Acute lymphoblastic leukemia-derived exosome inhibits cytotoxicity of natural killer cells by TGF-β signaling pathway.
Article in 3 Biotech, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 11 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
This study was conducted to explore whether acute lymphoblastic leukemia (ALL)-derived exosomes affect natural killer (NK) cells. Exosomes were isolated and identified from Jurkat cells and co-cultured with NK cells. Then, the cytotoxicity, viability, and release of perforin and granzyme B in NK92-MI cells were measured. PCR arrays were used to detect gene expression alterations in the transforming growth factor (TGF)-β pathway of NK92-MI cells treated or not treated with exosomes. The morphology and size of the exosomes isolated from Jurkat cells showed typical characteristics of exosomes, and the expression of cluster of differentiation 63 was detected. Jurkat-derived exosomes were internalized by NK92-MI cells, further inhibiting the proliferation and cytotoxicity of NK92-MI cells. An enzyme-linked immunosorbent assay revealed that the release of perforin and granzyme B from NK92-MI cells decreased after co-culture with exosomes. Similarly, western blot and immunofluorescence staining verified that Jurkat-derived exosomes inhibited the expression of granzyme B and perforin. Furthermore, Jurkat-derived exosomes enhanced the signaling of the TGF-β pathway in NK92-MI cells via the MDS1 and EVI1 complex loci and homeodomain interacting protein kinase 2. In conclusion, we found that ALL-derived exosomes inhibit the biological function of NK cells and provide support for the immunotherapy of ALL.
