Decidual Cells Induce Release of Free and Exosome-Bound Interferon Epsilon From Vaginal Epithelial Cells.
Article in American journal of reproductive immunology (New York, N.Y. : 1989), 2025. 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
problemWe tested the hypothesis that oxidative stress (OS)-induced inflammatory response in decidual cells (DECs) may transfer and/or trigger the release of interferon epsilon (IFNε)-positive extracellular vesicles (EVs) from vaginal epithelial cells (VECs) to minimize vaginal disturbances. METHOD OF STUDY: VECs were treated for 48 h under the following conditions: (1) standard VEC media, (2) OS-inducing cigarette smoke extract (CSE); and supernatant from (3) normal/untreated DECs, and (4) CSE-treated DECs. The concentration of cytoplasmic, secreted, and VEC-derived EV bound IFNε (n = 3 each) was measured by enzyme-linked immunosorbent assay (ELISA). EVs were isolated from culture media by cushioned-density gradient ultracentrifugation and characterized by immunoblotting and nanoparticle tracking analysis.
resultsInduction of OS in VECs with CSE increased intracellular IFNε in VECs (p = 0.0007) but not free or EV-bound IFNε compared to control VECs. Exposure to conditioned media from untreated and CSE-treated DECs induced increased intracellular (p = 0.004, p = 0.049) and free IFNε (p = 0.04, p = 0.03) from VECs. VEC-derived EVs (126 ± 11.8 nm) expressed exosome markers, and did not change in size regardless of the treatment but decreased in number due to exposure to untreated (p = 0.004) and CSE-treated DECs (p = 0.025) conditioned media. Furthermore, VEC exosomal IFNε increased by 2.6-fold (p = 0.0001, untreated DECs) and ∼4-fold (p = 0.041, CSE-treated DECs) compared to controls.
conclusionsMucosal immune defense mediated by IFNε may be an innate response by VECs under OS. This was further evidenced by an overall increase in IFNε due to both physiologic and pathologic impact of decidua on VECs. IFNε may indicate a stress response by VECs or paracrine crosstalk between gestational tissues.
