Chondroitinase ABC Enhances Pericontusion Axonal Sprouting But Does Not Confer Robust Improvements in Behavioral Recovery

Delivery of Thermostabilized Chondrotinase Abc Enhances Axonal Sprouting and Functional Recovery after Spinal Cord Injury

Chondroitinase ABC promotes recovery of adaptive limb movements and enhances axonal growth caudal to a spinal hemisection.

A number of studies have shown that chondroitinase ABC (Ch'ase ABC) digestion of inhibitory chondroitin sulfate glycosaminoglycans significantly enhances axonal growth and recovery in rodents following spinal cord injury (SCI). Further, our group has shown improved recovery following SCI in the larger cat model. The purpose of the current study was to determine whether intraspinal delivery of C...

Chondroitinase ABC enhances axonal regrowth through Schwann cell-seeded guidance channels after spinal cord injury.

Grafting of Schwann cell-seeded channels into hemisected adult rat thoracic spinal cords has been tested as a strategy to bridge the injured cord. Despite success in guiding axonal growth into the graft, regeneration across the distal graft-host interface into the host spinal cord was limited. We hypothesized that chondroitin sulfate (CS) glycoforms deposited at the gliotic front of the interfa...

Chondroitinase ABC Administration in Locomotion Recovery After Spinal Cord Injury: A Systematic Review and Meta-analysis

Introduction: The present systematic review and meta-analysis aims to conduct a comprehensive and complete search of electronic resources to investigate the role of administrating Chondroitinase ABC (ChABC) in improving complications following Spinal Cord Injuries (SCI). Methods: MEDLINE, Embase, Scopus, and Web of Sciences databases were searched until the end of 2019. Two independent reviewe...

Lentiviral vectors express chondroitinase ABC in cortical projections and promote sprouting of injured corticospinal axons

Several diseases and injuries of the central nervous system could potentially be treated by delivery of an enzyme, which might most effectively be achieved by gene therapy. In particular, the bacterial enzyme chondroitinase ABC is beneficial in animal models of spinal cord injury. We have adapted the chondroitinase gene so that it can direct secretion of active chondroitinase from mammalian cel...
