Study Funded by The ALS Association Finds That Neurons Can Be Reprogrammed to Take on New Identities
WASHINGTON, Jan. 29, 2013 /PRNewswire-USNewswire/ — In work supported by The ALS Association and funded through The Milton Safenowitz Post-Doctoral Fellowship Program, researchers have for the first time reprogrammed a neuron from one type into another and have done so in a living organism. The finding will help scientists better understand how to control neuronal development and may one day aid in treating diseases in which neurons die, such as amyotrophic lateral sclerosis (ALS). The study was published in the journal Nature Cell Biology.
ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Eventually, people with ALS lose the ability to initiate and control muscle movement, which often leads to total paralysis and death within two to five years of diagnosis. There is no cure and no life-prolonging treatments for the disease.
“This discovery tells us again that the brain is a somehow flexible system and gives us more evidence that reprogramming neurons to take on new identities and, perhaps, that new functions are possible,” said Lucie Bruijn, Ph.D., Chief Scientist for The Association. “For those working to treat neurodegenerative diseases, that is reassuring.”
