Anti-inflammatory exosomal ncRNAs exert synergistic effects: miR-146a targets TLR4\/MyD88, miR-340-5p suppresses JAK2\/STAT3, and miR-16-5p is sponged by circZFHX3 to upregulate IGF-1, collectively shifting M1\u2192M2 polarization (elevating Arg1\/CD206, reducing iNOS\/CD16). Exosomal lncGm37494 acts as a ceRNA to sponge miR-130b-3p, upregulating PPAR\u03b3. Exosomal proteins (MFG-E8, IL-10) activate SOCS3\/STAT3, repairing the blood-spinal cord barrier. Targeted interventions (engineered\/MSC-derived exosomes) restore this balance, reducing glial scarring and improving motor function (BBB score elevation).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Exosomal ncRNA\/protein-mediated macrophage polarization and inflammatory pathway regulation are core molecular targets in SCI, offering biosciences-based strategies for precision therapy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmolb.2026.1787949","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T04:15:54Z","timestamp":1774930554000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Exosome-derived ncRNAs and proteins: inflammation regulatory mechanisms and biomarker potential in spinal cord injury"],"prefix":"10.3389","volume":"13","author":[{"given":"Yongliang","family":"Wang","sequence":"first","affiliation":[{"name":"Graduate School, Heilongjiang University of Chinese Medicine","place":["Harbin, Heilongjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Graduate School, Heilongjiang University of Chinese Medicine","place":["Harbin, Heilongjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinsheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Graduate School, Heilongjiang University of Chinese Medicine","place":["Harbin, Heilongjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuefeng","family":"Li","sequence":"additional","affiliation":[{"name":"Graduate School, Heilongjiang University of Chinese Medicine","place":["Harbin, Heilongjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinyu","family":"Zhao","sequence":"additional","affiliation":[{"name":"Graduate School, Heilongjiang University of Chinese Medicine","place":["Harbin, Heilongjiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixin","family":"Yang","sequence":"additional","affiliation":[{"name":"Hebei Key Laboratory of Nerve Injury and Repair, Chengde Medical University","place":["Chengde, Hebei, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1080\/10790268.2025.2503053","article-title":"Cerebrolysin-loaded platelet-rich plasma exosomes: restoring immune homeostasis via TNF-\u03b1\/IL-10 modulation and apoptosis targeting for spinal cord injury repair","volume":"49","author":"Akbari-Gharalari","year":"2025","journal-title":"J.
