Research Abstract |
Based on the observation that inhibition of Glycogen Synthase Kinase-3(GSK-3) stimulates the migration of astrocytes, the applicant was able to pharmacologically stimulate this beneficial effect of reactive astrocytes : the administration of a specific inhibitor of GSK-3 after contusive SCI resulted in an accelerated migration of reactive astrocytes that secluded inflammatory cells, reduced the size of the lesions scar, spared more myelinated fibers, and significantly enhanced functional improvement. These findings suggest that the pharmacological stimulation of reactive astrocyte migration holds promise as a new therapeutic strategy for the treatment of spinal cord injury.
