Barriers to axonal regeneration after spinal cord injury:a current perspective

Neural Regeneration Research 2022年第1期17卷 85-86页

作者： jacek M.Kwiecien Department of Pathology and Molecular Medicine Faculty of Health SciencesMcMaster UniversityHamiltonOntarioCanada

Regeneration of long axons after the spinal cord injury(SCI)will benefit patients with extensive traumatic damage to the white matter pathways who experience intolerable,permanent,neurologic deficits even after neuroprotective treatment with anti-inflammatory agents(Kwiecien,2021a).This short paper attempts to synthetize pathologic mechanisms or barriers involved in inhibition of axonal regeneration in the SCI and provides suggestions of therapeutic interventions enabling this regeneration in animal models.
