CXCL13 and migraine disorder: MicroRNA profiling identified a dysregulated miRNA signature converging on the transcription factor FOXO3, which indirectly regulated CXCR5 transcription, defining a miRNA-FOXO3-CXCR5 regulatory pathway.<h4>Conclusion</h4>Our study reveals the CXCL13/CXCR5/ERK axis as a previously unrecognized pathway in migraine neuroinflammation and demonstrates electroacupuncture's multimodal therapeutic mechanisms.
