THP-1 Macrophages Limit Neutrophil Transendothelial Migration in a Model Infection.
Article in Cellular and molecular bioengineering, 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
Introduction: Dysregulated neutrophil function plays a significant role in the pathology of infections, cancer, cardiovascular diseases, and autoimmune disorders. Neutrophil activity is influenced by various cell populations, including macrophages, which are crucial regulators. However, the exact role of human macrophages in controlling neutrophil function remains unclear due to a scarcity of studies utilizing human cells in physiologically relevant models. Methods: We adapted our "Infection-on-a-Chip" microfluidic device to incorporate macrophages within the collagen extracellular matrix, allowing for the study of interactions between human neutrophils and macrophages in a context that mimics in vivo conditions. The integration of THP-1 macrophages was optimized and their effect on the endothelial lumen was characterized, focusing on permeability and structural integrity. The device was then employed to examine the influence of macrophages on neutrophil response to infection with the bacterial pathogen Results: Integration of THP-1 macrophages into the microfluidic device was successfully optimized, showing no increase in endothelial permeability or structural damage. The presence of macrophages was found to significantly reduce neutrophil transendothelial migration in response to Conclusions: Our findings highlight the regulatory role of macrophages in modulating neutrophil responses, suggesting potential therapeutic targets to control neutrophil function in various diseases. The modified microfluidic platform offers a valuable tool for mechanistic studies into macrophage-neutrophil interactions in disease contexts.
