Immune regulation in mitochondrial transfer: knowledge structure and emerging trends from a bibliometric perspective.
Synthesis in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Mitochondrial transfer has emerged as an important form of intercellular communication with growing relevance to immune regulation, inflammation, tissue repair, and tumor immunity. However, the knowledge structure, developmental trajectory, and emerging hotspots of this field remain unclear. Methods: We conducted a bibliometric analysis of studies on mitochondrial transfer and immune regulation published between 2016 and 2025. Publications were retrieved from PubMed, Embase, the Cochrane Library, Scopus, and Web of Science, and analyzed using bibliometrix in R and CiteSpace. Annual publication trends, contributions of countries, institutions, authors, and journals, as well as keyword co-occurrence, clustering, burst detection, and co-citation patterns were evaluated. Results: A total of 967 publications were included. Annual publication output increased steadily, with faster growth after 2020. China and the United States were the leading contributors and occupied central positions in international collaboration networks. Keyword and co-citation analyses showed that early studies mainly focused on mitochondrial DNA-associated inflammatory sensing, innate immunity, and inflammatory injury, whereas recent studies increasingly emphasized intercellular mitochondrial transfer, mitochondrial transplantation, T-cell function, tumor-associated macrophages, cancer immunotherapy, metabolic rewiring, and autophagy-associated mitochondrial quality control. Mitochondrial transplantation and tunneling nanotube were among the most prominent burst terms. Co-citation analysis identified major knowledge domains related to mitochondrial danger signaling, intercellular transfer mechanisms, mesenchymal stem cell-mediated immune regulation, tumor immunity, and translational applications. Conclusion: Bibliometric mapping shows a clear shift from mitochondrial danger signaling toward intercellular transfer and immune-cell metabolic remodeling. Current evidence suggests that immune outcomes are shaped by mitochondrial source, transfer route, recipient-cell state, and disease context. More source-defined and context-specific studies are needed to clarify the therapeutic potential of mitochondrial transfer.
