Anti-Nectin4 monoclonal antibodies attenuate airway inflammation and epithelial barrier dysfunction in asthma.
Article in Frontiers in pharmacology, 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
Objective: Nectin4 is an epithelial cell-adhesion molecule that may be involved in airway inflammatory responses. However, the effects of Nectin4 targeting in asthma has not yet been investigated. Methods: Here we engineered anti-Nectin4 monoclonal antibody, N-1T1C8Ab or N-1T3H9Ab, their effects on airway epithelial dysfunction and inflammation. Dermatophagoides pteronyssinus 1 ( Results: Anti-Nectin4 antibody treatment restored epithelial barrier dysfunction and was associated with changes in IL-33-related, MyD88/IRAK, and Afadin/Rac1 signaling in NHBE cells. In the murine asthma model, administration of N-1T1C8Ab or N-1T3H9Ab reduced airway inflammation, airway resistance, and immune cell infiltration in bronchoalveolar lavage fluid. Histological analysis demonstrated decreased inflammatory cell infiltration, goblet cell hyperplasia, and fibrosis in lung tissues. Anti-Nectin4 antibody treatment was also associated with modulation of IL-33/MyD88-related signaling components. Conclusion: These findings indicate that anti-Nectin4 monoclonal antibodies attenuate airway inflammation and improve epithelial barrier function. Further preclinical studies are warranted to determine the potential of Nectin4 targeting in asthma.
