BM-MSC-derived migrasomes reverse stroke-induced thymic atrophy and immunosuppression via Pin1 delivery to thymic epithelial cells.

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
Acute ischemic stroke triggers immunosuppression, yet existing therapies struggle to balance neuroprotection with poststroke immunosuppression. We demonstrated that bone marrow mesenchymal stem cells (BM-MSC) reverse stroke-induced thymic atrophy by promoting T-cell differentiation and restoring peripheral T-cell populations. Bulk RNA sequencing of BM-MSC-treated thymuses revealed enhanced proliferative signatures. Mechanistically, BM-MSC secrete migrasomes (organelles derived from migrating cells) that traverse the blood‒thymus barrier. Single-cell RNA sequencing analysis demonstrated that migrasome-mediated proliferation occurred specifically in medullary thymic epithelial cell I (mTECI) subpopulations. Proteomic profiling via liquid chromatography‒tandem mass spectrometry (LC‒MS/MS) identified Pin1-a cell cycle regulator-as the predominant cargo in BM-MSC-derived migrasomes. In vivo and in vitro studies confirmed migrasome-mediated thymic epithelial proliferation, T-cell niche reconstruction, and immune homeostasis restoration. Migrasome monotherapy improved neurological deficits and survival rates in stroke model mice, demonstrating dual neuroprotective-immunomodulatory efficacy. This work addresses the clinical dilemma between neuroprotection and immunosuppression alleviation, establishing migrasomes as a cell-free therapeutic strategy for poststroke immunotherapy.
