Chondroitin sulfate proteoglycans (CS-PGs) are axon growth inhibitory molecules present in the glial scar that are responsible (at least in part) for regeneration failure after CNS or spinal cord injury. Removal of chondroitin sulfate glycosaminoglycan chains using the bacterial enzymes chondroitinase-ABC or AC in models of CNS injury promotes both axon regeneration and plasticity. The present invention relates to the use of members of the human hyaluronidase family (endo-beta-acetyl-hexosaminidase enzymes, E.C. 3.2.1.35) for the degradation of chondroitin sulfate (proteoglycans) in the glial scar to promote axonal regrowth in human CNS or spinal cord injury. The present invention also relates to methods for determining endoglycosidase activity, and in particular of the hyaluronidase/chondroitinase type, in a sample, and also relates to methods for detecting compounds that modulate the activity of endoglycosidases and in particular endoglycosidases of the hyaluronidase/chondroitinase type. |
