Lipid nanotubes unmask neutrophils for complement attack.
Article in Blood, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
abstractNeutrophils, critical components of innate immunity, undergo significant morphological changes during phagocytosis. In this study, we demonstrate that neutrophils exposed to shear stress generate lipid nanotubes (NTs) with a unique composition. Compared with the proteome of whole neutrophils, NTs notably lack cytoskeletal elements and the complement-inhibiting transmembrane protein CD46. Consequently, these NTs are recognized by the complement system and selectively opsonized the complement component C3b. Biophysical characterization of NTs confirmed that their integrity relies on lipid-lipid interactions and that they pinch off from neutrophils to form NT-derived vesicles (NTDVs). We detected C3b+ NTDVs in plasma from patients and animal models experiencing diverse inflammatory conditions, including metastatic melanoma, vasculitis, and polytrauma. Further functional experiments indicate that resting neutrophils phagocytose complement-opsonized NTDVs, leading to cell activation, including the production of reactive oxygen species. In conclusion, our data suggest a significant role for neutrophil-derived NTs in a wide range of inflammatory diseases and reveal a previously unknown mode of cell-cell communication.
