Harnessing Spinal Interneurons for Spinal Cord Repair

Abstract

Interest in spinal interneurons (SpINs), their heterogeneity in the naive spinal cord and their varying responses to central nervous system injury or disease has been steadily increasing. Our recent review on this topic highlights the vast phenotypic heterogeneity of SpINs and the efforts being made to better identify and classify these neurons. As our understanding of SpIN phenotype, connectivity, and neuroplastic capacity continues to expand, new therapeutic targets are being revealed and novel treatment approaches developed to harness their potential. Here, we expand on that initial discussion and highlight how SpINs can be used to develop advanced, targeted cellular therapies and personalized medicines.
