Immunosuppressive Effects of Multiple Myeloma-Derived Extracellular Vesicles Through T Cell Exhaustion.
Article in Cancer science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Extracellular vehicles (EVs) are reported to be involved in several processes relating to tumor progression, including angiogenesis, osteolysis, and drug resistance in multiple myeloma (MM). However, the role of EVs in the immune-suppressive milieu of MM is poorly understood. Here, we investigated the effects of MM-derived EVs on T cells, focusing on markers of T cell exhaustion. Using activated peripheral blood mononuclear cells from healthy donors, we observed immunosuppressive effects such as upregulated expression of immune checkpoint markers on CD8+ T cells treated with MM-derived EVs. Proteomic analysis identified several proteins, such as IL-8, SLC1A5, PIN2, and FSP1, associated with regulation of T cell exhaustion and chronic inflammation. Surprisingly, sphingosine kinase 1 (SPHK1) was enriched in MM cell line-derived EVs, implicating SPHK1/S1P signaling in the immunosuppressive effect of MM EVs. Thus, MM-derived EVs may promote T cell exhaustion via upregulating the expression of immune checkpoint markers and thereby contribute to the formation of the immune-suppressive milieu of MM, resulting in impaired T cell activity.
