From Genetic Engineering News:
The Myelin Repair Foundation today announced that its collaboration of five of the world’s leading neuroscientists has identified three new “switches,” or signals, operating in the brain and spinal column that appear to turn on and off the nerve cell’s ability to repair myelin. Myelin is the protective coating surrounding nerve cells that is damaged by MS. The scientists’ findings are a critical first step in understanding myelin repair and its role in treatments for MS and other demyelinating diseases.
This discovery focuses on myelin in the brain and spinal cord and not the peripheral nerves, so though it’s not directly applicable to Dejerine-Sottas research, it’s another step in the right direction.
