sensitization activities, and Bet v 1-based immunotherapy is not effective for blocking allergic reactions to PR-10 proteins with low similarities to Bet v 1. Here, we investigated the sensitization potential of the major soybean allergen Gly m 4 and its cross-reactivity with Bet v 1. We demonstrated that Gly m 4 bound cholesterol and bile acids, including deoxycholic acid (DCA). Using qPCR, we showed that Gly m 4 induced the expression of genes encoding alarmins TSLP and IL-33 in intestinal-like Caco-2 cells; however, its fragments resulting from digestion by gastroduodenal enzymes or the DCA-bound Gly m 4 caused more pronounced gene upregulation. Using competitive ELISA, we demonstrated the low cross-reactivity of anti-Gly m 4 and anti-Bet v 1 IgG, raised in laboratory animals. Using mice allergy models with sensitization to birch or soybean allergens, we also showed a low cross-reactivity of Gly m 4- and Bet v 1-specific IgE, IgG1 and IgG2a. Thus, our findings support an assumption of the intrinsic sensitization capacity of Gly m 4 and the existence of Gly m 4-specific antibodies in sera of allergic patients.
