Researchers Reverse Aspects of Aging to Increase Myelin Repair in Rats

November 5, 2019

Researchers from the UK and Australia have found a way to make rat brain cells act more youthful, reversing some of the loss of healing capacity that normally comes with older age.
 
Multiple sclerosis involves immune attacks that damage brain tissues, including the myelin coating on nerve fibers. The brain has its own resident stem cells, called OPCs, that can initiate myelin repair after damage. Robin Franklin, PhD, of the University of Cambridge, and others had previously shown that with greater age, OPCs lose the capacity to initiate myelin repair.
 
In a paper published in October 2019 in the journal Cell Stem Cell, Dr. Franklin and colleagues reported that in old rats, fasting made OPCs act more youthful, regaining capacity to repair myelin. The team also found that a diabetes drug called metformin, which can mimic some biological aspects of fasting, was able to reverse age-related changes to rat OPCs and increased their capacity to initiate myelin repair.
 
This study was funded in part by the UK MS Society. More research is underway to translate these important findings in rats into a myelin repair strategy for people living with MS.
 
Dr. Franklin was the recipient of the Barancik Prize for Innovation in MS Research in 2017.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable, often disabling disease of the central nervous system. There is currently no cure for MS. Symptoms vary from person to person and range from numbness and tingling, to mobility challenges, blindness and paralysis. An estimated 1 million people live with MS in the United States. Most people are diagnosed between the ages of 20 and 50, and it affects women three times more than men.
