Following injury to the central nervous system the regenerating nerves need to regrow through the site of damage, but scarring in this area leads to the expression of proteins that inhibit axon growth. Proteins modified by the addition of chondroitin sulphates — a class of sugars — are one group of molecules involved in this inhibition. In the May Nature Neuroscience Lawrence Moon and colleagues at the Physiological Laboratory, University of Cambridge, UK report that chemical removal of these sugar groups permits regrowth through the injured site (Nat Neurosci 2001, 4:465-466).
