Wnt5a‐Induced Exosomes From Bone Marrow Mesenchymal Stem Cells Promote Spinal Cord Injury Repair by Modulating Immune Cell Phenotypes and Alleviating Neuroinflammation via the NF ‐ κB Pathway

Key Points

This research aims to investigate how Wnt5a-induced exosomes affect spinal cord injury repair mechanisms.
Examine the role of Wnt5a in bone marrow mesenchymal stem cell (BMSC) exosome production.
Analyze the modulation of immune cell phenotypes by these exosomes.
Assess the impact on neuroinflammation via NF-κB pathway inhibition.
Wnt5a significantly enhances the neuroregenerative potential of BMSC-derived exosomes.
Exosomes alter immune cell phenotypes favorably for repair processes.
Inhibition of the NF-κB pathway correlates with reduced neuroinflammation.

Abstract

Collectively, these findings indicate that Wnt5a enhances the neuroregenerative potential of BMSC-Exos by modulating immune responses and suppressing neuroinflammation, likely through inhibiting the NF-κB signaling pathway.
