It was implicated that nerve cells, once damaged, are incapable of regeneration. Damage to the nervous system can often cause a person to be paralyzed. This has been a big challenge medical science has been confronting since many years. Broken nerves are incapable to regenerate neurons and this hampered movement and other important activities. After years of research, neurologists have found a gene that is associated with regeneration of injured nerve cells. The regenerating capability of axons, the messengers of the neurological system, is suppressed by mutation in a single gene which shuts down the process of regrowth. Axons ideally survive throughout an animal’s lifetime by being resilient. In the event of injury or simple wear and tear, some axons hold the capability to rejuvenate. Microtubules are being considered to play a major role as remodelling proteins in axon repair after injury. Spastin, a protein component of microtubule, is thought to play a major role in this event. This breakthrough has opened the doors to new research related to spinal-cord and other neurological disorders in humans although a lot of work still needs to be done.
