Coaxing Injured Nerve Fibers to Regenerate by Disabling ‘Brakes’ in the System

<p>ScienceDaily (Dec. 10, 2009) &mdash; Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Children’s Hospital Boston, published in the December 10 issue of the journal Neuron, shows that axons can regenerate vigorously in a mouse model when a gene that suppresses natural growth factors is deleted…</p>
