Researchers have found a possible mechanism for re-growing damaged nerve fibres in the central nervous system (CNS). Currently this kind of damage is irreparable, leaving those who have suffered a spinal cord injury, stroke or brain trauma with serious impairments like loss of sensation and permanent paralysis. Published in Nature Communitcations, the research highlights the role of a protein called P300/CBP-associated factor (PCAF), which appears to be essential for the series of chemical and genetic events that allow nerves to regenerate.Researchers found that when they injected PCAF into mice with damage to their CNS, the amount of nerve fibres that grew back increased.
It’s an exciting time for science and the human body. What a gift it would be for someone who is paralyzed to be able to walk again on their own. I can’t wait to see what happens next we will probably have cyborg bodies!
