Targeted nuclear degranulation of neutrophils promotes the progression of pneumonia in ulcerative colitis.
Article in Precision clinical medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Background: Both intestinal and pulmonary systems are parts of the mucosal immune system, comprising ∼80% of all immune cells. These immune cells migrate or are transported between various mucosal tissues to maintain tissue homeostasis. Methods: In this study, we isolated neutrophils from the peripheral blood of patients and utilized immunofluorescence, flow cytometry, and Western blotting to confirm the incidence of "nucleus-directed degranulation" Result: In this study, we found that among patients with ulcerative colitis, the migration of neutrophils with "targeted nuclear degranulation" from the intestinal mucosa to the lungs significantly exacerbates lung inflammation during pulmonary infections. Notably, patients with ulcerative colitis exhibited a higher abundance of neutrophils with targeted nuclear degranulation. Using DSS mice, we observed that neutrophils with targeted nuclear degranulation from the intestinal mucosa migrated to the lung and underwent activation during pulmonary infections. These neutrophils rapidly released a high amount of neutrophil extracellular traps to mediate the progression of lung inflammation. Alterations in the neutrophil cytoskeleton and its interaction with the nuclear membrane represent the primary mechanisms underlying targeted nuclear degranulation. Conclusion: This study revealed that neutrophils accelerate lung inflammation progression in colitis, offering new insights and potential treatment targets for lung infections for patients with colitis.
