BETTER UNDERSTANDING THE MECHANISMS OF NEURODEGENERATIVE DISEASE

 

Congrats to all working on the project!  We are closer to understanding the molecular pathology at work in ALS!

CHAPEL HILL, NC – Scientists have long known that a protein called TDP-43 clumps together in brain cells of people with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, and is associated with neuron death. This same protein is thought to cause muscle degeneration in patients with sporadic inclusion body myositis (sIBM), leading many researchers to think that TDP-43 is one of the causative factors in ALS and sIBM. Now, UNC School of Medicine and NC State researchers found that a specific chemical modification called acetylation promotes TDP-43 clumping in animals. Using a natural anti-clumping method in mouse models, the scientists reversed protein clumping in muscle cells and prevented the sIBM-related muscle weakness.
