MicroRNAs (miRNAs). Key epigenetic regulators of immune and neuronal pathways may contribute to these differences, but sex is rarely examined as a primary biological variable in MS miRNA research. This exploratory pilot study characterized sex-specific miRNA expression in treatment-na\u00efve individuals with RRMS using samples from 46 participants (17 males and 17 females with RRMS; 6 male and 6 female healthy controls) obtained from the Accelerated Cure Project biorepository. miRNA expression was quantified using the NanoString nCounter Human v3 panel, and differential expression (\n                    <jats:italic toggle=\"yes\">p &lt;<\/jats:italic>\n                    0.05, fold-change \u22651.3) was evaluated across four comparisons: Multiple sclerosis (MS) females vs. MS males; sex-matched MS vs. control groups; and female vs. male healthy controls. Distinct sex-biased miRNA signatures emerged. Males with RRMS demonstrated dysregulation of immune-associated miRNAs, including coordinated changes in the miR-29, miR-30, and miR-199 families. Females with RRMS exhibited consistent downregulation of miR-941 and differential expression of immune-associated miRNAs including miR-223-3p, miR-485-3p, and miR-199a-5p. Several immune-regulatory miRNAs, including miR-223-3p, miR-146a-5p, miR-196b-5p, and miR-183-5p, were differentially expressed in both healthy controls and disease-related comparisons, suggesting that sexually dimorphic immune regulatory programs may precede disease onset. These findings indicate that disease-associated miRNA alterations are superimposed on pre-existing sex-specific immune networks and underscore the importance of incorporating sex as a biological variable in biomarker discovery and precision medicine for MS.\n                  <\/jats:p>","DOI":"10.1177\/10998004261473903","type":"journal-article","created":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T09:11:11Z","timestamp":1787303471000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Differential microRNA Expression Reveals Sex-Specific Neuroinflammatory and Neurodegenerative Pathways in MS"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8794-8341","authenticated-orcid":false,"given":"Stephanie","family":"Buxhoeveden","sequence":"first","affiliation":[{"name":"Virginia Commonwealth University School of Nursing"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theresa","family":"Swift-Scanlan","sequence":"additional","affiliation":[{"name":"Virginia Commonwealth University School of Nursing"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8064-521X","authenticated-orcid":false,"given":"Amy","family":"Olex","sequence":"additional","affiliation":[{"name":"Virginia Commonwealth University C.
